Scalable catalyst production process for oleate hydratase whole‐cell biocatalysis

Biotechnology Progress, EarlyView.
This study establishes a scalable lactose‐induced fed‐batch fermentation for an Escherichia coli whole‐cell biocatalyst containing an oleate hydratase. Operation at a higher growth rate markedly increased biomass yields while maintaining catalyst activity and was demonstrated at 150 L scale.

Engineering Mechanically Adaptive Nanonetworks for Long‐Life and High‐Capacity Silicon Anode Batteries

Carbon Energy, EarlyView.
ABSTRACT Silicon anodes, with a theoretical capacity of ~ $\unicode{x0007E}$3860 mAh g−1, offer more than ten times the lithium storage of graphite but suffer from large volume expansion during lithiation, leading to particle fracture, electrical disconnection, and unstable solid–electrolyte interphases (SEIs).

Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process

Carbon Energy, EarlyView.
Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

Resource‐Efficient Electrodes with Metallized Woven‐Glass‐Grid Current Collectors for Lithium‐Ion Batteries

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The use of metallized glass‐based woven‐grids instead of metal foils as current collectors for LIBs leads to a significant reduction in metal usage by over 90 % and weight savings of more than 80 %, resulting in an 11 % increase in specific energy at the cell level. Abstract A novel class of resource‐efficient, woven‐glass‐grid current collectors (CCs)

Spatiotemporal cellular dynamics of the notochord shape intervertebral disc morphogenesis in the mouse embryo through apoptosis and proliferation

Developmental Dynamics, EarlyView.
Abstract Background The notochord is a midline structure essential for vertebrate embryogenesis, contributing to the development of the nervous system, digestive tract, and vertebral column. In particular, notochord signaling is indispensable for proper patterning and coordinated development of alternating vertebrae and intervertebral discs (IVDs ...

Drosophila male genitalia rotation depends on permissive remodeling of the posterior abdomen

Developmental Dynamics, EarlyView.
Abstract Background One of the most characteristic morphogenetic processes in Drosophila is the 360° rotation of the male pupal genital disc. This movement is driven by the myosin Myo1D, whose expression in the genital disc is controlled by the Hox gene Abdominal‐B (Abd‐B).

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Bending-torsion coupling vibrations of dual-disk rotor system with imbalance and oil film bearings

Advances in Mechanical Engineering
Due to the errors of manufacturing and installation of the rotor system, there is a certain deviation between the centroid and the geometric center of the rotor, known as eccentricity, which causes the bending and torsional vibrations during operation ...
