Shiravand, Fatemeh (Date of defense: 2014-06-03)
Cured epoxy resins are highly cross-linked polymers which are increasingly important in high performance engineering field due to the stiffness, high strength, heat resistance and solvent resistance. However one major ...
Elmansy, Reda Mohamed Yousyf Abdallah (Date of defense: 2023-01-19)
(English) This PhD mostly focuses in studding the flow around a square cylinder with an upstream splitter plate and considering different velocity ratios between the upper and lower inlet velocities. The PhD is based in ...
Majeed, Husam Tareq (Date of defense: 2018-10-05)
Aerobiology is the science that focuses on the study of the airborne living organisms (bacteria, fungal spores, pollen, small insects, etc.). The influence of meteorology and climate change on plant phenology include shifts ...
Wang, Lei (Date of defense: 2016-12-16)
In the current thesis, two TWIP steels with different chemical composition were successfully subjected to Severe Plastic Deformation with Equal Channel Angular Pressing (ECAP) at warm temperature (300°C), using a die with ...
Márquez Lobato, Yolanda (Date of defense: 2016-11-18)
Biomaterials based on block segmented copolymers constituted by hard and soft segments have attracted much attention for biomedical applications in the last decades, specifically as absorbable monofilament sutures. ...
Abt, Tobias (Date of defense: 2014-07-11)
The thesis at hand deals with the modification of cyclic butylene terephthalate (CBT) with the aim to improve its final properties. CBT polymerizes in an entropically-driven ring-opening polymerization into polymerized CBT ...
Mahboob, Amir (Date of defense: 2021-11-30)
Creating sustainability and public infrastructure is a fairly recent subject the engineering community has been debating. Introducing new building materials or introducing new structural designs is a strategy for constructing ...
Fraga Rivas, Iria (Date of defense: 2010-02-26)
Differential Scanning Calorimetry (DSC) is one of the most widely used thermal analysis techniques for the study of transitions and relaxation processes in polymers and also in other materials. It measures the heat flow ...
