An Ni2Al3 coating was prepared via the electrodeposition of nickel followed by pack aluminization. Polarization curve and electrochemical impedance spectroscopy were performed to study the room temperature corrosion behavior of the coating in a 3.5 wt. % NaCl solution. The long-term impedance of the coating was also investigated after immersion for 30 days. Results show that the Ni2Al3 coating ...

Whey protein oxygen-barrier coatings on peanuts are not effective, due to incomplete peanut-surface coverage, as well as some cracking and flaking of the coating. Addition of sorbitan laurate (Span 20) in the whey protein coating solution up to the critical micelle concentration (cmc) of 0.05% (w/w) significantly improved coating coverage to 88% of the peanut surface. Increasing the Span 20 con...

In recent years, the use of edible coatings as a carrier of food additives and antimicrobial compounds in fishery products has been considered. This study was carried out to evaluate the effects of 2% chitosan coating singly or combined with 0.1% grape seed extract (GSE) on microbial (mesophilic and psychrophilic count), chemical (TBA, pH and PV) and sensorial properties of rainbow trout fillet...

Inoculation of the bacterial cells of microbial seed coating agents (SCAs) into the environment may result in limited survival and colonization. Therefore, the application efficacy of an encapsulated microbial seed coating agent (ESCA) was investigated on potted cotton plants; the agent was prepared with polyvinyl alcohol, sodium dodecyl sulfate, bentonite, and microencapsulated Bacillus subtil...

BN nanotubes are coated with SnO(2) by a simple chemical reaction in solution. BN nanotubes are stirred inside a SnCl(2) solution at room temperature for 1 h. The coating is uniform with complete coverage. The coating thickness is typically 1-5 nm. The coating layer contains SnO(2) nanoparticles with sizes ranging from 1 to 5 nm.

The combination of the high mechanical strength of metals with the osteoconductive properties of calcium phosphates make hydroxyapatite coatings on titanium implants widely used in orthopedic surgery. However, the most popular coating method, plasma spraying, exhibits some important drawbacks: the inability to cover porous implants and to incorporate biologically active agents, delamination, an...

A simple, rapid, and precise dynamic coating capillary electrophoretic separation method for water-soluble humic substances is proposed. An aqueous solution containing hydroxyethyl cellulose (HEC), polyethylene glycol (PEG), and pH buffer component was employed for both the dynamic coating agent and the separation medium. The procedure for the coating of the capillary inner wall was simply fill...

Citrus genus is known as one of the world's major economic agricultural products. In the current research, a method is reported for artificial seed production technology by shoot tips in Citrus sinensis.var. Thamson navel. Alginate is one of the most efficient gelling agents in the production of capsule coating in artificial seeding technique. In the current research, impact of different consti...

OBJECTIVES The aim of this work was to evaluate saliva and tongue coating pH in oral healthy patients with morning bad breath before and after use of different oral mouthrinses. MATERIAL AND METHODS Saliva and tongue coating pH of 50 patients allocated in 5 groups were measured respectively by a digital pHmeter and color pH indicators, before, immediately after and 30 min after rinsing 5 diff...
