The molecular weight of a polymer determines key optoelectronic device characteristics, such as internal morphology and charge transport. Therefore, it is important to ensure that polymer deposition techniques do not significantly alter the native polymer molecular weight. This work addresses polymers deposited by resonant infrared matrix-assisted pulsed laser evaporation (RIR-MAPLE). By using ...

Agarose emulsion droplet microfluidic technology for single copy emulsion PCR (ePCR) is a suitable technique for the detection of single copy DNA molecules. It improves the traditional ePCR by employing agarose with low melting and low gelling temperatures, which is coupled with PCR forward primers using Schiff-base reaction. Highly uniform monodisperse nanoliter agarose droplets each containin...

one small-scale double emulsion technique for incorporation of naja- naja oxiana venom into poly (lactide-co-glycolide) (plga) microspheres were developed and optimized. the effects of high speed homogenization on the double emulsion stability, microsphere size, entrapment efficiency and in vitro release of venom were studied. a stable double emulsion was verified by homogenization method. slow...

A stable oil emulsion rabies vaccine with a low viscosity was composed by a formula previously employed for Newcastle disease vaccine. Cattle developed high and sustained antibody levels, and guinea pigs were found to be solidly immune after a single injection of this vaccine. Antibody responses in cattle to 2 oil emulsion ephemeral fever vaccines were not satisfactory after a single injection,...

Emulsions have long been utilized to make materials for foods, drugs, cosmetics, and displays because of their efficient encapsulation properties. While they are most commonly made in bulk, recent advances in microfluidics have enabled the design and manipulation of emulsion drops with unprecedented control and flexibility, albeit only on a drop-bydrop basis. Multiple-phase emulsions of very hi...

Insomnia is becoming increasingly prevalent in the world general population. Therapies used by patients include over-the-counter therapies, herbal and dietary supplements, and pharmacological or nonpharmacological treatments. Among these, zolpidem is a pharmacological treatment popularly used for insomnia. Zolpidem is well tolerated and especially efficacious for initiation of sleep, and theref...

The objective of this work is to study the effect of the rapeseed oil content on the physical properties of whey protein emulsion films. For this purpose, whey protein films with the addition of 0, 1, 2 and 3% of rapeseed oil, and glycerol as a plasticizer were obtained by the casting method. Film-forming emulsions were evaluated and compared using light scattering granulometry. The Sauter mean...

Chitosan films (CF) with carvacrol (CAR) [0.5%, 1.0% and 1.5% v/v] were prepared by the emulsion method. The retained CAR, water solubility, water vapor permeability (WVP), optical, mechanical properties, antibacterial and antioxidant capacity of films were analyzed. The results indicate that the retention of CAR in the CF was ≈50%. The incorporation of CAR to CF decreased the water solubility,...
