Comparison of Different Temperatures on Bending Properties of Six Niti Endodontic File Systems [PDF]

, 2018
Introduction: Manufacturers claim that modern NiTi files with proprietary heat treatment transform at higher temperatures, thus staying more martensite and being more resistant to cyclic fatigue and more flexible.

Endoscopic Ultrasound‐Guided Hepaticogastrostomy With Plastic Stents in Comparison to Transpapillary Drainage With Metallic Stents for Unresectable Malignant Distal Biliary Obstructions

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is usually performed for unresectable malignant distal biliary obstruction (MDBO) when endoscopic retrograde cholangiopancreatography‐guided biliary stenting with fully covered self‐expandable metallic stents (EBS‐MSs) fails.

RF‐Shielding of Laser‐Cut Venous Stents: Calculations, Simulations, and Experiments

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2331-2344, April 2026.
ABSTRACT Purpose To develop an analytical model of the RF‐shielding of laser‐cut venous stents for different orientations and stent geometries. Methods Laser‐cut venous stents are modeled as a grid composed of circular and rectangular loops. As these loops are orthogonal they shield different components of the transmit RF field.

Investigating the Effects of Build Height on Mechanical Behavior of Large‐Scale Laser Wire Directed Energy Deposited Nickel Titanium Alloy

Advanced Engineering Materials, Volume 28, Issue 3, 4 February 2026.
Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...

Impact of Various Sleeve Materials on Temperature Variations During Guided Endodontic Access Cavity Preparation Utilizing Finite‐Element Analysis

Clinical and Experimental Dental Research, Volume 12, Issue 1, February 2026.
ABSTRACT Purpose Guided endodontics allows precise access in challenging cases such as calcified canals; however, drilling can generate temperature increases that risk damaging periradicular tissues. This study aimed to evaluate the influence of different sleeve materials—zirconia, cobalt‐chromium (CoCr), and titanium—on temperature changes during ...

Grain refinement of NiTi alloys during ultrasound-assisted wire-arc directed energy deposition

Virtual and Physical Prototyping
Achieving grain refinement in the wire-arc directed energy deposition (DED) process of NiTi alloy is highly challenging. We have successfully obtained NiTi alloy with a fine microstructure and observed an improvement in superelastic recoverability by ...

Emerging Triboelectric Nanogenerators for In‐Body Implantation

Small Methods, Volume 10, Issue 3, 9 February 2026.
This review explores functional implantable triboelectric nanogenerators in biomedical applications, discussing their mechanisms, electricity generation, and design approaches. To solve postimplantation challenges, four types of triboelectric nanogenerators (TENGs) are introduced: stretchable, bioadhesive, on‐demand biodegradable, and multiresponsive ...
