Simulation of Cross Wedge Rolling and Hot Extrusion-Combined Forming Process for Axle Sleeve

, 2023
In this paper, an axle sleeve is formed through a combined cross wedge rolling (CWR) and hot extrusion process, and the combined forming process is simulated via finite element analysis software Deform-3D.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Simultaneous enhancement of oxidation resistance in Nb-Si based alloys at 1250 °C by GdNbTiO6 formation and microstructural refinement

Applied Surface Science Advances
The oxidation resistance and behavior of Nb-16Si-20Ti-1.5Zr-1B-1C-xGd (x = 0.05, 0.1, 0.2, 0.4 at.%) alloys at 1250 °C were investigated. A suitable Gd addition (0.2 at.%) effectively refines the microstructure. Oxidation tests reveal that the alloy with

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Microstructural evolution and oxidation resistance at 1250 °C of a slurry-sintered Si–Cr–Mo–Ti multicomponent silicide coating on a high-Al Nb–Si-based alloy

Applied Surface Science Advances
A Si–Cr–Mo–Ti coating was fabricated on a Nb–22Ti–15Si–3Cr–10Al–0.3Y (at.%) substrate by slurry sintering, and its initial microstructural characteristics and oxidation behavior at 1250 °C were systematically investigated.

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses
