Pseudomonas aeruginosa and Streptococcus pyogenes are leading causes of medical device-associated infections. The capacity to establish and maintain these infections is thought to be associated with the ability to form surface-attached biofilms. In the present study, gallium nitrate was used to coat PVC plates and biofilm formation on the plates by Pseudomonas aeruginosa and Streptococcus pyoge...

The paper presents some results on the ability of palm oil polyol to replace petroleum-based in polyurethane (PU) synthesis. In this study, with amine functionality hydroxyl value (OH value) between 240 -253 mg KOH/g was used as component conventional polyol. Four different formulationsof coating have been prepared using pre-polymer process namely PU1, PU2, PU3 and PU4 isophorone diisocyanate r...

TiO2-SiO2 photocatalytic nanostructure film on windshield for self-cleaning purposes was prepared via sol–gel dip-coating method. TiO2 films were prepared on automotive glass pre-coated with a SiO2 layer by a dip-coating method followed by annealing at 500 °C for 30min. The films were characterized using X-ray diffraction XRD and scanning electron microscopy SEM, FE-SEM techniques. The TiO2-SiO...

This paper investigates the adsorption of different sized carboxyl methyl cellulose (CMC) onto talc particles (adsorption isotherm, adsorption reversibility), its consequences on the particles properties (electrophoretic mobility and surface wetting) and its effect on their dispersion (settling coefficient). Throughout the paper, the properties of talc particles dispersed in CMC solution are co...

application of edible coatings to enhance storage life of fresh fruit has recently been under considerable attention. this experiment was conducted in order to explore the effect of chitosan coating and storage temperature on the postharvest life of pomegranate (punica granatum l.) fruit. therefore, pomegranate fruits ‘rabbab-e-neyriz’ were dipped in 0, 1 and 2% aqueous chitosan solutions, air ...

We present efforts to mitigate debris from laser-produced Sn plasma by introducing a low energy pre-pulse while keeping high in-band conversion efficiency from laser to 13.5 nm extreme ultraviolet (EUV) light. The basic idea is to separate the processes of plasma production and 13.5 nm EUV light generation. A low energy pre-pulse is introduced to create a pre-plume; the main pulse then heats up...
