Microstructure-based model for the stress-strain relationship of hot-rolled dual-phase steel

工程科学学报, 2015
The microstructure of hot-rolled dual-phase steel was studied by scanning electron microscopy(SEM) and transmission electron microscopy(TEM). The volume fraction of each phase in the dual-phase steel was determined by Image-Pro Plus software.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Flux-Weakening Strategies for a Five-Phase PM Synchronous Machine [PDF]

, 2011
In order to get a low cost mild hybrid system, a global objective is to keep the actual thermal engine architecture. As consequence, the current clawpole synchronous automotive generator must be replaced by a new more powerful electrical machine but with

Design and characterization of SiC varactor-based phase shifters [PDF]

, 2012
Design and realization of two continuously tunable phase shifters for 1.4 GHz band is presented. Both circuits are based on SiC varactors, conceived to enable high-voltage, high-power operation, and suitable for application in the transmitter chain of ...

Deformation behavior of designed dual-phase CuZr metallic glasses

Materials & Design, 2019
A nanometer-scale second phase in metallic glass (MG) heterostructures is effective to improve mechanical properties. In this work, molecular dynamics simulations are conducted to investigate the influence of various critical structural aspects such as ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Dual-Phase Liquid Xenon Detectors for Dark Matter Searches [PDF]

, 2014
Dual-phase time projection chambers (TPCs) filled with the liquid noble gas xenon (LXe) are currently the most sensitive detectors searching for interactions of WIMP dark matter in a laboratory-based experiment.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

In situ atomic-scale study on the ultralarge bending behaviors of TiO2-B/Anatase dual-Phase nanowires

, 2019
It is challenging but important to understand the mechanical properties of one-dimensional (1D) nanomaterials for their design and integration into nanodevices. Generally, brittle ceramic nanowires (NWs) cannot withstand a large bending strain.
