Thermal energy transport is of great importance in lignocellulose pyrolysis for biofuels. The thermophysical properties of lignocellulose significantly affect the overall properties of bio-composites and the related thermal transport. In this work, cell-scale lignocellulose (mono-layer plant cells) is prepared to characterize their thermal properties from room temperature down to ∼ 40 K. The th...

In this paper, we show that the kinetics of annealing of light-induced defects in microcrystalline silicon is similar to that of amorphous silicon. Dilution series of pin and nip single-junction microcrystalline silicon (μc-Si:H) solar cells were light-soaked (AM 1.5, 1000h at 50°C). Their relative efficiency loss between initial and degraded states depends on the i-layer crystallinity. Subsequ...

The ability to characterize the phase of the intrinsic (i) layers incorporated into amorphous silicon [a-Si:H] and microcrystalline silicon [μc-Si:H] thin film solar cells is critically important for cell optimization. In this research, a new method has been developed to extract the thickness evolution of the μc-Si:H volume fraction in mixed phase amorphous + microcrystalline silicon [(a+μc)-Si...

Several representative ionic liquids (ILs) were synthesized, and [Emim]OAc was chosen as environment-friendly solvent for enzymatic in situ saccharification in view of its biocompatibility with both natural and microcrystalline cellulose, as well as its enzymatic activity. With the microwave pretreatment of natural and microcrystalline cellulose, directly enhancing the in situ enzymatic sacchar...

In the microcrystalline regime, the electrical (impedance/dielectric) behavior of grain boundarycontrolled electroceramics is well described by the “brick-layer model” (BLM). In the nanocrystalline regime, however, grain boundary layers can represent a significant volume fraction of the overall microstructure. Simple boundary-layer models no longer adequately describe the electrical properties ...

Purpose. Pseudoseptic arthritis is an acute inflammatory monoarthritis with a sterile synovial gram stain and culture. Pseudoseptic arthritis has been previously described in the literature in a variety of settings including rheumatoid arthritis and microcrystalline disease. Despite pseudoseptic arthritis being a described entity, there is little published data on this topic with no published r...

This paper reports the mechanoluminescence (ML) induced by impulsive excitation of γ irradiated terbium doped KCl single crystals and powder. The KCl crystals having different concentrations of terbium were prepared by melt technique (slow cooling).The crystals of small sizes were cleaved from grown crystal block and crushed to obtain powder or microcrystalline powder. The annealed samples were...

The main objective of the research work is to improve the solubility and dissolution rate of olmesartan medoxomil by complexation with HP β-Cyclodextrins. The inclusion complexes were prepared by kneading method and solvent evaporation method. The prepared complexes were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and by scanning electron microscopy (SEM). The FTIR spectra o...

A randomised trial comparing the topical application of 1% fusidic acid with 0.3% gentamicin solution in the reduction of the normal preoperative lid and conjunctival microbial flora was performed. Forty patients awaiting cataract surgery were randomly divided into two groups consisting of 20 patients each. The first group received a 1% microcrystalline suspension of fusidic acid, the second 0....

Microcrystalline and nanocrystalline AlCrFeCoNi high-entropy alloy (HEA) coatings were applied on Inconel 718 superalloy using the atmospheric plasma spraying (APS) process. The high-temperature oxidation behavior of microcrystalline HEA-coated was examined at 1100 °C under air atmosphere for 50 cycles cyclic heating cooling (1 h each cycle). kinetics both nanocrystalline- microcrystalline-coat...
