A new generation of cryogenic processes for silicon deep etching

, 2007
International audienceDeep etching of silicon is intensively used in microtechnology for MEMS and power microelectronic components. At GREMI, we study and develop the cryoetching process, which is a good alternative in terms of rapidity and cleanliness ...

Soil-Landforms Interdependencies and Weathering at Admiralty Bay, King George Island, Maritime Antarctica

Quaestiones Geographicae
Soil formation in polar regions is relatively weakly recognised due to their rarity and spatial dispersion. The main pedological, sedimentological and cryogenic features of the ice-free coasts of Admiralty Bay were described and quantified with an ...

Ternary Crosslinking Builds Nanosheet Hard Carbon and Interfacial Polarization Regulates Na⁺ Kinetics in Hard Carbon Anodes

Carbon Energy, EarlyView.
Nanosheet Hard Carbon for Fast Na+ Storage ABSTRACT Hard‐carbon anodes for sodium‐ion batteries are often constrained by low initial Coulombic efficiency, severe interfacial polarization, and sluggish Na⁺ kinetics, especially when porosity engineering amplifies electrolyte consumption.

Concurrent effects of wafer temperature and oxygen fraction on cryogenic silicon etching with SF_{6}/O_{2}$ plasmas

, 2017
: Cryogenic plasma etching is a promising technique for high-control wafer development with limited plasma induced damage. Cryogenic wafer temperatures effectively reduce surface damage during etching, but the fundamental mechanism is not well understood.

Extraction of Antimicrobial Peptides From Fava Bean Protein Hydrolyzate by Phosphorylated Biochar

Food Safety and Health, EarlyView.
Antimicrobial peptides were extracted by functional biochar in one step. The enriched peptides demonstrated significantly enhanced antibacterial activity. ABSTRACT The extraction of antimicrobial peptides (AMPs) from plant proteins remains challenging due to their low abundance, structural diversity, and the need for mild, efficient, and selective ...
