Low intensity ultrasound (approximately 10(-6) W cm-2) in the frequency range 0.5-6.0 MHz was employed to investigate the ultrasound absorption properties of doxorubicin (DOX) at several temperatures. At physiological temperatures, we found enhanced ultrasound absorption from DOX, and its closely related analogue daunorubicin (DNR), in the upper kilohertz frequency range. The findings do not co...

Steelmaking slag is a by-product of steel making. It has been reused as a material for civil engineering, pavement construction etc. For such applications, it is extremely important to evaluate the amount of free lime, which has the chemical form of calcium monoxide (CaO) and can cause the failure of mechanical properties by volume expansion through absorption of water or carbon dioxide gas. So...

Optical absorption measurements of trace level (ppb) pollutants in ambient air samples and chemical reaction products in laboratory flow reactors have been made using a new technique employing pulsed laser sources. This new technique allows optical absorption measurements to be made using either broad band or narrow band pulsed lasers and offers a temporal resolution and absorption detection se...

the silver nanoparticles are well-known for their antimicrobial, anti-inflammatory wound healing abilities. we synthesized silver nanoparticles using chemical reduction method and the formation of the silver nanoparticles was characterized by uv-vis absorption spectroscopy, ft-ir and sem techniques. the minimum inhibitory concentration of the synthesized nanoparticles was determined for both gr...

We have demonstrated that the relaxometry technique is very efficient to quantify paramagnetic ions during in situ electrolysis measurements. Therefore, the goal of this work was to validate the relaxometry technique in the determination of the concentration of the ions contained in electrolytic solutions, Cu(2+), Ni(2+), Cr(3+), and Mn(2+), and compare it with other analytical methods. Two dif...

This article reports the effective usage of redmud(RM) an industrial waste ,as a  novel filler in polymer matrix. The composite has been fabricated with redmud as secondary reinforcement in banana fiber reinforced polyester (BFRP) using compression molding technique. The mechanical properties such as tensile, flexural and impact strength have been studied for different fiber weight percentage, ...

In the present work, photocatalytic activity of pristine Cu2SnS3 (CTS) and a composite with graphene oxide (GO), i.e., CTS + GO, prepared by precipitation technique, its utilization as catalyst for degradation Navy Blue (NB) ME2RL reactive azo dye were studied. The structural, morphological, optical properties synthesized evaluated. dyes was used to evaluate GO under visible light irradiation. ...

In this Letter, we study the heat dissipated at metal surfaces by the electromagnetic field scattered by isolated subwavelength apertures in metal screens. In contrast to the common belief that the intensity of waves created by local sources should decrease with the distance from the sources, we reveal that the dissipated heat at the surface remains constant over a broad spatial interval. This ...
