Microstructural and morphological properties of homoepitaxial (001)ZnTe layers investigated by x-ray diffuse scattering

open access: yes, 2005
The microstructural and morphological properties of homoepitaxial (001)ZnTe layers are investigated by x-ray diffuse scattering. High resolution reciprocal space maps recorded close to the ZnTe (004) Bragg peak show different diffuse scattering features.

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

A study of the mechanisms of the semi-insulating conversion of InP by anelastic spectroscopy

open access: yes, 1999
Elastic energy absorption measurements versus temperature on semiconducting, semi-insulating (SI) and Fe-doped InP are reported. A thermally activated relaxation process is found only in the SI state, which is identified with the hopping of H atoms ...

Breeding cold‐tolerant Orius laevigatus lines improves thermal tolerance and body size: implications for biological control

open access: yesPest Management Science, EarlyView.
Biological control agents performance is influenced by temperature. Two cold‐tolerant lines of O. loevigatus were developed, improving their fitness at both low and high temperatures, offering advantages far augmentative biological control. Abstract BACKGROUND The performance of biological control agents (BCAs) is strongly influenced by environmental ...

Additives for Aluminum‐Air Batteries: A Review

open access: yesSmall, EarlyView.
The role of electrolyte additives in Al–air batteries is investigated by focusing on their capacity to moderate Al corrosion rates, inhibit self‐discharge, and prevent surface barrier formation. Additives present in organic, inorganic, and hybrid categories, which regulate the Al–electrolyte interface by forming protective films on the Al surface ...
