Article Abstract
In this study, an efficient method for the separation of 5-hydroxymethylfurfural by the specific adsorption of dimethyl sulfoxide (DMSO) with cellulose microgels fabricated by electron beam irradiation was developed. The cellulose microgel was recovered and reused although this was accompanied by a decrease in the separation efficiency. A series of characterizations, including ultraviolet and infrared spectroscopy, scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and swelling ability tests, were performed to determine the adsorption behavior of the chemical structures of the microgel toward DMSO. The results showed that after the first run, the chemical structure of the recovered microgel did not change significantly. Electron-beam etching played a pivotal role in conferring a special capacity for enriching DMSO in its matrix on the microgel.

This Letter presents an investigation of low-energy electron-neutrino interactions in the Fermilab Booster Neutrino Beam by the MicroBooNE experiment, motivated by the excess of electron-neutrino-like events observed by the MiniBooNE experiment. This is the first measurement to use data from all five years of operation of the MicroBooNE experiment, corresponding to an exposure of 1.11×10^{21} protons on target, a 70% increase on past results.

In this study, silicon nanoparticles (NPs) were produced by pulsed laser ablation in a liquid, aiming to investigate the influence of a laser beam profile on the properties of the resultant NPs. Morphology, inner structure, and phase composition of the formed NPs were characterized by means of ultraviolet-visible spectroscopy, high-resolution transmission electron microscopy, and Raman and photoluminescence spectroscopies, and the correlation of the NP properties with the laser beam profile was studied. Three different beam profiles were selected, namely, a Bessel beam produced using an axicon, an annular profile formed using a combination of an axicon and a converging lens, and a Gaussian beam focused on the surface of a Si target using the same converging lens.

The well-known technique of microtomy, which is an essential cutting tool, was first developed for light and transmission electron microscope uses, but it is currently also utilized to prepare specimens for atomic force microscopy (AFM), ion microscopy using a focused ion beam (FIB), and scanning electron microscopy (SEM). Ultramicrotomy can only be used on soft substances and metals that are sufficiently ductile to be cut with a diamond knife. Before being sliced by a microtome, many soft materials must first go through numerous preparatory processes.

Background: Another approach to improve the dose conformity is to use charged particles like protons instead of the conventional X- and γ-rays. Protons exhibit a specific depth-dose distribution which allows to achieve a more targeted dose deposition and a significant sparing of healthy tissue behind the tumor. In particular, proton therapy has, therefore, become a routinely prescribed treatment for tumors located close to sensitive structures.

Background: Serum and other blood-derived products are widely used in biomedical and biopharmaceutical processes, especially for the production of vaccines or cell therapeutic applications. To ensure quality and safety, each serum lot undergoes testing for sterility to minimize the risk of disease transmission. A currently performed standard procedure is gamma-irradiation of serum for effectively killing pathogens.
