The Reflectance Distribution of Shallow Cumulus and Its Environs From High Spatial Resolution ASTER Images

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract We investigate the 1D reflectance distribution of shallow cumulus as a function of cloud size, using high‐spatial‐resolution observations from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). Reflectance transects through clouds are compared between Inner Mongolia and Tropical Ocean.

Benchmarking Organic Photodiodes at the Noise Floor

Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.
A precise measurement framework based on a calibrated, ultra‐low‐noise automated setup with open‐source Python scripts enables accurate benchmarking of photodiodes. The unique combination of time‐dependent current measurement under dark conditions, followed by continuous‐wave faint illumination, facilitates reliable extraction of photocurrent near ...

Photons as Working Body for Photovoltaic Devices: Conversion of Photon to Electron from a Simplified Perspective

Advanced Theory and Simulations, Volume 9, Issue 1, January 2026.
In this work two models to study the photovoltaic response of solar cells are reported. The first model considers the bandgap effect to quantify the conversion of photons into electrons that makes up the photocurrent in the maximum electrical output power condition. The second model quantifies photocurrent in the short circuit condition from the energy

Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

Purification and characterization of recombinant human translation initiation factor eIF3

Protein Science, Volume 35, Issue 1, January 2026.
Abstract Eukaryotic translation initiation factor 3 (eIF3) is an essential factor in protein synthesis. In mammals, it is a ~800 kDa complex composed of 12–13 subunits. Biochemical and mechanistic studies of the function of eIF3 and its individual subunits in translation require purified eIF3.

Design and performance of the COOPS sun photometer

, 2019
The scattering of light in the atmosphere by aerosols has significant implications to the measurement of ocean color by satellite. Determining the effects of this scattering by measuring aerosol optical thickness (ζa) and sky radiance requires a Sun Photometer.
