Preparation of dense alumina (Al₂O₃) thin film through atomic layer deposition (ALD) provides a pathway to achieve the encapsulation of organic light emitting devices (OLED). Unlike traditional ALD which is usually executed at higher reaction n temperatures that may affect the performance of OLED, this application discusses the development on preparation of ALD thin film at a low temperature. O...

Introduction and Strategy Discovery of the extraordinary activity of sulfated zirconia for n-butane isomerization below 373K has led to numerous efforts to investigate and correlate structure, acidity, and reactivity of this material. Although a large data set has been obtained from powdered sulfated zirconia no consistent picture has evolved that satisfactorily describes acidity and reactivity...

Pullulan, a water soluble, bioadhesive and biocompatible biopolymer is used as an efficient matrix for enalapril maleate film preparation. The obtained film contains as much as 67% of enalapril maleate, relative to the initial amount used for experiments. The drug content was evaluated by using 1 H-NMR and UV-vis spectroscopy. The pullulanenalaprilmaleate blends exhibit good physicochemical pro...

Arrayed microchannels with dimensions of tens to hundreds of micrometres show great potential for application in microfluidics, microreactor devices and other areas. In this work, we report the formation of ordered arrays of cracks on solution-cast colloidal films, and the preparation of radially aligned microchannels. The polymer film coating enables the colloidal film to be detached from the ...

The non-biodegradable nature of plastic packaging has brought about an attention in bio-basedpackaging materials. Edible composite films were prepared using soy protein concentrate (SPC) and pullulan(PUL) biopolymer at five different ratio (100:0; 70:30; 50:50; 30:70 and 0:100) with glycerol as plasticizer bycasting-evaporation method. The thickness, mechanical properties, water vapor permeabil...
