Article Abstract
An electron optic system (EOS) consisting of a sheet electron beam gun (SEB) and a pole offset periodic cusped magnet (PO-PCM) is reported for 340-GHz frequency. A sheet electron beam with a voltage of 29 kV, beam compression ratio of 16, and a beam waist of size 0.17 mm × 0.044 mm was designed and optimized using computer simulation technology (CST). The EOS was capable of transmitting the beam with a current of 6.9 mA through a beam tunnel of size 0.516 mm × 0.091 mm, having a length of 60 mm with the help of a pole offset periodic cusped magnet. The axial magnetic field generated by the PCM was 0.32 T. The EOS was efficient enough to transmit the beam stably through the beam tunnel with a transmission rate of 100%.

Although antimicrobial peptides possess potent antimicrobial activities, the high cost of production, based on amino acid length, has limited their therapeutic and cosmeceutical applications. This study aimed to produce and characterize de novo designed antimicrobial peptides derived from WSKK11 and WSRR11 for efficacy against acne-causing bacteria. Ten designed peptides were evaluated for antimicrobial, hemolytic, and cytotoxic activities, as well as, secondary structures by FTIR and modes of action.

In this work, we report a facile strategy for synthesizing hydrophilic Gd(OH) sheets via a Gd-based interfacial precipitation reaction at the interface of organosilane-modified GdO nanoparticles and a cation exchange resin. This strategy, independent of the specific organosilane used, produces two-dimensional sheets with a distinct lamellar structure and excellent aqueous dispersibility. Characterization confirms the formation of Gd(OH) sheets with promising fluorescent and magnetic properties.

This study investigates how hydrophobic and hydrophilic modifications at the C-terminus of the base peptide, KFEFEFKFK (KbpK), affect the hydrogel macroscopic properties. By the incorporation of phenylalanine (F, hydrophobic) and lysine (K, hydrophilic) residues, four variants, KbpK-K, KbpK-F, KbpK-KF, and KbpK-FK, were designed and evaluated. pH-concentration phase diagrams and Fourier transform infrared confirmed clear links showing how peptide hydrophobicity and charge influence β-sheet formation and macroscopic phase behavior.

With the rapid development of the nuclear medicine business worldwide, the removal of iodine-131 from specific contaminated environments to protect public health has important application prospects. In this study, the surface decontamination mechanism of Ce(IV)/HNO3 as a decontaminant for iodine-131-contaminated nonmetallic materials was investigated by using an orthogonal experimental method and scanning electron microscopy (SEM). During the preparation experiments with the contaminated materials, both quartz glass and ceramics reached peak activity concentration levels at 4 h of adsorption (contamination) by using immersion; the decontamination factor (DF) was selected as the test index for the decontamination experiments.

The design of carbon allotropes that simultaneously exhibit mechanical robustness and quantum functionalities remains a longstanding challenge. Here, we report a comprehensive first-principles study of cT16, a three-dimensional sp-hybridized carbon network with topologically interlinked graphene-like sheets. The structure features high ideal tensile and shear strengths, with pronounced anisotropy arising from strain-induced bond rehybridization and interlayer slipping mechanisms.
