Under physiological conditions, retinal pigment epithelium (RPE) is a cellular monolayer composed of mitotically quiescent cells. Tight junctions and adherens maintain the polarity RPE cells, are required for functions. In proliferative vitreoretinopathy (PVR), upon tear, cells lose cell-cell contact, undergo epithelial-mesenchymal transition (EMT), ultimately transform into myofibroblasts, leading to formation fibrocellular membranes on both surfaces detached retina posterior hyaloids,...

Abstract Achieving both interfacial stability and enhanced electrochemical performance in Ni‐rich layered oxide cathode (NCM811)‐Li batteries remains a critical challenge, especially at elevated temperatures. Current approaches, including artificial coatings fluorinated solvents, have improved but frequently fail to sustain long‐term due increased resistance or degradation over extended cycling. Here, an advanced electrolyte optimization strategy through the incorporation of triethyl...

The fatigue characteristics of the AZ91D-T6 alloy samples taken from engine blocks have been investigated at 20 °C and elevated temperature (150 °C). strength cyclic stress amplitude significantly decrease with increase test temperature, although hardening occurs continuously until failure for both temperatures. With decreased life tested same is mainly attributed to matrix increased hysteresis energies. Fatigue made controlled by casting defects. For defect-free specimens, crack initiation...

Abstract Aluminum‐lithium alloys are widely studied to improve performance in energetic materials. However, their high reactivity causes severe surface oxidation over micro‐Al particles storage, resulting significant deterioration the overall performance. This study deals with effect of iron coating on thermal properties and aging stability aluminum‐lithium alloy powder. Gas atomized Al‐3Li (3 wt. %) powder was prepared then successfully coated nano‐sized film by modified chemical liquid...

Mesenchymal stem cells (MSCs) may be easily isolated from the bone marrow, and possess multi-lineage differentiation potential various therapeutic applications. The of MSCs into osteoblasts is a complex process that regulated by multiple internal external factors. In present study, rabbit marrow using different osteoblast inductive media in presence dexamethasone, morphogenetic protein 2 (BMP-2), 1,25-dihydroxyvitamin D3, transforming growth factor β (TGFβ), platelet lysate cyclooxygenase...

Aluminum–magnesium alloy powders with magnesium contents ranging from 5% to 50 wt % were prepared by close-coupled gas atomization in order study the influence of magnesium-rich phase on oxidation powders. The composition, morphology, and process studied x-ray diffraction, scanning electron microscope/energy-dispersive x-ray, thermogravimetric/differential thermal analysis, respectively. results showed that complete temperature decreased increase content, selective occurred processes...

The nanocrystalline surface was produced on 3Cr13 martensite stainless steel using high‐current pulsed electron beam (HCPEB) technique. structures of the nanocrystallized were characterized by X‐ray diffraction and microscopy. Two nanostructures consisting fine austenite grains (50–150 nm) very carbides precipitates are formed in melted layer after multiple bombardments via dissolution crater eruption. It is demonstrated that formation supersaturated Fe (C) solid solution play a determining...

Abstract In this paper, the Aluminum−boron−europium ternary alloy fuels with boron content of 1.5∼4.85 wt. % and europium 3 were prepared by close‐coupled gas atomization.

High-current pulsed electron beam (HCPEB) technique is employed to irradiate the samples of polycrystalline pure nickel. The microstructures irradiated surface layers are investigated by using transmission microscopy (TEM). After HCPEB irradiation, very high value residual stress induced in layer, which leads formation dense dislocation walls and twins. Furthermore, a larger number vacancy defect clusters including loops, stacking fault tetrahedra (SFT) voids also formed. Among three...
