Investigation of passivation processes for HgCdTe/CdS structure for infrared application

The effect of chemical and in-situ electrochemical etching on the morphology of the mercury cadmium telluride (HgCdTe) surface, prior to growth of the cadmium sulfide (CdS) films, has been examined. The CdS films have also been characterized using grazing angle X-ray diffraction and optical absorption spectroscopy. Preferential growth of (002) planes of CdS has been observed on the HgCdTe substrate. The effectiveness of the surface treatment and CdS growth methodology for passivation of the HgCdTe surface has been examined using capacitance–voltage studies of Au/HgCdTe/CdS/Au devices at 77 K. A negative fixed charge density  10¹⁵/m² was obtained.     

Underwater image enhancement using blending of CLAHE and percentile methodologies

In this paper, a method has been proposed for enhancement of underwater images commonly suffering from low contrast and degraded shading quality. The entirety of the image is changed when we move to capture of images, from air to the water. During capturing some absorption, reflection and scattering effects are induced in the form of contrast, quality and noise as the images look hazy or blurred. This makes one shading to overwhelm the image. For use of underwater resources and overcome these factors the enhancement of the images is required. So, in this paper, we proposed a strategy for underwater image enhancement using Contrast-Limited Adaptive Histogram Equalization (CLAHE) and Percentile methodologies. Finally, these two methodologies are blended for improving the outcomes. Two parameters, namely, Root Mean Squared Error (RMSE) and entropy have been considered for comparing the experimental results of the proposed methodology with the state-of-the-art works. It has been noticed that the proposed system performs better than already existing techniques for underwater image enhancement.

Comparison of Quercetin Pharmacokinetics Following Oral Supplementation in Humans

Abstract: The objective of the study was to investigate the absorption of quercetin aglycone in 18 healthy human subjects administered via the following oral carrier systems: suspension of quercetin (quercetin QU995 powder in Tang^® and spring water), nutritional bars (First Strike?), and chews (RealFX? Q‐Plus?). Subjects were divided into 3 groups of 6 individuals each receiving 500 mg quercetin in one of the aforementioned formulations. Blood levels were monitored immediately pre‐ and for 32 h postadministration. The concentration of total quercetin in blood samples was determined by solid phase extraction followed by high‐performance liquid chromatography analysis. Pharmacokinetic parameters were determined by noncompartmental modeling using Kinetica software. The C_max of quercetin was highest with RealFX? Q‐Plus? Chews (1051.9 ± 393.1 μg/L) achieved within 3.3 h as compared to that for First Strike? Bars (698.1 ± 189.5 μg/L in 2.3 h) and Tang^® suspension (354.4 ± 87.6 μg/L in 4.7 h). The results showed no statistically significant difference in quercetin absorption among groups due to high variability within groups receiving quercetin from same dosage form. This study represents the first comprehensive evaluation of quercetin absorption from quercetin fortified oral food products at doses commonly used for quercetin supplementation. Practical Application: The current study describes for the first time, comprehensive evaluation of quercetin PK in humans from quercetin fortified oral food products at doses commonly used for quercetin supplementation. Owing to quercetin's potent antioxidant and anti‐inflammatory actions, quercetin is widely being used as a nutritional supplement. In order to maximize the bioavailability of quercetin for its use in efficacy studies, it is important to determine its ideal oral carrier system and route for its delivery. The current research unveils vital information about quercetin supplementation to the international community, especially to soldiers, athletes, and the dietary supplement industry.
