این پژوهش به اکسید اسیون متانول در محیط قلیایی می پردازد. برای این منظور ابتدا ترسیب ذرات نیکل، پلاتین و نیکل – پلاتین بر روی زیر لایه کاغذ کربنی به روش آبکاری به شیوه ی جریان مستقیم استفاده شد. در ادامه مورفولوژی پوشش های ذرات فلزی بر روی کاغذ کربنی از طریق میکروسکوپ الکترونی روبشی بررسی و مطالعه شد. سپس خواص کاتالیستی الکترودها ی حاصل در اکسیداسیون متانول با استفاده از روشهای الکتروشیمیایی هم...

Studies have shown that people who require single room isolation while in hospital often feel lonely, sad, worried, bored and in need of information. A literature review identified only 16 papers reporting on the child's experience of isolation. Findings indicate that children feel lonely, are scared of the personal protective equipment and feel bored. Patients' parents feel guilty, worried and...

2,6-dichlorophenol indophenol (DCIP) and horseradish peroxidase (HRP) were coadsorbed on a porous carbon felt (CF) from their mixed aqueous solution under ultrasound irradiation for 5 min. The resulting DCIP and HRP-coadsorbed CF (DCIP/HRP-CF) showed an excellent bioelectrocatalytic activity for the reduction of H₂O₂. The coadsorption of DCIP together with HRP was essential to obtain larger bio...

A mixed microbial population naturally presents in seawater was used as active anodic biofilm of two Microbial Fuel Cells (MFCs), employing either a 2D commercial carbon felt or 3D carbon-coated Berl saddles as anode electrodes, with the aim to compare their electrochemical behavior under continuous operation. After an initial increase of the maximum power density, the felt-based cell reduced i...

Horseradish peroxidase (HRP) and thionine (Th) were co-adsorbed onto a porous carbon-felt (CF) from a mixed solution of HRP and Th to fabricate a CF-based bioelectrocatalytic flow-detector for H(2)O(2). The resulting HRP and Th co-adsorbed CF (HRP/Th-CF) was successfully used as a working electrode unit of a highly sensitive amperometric flow-H(2)O(2)-biosensor. Differing from the ordinary medi...

The chemical vapor deposition method is used to prepare CNT (carbon nanotube)/PCF (PAN-based carbon fiber felt) composite electrodes in this paper, with the surface morphology of CNT/PCF composites and electroadsorption desalination performance being studied. Results show such electrode materials with three-dimensional network nanostructures having a larger specific surface area and narrower mi...

What does it mean “feeling” something? How body activation and its perception is crucial in emotional experience? How it impact on the cognitive components of human emotions and their “appraisal” function, or is affected by them? Which are the different mental paths of emotional experiences?
