Summary: The use and storage of renewable and clean energy has become an important trend due to resource depletion, environmental pollution, and the rising price of refined fossil fuels. Non-lithium-ion batteries have attracted attention as a new focus for energy storage due to the limited resource and uneven distribution of lithium. This review discusses the theoretical progress of 2D SMR inorganic materials in the field of non-lithium-ion batteries, summarizing the common relationship among 2D SMR non-lithium energy storage anodes.

Summary: Appropriate condition monitoring methods can evaluate the status of power semiconductor devices in time, and acoustic emission detection technology is a supplement to conventional methods. However, the source mechanism of the stress waves generated during device switching has not been identified, hindering the further application of acoustic emission detection technology. This article proposes new theoretical models to explain the stress wave generation during turn-OFF and validates the models through formula derivations, simulations, and experiments.

Summary: In this paper, a novel hybrid material, histaminium bis(trioxonitrate) (HTN), was presented. The crystal structure of HTN was determined by single-crystal X-ray diffraction, showing that it adopts a monoclinic system with space group P2(1)/c. The compound's atomic structure was modeled as a three-dimensional network, with organic cations and nitrate anions connected via N-H...O and C-H...O hydrogen bonds. The compound's properties and interactions were analyzed using various spectroscopic and computational techniques.

Summary: Complex material surfaces can effectively reduce secondary electron emission (SEE) and sputtering through geometric trapping. This study characterized the SEE yields of open-cell reticulated carbon foam with various geometries using scanning electron microscopy. The results show a total reduction in SEE yield of 23.5%-35.0% for carbon foams with 3% volume fill density and 10-100 pores per inch (PPI). The transparency of the foam backplate is identified as a critical parameter, influencing the primary electron angular dependence on SEE yield.

Summary: In this study, a tunable luminescence color from yellow to orange was achieved in BaGa2O4: Bi3+ phosphors with the introduction of Sr2+ ions, which also enhanced the optical storage capacity behavior. The results demonstrate the dependence of luminescence performance on the crystal sites of Bi3+ ions, paving the way for the design of Bi3+-doped solid solutions for optical storage applications.

Summary: Two series of 2,5-di(butoxy)phenyleneethynylenes, one halogenated (nPEC4-X; n=2, 3, or 4) and the other boron-dipyrromethene (BODIPY) terminated (nPEC4-By; n=3, 4, or 5; By=BODIPY), were synthesized and characterized using NMR spectroscopy and mass spectrometry. The study found that the phenyl in the meso position of BODIPY becomes electronically part of the conjugation of the phenyleneethynylene chain, while BODIPY itself is electronically isolated. Energy transfer from phenyleneethynylene chain to BODIPY decreases with the increase in distance between the two chromophores, resulting in dual emission for the longest oligomer where energy transfer is quenched.

Summary: Charge transport via interfaces is crucial for understanding the limitations of electronic devices. This study investigates the electronic properties of heterostructures formed by semiconductors with zinc-blende unit cells in contact. It examines the changes in band-gap values and potential energy at the interface region. The primary conclusion is that the electrostatic potential of the system determines the unique properties of the heterostructure, and the transmission coefficient of the electronic wave function at the interface can be predicted by examining the material's potential parameters.

Summary: This study investigates the structural, electronic, and optical properties of iodinene using density functional theory and first-principles calculations. Iodinene is predicted to be an intrinsic semiconductor, and the electronic bandgap decreases with increasing atomic layers. The absorption spectra of iodinene show a blue shift as the number of layers increases.

Summary: We have demonstrated the out-of-focus ultrafast pulsed laser processing of copper with a variable working distance, without mechanical movement, by using a diffractive optical element. The method has been practically applied to reduce the secondary electron yield (SEY) of copper to below 1.3. Using an extended focus element not only increases the consistency of processing across different working distances, but also changes the topography of the produced structures, reducing the SEY. This approach shows promise in preventing electron clouds in the upcoming high luminosity upgrade of the Large Hadron Collider (LHC).

Summary: Stimulated emission depletion nanoscopy (STED) is a technique used to study the ultra-structures of organelles in live cells by surpassing the optical diffraction limit. However, powerful laser illuminations cause phototoxicity and photo bleaching, leading to the need for probes with superior photophysical properties. This study explores the factors influencing the performance of STED probes through theoretical calculations, focusing on the chemical structure of the dyes.

Summary: This study investigated the electron inelastic mean free path (IMFP) and elastic mean free path (EMFP) in graphene using an improved approximation within a classical electron trajectory framework. A unique hump feature was observed in the IMFP results of multilayer graphene, attributed to the out-of-plane mode of the pi + sigma plasmon, while it was absent in monolayer graphene. The obtained EMFPs were found to be one order of magnitude higher than previously reported results.

Summary: The study focuses on the SEM characterization of a smoothly varying nanograting structure prepared by laser-focused atomic deposition, highlighting the challenges in quantitatively characterizing the structural features of the grating lines. By using MC simulation methods, the unknown geometrical parameters of the grating lines, such as base height, peak height, linewidth shrinkage, and peak tilt angle, were successfully extracted from experimental linescan profiles of SEM images, extending the CD characterization to more complex structures.

Summary: This work investigates the detailed difference between dielectric function models, the Mermin model and the full Penn algorithm (FPA) model, for the determination of an electron inelastic mean free path (IMFP) with optical energy loss function (ELF). The differences of IMFPs calculated by the two models are material dependent and significant in the low energy region.
