1 day ago · We have developed and successfully tested new environmental liquid cells for HAXPES studies using specially designed thin, low-stress silicon nitride membranes (15 to 25 nm thickness). The novel aspect is the fabrication of the membranes considering the geometry of the experimental setup, the dimensions of the beam and the use of platinum stripes to efficiently localize the membranes. The ...
2 days ago · The traditional approach to optical design faces limitations as photonic devices grow increasingly complex, requiring advanced functionalities. Recently, machine learning algorithms have gained significant interest for extracting structural designs from customized wavelength spectra, surpassing traditional simulation methods known for their time-consuming nature and resource-demanding ...
3 days ago · Additionally, the International Commission on Illumination (CIE) 1931 color space was assessed utilizing a distinct spectrophotometer model (3nh, TS7700). Furthermore, the Nicolet IS50 Fourier transform infrared spectroscopy (FTIR) instrument was leveraged to analyze both the transmittance spectra and IR reflectance properties of the PANI/CQDs and PANI films across varying potentials.
5 days ago · X-ray absorption fine structure (XAFS) spectroscopy is a characterization method that can be used to uncover information about the material electronic structure and structural information. XAFS analysis is generally performed by comparing available spectra and relies on experience and knowledge.
1 day ago · Dye-sensitized solar cells (DSSCs) present a promising solution for renewable energy due to their affordability, versatility, and sustainability, which are crucial in addressing climate change. This study explores the enhancement of low-cost, platinum-free counter-electrodes (CEs) for DSSCs through nitrogen (N2) plasma treatment, aimed at increasing photon absorption and the creation of active ...
4 days ago · In order to solve the problem of significantly shortened storage time of bananas in hot and humid environment (e.g., 30 °C and 90 % relative humidity), this paper reports the preparation of ZnO-TiO2-Bi2WO6 (ZTB) ternary heterojunction antimicrobial photocatalysts composite carboxymethyl chitosan film (ZTB/CMCS).
2 days ago · Catalysis stands as an indispensable cornerstone of modern society, underpinning the production of over 80% of manufactured goods and driving over 90% of industrial chemical processes. As the demand for more efficient and sustainable processes grows, better catalysts are needed. Understanding the working principles of catalysts is key, and over the last 50 years, surface-enhanced Raman ...
