Two‐Dimensional Polymers as Modular Metal‐Free Solid‐State Catalysts for Efficient Sono‐Piezo‐Photocatalytic Hydrogen Peroxide Production

open access: yesAngewandte Chemie International Edition, EarlyView.
This study demonstrates the high piezo‐photocatalytic activity of solid molecular catalysts (SMCs) in the production of hydrogen peroxide from water and oxygen. Through the rational design of molecular motifs (diphenylpyridine or terpyridine) and backbone functionalities (methyl group, aliphatic amine antenna, or aromatic pyrrole unit), as well as ...

Rational Formulation of Ether‐Lactone Electrolytes for Safe and Sustainable Ni‐Rich Lithium‐Ion Batteries

open access: yesAngewandte Chemie International Edition, EarlyView.
This study reports the formulation of innovative electrolytes to improve safety, sustainability, and compatibility with Ni‐rich cathodes through the use of a bio‐based solvent (γ‐valerolactone, GVL) and a safe, stable, innovative co‐solvent (diethylene glycol butyl ethyl ether, DEGBEE).

A fundamental approach to adhesion: Synthesis, surface analysis, thermodynamics and mechanics [PDF]

open access: yes
The effects of composites as adherends was studied. Several other variables were studied by fractography: aluminum powder adhesive filler, fiber glass cloth scrim or adhesive carrier, new adhesives PPQ-413 and LARC-13, and strength-test temperature. When

Asymmetric Fe–Te Pairs Enhance Peroxymonosulfate Activation via Surface‐Bound Hydroxyl Radicals Pathways

open access: yesAngewandte Chemie International Edition, EarlyView.
An asymmetric Fe–Te dual‐atom pair directs peroxymonosulfate activation toward long‐lived surface‐bound hydroxyl radicals through strong p–d hybridization. The resulting electronic asymmetry enables efficient pharmaceutical degradation and reveals a metal–metalloid pairing strategy for steering reactive oxygen species pathways in advanced oxidation ...

Graphite intercalation compound with iodine as the major intercalant [PDF]

open access: yes
Halogenated CBr(sub x)I(sub y) (1 less than y/x less than 10) was made by exposing graphite materials with interplanar spacing in the 3.35 to 3.41 A range to either pure Br2 or an I2-Br2 mixture, and then to iodine vapor containing a small amount of Br2.

Selected fretting-wear-resistant coatings for titanium - 6-percent-aluminum - 4-percent-vanadium alloy [PDF]

open access: yes
A titanium - 6-percent-aluminum - 4-percent-vanadium alloy (Ti-6Al-4V) was subjected to fretting-wear exposures against uncoated Ti-6Al-4V as a baseline and against various coatings and surface treatments applied to Ti-6Al-4V.

Eco‐Friendly Aqueous Polymeric Binders for High‐Performance Graphite Anodes: Structure–Property Insights for Lithium‐Ion Batteries

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Polyvinylidene fluoride (PVdF) is commonly used as a binder material in the preparation of anode or cathode electrode slurries for commercial Li‐ion batteries (LIBs). High‐cost PVdF binder generally requires the use of toxic and environmentally unfriendly N‐methyl‐2‐pyrrolidone (NMP) as a solvent for dissolution.

Dynamics of solid lubrication as observed by optical microscopy [PDF]

open access: yes
A bench metallograph was converted into a micro contact imager by the addition of a tribometer employing a steel ball in sliding contact with a glass disk. The sliding contact was viewed in real time by means of projection microscope optics. The dynamics
