The use of traditional biocides to halt or reduce biodeterioration is increasingly deterred, due risks for human health and the environment, as well potential interference with stone materials. Alternative eco-friendly substances are needed limit these issues. Here we aim evaluate devitalization lichens by a new bio-based product: wood distillate (also known pyroligneous acid), by-product plant...

Hydrogen-rich Gynostemma pentaphyllum Makino distillate (HRGD) consists of steam with hydrogen gas. Although both G. and hydrogen-rich water are well known for their biological medical benefits, there is a lack information on safety toxicity in vivo acute oral test vitro cytotoxicity method. The current study aimed to assess the HRGD as part evaluation using rat human cell models. was administe...

This paper presents simulation studies on the recovery of Acetonitrile from aqueous waste pharmaceutical processes. The focus is atmospheric distillation in two sequential columns to understand separation feasibility system; first column produces a distillate azeotropic composition, which mixed with fresh stream and fed second column, 99.9% pure residue. effect reflux ratio, reboiler duty flowr...
