Gas–liquid mass transfer enhancement in the presence of nanoparticles under slug flow in microreactors

AIChE Journal, EarlyView.
Abstract Nanofluids containing nanoparticles represent a promising solvent or reaction system for gas–liquid operations. Herein, the effect of nanoparticle (Al2O3 and SiO2) addition on gas–liquid slug flow pattern and mass transfer enhancement was investigated during CO2 absorption into water in microreactors.

Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

Advanced NanoBiomed Research, EarlyView.
Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...

Nacre‐inspired layered composite with excellent mechanical support and osteogenic potential for cervical interbody cage

BMEMat, EarlyView.
The cervical interbody cage needs to take both biomechanical and biological requirements into account. Here, a new‐style degradable, multicomponent, and bioinspired nacre‐like cervical interbody cage composite, which exhibits promising mechanical‐support‐related behavior and osteogenesis‐related potential, is designed and prepared.

Pressure‐Enhanced CO2‐to‐CO Electroreduction on Ag‐Based Catalysts: Industrially Relevant Rates and Mechanistic Insights

Carbon Energy, EarlyView.
Ag‐based catalysts operated under elevated CO2 pressures exhibit markedly enhanced intrinsic activity for CO formation, with OD‐Ag achieving −200 mA cm–2 and 90% FECO at −1.3 VRHE. Mechanistic analysis shows that high pressure strengthens a *COOH‐mediated pathway by increasing intermediate coverage and suppressing hydrogen evolution, establishing CO2 ...

Peek (Polyether Ether Ketone) – A Review Article

Indian Journal of Forensic Medicine & Toxicology, 2020
This article is aimed to review the applications of Polyether Ether Ketone (PEEK) in dentistry. The evolving desire for functions and aesthetics, few drawbacks with existing materials and clinicians shifting their paradigms towards metal free restorations led space for the metal-free restorations in today’s restorative practice.

Highly Conductive Networks Encapsulated Borohydride Electrolytes Enabling Superior High Rate Performance for All‐Solid‐State Li‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanoscale ZrB2/LiCl network encapsulated LiBH4 solid electrolyte was prepared by mechanically reacting LiBH4 with ZrCl4. Such a composite solid electrolyte exhibits fast ionic conduction and high critical current density. More importantly, the resultant solid electrolyte enables unprecedented cyclability of Li|LiNbO3@LiCoO2 and Li|TiS2 full cells at ...
