Exploitation of transition temperatures of NiTi- SMA by adjusting SLM parameters

open access: yesCurrent Directions in Biomedical Engineering, 2021
It is well known that the transition temperatures, e.g. the austenite peak temperature Ap, of NiTi Shape Memory Alloys (SMAs) can be adjusted by changing the alloy composition.

Uprighting Mandibular Third Molar Using NiTi Wire [PDF]

open access: yesDental Journal of Advance Studies
If impacted teeth can be brought into occlusion, they should be brought into occlusion, especially in young patients. When the second molar is missing, saving the third molar becomes all the more important.

A Methodology to Design Broadband Negative Inductors with Tight Tolerance for Microwave Applications

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2023
Introduction. Non-Foster elements (NFEs) mimic behavior of hypothetical negative inductors or capacitors in a certain frequency band. NFEs are used to compensate reactance of conventional inductors and capacitors that allows designing broadband microwave
