Miniaturized Low-Frequency Communication System Based on the Magnetoelectric Effect.

Recently, the realization of electromagnetic wave signal transmission and reception has been achieved through the utilization of the magnetoelectric effect, enabling the development of compact and portable low-frequency communication systems. In this paper, we present a miniaturized low-frequency communication system including a transmitter device and a receiver device, which operates at a frequency of 44.75 kHz, and the bandwidth is 1.

Geometry transformation of ionic surfactants and adsorption behavior on water/-decane-interface: calculation by molecular dynamics simulation and DFT study.

Understanding the effect of surfactant structure on their ability to modify interfacial properties is of great scientific and industrial interest. In this work, we have synthesized four amide based ionic surfactants under acidic or basic conditions, including CTHA·HCl, CTEA·HCl, CTHANa and CTEANa. Experiments have proved that the anionic surfactant with polyethylene oxide groups (CTEANa) had the lowest surface tension on the water/-decane interface.

Pyromellitic-Based Low Molecular Weight Gelators and Computational Studies of Intermolecular Interactions: A Potential Additive for Lubricant.

Low molecular weight gelators (LMWG) have been extensively explored in many research fields due to their unique reversible gel-sol transformation. Intermolecular interactions between LMWG are known as the main driving force for self-assembly. During this self-assembly process, individually analyzing the contribution difference between various intermolecular interactions is crucial to understand the gel properties.

Titanosilicate Derived SiO/TiO@C Nanosheets with Highly Distributed TiO Nanoparticles in SiO Matrix as Robust Lithium Ion Battery Anode.

Carbon-coated SiO/TiO (SiO/TiO@C) nanosheets consisting of TiO nanoparticles uniformly embedded in SiO matrix and a carbon-coating layer are fabricated by using acidified titanosilicate JDF-L1 nanosheets as template and precursor. SiO/TiO@C has unique structural features of sheetlike nanostructure, ultrafine TiO nanoparticles distributed in SiO matrix, and carbon coating, which can expedite ion diffusion and electron transfer and relieve volume expansion efficiently, and thus, the synergetic combination of these advantages significantly enhances its Li storage capability. As anode of lithium-ion batteries (LIBs), SiO/TiO@C nanosheets exhibit a high capacity of 998 mAh g at 100 mA g after 100 cycles.

Investigation of Y/SBA Composite Molecular Sieves Morphology Control and Catalytic Performance for n-Pentane Aromatization.

Using Y molecular sieve as the core, Y/SBA-15 composite molecular sieves were prepared by different crystallization methods in the paper. The growth process and morphologies of the composite molecular sieves were controlled by adjusting the synthesis factors. The structures and acidity of two kinds of composite molecular sieves were characterized by X-ray diffraction (XRD), N2 adsorption/desorption, transmission electron microscopy (TEM), and NH3-TPD.

Evaluation of three ornamental plants for phytoremediation of Pb-contamined soil.

Characteristics of accumulation and tolerance of lead (Pb) in Quamolit pennata, Antirrhinum majus L. and Celosia cristata pyramidalis were investigated to identify Pb-accumulating plants. In this study, pot culture experiment was conducted to assess whether these plants are Pb-hyperaccumulators or accumulators.

Adsorption and heterogeneous oxidation of As(III) on ferrihydrite.

Redox transformation of arsenic strongly influences its fate and transport in the environment. It is of interest to investigate heterogeneous oxidation of As(III) on the surface of major metal oxide in sediments. Whether As(III) can be oxidized on ferrihydrite and the role ferrihydrite plays as catalyst or oxidant are inconsistent in previous researches.

Photocatalytic oxidation of arsenite by a composite of titanium dioxide and activated carbon fiber.

Preoxidation process is usually needed in the treatment of arsenic-containing drinking water because arsenite (i.e. As[III]) is less easily removed by adsorption.
