In the present investigation, glycerol and dimethyl carbonate were transesterified using a Li/Mg/K modified zeolite beta catalyst to synthesize glycerol carbonate. The various prepared zeolite catalysts were characterized using XRD, FE-SEM, EDS, HR-TEM, XPS, and DLS techniques. Many tests were conducted to optimize the reaction conditions to obtain the highest yield of glycerol carbonate by changing the catalyst concentration (5–20 wt%), glycerol-to-dimethyl carbonate mole ratio (1: 2–1: 6), and reaction temperature (65–105 °C). A maximum of 81.48% glycerol carbonate was obtained under optimized reaction conditions (a glycerol: dimethyl carbonate mole ratio of 1: 5, a Li 20β dosage of 10 wt% w.r.t. GLY, a temperature of 95 °C, and a time of 5 h). The experimental data followed second-order reaction kinetics with an activation energy of 34.60 kJ mol −1.

Luteolin, a flavonoid, is mainly found in various vegetables and fruits, including carrots, cabbages, onions, parsley, apples, broccoli, and peppers. Extensive research in vivo and in vitro has been performed to explore its role in disease prevention and treatment. Moreover, this compound possesses the ability to combat cancer by modulating cell-signaling pathways across various types of cancer. The studies have confirmed that luteolin can inhibit cancer-cell survival and proliferation, angiogenesis, invasion, metastasis, mTOR/PI3K/Akt, STAT3, Wnt/β-catenin, and cell-cycle arrest, and induce apoptosis. Further, scientific evidence describes that this compound plays a vital role in the up/down-regulation of microRNAs (miRNAs) in cancer therapy. This review aims to outline the anti-cancer mechanisms of this compound and its molecular targets. However, a knowledge gap remains regarding the studies on its safety and efficacy and clinical trials. Therefore, it is essential to conduct more research based on safety, efficacy, and clinical trials to explore the beneficial role of this compound in disease management, including cancer.

The urgent need for effective and sustainable electrocatalytic nitrate reduction to mitigate global water contamination and foster fossil-free ammonia generation has driven extensive exploration of bimetallic non-noble metals in electrochemical applications. Herein, we present the development of an electrocatalyst, namely FeCu phosphide (Fe–CuP), which demonstrates high efficiency in the reduction of nitrate. The prepared samples exhibit exceptional catalytic activity in the electrocatalytic reduction of nitrate to NH 3in a neutral electrolyte. It is noteworthy that the Faraday efficiency reaches an impressive 89% at −1.5 V ( vs. SCE), with NH 3
