Harvesting atmospheric water by solar regenerated desiccants is a promising source that energy-efficient, environmentally clean, and viable. However, the generated amounts of are still insignificant. Therefore, more intensive fundamental research must be undertaken involving experiments modeling. This paper describes several experiments, which were conducted to predict improve behavior absorpti...

Atmospheric water harvesting (AWH) has been an appealing prospect for decades to overcome scarcity in remote areas. Adsorption-based AWH technologies have gained popularity due their adaptability, and applicability using low-grade heat sources. This study presents up-to-date future possibilities of adsorbents systems adsorption-based AWH. In this review, in-depth advancements adsorbent material...

Orotic acid (OTA) is reported to exist in the anhydrous (AH), monohydrate (Hy1), and dimethyl sulfoxide monosolvate (SDMSO) forms. In this study we investigate the (de)hydration/desolvation behavior, aiming at an understanding of the elusive structural features of anhydrous OTA by a combination of experimental and computational techniques, namely, thermal analytical methods, gravimetric moistur...

The pesticides industry needs to look differently from the existing basis that toxic materials are required in order to eliminate pests and weeds from food crops. New generation of pesticides will be motivated by a knowledge of metabolic pathways. The article reviews the effectiveness of several classes of natural pest control agents such as: pheromones, allelopathic chemicals, toxicants from t...

BACKGROUND A large gap for the support of point-of-care testing is the availability of reagents to support quality control (QC) of diagnostic assays along the supply chain from the manufacturer to the end user. While reagents and systems exist to support QC of laboratory screening tests for glucose-6-phosphate dehydrogenase (G6PD) deficiency, they are not configured appropriately to support poi...
