In order to explore the deformation law of nanoindentation dislocation on different crystal planes of 6H-SiC by cube indenter at high temperature, the (0001), (11¯00) and (21¯1¯0) crystal planes were simulated by molecular dynamics, and changes of ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Deformation Mechanisms of FCC-Structured Metallic Nanocrystal with Incoherent Twin Boundary
Incoherent twin boundaries (ITBs) can significantly affect the mechanical properties of twin-structured metals. However, most previous studies have focused on the deformation mechanism of the coherent twin boundary (CTB), and metals with ITB-accommodated

Shockwave generates < 100 > dislocation loops in bcc iron
The formation mechanism of interstitial dislocation loops in ferritic steels stemming from irradiation remains elusive, as their formations are either too short for experiments, or too long for molecular dynamics simulations.

Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

Recurrent and radiographically unrecognized iatrogenic intra‐prosthesis hip dislocations
Hip dislocation is a common complication after total hip arthroplasty surgery. Newer prosthetic implants aim to reduce the risk of dislocation. The new dual mobility implant has a unique design that may result in intra‐prosthetic dislocation. We report a

Multiscale modeling of dislocation-precipitate interactions in Fe: From molecular dynamics to discrete dislocations. [PDF]
The stress-driven motion of dislocations in crystalline solids, and thus the ensuing plastic deformation process, is greatly influenced by the presence or absence of various pointlike defects such as precipitates or solute atoms.

Imeglimin attenuates liver fibrosis by inhibiting vesicular ATP release from hepatic stellate cells
Imeglimin, at clinically relevant concentrations, inhibits vesicular ATP accumulation and release from hepatic stellate cells, thereby attenuating purinergic signaling and reducing fibrogenic activation. This mechanism reveals a newly identified antifibrotic action of imeglimin beyond glycemic control.

Interactions between Dislocations and Penta-Twins in Metallic Nanocrystals
Dislocation interactions with twin boundary (TB) have been well-established in nanotwinned metals. Penta-twins, as an extreme of crystal twinning, are tacitly assumed to be more effective at blocking dislocation motions than conventional single or ...
