MXenes as a Versatile Platform for High‐Energy‐Density Asymmetric Supercapacitors

open access: yesCarbon Energy, EarlyView.
MXenes with high conductivity and tunable surface chemistry are reviewed as advanced electrodes for asymmetric supercapacitors. MAX‐phase synthesis, surface and interlayer engineering, defect modulation, and composite designs are discussed, highlighting enhanced ion transport, pseudocapacitance, energy density, cycling stability, and sustainable routes

Infinite Functional Versatility, Formidable Limits: Evaluating Gallium‐Based Liquid Metals in Rechargeable Batteries

open access: yesCarbon Energy, EarlyView.
Beyond the hype surrounding the self‐healing properties of gallium‐based liquid metals (Ga‐LMs), this perspective critically examines their functional roles in metal‐ion batteries, highlighting both their underlying merits and the often‐overlooked challenges, including non‐representative design and testing configurations, performance overestimations ...

Fluorine‐Induced Selective Doping and Phase Transition Effect for FeNi Layered Double Hydroxides Towards Enhanced Oxygen Evolution Electrocatalysis

open access: yesCarbon Energy, EarlyView.
Fluorine‐induced partial phase transition from tetragonal to hexagonal FeNi layered double hydroxides (LDHs) markedly enhances their oxygen evolution reaction performance. F ions preferentially incorporate into the hexagonal lattice rather than the tetragonal phase, owing to the lower formation energy of F‐doped hexagonal structures.

Bismuth Chalcogenide‐Based Photocatalysts for Nitrogen Reduction: Recent Progress and Prospects

open access: yesChemistry – A European Journal, EarlyView.
Bismuth chalcogenides emerge as promising visible‐light photocatalysts for sustainable ammonia synthesis, driven by tunable electronic structures and strong N2 activation. Recent advances reveal how defects, doping and heterojunction design synergistically enhance charge separation and reactivity. Key challenges and future directions highlight pathways

Norethisterone contraceptive microspheres

Journal of Steroid Biochemistry, 1987
Two formulations of polylactic and polyglycolic acid microcapsules containing 75 and 100 mg of NET respectively were studied for a 90-day period of anticipated contraceptive effect in two groups of five women. A 200 mg dose of NET preparation was also studied for a 180-day period of anticipated contraceptive effect in 19 women.

Compartmentalization in proteinoid microspheres

Biosystems, 1977
Proteinoid microspheres with stable internal compartments and internal structure are made from acidic proteinoid and basic proteinoid with calcium. The populations of microspheres are characterized by a wide diversity of structure. A model of primitive intracellular communication is suggested by the observed movement of internal particles between ...
