Duration of studies and dedication regime

Duration
The maximum period of study for full-time doctoral studies is three years, counted from the date of admission to the programme to the date of submission of the doctoral thesis. The academic committee of the doctoral programme may authorise a doctoral candidate to pursue doctoral studies on a part-time basis. In this case, the maximum period of study is five years, counting from the date of admission to the programme to the date of submission of the doctoral thesis. For calculating these periods, the date of admission is considered to be the date of the first enrolment for tutorials, and the date of submission the moment in which the Doctoral School officially deposits the doctoral thesis.

For full-time doctoral candidates, the minimum period of study is two years, counted from the date of an applicant's admission to the programme until the date on which the doctoral thesis is deposited; for part-time doctoral candidates it is four years. When there are justified grounds for doing so, and the thesis supervisor and academic tutor have given their authorisation, doctoral candidates may request that the academic committee of their doctoral programme exempt them from the minimum period of study requirement.

The calculation of periods of study will not include periods of absence due to illness, pregnancy or any other reason provided for in the regulations in force. Students who find themselves in any of these circumstances must notify the academic committee of the doctoral programme, which, where appropriate, must inform the Doctoral School. Doctoral candidates may also temporarily withdraw from the programme for up to one year, and this period may be extended for an additional year. Doctoral candidates who wish to interrupt their studies must submit a justified request to the academic committee of the doctoral programme, which will decide whether or not to approve the request. Each programme will establish conditions for readmission to doctoral studies.

Extension
If full-time doctoral candidates have not applied to deposit their thesis by the end of the three-year period of study, the academic committee of the programme may authorise an extension of up to one year. In exceptional circumstances, a further one-year extension may be granted, subject to the conditions established by the corresponding doctoral programme. In the case of part-time doctoral candidates, an extension of two years may be authorised. In both cases, in exceptional circumstances a further one-year extension may be granted by the Doctoral School's Standing Committee, upon the submission of a reasoned application by the academic committee of the doctoral programme.

Dismissal from the doctoral programme
A doctoral candidate may be dismissed from a doctoral programme for the following reasons:

• The doctoral candidate submitting a justified application to withdraw from the programme.
• The maximum period of study and of extensions thereof ending.
• The doctoral candidate not having enrolled every academic year (unless he or she has been authorised to temporarily withdraw).
• The doctoral candidate failing two consecutive assessments.
• The doctoral candidate having disciplinary proceedings filed against him or her that rule that he or she must be dismissed from the UPC.

Dismissal from the programme implies that doctoral candidates cannot continue studying at the UPC and the closing of their academic record. This notwithstanding, they may apply to the academic committee of the programme for readmission and the committee must reevaluate them in accordance with the criteria established in the regulations.

Enrollment aid

The programme does not provide any specific grants to cover enrolment fees. In exceptional cases, research groups may offer one-off grants.

Procedure for the preparation and defense of the research plan

Doctoral candidates must submit a research plan, which will be included in their doctoral student activity report, before the end of the first year. The plan may be improved over the course of the doctoral degree. It must be endorsed by the tutor and the supervisor, and it must include the method that is to be followed and the aims of the research.

At least one of these annual assessments will include a public presentation and defence of the research plan and work done before a committee composed of three doctoral degree holders, which will be conducted in the manner determined by each academic committee. The examination committee awards a Pass or Fail mark. A Pass mark is a prerequisite for continuing on the doctoral programme. Doctoral candidates awarded a Fail mark must submit a new research plan for assessment by the academic committee of the doctoral programme within six months.

The committee assesses the research plan every year, in addition to all of the other activities in the doctoral student activity report. Doctoral candidates who are awarded two consecutive Fail marks for the research plan will be obliged to definitely withdraw from the programme.

If they change the subject of their thesis, they must submit a new research plan.

Procedure for assignment of tutor and thesis director

The academic committee of the doctoral programme assigns a thesis supervisor to each doctoral candidate when they are admitted or enrol for the first time, taking account of the thesis supervision commitment referred to in the admission decision.

The thesis supervisor will ensure that training activities carried out by the doctoral candidate are coherent and suitable, and that the topic of the candidate’s doctoral thesis will have an impact and make a novel contribution to knowledge in the relevant field. The thesis supervisor will also guide the doctoral candidate in planning the thesis and, if necessary, tailoring it to any other projects or activities undertaken. The thesis supervisor will generally be a UPC professor or researcher who holds a doctoral degree and has documented research experience. This includes PhD-holding staff at associated schools (as determined by the Governing Council) and UPC-affiliated research institutes (in accordance with corresponding collaboration and affiliation agreements). When thesis supervisors are UPC staff members, they also act as the doctoral candidate’s tutor.

PhD holders who do not meet these criteria (as a result of their contractual relationship or the nature of the institution to which they are attached) must be approved by the UPC Doctoral School's Standing Committee in order to participate in a doctoral programme as researchers with documented research experience.

The academic committee of the doctoral programme may approve the appointment of a PhD-holding expert who is not a UPC staff member as a candidate’s thesis supervisor. In such cases, the prior authorisation of the UPC Doctoral School's Standing Committee is required. A UPC staff member who holds a doctoral degree and has documented research experience must also be proposed to act as a co-supervisor, or as the doctoral candidate’s tutor if one has not been assigned.

A thesis supervisor may step down from this role if there are justified reasons (recognised as valid by the committee) for doing so. If this occurs, the academic committee of the doctoral programme will assign the doctoral candidate a new thesis supervisor.

Provided there are justified reasons for doing so, and after hearing any relevant input from the doctoral candidate, the academic committee of the doctoral programme may assign a new thesis supervisor at any time during the period of doctoral study.

If there are academic reasons for doing so (an interdisciplinary topic, joint or international programmes, etc.) and the academic committee of the programme gives its approval, an additional thesis supervisor may be assigned. Supervisors and co-supervisors have the same responsibilities and academic recognition.

The maximum number of supervisors of a doctoral thesis is two: a supervisor and a co-supervisor.

For theses carried out under a cotutelle agreement or as part of an Industrial Doctorate, if necessary and if the agreement foresees it this maximum number of supervisors may not apply. This notwithstanding, the maximum number of supervisors belonging to the UPC is two.

Permanence

The academic committee of the programme may authorise an extension of up to one year for full-time doctoral candidates who have not applied to deposit their thesis by the end of the three-year period of study, in the terms outlined in the Academic Regulations for Doctoral Studies of the Universitat Politècnica de Catalunya. In the case of part-time candidates, an extension of two years may be authorised. In both cases, in exceptional circumstances a further one-year extension may be granted by the Doctoral School's Standing Committee, upon the submission of a reasoned application by the academic committee of the doctoral programme.

A doctoral candidate may be dismissed from a doctoral programme for the following reasons:

• The doctoral candidate submitting a justified application to withdraw from the programme.
• The maximum period of study and of extensions thereof ending.
• The doctoral candidate not having enrolled every academic year (unless he or she has been authorised to temporarily withdraw).
• The doctoral candidate failing two consecutive assessments.
• The doctoral candidate having disciplinary proceedings filed against him or her that rule that he or she must be dismissed from the UPC.

Dismissal from the programme implies that doctoral candidates cannot continue studying at the UPC and the closing of their academic record. This notwithstanding, they may apply to the academic committee of the programme for readmission and the committee must reevaluate them in accordance with the criteria established in the regulations.

International Mention

The doctoral degree certificate may include International Doctorate mention. In this case, the doctoral candidate must meet the following requirements:

a) During the period of study leading to the award of the doctoral degree, the doctoral candidate must have spent at least three months at a respected higher education institution or research centre outside Spain to complete courses or do research work. The stays and activities carried out must be endorsed by the thesis supervisor and authorised by the academic committee of the programme. The candidate must provide a certifying document issued by the person responsible for the research group of the body or bodies where the stay or activity was completed. This information will be added to the doctoral student’s activity report.
b) Part of the thesis (at least the summary and conclusions) must be written and presented in one of the languages commonly used for science communication in the relevant field of knowledge, which must not be an official language of Spain. This rule does not apply to stays and reports in Spanish or to experts from Spanish-speaking countries.
c) At least two PhD-holding experts belonging to a higher education institution or research centre outside Spain must have issued officially certified reports on the thesis.
d) The thesis examination committee must have included at least one PhD-holding expert from a higher education or research institution outside Spain who was not responsible for the candidate’s stay abroad (point a) above).
e) The thesis defence must have taken place on UPC premises or, in the case of joint programmes, at the location specified in the collaboration agreement.

  Thesis abstract: In this thesis, the ability to refine the grain size of a low carbon steel (deep drawing quality, DDQ) was studied by means of two different techniques of Severe Plastic Deformation (SPD). Firstly, the Repetitive Corrugated and Straightening (RCS) technique using a die designed for this project. Likewise, a Finite Element Analysis (FEA) was carried out to establish processing routes that would guarantee an optimal distribution of the deformation throughout the entire sheet. The second technique chosen was Calibrated Groove Pressing (CGP), for which a classic die design, with walls to restrict motion in both directions, was chosen. Both processes were carried out at room temperature and with lubricant throughout the process. Two processing routes were established for each of the techniques, reaching different levels of deformation in each of them. To know the mechanical response of the material after being processed, Vickers hardness and tensile tests were carried out. In addition, drawing tests were carried out to know the resulting ability of the material to be shaped. The microstructural characterization was carried out by means of the Electron Backscattered Diffraction (EBSD) technique, to determine the ability to obtain ultrafine grain size, and the strain distribution and texture evolution. The study of mechanical properties revealed the increase in mechanical strength of the material by increasing the deformation, for both techniques. However, the elongation capacity of the material was severely reduced, causing a great loss of drawability in the final material. According to the microstructural results, the evolution of the grain size refinement was observed for each of the different routes and techniques. The grain size reduction depends directly on the increment of the fraction of low and high angle grain boundaries, which varied as the deformation progressed. The morphology, distribution, and grain size, as well as the stored deformation, modified the texture of the material, obtaining intense textures with distributions along the fibers with a shear and lamination texture orientation.

  Thesis abstract: Mimicking bone extracellular matrix (ECM) is essential to improve cell-material interactions. In this regard, the functionalization of materials with biomolecules derived from the bone ECM is a promising approach. In particular, the use of integrin binding molecules in combination with growth factors (GFs)-derived peptides involved in the bone regeneration process, i.e.,BMP-2-derived peptides, can be employed to install bioactivity in biomaterials and reproduce the bone ECM microenvironment.Based on these evidences, the present PhD Thesis focuses on the development of a multifunctional biomimetic peptide integrating the well-known RGD motif and the osteogenic DWIVA sequence derived from the wrist epitope of BMP-2 in a spatially controlled manner, and its use to functionalize different types of biomaterials. This molecule, identified as the RGD-DWIVA biomimetic peptide, is the central core of this PhD Thesis.In Chapter I, functionalization of glass model substrates with the engineered biomimetic peptide is performed. The biological behavior as well as the capacity to synergistically promote integrin/GF signaling of such biomimetic interfaces are then evaluated with C2C12 myoblasts. The results demonstrate the potential of RGD-DWIVA to enhance C2C12 cell adhesion, their transdifferentiation towards the osteogenic lineage and the activation of Smad-independent signaling pathways. Next, with the purpose of finding new BMP-2-derived sequences with osteogenic potential, a small library of synthetic peptides is reported. The osteogenic capacity of these peptides then is screened using the C2C12 cellular model. To our surprise, peptides with better biological properties than DWIVA are not identified, and, therefore, the RGD-DWIVA peptide is continued to be used and evaluated with human mesenchymal stem cells (MSCs), showing an improvement in cell adhesion and osteogenic differentiation.On the basis of the successful results with MSCs, the PhD Thesis further explores in Chapter II the application of the biomimetic peptide to more clinically relevant biomaterials, i.e., titanium. The extraordinary affinity of the anchoring unit of the peptides to metallic oxides is demonstrated by different physicochemical methods. In addition, the biological effects associated to the cyclization of either one (cRGD-DWIVA) of both bioactive motifs (cRGD-cDWIVA) in comparison to the RGD-DWIVA is also studied. To go a step further, the resulting biomimetic peptides are used to functionalize titanium implants, which are implanted in a rat calvarial deffect. Subsequently, the capacity of the engineered peptides to promote new bone formation and reduce fibrous tissue in vivo is assessed.Chapter III focuses on the translation of the previous strategy from 2D to 3D microenvironments. In this regard, two different hydrogels are studied: alginate and polyethylene glycol (PEG). As preliminary studies, functionalization of both hydrogels with an RGD-model peptide is performed. The rationale behind this approach is to compare the properties of the hydrogels, i.e., composition or mechanical properties, among others. As a result of this study, novel biodegradable PEG hydrogels are selected and further modified with the cRGD-DWIVA and cRGD-cDWIVA biomimetic peptides. A comprehensive physicochemical characterization of the hydrogels is performed, followed by the evaluation of their biological potential, demonstrating their capacity to trigger cell spreading and osteogenic differentiation of MSCs.In summary, using our multifunctional biomimetic peptides we were able to mimic the bone ECM (both in 2D and 3D) without the use of GFs, which may pave the way for alternative GF-based treatments in bone tissue engineering.

  Thesis abstract: The engineering design process uses a systemic model that stands out for a common pattern that has evolved from Archer (1968), through French (1985), Nigel Cross (2000) and Michael F. Ashby (2009). Although in this design process the engineer applies different methods, techniques and tools for the selection of an optimal material, to date, these do not place materials science as a starting point in the design process. Additionally, an industrial revolution that comes from understanding a new material, energy and technological scale is happening. It is defined as the nanoscale by recent scientific advances in various areas of knowledge such in the field of materials.It is a historical moment in which there are more scientific discoveries from new materials than those obtained in previous historical periods. Therefore, the need to face the design process from an approach that positions advanced materials as an engine of innovation is considered relevant. This creates a challenge since this industrial revolution, by coexisting with an accelerated pace of technological, scientific and social development, requires a vision in which materials are not only considered in the final stages of selection but from the beginning of the design process in a transversal way. This challenge requires that the advanced materials must be considered in the starting point in the design process to inspire the creation of innovative future scenarios. In this framework, one of the clearest examples of materials is graphene. Research on graphene and graphene materials is one of the fastest growing areas and although it is in the process of research and development, it augurs a great disruptive potential. The main objective of this Doctoral Thesis is to define a systemic model in an engineering design process that considers advanced materials from the beginning. This process must be carried out from a scientific perspective that seeks to understand the innovative possibilities to generate future advanced proposals. This research is structured in four main blocks:First, the research framework is defined so that this document exposes the thinking of an engineering professional in reference to significant scientific discoveries in the history, processes and theories related to the subject of study. Additionally, define what advanced materials are of interest for the work of this doctoral thesis.Second, the process in design for using advanced materials is determined, implemented and analytically studied using qualitative and quantitative methods.Third, one of the main success stories and results of this doctoral thesis is described, which highlights both the defined process and use of two-dimensional materials.Fourth, the process is detailed through a map of the results obtained.In summary, this document exposes the theoretical and experimental application of the transdisciplinary systemic model proposed to introduce advanced materials during de design and engineering process, specifically in the scientific exploration of smart inks. Then, it presents a success case study generated during the thesis: Smart Skin Tattoo, an ultrawearable of epidermal, non-invasive and ephemeral electronics that allows storing and generating personal data in a non-invasive way without the need to incorporate energy supply systems and that was implemented in a real event with people. Finally, the process for the granting of a patent related to the design of the Smart Skin Tattoo technology is shown, with reference P201830504 and with the title of "Communication device intended to be placed on the skin of a user".

  Thesis abstract: Labels misplacement in the bottles are currently causing problems in wine cellar's labelling lines. According to data provided by Codorníu and Torres cellars, 1% of the bottles present this issue. Once the wine or cava have been bottled, the bottles pass through the labeling station and the scanner separates the correctly labeled bottles from those with imperfections. When a considerable number of bottles are involved, the wine is emptied and rebottled, while the labeled bottle is discarded. However, if few bottles are mislabeled, a worker manually removes the labels with a scraper and retums the bottles to the labeling line. Of course, this is a problem.In this thesis, a system has been developed consisting of a pressure-sensitive adhesive anda detaching station that allows the adhesive to be deactivated for easy removal of misplaced labels. The adhesive had to meet the current market requirements and to be easily peeled off easily in the detaching station to leave the bottle completely clean to it can be relabelled without being taken out of the labelling lines. As bottles are full when they pass through the detaching station, a technology that could quickly remove the labels from the bottles at 25ºC was required to avoid affecting the quality of the product. lt was designed to include a cleaning solution bath, a thermostatic, and a mechanical agitator. Several chemical components with different weight ratios were tested for the cleaning solution formulation to determine the most effective solution. The design of the adhesive was sub-divided into 5 parts. First, the influence of the soft monomers: n-butyl acrylate and 2- ethylhexyl acrylate influence was studied via semi-batch emulsion polymerization taking as a starting point a formulation recipe composed of n-butyl acrylate and acrylic acid. In the second part, the influence of including a hard monomer, such as acrylonitrile, was studied. In both studies it was observed that the adhesives showed poor water resistance. For it, in the third part, different polymerizable surfactants were studied as stabilizer of the emulsion and were compared with the conventional surfactant used in the base formulation. The use a polymerizable surfactant clear 1y increased the water resistance of the adhesives. Although the incorporation of 2-ethylhexyl acrylate showed better adhesive performance, the acrylonitrile showed better results in the detaching bath. For it, it was decided to continue the experiments introducing in the formulation the weight ratio of acrylonitrile that showed the best balance between the adhesive properties and its performance in the detaching bath and the polymerizable surfactant that showed the highest water resistance.In the fourth part, the optimization of the adhesive properties balance was carried out by the study of the influence of acrylic acid as functional monomer and the tert-dodecyl mercaptan as chain transfer agent. Clearly, the acrylic acid improved all adhesive properties. However, the maximum amount of acrylic acid testad only improved the shear resistance since with the gel content increase, the peel resistance and tack properties deceased. On the other hand, the chain transfer agent only improved the peel resistance and tack. Therefore, it was not possible to achieve a good performance among the three adhesive properties.Finally, the influence of adhesiva preparation process was investigated. In this case an improvement in the balance of adhesive properties was observed. Several of the pressure-sensitive adhesives carne close to current market requirements, as well as showing excellent results in the detaching station.
