Transcription activator-like effectors (TALEs) are DNA-related proteins that recognise and bind specific target sequences to manipulate gene expression. Recently determined crystal structures show that their common architecture reveals a superhelical overall structure that may undergo drastic conformational changes. To establish a link between structure and dynamics in TALE proteins we have emp...

The degradation of reinforced concrete (RC) structural components owing to aging mechanisms and extreme loading events can cause significant performance safety concerns. Among the available alternatives for restoring such components, shape memory alloys (SMAs) exhibit unique properties, including recovery inelastic strain upon unloading (superelasticity) and/or heating (shape effect, SME). Part...

Martensitic transformation (MT), strain glass transition (SGT) and the corresponding stress-strain responses in cold-rolled Ti49.2Ni50.8 shape memory alloys (SMAs) at various amounts of cold-rolling deformation are investigated. A phase diagram describing all states transitions among them is established temperature – space. It shows a normal sharp, strong first-order B2 to B19? MT low levels (c...

Objective(s): NiTi is known as the most important material for manufacturing implants and medical devises duo to its shape memory and superelasticity properties, high energy damping, and high corrosion resistance. Methods: In this project, the possibility of producing nanostructured NiTi implant with high porosity was investigated. For reaching to the nan...

Shape memory alloys (SMAs) are types of materials that can restore their original shape upon severe or quasi-plastic deformation, being exposed to specific external stimuli, including heating, electric current, magnetic field, etc. They a category functional provides superelasticity as significant material property. The roots this unintentional discovery were in the 20th century, and later it a...
