The development of butyl acetate sensors with high sensitivity and selectivity has been highly desirable for its harmful effects on human health. In this work, we developed a high-performance butyl acetate sensor based on vascular bundle structure Zn SnO nanomaterial derived from maize straw. The vascular bundle structure Zn SnO with higher specific surface area obtained by calcination to remove the maize straw template, plays the dual role of accelerating the diffusion of gas molecules and providing more active sites. Our research showed that the sensor had a response of 18 to 100 ppm butyl acetate at a working temperature of 250 °C, with a fast response recovery rate (18 s/25 s), which showed significant improvement compared to the Zn SnO sensor prepared without templates. The improved performance can be attributed to the cross-linked nanoparticle chains and gas collision mechanism of the sensor. These findings highlight the potential of our sensor for the detection of butyl acetate gas.

Composite flat-sheet membranes functionalized with imidazolium-based ionic liquids (ILs) grafted to poly(vinyl alcohol)/glutaraldehyde as a catalytic layer were developed to enhance the esterification between -butanol and acetic acid. The functionalized membranes were produced dip-coating commercial pervaporation membranes, and two distinct Brønsted-acidic ILs with an imidazolium-based cation and different (hydrogen sulfate [HSO] or bromide [Br]) anions were compared. Compact, 12 μm-thick, defect-free catalytic layers were observed on top of the pervaporation membrane supports, and the determined penetration depth of the ILs confirmed their presence in the upper part of the coating.

An increase in the consumer demand and the availability of gluten-free products has led to several brewers investigating brewing with grains other than barley. The primary grain of choice has been sorghum. These new gluten-free beers have a unique flavor and aroma, which previous research has shown is the result of differences in concentration for key chemical compounds, including ethyl butyrate, butyl acetate, isoamyl acetate, ethyl caproate, hexyl acetate, 1-octanol, nonanal, ethyl octanoate, and ethyl decanoate.

It is generally believed that there is a great relationship between hangover and the age of Baijiu. However, what factors make Baijiu (stored for a long time) feel better after drinking has not been well explained. In this study, ethanol metabolism, oxidation stress, inflammation and release of inhibitory neurotransmitter were selected as the indicator of hangover.
