Summary: ZnO particles were synthesized and their free radical scavenging activity properties were evaluated in this study. The results showed that the scavenging activity increased with smaller particle size and lower ZnO dosage. A pseudo-first-order kinetics model may be present in the reaction.

Summary: The debate on hazards associated with sub-micron sized plastics is limited by a lack of quantitative data on their uptake and biological fate in organisms. Analytical methods should be developed to identify and quantify sub-micron particulate plastic in biota to understand their biodistribution, localization, bioaccumulation, and clearance. These methods are expected to be transferable to studies considering sub-micron plastics in various aspects like food, consumer products, human health, and the environment.

Summary: Dynamic molecular interactions in chemical reaction networks lead to complex behaviors in living systems. Programming DNA molecular reactions at molecular and nanometer scales have been achieved, but achieving programmable autonomous behavior at submicron or larger scales remains challenging. This study presents a mechanism of meta-DNA strand displacement reactions (M-SDRs) mediated solely by meta-toehold (M-toehold) using versatile submicron building blocks of meta-DNA (M-DNA). M-SDR emulates the toehold binding and branch migration processes and shows potential for programming autonomous behavior at the cellular level.

Summary: Brillouin light scattering (BLS) is a promising method for cell imaging and characterisation, offering elasticity-related contrast, optical resolution, and label-free operation. Phonon microscopy, which detects BLS from laser generated coherent phonon fields, presents challenges in imaging single cells due to poor signal to noise ratio and acquisition time. Recent advances in instrumentation have enabled imaging of fixed and living cells with improved axial resolution and accuracy.

Summary: This study presents the characterization results of integrated vacuum gaps using cylindrical capacitors manufactured with standard semiconductor technology. The study reveals that the breakdown field of the vacuum gaps can reach up to 6 x 10^9 V/m under high electric fields, avoiding breakdown due to avalanche discharge. The study also finds that the tunneling current in the vacuum gaps occurs at higher voltages compared to equivalent dielectric layers.

Summary: The capability of bacterial biofilms, specifically Acinetobacter sp., in removing sub-micron-sized PS microplastics through biosorption was evaluated in this study. The biosorption of 430 nm-PS microplastics onto the Acinetobacter sp. biofilm was well explained by the pseudo-second-order kinetics and Freundlich isotherm models. However, the biosorption capability of Acinetobacter sp. diminished after incubation with the 430 nm-PS microplastics in environmental freshwaters for 7 days.

Summary: This study investigates the formation of heteroaggregates from sub-micron particles in ProCell type spouted bed equipment. The high inlet air velocities in the special spouted bed can promote aggregate breakage and rearrangement. The mixing of sub-micron sized particles is achieved at the sub-agglomerate level, as shown by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS).

Summary: This study focuses on the design and testing of glass nozzles for producing liquid sheets. The nozzles are made by chemically etching a single converging channel into glass wafers using lithographic methods. The experiment demonstrates the operation of the nozzles in both ambient air and vacuum conditions. The thickness of the produced liquid sheets is found to be independent of liquid flow rate but dependent on the nozzle outlet area. Surface roughness of the sheets is influenced by the nozzle surface finish, with polished nozzles exhibiting a roughness on the order of 10 nm. The study also presents electron transmission data for various sheet thicknesses and determines the charge pair distribution function for D2O based on electron scattering data.

Summary: This article investigates the role of proton exchange membranes (PEM) in fuel cells and other electrochemical applications, and finds that membrane thickness is crucial for membrane performance, cost, and stability. By using ultra-high molecular weight polyethylene (UHMWPE) material and precise interfacial engineering, a composite membrane with a thickness of 1.6 micrometers is prepared, consisting of a 300 nanometer thin porous membrane and interior Nafion. This membrane demonstrates high membrane power density in practical applications, providing new insights for addressing the performance-stability paradox of PEM.

Summary: Construction of sub-micron carbon fibers using porous carbon black as the building unit and PAN-based pyrolytic carbon as the binder results in fibers with high porosity, specific surface area, and N/O-containing surface. The CB content significantly affects the thermal stability, flexibility, and conductivity of the fibers, which exhibit a considerable specific capacitance and excellent cycling stability for use in flexible supercapacitor electrodes.

Summary: This work demonstrates the feasibility of using sub-micron size metal oxides as a sustainable charge storage material in supercapacitors. Two different synthesis methods were used to produce sub-micron bismuth vanadate particles. The electrochemical performance of the particles showed that the particles synthesized using the sonochemical method were more stable and had higher specific capacitance compared to the particles synthesized using the co-precipitation method. Overall, this work has a rating of 8 out of 10.
