Engineering of CoA‐Acylating Butyraldehyde Dehydrogenase for Enhanced 1,3‐Butanediol Production in Escherichia coli

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Microbial production of 1,3‐butanediol (1,3‐BDO) offers a renewable route to this versatile C4 chemical. However, the low performance of CoA‐acylating butyraldehyde dehydrogenase (Bld), which contains a catalytic cysteine, limits efficient production in recombinant Escherichia coli (E. coli).

To freeze or not to: Quantum correlations under local decoherence

open access: yes, 2015
We provide necessary and sufficient conditions for freezing of quantum correlations as measured by quantum discord and quantum work deficit in the case of bipartite as well as multipartite states subjected to local noisy channels.

Dual‐Phase In Situ Symbiosis Structures for Ultrahigh Capacitive Energy Storage

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐phase in situ symbiosis structure designed by introducing a linear‐like pyrochlore phase (P phase) into the ferroelectric Aurivillius phase (A phase) and precisely controlling its proportion provides a new strategy for optimizing dielectric energy storage.

DFT Insight Into Physical Properties of Halide Ions Replacements in Oxo‐Selenate Halide Compounds for Photovoltaic Application

open access: yesEnergy Science &Engineering, EarlyView.
Using density functional theory (CASTEP, GGA–PBE), the structural, electronic, optical, and mechanical properties of YSeO₃X (X = F, Cl, Br, and I) compounds are systematically investigated. The materials have exhibited structural stability, tunable band gaps, strong optical absorption, anisotropic ductile behavior, and promising potential for ...

Origin of the anomalous piezoelectric response in wurtzite Sc$_x$Al$_{1-x}$N alloys

open access: yes, 2010
The origin of the anomalous, 400% increase of the piezoelectric coefficient in Sc$_x$Al$_{1-x}$N alloys is revealed. Quantum mechanical calculations show that the effect is intrinsic.
