Considering that the silicon-on-insulator (SOI) devices have an inherent floating body effect, which may cause substantial influences in the performance of SOI device and circuit, we propose a novel device structure to suppress the floating body effect. In the new structure there is a buried p+ region under the n+ source and that region is extended to outside of the source, and this additional p+ region provides a path for accumulated holes to flow out of the body. Numerical simulations were carried out with Medici, and the output characteristics and gate characteristics were compared with those of conventional SOI counterparts. The simulated results show the suppression of floating body effect in the novel SOI device as expected.

The adsorption capability of bacterial cellulose（BC） for anionic dye acid fuchsine was studied. Meanwhile, the processes of the adsorption were investignted and fitted by adsorption isotherm models, adsorption thermodynamics and adsorption kinetics models, respectively. The changes of BC before and after adsorbing acid fuchsine were investigated via scanning electron microscopy（SEM） and Fourier transform infrared spectroscopy（FTIR） to further explain the adsorption mechanism. The results show that acid fuchsine could be effectively adsorbed by BC. The adsorption process was fitted well by Langmuir equation and the pseudo-second order kinetics, indicating that the adsorption process was monolayer molecule adsorption with the main action of chemical adsorption. The adsorption process was spontaneous and endothermic. Glucuronic acid groups and hydroxyl groups were responsible for the adsorption of acid fuchsine on BC.

Epstein-Barr virus(EBV),a double-stranded DNA virus with an envelope,is a ubiquitous pathogen that is prevalent in humans,although most people who contract it do not develop symptoms(Kerr,2019).While the primary cells EBV attacks are epithelial cells and B lymphocytes,its target range expands to a variety of cell types in immunodeficient *** change occurs in 90%of infected ***,immunoglobulin M(IgM)and IgG,serologically reactive to viral capsid antigens,are reliable biomarkers for the detection of acute and chronic EBV infections(Cohen,2000).Symptoms of EBV infection vary according to age and immune status.

Sodium-ion batteries have attracted considerable attention in the field of sustainable electrochemical energy storage, owing to their abundant resources and cost-effectiveness. However, their practical application is hindered by poor electrochemical performance under low-temperature(LT) environments. The kinetics of electrode reactions of cathode materials are notably hindered at LT, which makes the search for cathode materials with excellent LT performance a research hotspot. This review encapsulates the recent noteworthy progress in the application of cathode materials, including transition metal oxides, polyanionic compounds, Prussian blue and their analogs, in sodium-ion batteries operating at LT. It offers a comprehensive synthesis of diverse strategies employed to enhance their LT performance and engages in discussions regarding avenues for further enhancement. The overarching aim of this review is to furnish valuable insights and guidance for future research endeavors conducted at LT.

We report on the ability to create complex 3D flower-like SiO2 in vitro via CaCO3 micropar- icles supported by polyethyleneimine mediated biosilicification under experimentally altered chemical influences. The morphology, structure, composition of the product have been inves- tigated with the X-ray photoelectron spectrum, scanning electron microscope, transmission electron microscope, and energy-dispersive spectroscopy. Tile overall morphologies could be controlled to shift from a characteristic network of flower-like silica sphere to a sheet-like structure by adjusting physical adsorption of different amount of polyethyleneimine onto the surface of the CaCO3 microparticles.

Haff disease is a type of human rhabdomyolysis characterized by the sudden onset of unexplained muscular rigidity and an elevated serum creatine kinase level within 24 h after consuming cooked aquatic products. Here, we reviewed a previous study on Haff disease and summarized the clinical manifestations,epidemiological characteristics, and etiological data to confirm the incidence and global epidemiology of the disease and identify the most common seafood vectors. Future directions for Haff disease study will include further prospective etiological studies and the development of prevention and control strategies.
