Summary: The reflective characteristics of multilayer mirrors based on Ru/Y were investigated, revealing a reflection coefficient of 38.5% at an operating wavelength of 9.4 nm. It was found that the deposition of B-4 C barrier layers onto Y layers significantly increases the reflection coefficient compared to structures without barrier layers. Additionally, mirrors optimized for 11.4 nm achieved a reflectance of 54%, which approaches the theoretical limit for these materials.

Summary: In order to reduce the impact of CO2 on the environment, CO2 capture has gained research interest. Hierarchically porous carbon frameworks (CPI-TPUs) derived from polyimide (PI)/thermoplastic polyurethane (TPU) composite aerogels (PI-TPUs) with mesopores and macropores exhibit enhanced CO2 capture performance. The synergistic effect of hierarchically pores, higher specific area, and electron-rich heteroatoms leads to improved CO2 uptake capacity for CPI-TPU2 (2.21 mmol/g, 298 K) compared to pure CPI and PI-TPUs. CPI-TPUs with a pore volume ratio of mesopores/macropores to total pores in the range of 6-21 show high CO2 uptake performance and can serve as promising CO2 adsorbents.

Summary: Inspired by biomimetic membranes, the liposomes-based reverse osmosis membranes were prepared by incorporating C14lyso liposomes into the polyamide selective layer. The concentration of liposomes could regulate the structure and performance of the membranes. The optimal membrane with a C14lyso concentration of 0.25 mg/mL showed high water permeance and NaCl rejection.

Summary: This paper examines a new approach for synthesizing Parylene-metal multilayers. The metal layers are obtained from a metal salt solution and a plasma reduction treatment. This one-pot synthesis process requires less resources and energy compared to electron beam sputtering processes. The Parylene coatings are obtained after plasma treatments with Parylene C. The process provides ultra-thin metal salt layers and Parylene layers with good tensile strength and wettability.

Summary: In high NA extreme ultraviolet lithography, using a Ru/Si multilayer with PSM absorber is found to be more effective than Mo/Si multilayer in addressing patterning issues that arise with increasing NA. The Ru/Si multilayer offers a smaller best-focus range, improved image contrast, and more stable patterning, even with reduced layer numbers.

Summary: The performance of multilayer MoS2 transistors was significantly enhanced by photoresist encapsulation, leading to improvements in on/off-current ratio, field-effect mobility, contact resistance, and intrinsic carrier mobility. The Raman spectra indicated n-type doping in the photoresist-encapsulated MoS2, potentially attributed to the electropositive hydroxyl groups in the photoresist. Furthermore, the operation of these transistors remained stable in ambient air for at least one month, demonstrating the effectiveness of simple photoresist encapsulation as a performance booster for MoS2 and other transition metal dichalcogenides transistors.

Summary: This paper investigates the effects of variable cross-section flow field design on the performance of proton exchange membrane fuel cells (PEMFCs). The results show that the sidewall contraction flow field can improve the output performance of the fuel cell and achieve higher oxygen concentration and lower water concentration. The optimal parameters are determined to be N=6 sidewall contractions, Lf=6 mm length, and Wf=1.2 mm width.

Summary: In this paper, a large-size double-channel multilayer mirror is developed using W/Si and Ru/C multilayers. The RMS error of the thickness of the W/Si multilayer is 0.30% and 0.19%, and that of the Ru/C multilayers is 0.39% and 0.20%, within the range of 320 mm length and 20 mm width. Based on the optimized experimental results, W/Si and Ru/C multilayers are deposited on a high-precision Si plane mirror with a size of 350 mmx60 mm in two stripes, and the estimated reflectivity (8.04 keV) is 68% and 65%, respectively. The multilayer mirrors meet the requirements of the beamline and are successfully applied in the membrane protein beamline of SSRF.

Summary: This study presents the structural characterization of Al/Sc-based periodic multilayer coatings for the extreme ultraviolet (EUV) spectral range, revealing the layer structure and interfacial effects, as well as onset of crystallization. The Al/Sc layer model is validated and refined through EUV reflectance measurements across an extended wavelength range. The study also explores the aging properties and spectral response of optimized two-and tri-material multilayers, including Al/Sc, Al/Sc/SiC, and Mo/Al/Sc, using similar EUV reflectance measurements.

Summary: This research describes a standardized method for characterizing the virulence profile of the grapevine downy mildew pathogen Plasmopara viticola. By inoculating 33 European strains onto six grapevine varieties with different resistance factors, the researchers were able to assess sporulation levels and the intensity of the grapevine hypersensitive response. They identified multiple pathotypes and detected breakdown of resistance in certain strains. This method enables early detection of resistance breakdown and monitoring of pathogen evolution.
