Ancient Egyptian Blue (CaCuSi4O10) Pigment by Modern Solution Combustion Synthesis Method

Eurasian Chemico-Technological Journal, 2016
The Egyptian blue pigment, CaCuSi4O10, has been used in ancient Egypt from 3000 BC. This pigment consists of CaCuSi4O10 with variable amounts of wollastonite (CaSiO3), high amount of Cu oxides, cuprite (Cu2O) or tenorite (CuO).

Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals

Angewandte Chemie, EarlyView.
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...

Boron Crosslinking Enables Anion‐Lean Solvation and Stable Interfaces for Dendrite‐Free Lithium Metal Batteries

Advanced Science, EarlyView.
The boron‐crosslinked gel polymer electrolyte (GPE_TMAB) enhances Li+ transport through Lewis‐acidic boron centers that selectively immobilize TFSI− anions, thereby enabling single‐ion conduction and promoting dendrite‐free lithium deposition. The engineered solvation structure drives the formation of an inorganic‐rich, mechanically robust SEI ...

Covalently Locked Donor–Acceptor Block Copolymer Nanoparticles Enable Efficient, Stable and Reproducible Photocatalytic Hydrogen Evolution

Advanced Energy Materials, EarlyView.
To overcome the efficiency–stability trade‐off of traditional donor:acceptor blends, covalently locked all‐conjugated block copolymer nanoparticles are developed for solar hydrogen production. This strategy achieves an outstanding HER rate exceeding 120 mmol cm−2 g−1 h−1, alongside exceptional operational stability (95% retention after 96 h) and high ...
