Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

FEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...

Combined 5‐aminolevulinic acid and ferric ammonium citrate treatment promotes hair follicle growth by activating dermal papilla cells

FEBS Open Bio, EarlyView.
5‐Aminolevulinic acid combined with ferric ammonium citrate (5‐ALA/FAC) stimulates dermal papilla cell activity and promotes hair follicle growth. The treatment enhances ERK and AKT signaling, increases hair‐inductive gene expression, and restores dermal papilla function suppressed by dihydrotestosterone and oxidative stress, resulting in enhanced hair

Phase Formation Rules

2016
This chapter gives an overview of existing active phase formation rules for high-entropy alloys (HEAs). A parametric approach using physiochemical parameters including enthalpy of mixing, entropy of mixing, melting points, atomic size difference, and valence electron concentration is used to delineate phase formation rules for HEAs, with a reference to

Investigation on the Laves phase formation during laser cladding of IN718 alloy by CA-FE

, 2020
A deleterious Laves phase forms in the solidified structure of Inconel 718 (IN718) alloy during laser cladding, and the dynamic formation of Laves phase is difficult to be observed by experiments directly.

Factors determining solid solution phase formation and stability in CoCrFeNiX0.4 (X=Al, Nb, Ta) high entropy alloys fabricated by powder plasma arc additive manufacturing

, 2020
In high entropy alloys (HEAs), the formation of solid solution phase is governed by main factors such as mixing entropy, mixing enthalpy, atomic radii, and atomic size difference. However, factors such as electronegativity, valence electron concentration,

Galvanostatic phase formation

Journal of Solid State Electrochemistry, 2014
The results of a theoretical study on initial stages of electrodeposition under galvanostatic conditions are presented. The model of three-dimensional nucleation and growth under these conditions is developed. This model is used to calculate the times dependences of the overpotential, number of clusters formed on the electrode, and nucleation rate. The
