Inducción de la producción de lípidos totales en microalgas sometidas a estrés nutritivo
Acta Biológica Colombiana, 2016 Se evaluó la producción de lípidos totales en cinco especies de microalgas inducidas por la ausencia de nitrógeno. Las microalgas empleadas fueron Ankistrodesmus sp., Ankistrodesmus nannoselene, Chlorella sp., Scenedesmus sp.

Pirocatálisis de Biomasa a Hidrógeno
REVISTA DE CIENCIAS TECNOLÓGICAS, 2019 En este trabajo de investigación experimental se realiza la descomposición por pirólisis catalítica de la cáscara de nuez nogal (Juglans regia L.) en un intervalo de 400 °C a 800 ° C sobre óxido de zinc para la obtención de hidrógeno. El óxido de zinc se sintetiza a partir de nitrato de zinc hexahidratado a 500 °C en flujo de aire durante 1 hora.

Poljoprivredna biomasa, zašto ne? [PDF]
EGE : energetika, gospodarstvo, ekologija, etika, 2020 Energetsko iskorištavanje biomase izravnim izgaranjem u posljednjih je nekoliko godina doživjelo ponovni uzlet. Najveća toplinska učinkovitost i najmanje emisije štetnih tvari postižu se pri tome izgaranjem peletirane biomase. Sve stroži ekološki zahtjevi Europske unije, osobito u pogledu emisija štetnih tvari, zahtijevaju kontinuirani razvoj novih ...

Functional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...
