Article Abstract
The fabrication of 3 x 3 crossbar arrays measuring 20 μm in width was demonstrated. The bipolar resistive switching characteristics in manganese oxide nanoparticles were investigated in the crossbar structure of top electrode (Au)/nanoparticle assembly/bottom electrode (Ti) on SiO2/Si substrate. The monodisperse manganese oxide nanoparticles measuring 13 nm in diameter were chemically synthesized by thermal decomposition of manganese acetate in the presence of oleic acid at high temperature. The nanoparticles were assembled as a layer measuring 30 nm thick by repeated dip-coating and annealing steps. The Au/nanoparticle assembly/Ti devices performed the bipolar behavior associated with the formation and sequential rupture of multiple conducting filaments in applying bias on Au electrode. When the voltage was swept from to +5 V to the Au top electrode, the reset voltage was observed at - 4.4 V. As the applied voltage swept from 0 to -5 V, the set voltage occurred at (-) -1.8 V.

In aquatic environments, bisphenol A (BPA) can undergo natural attenuation through microbial activity and manganese oxide-mediated processes. They commonly coexist, and that suggests the need to consider potential synergies between biotic and abiotic processes in BPA attenuation. This study explored BPA transformation in the coexistence of anaerobic microorganisms and β-MnO, with emphasis on the role of extracellular polymeric substances (EPS) commonly present in dissolved organic matter.

Sodium borohydride (NaBH) is considered as an outstanding hydrogen generation and storage material, whereas its widespread commercial application remains hindered by prohibitively high production cost and unsatisfied yield in the current production process. Electrochemical metaborate reduction reaction is a promising method to realize the low-cost and effective NaBH production, where the *H generation and the inhibition of HH coupling are critical but still remain challenging for suppressing competing hydrogen evolution reaction (HER). Herein, a core-shell structure with manganese oxide as a core and manganese single atom coordinated by nitrogen on the carbon substrate as a shell (MnO@Mn-N-C) was synthesized, where Mn-N-C enabled to boost water dissociation and electron donating as well as suppress HH coupling, thereby enhancing directed hydrogenation of reaction intermediate to generate NaBH.

Exposure of LIB materials to ambient conditions with some level of humidity, either accidentally owing to imperfect fabrication or cell damage, or deliberately due to battery opening operations for analytical or recycling purposes, is a rather common event. As far as humidity-induced damage is concerned, on the one hand the general chemistry is well known, but on the other hand, concrete structural details of these processes have received limited explicit attention. The present study contributes to this field with an investigation centered on the use of Raman spectroscopy for the assessment of structural modifications using common lithium iron phosphate (LFP) and nickel-cobalt-manganese/lithium-manganese oxide (NCM-LMO) cathodes.

Bamboo, as a rapidly renewable biomass material, has garnered significant attention in contemporary research due to its cost effectiveness as a viable source for supercapacitor electrode materials. However, untreated bamboo as an electrode material often leads to poor connectivity and uneven pore distribution. This study introduces a novel approach by using bamboo-derived biological carbon as a conductive substrate, subjecting it to carbonization through white-rot fungal pretreatment to enhance the pore structure and then loading it with nano-MnO sheets via a hydrothermal process.
