Structure of Hydrophobic Ambient-Pressure-Dried Aerogels Prepared by Sonohydrolysis of Tetraethoxysilane with Additions of N,N-Dimethylformamide
(Amer Chemical Soc, 2014-02-04)
Silica wet gels with the same silica content were prepared by the sonohydrolysis of tetraethoxysilane (TEOS) with additions of dimethylformamide (DMF). DMF plays a role in the overall hydrolysis/gelification/aging step of ...
Temperatura de secagem e condições de armazenamento para manutenção da qualidade de pecãs com ou sem casca e diferentes umidades da amêndoa
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em AgronomiaCentro de Ciências Rurais, 2021-08-24)
The drying and storage of pecans are fundamental processes during the postharvest and require additional research to expand the possibilities for producers. Pecan moisture content reduction by drying process is necessary ...
