In this research, the occurrences of antimicrobial activity of some ferns were studied. The present paper dealt with the antimicrobial activities of some ethno-medicinally important ferns which were very common in West Mednapore District, as well as South West Bengal, against gram-positive and gramnegative bacterial pathogens. The plants were extracted with different solvents (70% ethanol, meth...

We investigated the effects of hygrothermal aging on the tension–tension fatigue behavior of unidirectional (UD) glass/polydicyclopentadiene (pDCPD) composites. Samples were immersed in deionized (DI) water and salt water, and glass/epoxy composites were used as a benchmark for comparison. Composites of pDCPD showed less water uptake and superior fatigue performance compared to similarly aged e...

The electro-spraying process can be regular and periodic, consisting of cyclical phases of initiation (meniscus, drop, and/or jet), pulsation, deformation and separation. This paper presents an experimental study on the repetition frequency of drop and/or jet ejection from the capillary end with various spraying modes during an electro-spraying process of deionized (DI) water. The influence of ...

For successful commercial adaptation of the l-EDM (micro electro-discharge machining) process, there is a need to increase the process efficiency by understanding the process mechanism. This paper presents a model of the plasma discharge phase of a single discharge l-EDM event in deionized water. The plasma discharge is modeled using global model approach in which the plasma is assumed to be sp...

Materials Lambda exonuclease ( exo), Exonuclease I (exo I), Lambda Exonuclease Buffer and ThermoPolReaction Buffer were all purchased from New England Biolabs (MA, USA). Taq DNA polymerase was purchased from Tiangen Biotech Co. (Beijing, China). DNA strands were synthesized and purified by HPLC (Sangon Co., China). The sequences of all the probes and targets that have been studied in this work...

We have developed a novel carbon nanotube-based contrast agent for both thermoacoustic and photoacoustic tomography. In comparison to deionized water, single-walled carbon nanotubes exhibited more than twofold signal enhancement for thermoacoustic tomography at 3 GHz. In comparison to blood, they exhibited more than sixfold signal enhancement for photoacoustic tomography at 1064 nm wavelength. ...

BSA solutions of 10 %, 1 % and 0.1 % were prepared by addition of lyophilized BSA powder (Sigma Aldrich, St Louis, MO, USA) into deionized water before being filtered through a glass fiber filter (Whatman GF/F) under vacuum in order to remove particles that can clog the system. Tween 80 was then added to a obtain 0.05 % [V/V] solution. The BSA solutions were then refrigerated before use. All so...

Water solutions with electrical conductivities ranging from that of the deionized water up to 2 S/m have been electrosprayed in air through narrow silica tubes. Results show unambiguously that steady cone jets of water in air without the assistance of glow discharge can be formed for the range of electrical conductivities we have explored. The absence of corona discharge has been proven not onl...
