But a time may come when simple routines like idly washing your hands or doing the dishes won't be such casual tasks. That's because the water we depend on faces what many experts believe is an accelerating crisis—from climate change, pollution, extreme weather events, and deteriorating ...
baijiu; alcoholic beverages; hydrogen bond; ethanol–water; flavor; interaction 1. Introduction Baijiu is a unique and traditional distilled liquor in China with a history of more than 2000 years [1]. In 2021, the output of baijiu was 7.1563 billion liters (data from the China Alcoholic ...
The benefit of carrying out the Na+ to NH4+ ion exchange stage first is that the succeeding exchange of ions by means of catalytically-active metal is more competent [240]. What is more, the modus operandi of wet and incipient wetness impregnation has been brought into play for the ...
increasing the curvature of the interface. This is what happens at the interface between water and a hydrophobic surface such as a plastic mixing bowl or a windshield coated with oily material. A clean glass surface, by contrast, has -OH groups sticking out of it which readily attach to wate...

This plateau is likely because the chain entanglement contributes to the bond strength when the molecular weight is 20–40 kDa, as the entanglement molecular weight (Me) of PS is ~17 kDa24, and Mn of ~70–80 kDa was used for further studies (Supplementary Table 1). We used 300...
15) corroborates what is shown in Fig. 1b. Further detail reveals that a slight increase in summer precipitation emerged over the past 56 years for both the southern (Fig. 1c) and northern Tibetan plateau (Supplementary Fig. 15). However, as noted previously, beginning in 2004, the ...
