Hybrid Nanostructured Porous Silicon-Silver Layers for Wideband Optical Absorption [PDF]

, 2019
As subwavelength nanostructures are receiving increasing attention for photonic and plasmonic applications, we grew nanostructured porous silicon (n-PS) and hybrid n-PS/Ag layers onto silicon substrates and measured their reflection and absorption ...

Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System

Advanced Materials, EarlyView.
A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

Effect of high temperature heat treatments on the quality factor of a large-grain superconducting radio-frequency niobium cavity [PDF]

, 2013
Large-grain Nb has become a viable alternative to fine-grain Nb for the fabrication of superconducting radio-frequency cavities. In this contribution we report the results from a heat treatment study of a large-grain 1.5 GHz single-cell cavity made of ...

Effect of thioglycolic acid and benzotriazole on the cathodic polarization potential during electrocrystallization of copper on copper single crystal planes [PDF]

, 1975
For thioglycolic acid (I) [68-​11-​1]​, (at concns. ≤10-​8M)​, the η (activation overpotential during Cu [7440-​50-​8] deposition) variation with time was the same at all c.ds. and the η values were lower as compared with the std.

Lattice Structures for Bone Replacement: The Intersection of Bone Biomechanics, Lattice Design, and Additive Manufacturing

Advanced Materials Technologies, EarlyView.
This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

Effects of Access Cavity Design on the Shaping Ability and Dentine Thickness Following Canal Preparation Using XP‐Endo Shaper or Reciproc

Australian Endodontic Journal, EarlyView.
ABSTRACT This study compared the shaping ability and remaining dentine thickness in mandibular molars prepared with traditional (TradAC) or ultraconservative (UltraAC) access cavities using Reciproc or XP‐endo Shaper instruments. Thirty‐two molars were scanned with micro‐CT before and after preparation to assess canal surface, volume, untouched walls ...

Perchloric Acid, an Effective Catalyst for Thermosetting Self‐Crosslinking Hydroxy Acrylic Resins

Journal of Applied Polymer Science, Volume 143, Issue 4, January 20, 2026.
Perchloric acid is an effective catalyst for the crosslinking of hydroxy acrylate resins. Its action is based on the intermediate formation of alkyl perchloric esters. Transesterification gives volatile alkyl perchlorates that evaporate to give a catalyst‐free resin.

Differential Scanning Calorimetric (DSC) Study of New and Sterilized Nickel-Titanium Rotary Endodontic Instruments [PDF]

, 2015
Introduction: Nickel-Titanium (NiTi) files have become popular in endodontic procedures compared to traditional stainless steel hand files owing to their increased flexibility which is especially advantageous in curved canals. Due to the associated costs,
