Article Abstract
Two interesting electronic transport properties including in-plane anisotropy and nonhomogeneous carrier distribution were observed in ReS nanoflakes. The electrical conductivity defined by the current parallel to the -axis (‖) is 32 times higher than that perpendicular to the -axis (⊥). Similar anisotropy was also observed in optoelectronic properties in which the ratio of responsivity ‖ to ⊥ reaches 20. In addition, conductivity and thermal activation energy with substantial thickness dependence were observed, which indicates a surface-dominant 2D transport in ReS nanoflakes. The presence of surface electron accumulation (SEA) in ReS has been confirmed by angle-resolved photoemission spectroscopy and scanning tunneling spectroscopy. The electron concentration (∼10 cm) at the surface is over three orders of magnitude higher than that of the bulks. Sulfur vacancies which are sensitive to air molecules are suggested to be the major factor resulting in SEA and high conductivity in ReS nanostructures.

This study develops an integrated X-ray absorption spectroscopy (XAS) photoemission electron microscopy (PEEM) platform on beamline BL09U at the Shanghai Synchrotron Radiation Facility (SSRF), enabling nanoscale characterization of complex materials through energy-resolved imaging and local-area XAS. By using the wide range of energy tunability, full access to different polarizations and PEEM's surface sensitivity, we have established a gap-monochromator control system under the EPICS framework to synchronize the elliptically polarized undulator (EPU) gap and monochromator energy dynamically, optimizing photon flux stability for absorption fine structure analysis. Combining X-ray magnetic circular dichroism (XMCD) and X-ray magnetic linear dichroism (XMLD) with PEEM and local-area XAS, this platform achieves concurrent mapping of electronic structures and magnetic domains in ferromagnetic nano-patterns, as demonstrated through our studies of NiFe Permalloy using this system.

Introduction: This study investigated the effect of sandblasting time and primer type on the shear bond strength of composite attachments to full-contour zirconia crowns.
Methods: A total of 108 zirconia specimens were fabricated and divided into 9 groups (n = 12) according to sandblasting time (10, 30, and 60 seconds) and primer type (silane, 10-methacryloyloxydecyl dihydrogen phosphate [MDP], universal). After sandblasting with 110-μm alumina particles, specimens were primed, and attachments were bonded using a packable composite.

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by persistent hyperglycemia with multiple clinical manifestations and complications, such as cardiovascular disease, kidney dysfunction, retinal impairment, and peripheral neuropathy. Continuous and minimally invasive glucose monitoring is essential for effective DM management. Microneedles (MNs)-based sensing platforms offer a promising solution; however, conventional polymeric MNs suffer from limited electrochemical sensitivity due to their insufficient electroactive surface area and inefficient loading of catalytic and enzymatic components.

Developing the efficient C─H bond activation carboxylation processes for furoic acid (FA) represents a critical technological challenge in achieving atom-economical synthesis of 2,5-furandicarboxylic acid (FDCA). Despite notable advancements in this field, the inherent contradiction between the high reactivity of furan rings and the chemical inertness of C─H bonds poses substantial technical bottleneck for achieving controllable C─H carboxylation under mild conditions. Herein, we report a high lattice-distorted MnOx catalyst with surface trench-like structures, wherein the Mn-O-conjugated configurations and electron-rich Mn cooperatively drive FA dehydrogenation and carbon radical reduction, inducing the free radical evolution process (FA→carbon-centered FA radical→FA carbanion), then coupled with solvent-polarized CO to accelerate the carboxylation process.
