With ultrasonic echo method, characteristic of rubber thin layer was investigated, and theory of a survey the thin layer medium characteristic of frequency spectral analysis was deduced. A method is proposed to establish restoration function of frequency spectrum ratio of ultrasonic echoes under the condition of substrate material is covered and uncovered with the rubber thin layer. The results...

In this paper a novel anti-reflection (AR) coating based on silicon nano-bars is designed and its impact on the performance of crystalline silicon (c-Si) thin-film solar cells is extensively studied. Silicon nano-bars with optimized size and period are embedded on top of the active layer, under a 100nm Si3N4 layer. As a result of the proposed layer stack, an inhomogeneous intermediate layer wit...

'Murivenna' and 'Hemajeevanti Taila' were prepared and their analytical values were reported for standardization. Thin layer chromatography was also done.

Sringa Bhasma is an Ayurvedic medicine prescribed mainly for asthma. Physico chemical studies and thin layer chromatography for this medicine was worked out to laydown standards. The evolved parameters can be used for prescribing dependable standards to this medicine.

Thirty-three standard mycotoxins were assayed by thin-layer chromatography and by cytotoxicity in HEp-2 and Chang cells. Various levels of detection were found. The cytotoxicity test was significantly more sensitive than thin-layer chromatography for the trichothecenes and should be useful for screening extracts from animal feedstuffs for the presence of unknown mycotoxins.

Abstract The deposition process using the sputtering method is a technique that produces thin layer. can be used with some modifications made to system. One of identifications through results Optical Emission Spectroscopy (OES) spectrum. By analyzing OES spectrum in system, it seen condition plasma formation chamber. gas system Argon. varying voltage, flow rate, pressure and temperature substra...

Maternal obesity and gestational diabetes mellitus (GDM) are linked with impaired placental function early onset of non-communicable cardiometabolic diseases in offspring. Previous studies have highlighted that the dietary non-esterified fatty acids (NEFAs) palmitate (PA) oleate (OA), key metabolites associated maternal GDM, potential modulators lipid processing. Using BeWo cell line model, cur...

BACKGROUND Pseudomonas aeruginosa commonly infects the airways of patients with bronchiectasis. A study was undertaken to examine the relationship between infection of the airways with this pathogen, the morphological pattern of bronchiectasis on thin section computed tomographic (CT) scanning, symptom duration, smoking habits of the patients, and the presence of airflow obstruction. METHODS ...

We present a route for the preparation of cross-sectional TEM specimens of crystalline organic thin films which minimizes the mechanical, chemical and thermal load of the organic film during preparation and allows to take TEM images with molecular resolution. A typical example of a thin film of diindenoperylene capped with a thin layer of gold is shown to demonstrate the application of the tech...
