Abstract The analysis of low-energy electron diffraction (LEED) intensities from quasicrystal surfaces requires the use of periodic model structures that contain the same structure features as the quasicrystal. In this paper, we present the analysis of LEED data from 10-fold decagonal Al–Co–Ni using the W approximant…
This paper analyzes the effect of ultrasound on a batch wattle bark tannin extraction process. Extraction from wattle bark presents a unique case of a two-component system in the form of condensed tannins and non-tannins. Hence, quantitative analysis of tannin content in the extract by spectrophotometery as well as to…
Zn095Co005O films were prepared under different oxygen partial pressure P by magnetron sputtering. The effect of P on the magnetic and electrical properties was investigated. The effect of oxygen vacancy on the magnetic properties was also calculated by first-principles calculation. The experimental results indicate…
As researchers strive to understand the interplay between the complex molecular systems that make up living cells, tools for characterizing the interactions between the various players involved have developed. Small-angle neutron scattering (SANS) plays an important role in building a molecular-level understanding of…
The aim of this research was to study the electrical conductivity for electrical conductivity of chlorophyll with polythiophene (PT) thin film on indium tin oxide as P‐N heterojunction solar cell. The polythiophene thin film is deposited to the Indium Tin Oxide (ITO) substrate using electrochemistry method. The chloro…
-doped (GDC) thin-film electrolytes with lateral-type electrode geometry for integrated single-chamber solid oxide fuel cells (SOFCs) were prepared by dc/radio-frequency reactive magnetron sputtering. The morphological and electrical properties of the GDC films with various electrode geometries were characterized by X…
To identify the potent source of protease that can be used as ideal milk clotting enzyme(s) in handmade dairy products of latex obtained from twenty one plant species belonging to Northern (Khandesh) region of Maharashtra, India, was analyzed for caseinolytic activity, milk clotting activity, gelatinolytic activity an…
Natural fibers are gaining progressive account as a renewable, environmentally acceptable, \nand biodegradable reinforcing fibre which combine acceptable mechanical properties with \na low density. The utilization of biomass (lignocelluloses) for the processing of novel \ncomposites has attracted growing i…
The blowing extrusion is one of the most widely used techniques for the production of hollow plastic products. In order to improve the efficiency of designing plastics processing the blow products from thermoplastic materials used in Computer Aided Engineering software. This paper presents the blowing container simula…
Oligo(ethylene terephthalate)(OET), oligo(ethylene succinate-co-terephthalate)(OEST) and oligo(butylene succinate-co-terephthalate)(OBST), which are part of the poly(ethylene terephthalate)(PET) oligomer, were synthesized. Degradation test of oligomers carried out by the presence of lipase PS. There were two objective…
This study demonstrates recent advances in microfibrillated cellulose (MFC) research. This novel material, which is mostly com- posed of nano-sized cellulose fibrils seems to have large potential within several applications. Three case studies are considered, i) MFC films that may be applied for packaging applications…
Temperature-progremmed desorption (TPD) method is useful for analyzing the surface structure, that is, oxygen-containing functional groups of carbon materials. This review introduced the analysis of the activated carbon fiber sample by TPD method, and discussed the change in the functional groups caused by the oxidati…
