Formation of coke during the esterification of pyrolysis bio-oil
, 2016 Coke formation during the esterification of bio-oil in alcohols and water over a solid acid catalyst Amberlyst 70 has been investigated. The amounts of coke formed from the acid-treatment of bio-oil in various alcohols are half of that in water. Alcohols

Expanding pitch-coke production
, 2011 The possibility of producing pitch coke from moderate-temperature pitch with the introduction of 10-30% dusty carbon fillers is investigated. The influence of graphitized dust and coal dust on the yield and quality of pitch coke is demonstrated.

Genetic Variation in ADHD‐Related Risk Genes in an Indigenous Population of the Amazon
American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.ABSTRACT Attention‐Deficit/Hyperactivity Disorder (ADHD) is a highly heritable neurodevelopmental disorder; however, its genetic architecture remains poorly explored in Indigenous populations. This study aimed to analyze and characterize genetic variation in 11 genes (ADGRL3, CDH8, DCC, DUSP6, FOXP1, FOXP2, MEF2C, PCDH7, SEMA6D, SORCS3, and ST3GAL3 ...
