Electrical Potential of Acupuncture Points: Use of a Noncontact Scanning Kelvin Probe [PDF]

Evidence-Based Complementary and Alternative Medicine, 2012
Objective. Acupuncture points are reportedly distinguishable by their electrical properties. However, confounders arising from skin-to-electrode contact used in traditional electrodermal methods have contributed to controversies over this claim. The Scanning Kelvin Probe is a state-of-the-art device that measures electrical potential without actually ...

Grain-Boundary-Enriched Cocatalyst Coupled With CuSCN Hole Transport Layer for Efficient Solar Water Oxidation in BiVO₄ Photoanode. [PDF]

Adv Sci (Weinh)
A grain‐boundary‐enriched NiFe cocatalyst is coupled with a CuSCN hole transport layer on BiVO4 photoanodes. The integrated architecture promotes hole extraction, interfacial charge transfer, and surface OER kinetics, highlighting cocatalyst microstructure regulation as a complementary strategy to hole transport layer engineering. ABSTRACT Solar‐driven

Monolayer MoS₂ With Ultrahigh Piezoelectricity: From ALD Dose Control to Device Performance. [PDF]

Adv Sci (Weinh)
This study demonstrates that controlling precursor dosages in atomic layer deposition (ALD) serves to regulate ultrathin oxide quality, which in turn determines sulfurization behavior and MoS2 monolayer continuity. The resulting continuous, low‐defect monolayers enable improved piezoelectric performance and support a flexible slippage sensor, linking ...
