Article Abstract
Yttrium aluminum garnet doped with europium with an additional impurity phase of yttrium vanadate doped europium has been prepared in different ways: synthesized by a sol-gel route and mechanically mixed in a mortar. The obtained samples were characterized by X-ray diffraction analysis, and scanning electron microscopy. Photoluminescence spectra were recorded to understand the role of the impurity phase in the garnet's optical properties. The impurity phase showed a significant contribution to the optical properties of YAlO:1%Eu.
Boosting the stability of cesium/formamidinium (Cs/FA) based perovskite solar cells (PSCs) has received tremendous attention. However, the crystallization of perovskites usually undergoes complex intermediate phase transitions and ion loss processes, which seriously degrade the efficiency and stability of PSCs. Herein, iodine monobromide (IBr, an interhalogen) is incorporated into the precursor solution to regulate the perovskite crystallization process.
Supercritical-dense phase CO pipeline transportation has been proven to have excellent economic and safety benefits for long-distance CO transportation in large-scale. Hydrates are easily generated in the high-pressure and low-temperature sections, resulting in blockage, so it is necessary to build the prediction model for hydrate formation in the long-distance CO pipeline transportation. In the prediction model of hydrate formation of our work, the phase equilibrium was determined by the Chen-Guo model, and the lateral growth of hydrate was calculated by the comprehensive growth model, and the hydrate growth was estimated by analogy with the condensation process.
Small molecules and antibodies have dominated the pharmaceutical landscape for decades. However, limitations associated with therapeutic targets deemed "undruggable" and progress in biology and chemistry have led to the blossoming of drug modalities and therapeutic approaches. In 2023, a high number of 9 oligonucleotide and peptide products were approved by the Food and Drug Administration (FDA), accounting for 16% of all drugs approved.

As the energy industries, such as secondary batteries and fuel cells, expand rapidly, the demand for transition metals used as electrode materials is increasing, which has led to a rise in their prices. One promising strategy to address these challenges is upcycling, which involves recycling transition metal-based waste from various industries. In this study, a heterostructure electrocatalyst for anion exchange membrane water electrolysis is developed by upcycling iron-based waste from the automotive industry.
Oil-water separation materials with specialized wettability have garnered significant attention in the field of oil-water separation due to the advantages of simple use and no secondary pollution. However, the adsorptive contamination of the filter surface by impurity phases and surfactants can cause a shift in the wettability of the filter surface. For efficient oil-water separation and improved resistance to adherent contamination on the oil-water separation membrane surface, herein, superwetted Cu nanofilms and smooth hydrophobic surfaces were prepared on SSM substrates by one-step electrodeposition and immersion methods, respectively.
