Discrimination of breast cancer from benign tumours using Raman spectroscopy
(
Public Library of Science
, 2019 , Article)
Breast cancer is the most common cancer among women worldwide, with an estimated 1.7 million cases and 522,000 deaths in 2012. Breast cancer is diagnosed by histopathological examination of breast biopsy material but this ...
Catalytic Degradation of 4-Ethylpyridine in Water by Heterogeneous Photo-Fenton Process
(
MDPI
, 2019 , Article)
In this work, the degradation of 4-ethylpyridine (4EP) in water by a heterogeneous photo-Fenton process (H2O2/Fe3O4/ultraviolet irradiation (UV)) was investigated. More rapid and effective 4EP degradation was obtained with ...
Sub-Femtojoule Hybrid Plasmonic Optical Modulator
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
A highly compact optical modulator is proposed and analyzed. The modulator is based on the hybrid plasmonic waveguide platform. The structure of the modulator is built from silicon, silver, and electro-optical polymer ...
CMOS compatible silicon slot ring resonator sensor
(
SPIE
, 2019 , Conference Paper)
We propose a fully CMOS compatible optical sensor based on the ring resonator mechanism. The waveguide structure of the sensor utilizes the silicon on insulator slot waveguide configuration. The analyte fills the slot and ...
Curcumin a Colorimetric and Fluorimetric Cyanide Probe in Aqueous System and Living Cells
(
Royal Society of Chemistry
, 2019 , Article)
Curcumin, 1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-hepta-diene-3,5-dione, is a natural product obtained from the rhizome of Curcuma longa. Curcumin has been demonstrated to be a strong antioxidant with anticancer properties ...
Investigation of Biochemical Alterations in Ischemic Stroke Using Fourier Transform Infrared Imaging Spectroscopy-A Preliminary Study.
(
MDPI
, 2019 , Article)
Brain damage, long-term disability and death are the dreadful consequences of ischemic stroke. It causes imbalance in the biochemical constituents that distorts the brain dynamics. Understanding the sub-cellular alterations ...
The electronic origin of the ground state spectral features and excited state deactivation in cycloalkanones: the role of intermolecular H-bonding in neat and binary mixtures of solvents
(
NLM (Medline)
, 2019 , Article)
In this study, a D-A cycloalkanone (K1) has been investigated by steady state absorption and fluorescence in neat solvents and in three binary mixtures of nonpolar aprotic/polar protic, polar aprotic/polar protic, and polar ...
Synthesis, physico-chemical, hirschfield surface and DFT/B3LYP calculation of two new hexahydropyrimidine heterocyclic compounds
(
Iranian Institute of Research and Development in Chemical Industries
, 2019 , Article)
Two new hexahydropyrimidine compounds were prepared in high yield by condensation of an equimolar amount of 1,3-diamine with 2-dipyridylketone at room temperature in dichloromethane. The desired hexahydropyrimidine structures ...
Secretory laccase from pestalotiopsis species CDBT-F-G1 fungal strain isolated from high altitude: Optimization of its production and characterization
(
MDPI AG
, 2019 , Article)
Microorganisms producing laccases may be used for the pretreatment of lignocellulosic biomass to recover fermentable sugar. Very few fungi and other microbes growing in high altitudes have been tested for this purpose. As ...
Recycling of Date Pits Into a Green Adsorbent for Removal of Heavy Metals: A Fractional Factorial Design-Based Approach
(
Frontiers Media S.A.
, 2019 , Article)
Date pits (DPs) have been recycled into a low-cost adsorbent for removing of selected heavy metals (HMs) from artificially contaminated aqueous solutions. Adsorption of targeted HMs, both by raw date pits (RDP) and burnt ...
