Seminar | Green thermosets:  Nanocomposites of  Rosin/Maghnite | December 13, 2017 | 12:00h

 

 

Summary: 

The work that has been done in these last 3 months involved both the chemical modification of the Algerian nanoclay by an organophilic treatment and also the linking of the Rosin with an Ionic liquid and a poly ionic liquid in order to enhance the properties of the rosin and to make them more suitable for the preparation of the nanocomposites linked-rosin/nanoclay. FT-IR, NMR analysis confirmed the efficient linkage of the rosin with the ionic liquid and the poly ionic liquid. The TGA analysis showed a significant improvement in the thermal properties with a way higher thermal degradation temperature in the case of the linked compounds. Further investigation will be done for the potential applications.

Seminar | A Project on the History of Plastics in Portugal | November 8, 2017 | 12:15h

 

 

Summary: 

This talk aims to present an interdisciplinary project on aspects of the history of plastics in Portugal, by basing itself on technical-scientific, industrial, social-historical studies, as well as studies pertaining to the history of science and technology and material culture.

 

The project intends to perform a full history of plastics, in order to bring to light : the techno-scientific aspects of plastics (and its communication to the general public); the need to preserve plastic objects; the role of plastics in the development of the industrial design, not just as corporate strategy but also in everyday life; the relationship of the plastic industry with their bodies (local workers and elite) and other industries (electrical and glass); energy and environmental issues related to plastics. We plan to set up a museum, in Leiria, to carry out studies on conservation, historical, technological and scientific research of plastics.

 

One of the purposes of this project is to study the impact of plastics in the Portuguese society, since its arrival in the mid-1930’s, through Bakelite, the first true plastic, in an agricultural country, without chemical research and technology nor an industrial tradition, in contrast with the more advanced industrial nations, where plastic had already assumed its position as an emblem of modernity.

The plastics industry has come to occupy a prominent place in the economies of industrialized countries since the inter-war period until the present day. The talk will reflect on how this development should be put on display in museums with important collections of plastics objects. Starting with Baquelite Liz, a company located in Leiria- centre of Portugal- the birthplace of the plastics manufacturing industry, that has worked in plastics since 1940, our intent is to carry out tasks such as the surveying and cataloguing of its estate, respective manufacturing methods, in addition to its impact on the social and cultural life of the region, and expand this work to other similar businesses. On the other hand, special attention will be devoted to Portuguese collections of plastic materials.

Seminário | 4 Outubro, 12h15 | Fabrico Aditivo por Extrusão de Cerâmico Tradicional | CDRsp- IPLeiria

 

Resumo:

O fabrico aditivo de materiais cerâmicos, camada a camada, é um tema com espaço para investigação e desenvolvimento. No âmbito do projeto Direct.Ceramic, é objetivo para este trabalho desenvolver um estudo preliminar acerca do comportamento do material cerâmico faiança quando associado ao fabrico aditivo por extrusão, ou impressão tridimensional. A metodologia utilizada para o fim proposto é baseada na impressão, em barbotina, de formas geométricas simples como cilindros ou prismas, consequente análise das suas dimensões antes e após etapas de processamento características destes materiais e avaliação do efeito da variação de alguns parâmetros da impressão tridimensional (velocidade de avanço, altura de camada, diâmetro de extrusão) na geometria e no aspeto das peças impressas. É efetuada análise estatística dos resultados obtidos. Concluiremos que a impressão 3D, de material cerâmico, não é bem-sucedida com o processo utilizado e que todos os parâmetros em variação influenciam a espessura de cada camada impressa.

From micro to nano: a pathway to tailor biomedical applications  

 

Summary

Only the complexity of human tissues could justify that in the 80’s Tissue Engineering (TE) emerged as a scientific field with an enormous potential. Targeting to regenerate bone, cartilage, skin, or other tissues and organs, bridging the anatomy with its physiology/function is a paramount challenge to be solved. Several efforts have been made, by research groups spread worldwide, to develop constructs that could mimic native tissues. Due to its nature TE gathers scientists, engineers and physicians in multidisciplinary teams using a variety of methods to construct biological substitutes. While there are different approaches used for TE, the most emergent and promising method is biofabrication. We have recently defined it as “the automated generation of biologically functional products with structural organization from living cells, bioactive molecules, biomaterials, cell aggregates such as micro-tissues, or hybrid cell-material constructs, through Bioprinting or Bioassembly and subsequent tissue maturation processes”.

Bioprinting is attracting a lot of research teams presenting an exponential increase in published works for the last 3 years. Meanwhile, 3D bioprinting market was valued at $98.6 million in 2015, and an annual grow of 36% for the next 6 years is expected. The existing and expected progress on printing technology will be presented.

Mimicking the double scale wrinkles of 2D surfaces for 3D printing

 

Summary

The 3D printing of scaffolds of polymeric materials has reached its cruise phase. Nevertheless, in order to really explore all the features of polymeric additive manufacturing some challenges still remain unsolved, namely the ability to produce the desired 3D architecture but with the appropriate topographic surface. This challenge is upraised when considering that most of the developed work indicates that sub-micron and nanometric topographies are most relevant for the interaction of the produced biomaterial with the eukaryotic cells. In this presentation it is exemplified the production of double scale wrinkled surfaces, by sputtering, with different chemistry obtained by using graphite and polyamide targets. The influence of chemical and topographic cues was evaluated by studying their interface with rat embryo cortex cells.

Seminar | 20 September, 12h00 | Project coolGRAFENO – graphene as solution for micro mold rapid cooling: constructal optimization | CDRSP-IPLEIRIA

 

Summary

The mold cooling is one of the most important phases in the molding cycle, comprising more than half of the total cycle time. This affects the final quality of the part and the production rate of the mold. Therefore, the design of a mold cooling channel system is essential to improve its thermal management and achieve a better control over the cycle time. The hardening of small thin wall plastic parts with complex geometries is one of the most challenging problems in the plastics injection industry, since we need to ensure quality, distortion-free plastic parts. The solution lies in optimizing the cooling system, changing materials and developing unconventional geometries compatible with the geometry of the part.

Seminar | 19 April, 12h00 | Industrial Mathematics: a key technology for driving innovation

 

Summary

Mathematics underpins all of modern science and technology. However, advances in mathematical research are not always applied to maximum advantage in industry. Since 2007, the mathematical community in Portugal has been promoting, on a yearly basis, study groups with industry. The purpose of these one-week meetings is to strengthen the links between academia and industry by using mathematics to tackle the challenges proposed by the industrial partners. Irrespectively or how successful these internationally recognised problem-solving forums are for knowledge transfer between mathematics and industry, it is only coupled with other initiatives that their outcome will have a lasting positive influence on the productive sector.

In this talk, we will give an overview of the study groups held in Portugal to date and report progress towards building efficient interactions between industry and academic mathematicians in Europe. In particular, we will present the activities that are being undertaken by several European institutions like ECMI (European Consortium for Mathematics in Industry) and discuss strategies to facilitate more effective widespread application of mathematics to all industrial sectors.

In the last part of this talk, we will present a project that brings together mathematicians, physicists, engineers and medical doctors, concerned with the characterization of the ageing process of the retina as detected by imaging techniques as the Optical Coherence Tomography  in health and disease.

Seminário | 12 Abril, 12h00 | PRODUÇÃO CENTRADA NO SER HUMANO: A perspetiva da ergonomia

 

Resumo

As intervenções ergonómicas podem assumir um potencial considerável para a melhoria da saúde músculo-esquelética no trabalho, através da análise global do sistema de trabalho. Os estudos realizados nas últimas décadas em situações de trabalho industrial, constituem, ainda hoje, um referencial para caracterizarmos este tipo de situações. As imposições de tempo, de repetitividade gestual, de execução de sequências operatórias e a sua afectação com carácter exclusivo a cada operador, de manutenção de posições estáticas, não obstante a necessidade permanente de organização postural, poderão, no seu conjunto, ter consequências múltiplas, entre as quais, a ocorrência de disfunções músculo-esqueléticas. É neste sentido que se pode afirmar que as lesões músculo-esqueléticas não são um problema isolado. Uma intervenção ergonómica terá como base a construção progressiva de um conhecimento, cimentado quer no conhecimento do sistema de produção, na sua globalidade, quer na consequente análise das situações de trabalho que serão objecto de intervenção, a partir de uma recolha de informação no terreno e do contacto com os diferentes atores do sistema. Os projetos em curso serão apresentados neste seminário.

Seminário | 29 Março, 12h00 | Avaliação da Fiabilidade em Estruturas de Betão Armado Reforçadas com FRP

 

Resumo

A fiabilidade estrutural considera o tratamento das incertezas que podem levar ao colapso de estruturas. A contribuição desta área na análise de estruturas existentes permite avaliar o risco inerente ao património edificado, incluindo em estruturas de betão armado, considerando: o património estrutural já edificado, que devido a vários fenómenos de envelhecimento apresenta tempos de vida úteis mais reduzidos ao inicialmente previstos; e cenários de reabilitação/reforço estrutural recorrendo ao uso de polímeros reforçados com fibras (FRP) por colagem externa, que devido às suas vantagens técnicas têm vindo a ganhar terreno nas últimas décadas.

Esta apresentação pretende abordar o tema da fiabilidade estrutural em estruturas de betão armado. Numa primeira parte, será feita uma breve introdução à fiabilidade estrutural. De seguida será feita uma abordagem de casos de estudo em estruturas de betão armado reforçadas com FRP.

Seminário | 15 Fevereiro, 14h30 | Ligas com Memória de Forma: Características e Aplicações

 

Resumo

As ligas com memória de forma são uma classe de materiais funcionais com enormes potencialidades de aplicações práticas pela conjugação de duas características particularmente relevantes: efeito de memória de forma e superelasticidade. Estes dois mecanismos, de natureza física distinta, possibilitam um vasto leque de aplicações quer por parte de cada um deles isoladamente, quer como resultado de actuação dos dois em conjunto. A cabal compreensão do desempenho destas potenciais aplicações necessita de estar suportada por uma correcta percepção dos parâmetros que afectam o efeito de memória de foma e a superelasticidade.
Esta apresentação compreenderá por isso, numa primeira parte, uma muito breve introdução aos princípios subjacentes às características funcionais (efeito de memória de forma e superelasticidade) desta classe de materiais e à sua caracterização. Segue-se uma abordagem das principais aplicações até agora abordadas em estudos levados a cabo no CENIMAT e a indicação das possíveis extrapolações para aplicações de interesse na área da indústria dos moldes.
