Exploration of isoxanthohumol bioconversion from spent hops into 8-prenylnaringenin using resting cells of Eubacterium limosum [PDF]

open access: yes, 2020
Hops is an almost unique source of the potent phytoestrogen 8-prenylnaringenin (8-PN). As hops contain only low levels of 8-PN, synthesis may be more attractive than extraction.

Review and comparison of the methodology adopted for biodiesel production

open access: yesCarbon Resources Conversion
Biodiesel is a versatile energy source synthesized by trans esterifying various edible or nonedible oils using catalysts. It is preferable to diesel because of its higher flash points, reduced sulphur content, and biodegradability. Biodiesel synthesis by

Studies on the use of supercritical ammonia for ceramic nitride synthesis and fabrication [PDF]

open access: yes
The extractability of ammonia halides (including ammonium thiocyanate) formed as byproducts from the synthesis of Si(NH)2 via ammonolysis of the corresponding silicon tetrahalides using supercritical NH3 as the extraction medium was investigated.

Identifying dynamical systems with bifurcations from noisy partial observation [PDF]

open access: yes, 2012
Dynamical systems are used to model a variety of phenomena in which the bifurcation structure is a fundamental characteristic. Here we propose a statistical machine-learning approach to derive lowdimensional models that automatically integrate ...
