Dynamic Motions of Topological Defects in Nematic Liquid Crystals under Spatial Confinement

Description: Article discusses how topological defects (TDs) have become a sensational topic due to their significant influence on the unusual optical and physiochemical characteristics of the material. Here, authors assert how nematic liquid crystals confined in a cell exhibiting surfaces with periodic anchoring conditions containing surface topography are relied on.

Effect of Cu and Ni Inclusion on Tribological Performance of Tribocatalytically Active Coatings in Hydrocarbon Environments

Description: Article describes how protective coatings are important for enhancing tribological behavior, preventing surface degradation, and reducing friction-induced energy losses during the operation of mechanical systems. The authors study the effect of catalytic metals, specifically their compositions and amount, on the tribocatalysis process.

Evolution of microstructure and mechanical properties in gas tungsten arc welded dual-phase Fe50Mn30Co10Cr10 high entropy alloy

Description: Article describes how in recent years, high entropy alloys (HEAs) have been shown to be promising alternatives to common engineering alloys, depending on their composition and thermomechanical processing. In the present work, Gas Tungsten Arc Welding (GTAW) was used to achieve defect-free joints based on a novel transformation induced plasticity (TRIP) Fe50Mn30Co10Cr10 HEA.

Role of heterophase interfaces on local coercivity mechanisms in the magnetic Al0.3CoFeNi complex concentrated alloy

Description: Article describes how authors use state-of-the-art electron microscopy techniques to show that the magnetization reversal process in an Al0.3CoFeNi magnetic complex concentrated alloy (CCA), which is responsible for its coercivity, changes dramatically from a nucleation-type mechanism in the FCC+L12 state of the CCA. Their work reveals that heterophase FCC/BCC interfaces have a much stronger effect on coercivity than isostructural chemically ordered/disordered interfaces and provides a powerful… more

Structure and Electronic Properties of InSb Nanowires Grown in Flexible Polycarbonate Membranes

Description: The article explores the various factors that affect nucleation and nanowire growth. A dense array of vertically aligned indium antimonide (InSb) nanowires with high aspect ratio were grown in the pores of a track-etched polycarbonate membrane via a one-step electrochemical method.
