CeO -anchored β-Ni(OH) nanosheets onto nickel foam for efficient energy-saving hydrogen production an electrocatalytic glucose oxidation reaction.

Electrolytic glucose oxidation has garnered great interest in energy-saving hydrogen generation. However, high charge-transfer resistance and inefficient active centers have been recognized as the primary issues for poor electrochemical performance. In this study, for the first time, we offer a novel defect-rich CeO /β-Ni(OH) composite nanosheet-decorated Ni foam electrocatalyst (denoted as Ce@NF-GA), synthesized a unique hydrothermal approach under the co-participation of glycerol and acetic acid.

Validity evidence for a French version of the Stigma of Occupational Stress Scale for Doctors (SOSS-D).

Objectives: Physicians demonstrate low rates of help seeking for psychiatric disorders, occupational stress, and burnout due to perceived stigma. The Stigma of Occupational Stress Scale for Doctors (SOSS-D) is a brief standardized tool designed to measure stigma (personal, perceived other, and perceived structural) in physicians. The aim of this study was to gather validity evidence for a French version of the SOSS-D.

Facile synthesis of a 3D magnetic graphene oxide/FeO/banana peel-derived cellulose composite aerogel for the efficient removal of tetracycline.

Many initiatives have incorporated graphene oxide (GO) and biomass into aerogels for wastewater treatment. We report on the facile fabrication of a magnetic GO/FeO/banana peel-derived cellulose (bio-cellulose) aerogel using an ultrasound-assisted mechanical mixing method and freeze-drying technique for the removal of tetracycline (TC). The component materials and composite aerogel were characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), Raman spectroscopy, field-emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), nitrogen adsorption-desorption analysis, and vibrating sample magnetometry (VSM).

Biomechanics of phagocytosis of red blood cells by macrophages in the human spleen.

The clearance of senescent and altered red blood cells (RBCs) in the red pulp of the human spleen involves sequential processes of prefiltration, filtration, and postfiltration. While prior work has elucidated the mechanisms underlying the first two processes, biomechanical processes driving the postfiltration phagocytosis of RBCs retained at interendothelial slits (IES) are still poorly understood. We present here a unique computational model of macrophages to study the role of cell biomechanics in modulating the kinetics of phagocytosis of aged and diseased RBCs retained in the spleen.
