Crop residues reshape microbial community composition and function across acidic soils via interactions between carbon chemistry, soil pH and nutrient availability

Geoderma
There is a significant gap in understanding how crop residues with varying carbon-to-nitrogen (C/N) ratios mitigate soil acidification in acidic soils, particularly considering the complex interplay between soil C chemistry, pH, nutrient dynamics, and ...

Optimising CNT-FET biosensor design through modelling of biomolecular electrostatic gating and its application to β-lactamase detection

Nature Communications
Carbon nanotube field effect transistors (CNT-FET) hold great promise as next generation miniaturised biosensors. One bottleneck is modelling how proteins, with their distinctive electrostatic surfaces, interact with the CNT-FET to modulate conductance ...

The Metallo-β-lactamase GOB Is a Mono-Zn(II) Enzyme with a Novel Active Site [PDF]

, 2007
Metallo-β-lactamases (MβLs) are zinc-dependent enzymes able to hydrolyze and inactivate most β-lactam antibiotics. The large diversity of active site structures and metal content among MβLs from different sources has limited the design of a pan-MβL ...

Thermal Stability of Mixed Plasticizers, Residual Products of Forest Chemistry

Vestnik Tomskogo gosudarstvennogo arkhitekturno-stroitel'nogo universiteta. JOURNAL of Construction and Architecture
This work studies and analyzes qualitative indicators of commodity and non-commodity products of forest chemistry in order to recommend them for using as modifiers of technological and operational properties of bitumen binders. This is one of many potential areas for a beneficial use of forest chemical residues.
