An Overview of Trinitrotoluene (TNT)
Abstract: As for TNT, it is also a high explosive. TNT is a yellowish compound with the chemical name trinitrotoluene, which is somewhat easier to remember than its chemical formula, CH 3C6H2(NO2)3. 2,4,6-TRINITROTOLUENE is a 2,4,6-trinitrotoluene, which is an explosive chemical that can cause skin irritation and other toxic consequences. 2,4,6-Trinitrotoluene is a yellow, odorless solid that does not occur naturally in the environment. It is commonly known as TNT and …

Synthesis of White Light Emitting Water-soluble CdZnS Quantum Dots at Room Temperature
Abstract: Water-soluble alloyed CdZnS quantum dots (QDs) have been successfully prepared at room temperatures by reacting a mixture of Cd(CH3COO)2 and Zn(CH3COO)2 with Na2S using thiolactic acid (TLA) as a surface capping agent. The photoluminescence (PL) spectra of the alloyed QDs are determined on the basis of the Cd2+/Zn2+ molar ratio, reaction pH, intrinsic Cd2+and Zn2+reactivities toward Na2S and the concentration of capping agent. A systematic blue shift in emission wavelength …

Enhancing Soil Stabilization with Chitosan Biopolymer Integration
Abstract: In this work, clay soil is stabilized using a biocompatible chitosan solution derived from shrimp shell waste. The biopolymer chitosan has attracted attention in the field of geoenvironmental studies because of its possible applications in the absorption of heavy metals, the mitigation of soil erosion, and the improvement of hydraulic conductivity. However, a thorough investigation into its impact on the mechanical properties of soil has not yet been conducted. A …

Nanotechnology based solutions for control of Agricultural pests
Abstract: Application of nanotechnology for the control of agricultural pests is an emerging field of research. It is driven by the realization that they are more effective and are equally competent in terms of their biocidal potential and that too at significantly low concentrations as compared to conventional pesticides. Unscrupulous application of larger volumes of chemical pesticides has many harmful effects including, acute toxicity to animals and human beings (up on …

Studies of Nano-catalyst
Abstract: Nano-catalysts are studied in this article to compose single allocate transitional or novel atom on substrate in place of usual nano-configured atoms aligned to Pt, Pd, Ru, Rh and Ir. Acid to base proposition subjected to form stable catalyst composes from transition metals in place from expensive novel metals. In novel metal nano-cluster catalyst compose has selected scheme at rest with no or reverse consequence to give rise well defined …

Free Vibration Analysis of Laminated Composite Plate with Various Boundary Condition Using FEM
Abstract: The vibration analysis of laminated composite plates is analyzed using finite element method. A suitable finite element model is proposed and developed based on first order shear deformation theory using ANSYS parametric design language (APDL) code. The model has been developed using an appropriate eight node isoparametric element (SHELL281) from the ANSYS element library. In this paper Numerical results have been computed for the effect of material properties, thickness ratio …

A Review on the Properties of Polymeric Micelles
Abstract: Lately, polymeric micelles have pulled in a considerable measure of consideration as far as their particular conveyance of hydrophobic payload to the objective site. Polymeric micelles are viewed as more steady than their surfactant partners and can drag out flow times in vivo and their particular gathering in the tumoral tissues. They can viably solubilize little hydrophobic medications in their internal most hydrophobic center while their external hydrophilic shell can …

Experimental Investigation of Three Pass Helical Coil Heat Exchanger Keeping Constant Mass Flow Rate of Tube Fluid
Abstract: Heat exchanger is an adiabatic steady flow, open system in which two flowing fluid exchange or transfer heat without loosing or gaining any to the ambient. Heat exchangers are the important engineering systems with vast variety of applications including power generation, heating ventilation and air conditioning systems, nuclear, heat recovery systems, food and paper industries and many more. Helical coil structure configuration is very effective for heat exchangers because it …
