Refractory alloys without Cr, Al, and Si additions exhibit very poor high temperature oxidation resistance thus significantly limit their applications. With an aim to improve the of strong ductile refractory TiZrNbHfTa high‐entropy (HEAs), this study investigates effect Al on behavior mechanisms for 0‐1 HEAs. Higher content renders alloy more resistant oxidation. The AlTiZrNbHfTa exhibits a mass gain twice that conventional Ni‐based at 1100 °C 1 h, but much less than Nb because Al‐containing...
We report on 230 GHz (1.3 mm) VLBI observations of M87 with the Event Horizon Telescope using antennas Mauna Kea in Hawaii, Mt. Graham Arizona and Cedar Flat California. For first time, we have acquired interferometric phase information through measurement closure triangle long baselines. Most measured phases are consistent 0$^{\circ}$ as expected by physically-motivated models for structure such jet accretion disk models. The brightness temperature event-horizon-scale is $\sim 1 \times...
The oxide rupture-induced mechanisms that enable electrical conductivity of liquid metal nanoparticles using thermal and laser sintering.
It has long been known that solute segregation at crystalline defects can have profound effects on material properties. Nevertheless, quantifying the extent of nanoscale proven challenging due to experimental limitations. A combined and first-principles approach used study extended intermetallic phases ranging from 4 35 atomic layers in thickness. Chemical mapping by both atom probe tomography high-resolution scanning transmission electron microscopy demonstrates a markedly different...
Purpose: Describe aims, methods, characteristics of donors, donor corneas and recipients, potential impact the Diabetes Endothelial Keratoplasty Study (DEKS). Methods: The DEKS is a randomized, clinical trial to assess graft success endothelial cell density (ECD) 1 year after Descemet membrane keratoplasty (DMEK) using from donors with versus without diabetes in 1:2 minimization assignment. severity assessed by medical history, postmortem HbA1c, skin advanced glycation end-products oxidation...
Over the past ten years, corneal transplantation surgical techniques have undergone revolutionary changes1,2. Since its inception, traditional full thickness has been treatment to restore sight in those limited by disease. Some disadvantages this approach include a high degree of post-operative astigmatism, lack predictable refractive outcome, and disturbance ocular surface. The development Descemet's stripping endothelial keratoplasty (DSEK), transplanting only posterior stroma, membrane,...
