More thani a year ago I observed that the addition of a trace ot formaldehyde to acetic acid, which had beeni deprived by distillation' of its power to give, with sulphuric acid, Adamkiewicz'st reaction for proteids, restored to it its chromogenic power in a very markecd degree. As would be expected, it was found that the acetic acid was Inot essenitial, the formaldehyde, proteid anid sulphuric...
UNLABELLED BACKGROUND Lignocellulosic biomass, such as corn stover, is a potential raw material for ethanol production. One step in the process of producing ethanol from lignocellulose is enzymatic hydrolysis, which produces fermentable sugars from carbohydrates present in the corn stover in the form of cellulose and hemicellulose. A pretreatment step is crucial to achieve efficient conversi...
The growth of freshly formed aerosol particles can be the bottleneck in their survival to cloud condensation nuclei. It is therefore crucial to understand how particles grow in the atmosphere. Insufficient experimental data has impeded a profound understanding of nano-particle growth under atmospheric conditions. Here we study nano-particle growth in the CLOUD (Cosmics Leaving OUtdoors Droplets...
