He has published 150+ SCI-peer reviewed papers in reputed journals and has many National Awards (e.g., Professor Yen-Ping Shih Best Paper Awards of 2007, 2011, 2013 and 2016 from Taiwan Institute of Chemical Engineers).      

Abstract:

This first-attempt study used extracts of appropriate antioxidant abundant Camellia and non-Camellia tea and medicinal herbs as model electron shuttles (ESs) to stably augment bioelectricity generation performance in microbial fuel cells (MFCs).  As ESs (or redox mediators) could stimulate electron transport phenomena by considerable reduction of electron transfer resistance, the efficiency of power generation for energy extraction in microbial fuel cells (MFCs) could be appreicably augmented.  That is, using environmentally friendly natural bioresource as green bioresource of ESs is the most promising to sustainable practicability.  As comparison of power-density profiles indicated, supplement of Camellia tea extracts would be the most appropriate, then followed non-Camellia Chrysanthemum tea and medicinal herbs.  Moreover, antioxidant activities, total phenolic contents and power stimulating activities were all electrochemically associated.  In particular, the extract of unfermented Camellia tea (i.e., green tea) was the most promising ESs to augment bioenergy extraction compared to other refreshing medicinal herb extracts

Abstract:

The effect of adding various combinations of dibenzyl disulfide (DBDS), 2,6-di-tert-butyl-p-cresol (DBPC), 2,6-di-tert-butyl-phenol (DBP) and 1,2,3-benzotriazole (BTA) to a mineral transformer oil on the corrosion of copper strips coated with kraft paper dipped in that oil and aged under accelerated oxidation conditions is assessed qualitatively by visual inspection of the copper strips (IEC 62535 standard method) and quantitatively by determination of the additives left after the ageing period. Qualitative examination shows that BTA protects against copper corrosion but once depleted from the oil matrix and presumably stripped from the copper surface DBDS attacks the copper and causes it to corrode. For continued protection against corrosion, BTA needs to be regularly replenished since qualitative examination also shows that if BTA is excluded from the added chemicals no significant corrosion suppression takes place. The quantitative method showed slight depletion of DBPC and DBP in the presence of DBDS, meanwhile DBDS showed drastic depletion after 120 hours of ageing. These observations point to a minimal role for DBPC and DBP antioxidants as corrosion suppressors when DBDS is present in the mineral oil. When either of the DBPC or DBP antioxidants was added to oil samples already containing DBDS and BTA, their depletion was very limited over 120 hours of ageing and a minimal corrosion was observed on the copper strips, indicating that either DBPC or DBP assists BTA in mitigating copper corrosion by DBDS.
