Waste Sawdust‐Derived Hard Carbon Anodes With Engineered Interlayer Spacing for Sodium‐Ion Batteries Exhibiting High Initial Coulombic Efficiency

open access: yesCarbon Energy, EarlyView.
It is demonstrated that waste sawdust, a green, eco‐friendly, and low‐cost biomass byproduct, can be converted into high‐performance hard carbon through the application of a precisely controlled heating rate. This strategy is optimized and validated through first‐principles calculations, achieving precise control over interlayer spacing and pore ...

ACCIDENTAL OVERDOSE OF PHENOLPHTHALEIN. [PDF]

open access: yesJournal of the American Medical Association, 1908
For a year past phenolphthalein has been a very popular laxative, and the following experience may be worth reporting: A few months ago I was called to the country to care for a child, aged 3 years and a few months. On my arrival I was informed that the child had taken twenty-five or more one-grain phenolphthalein tablets of a reliable make.

Optimized Copper Pretreatment Protocols for Premium Green Raisin Production via Vacuum Impregnation and Metallo‐Complex Stabilization

open access: yesFuture Postharvest and Food, EarlyView.
ABSTRACT Green raisin production is limited by rapid chlorophyll degradation during drying. This study evaluated copper metallo‐complex formation to stabilize green pigmentation in Vitis vinifera cv. Thompson Seedless grapes. Pretreatments with copper sulfate (CuSO4) pentahydrate (2%–6% w/v) were applied via dipping and vacuum impregnation (2–10 min ...

Valorization of Pineapple Peel and Mature Coconut Water to Produce Vinegar

open access: yesFuture Postharvest and Food, EarlyView.
Pineapple peel waste and mature coconut water were utilized as low‐cost substrates for vinegar production through a two‐stage fermentation process. During alcoholic fermentation, sugars in the substrate were converted into ethanol by Saccharomyces cerevisiae.

CO2 capture by accelerated weathering of limestone using waste limestone at elevated CO2 concentrations

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Accelerated weathering of limestone (AWL) using waste limestone (WL) for industrially relevant CO2 capture remains underexplored. Previous studies on potable water‐operated AWL have mainly examined idealised conditions, such as the use of high‐purity limestone or relatively low CO2 concentrations, which may not reflect selected ...

THE CLINICAL USE OF PHENOLPHTHALEIN [PDF]

open access: yesJournal of the American Medical Association, 1910
The clinical use of phenolphthalein, so far as our present knowledge goes, is that of a purgative, and as such it is a valuable and efficient remedy. It is a yellowish powder, being soluble in alcohol and in aqueous solutions of hydroxids and carbonates, and but very slightly soluble in water. Phenolphthalein is a definite chemical compound, belongs to

The effect of light supplementation on the changes in outer and inner fruit quality of different Selenicereus spp. cultivars

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Selenicereus spp., belonging to the Cactaceae family, produces pitaya, a fruit recognized for its exotic appearance and rich phytochemical composition. In regions with shorter photoperiods, flowering and fruit development are limited, making light supplementation a promising strategy.
