Pulvermetallurgische Funktionsbauteile aus NiTi- und NiTi-X Legierungspulvern [PDF]

, 2014
Powder metallurgy is an attractive option for manufacturing of NiTi parts considering its limited machinability due to the shape memory effect. Nevertheless, the industrial implementation of this process for NiTi-alloys is not trivial due to need of demonstrating reproducible shape memory behaviour which is strongly influenced by the high affinity for ...

Electronic Chip-Mimetic Medical Implants for Controllable Sonothermal Treatments. [PDF]

Adv Sci (Weinh)
Inspired by the thermal effect of working electronic chips, which consist of various heterostructures, an sonothermal‐responsive platform has been developed through constructing metal‐semiconductor interface on implants. Biofilm infection and deep vein thrombosis can be successfully treated by controllable ultrasound treatments.

Comparison of Two Partially Covered Metal Stents for Endoscopic Ultrasound-guided Hepaticogastrostomy: A Multi-Center Retrospective Study. [PDF]

DEN Open
ABSTRACT Objectives Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is an alternative biliary drainage method after failed endoscopic retrograde cholangiopancreatography. Nevertheless, it is associated with adverse events (AEs), including peritonitis and stent migration.

Structure and thermomechanics of selective laser melted nickel-titanium [PDF]

, 2015
NiTi has been established for applications in load-bearing implants due to its mechanical properties, which mimic the characteristics of bone better than any other known biocompatible metal or metallic alloy.

Uprighting Mandibular Third Molar Using NiTi Wire [PDF]

Dental 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

Известия 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

Processing of Porous NITI Preforms for NITI/MG Composites

Archives of Metallurgy and Materials, 2019
NiTi alloys are successfully used in engineering and medical applications because of their properties, such as shape memory effect, superelasticity or mechanical strength. A composite with Mg matrix, due to its vibration damping properties, can be characterized by low weight and good vibration damping properties.

La propuesta inmanentista de Amartya Sen para la justicia global

Isegoría, 2010
En The Idea of Justice (TIJ) de Amartya Sen se presenta una propuesta para comprender y defender la justicia global, alejada de las teorías de la justicia que se apoyan en el contrato social y en nociones institucionales trascendentales.

Shape memory compression anastomosis clips in gastrointestinal surgery in dogs

Veterinární Medicína, 2016
This paper describes clinical experiences with the use of shape memory nickel-titanium (NiTi) clips in gastrointestinal surgery in dogs. Side-to-side small bowel anastomosis was performed in eight dogs where intestinal continuity had to be restored after
