Introduction

The conversion of gas into liquid fuels is an innovative technology that is well-known to many people. This technique is so promising and enhancing new options for environmentally friendly manufacturing of fuels and chemicals as well as other natural gases. Looking into the large natural gas and coal reserves and deteriorating petroleum reserves all over the world, it is anticipated to play an important role in the future. Cobalt-based chemical agents are the ideal catalysts for hydrogen synthesis since they have a high FTS functionality, discernment for long-chain paraffin as well as a low process for the water-gas change ...

Carbon dioxide is an odorless, non-combustible gas that could be both beneficial and threatening to the environment. This gas is inherently part of the earth’s biogeochemical cycle and is as equally important as other naturally occurring gases in the earth’s atmosphere. While carbon dioxide provides benefits to plants via photosynthesis, its effect on the atmosphere at high levels may induce modifications in the naturally occurring changes in climate all over the world. To date, carbon dioxide has been put into a spotlight as the main cause of anthropogenic climate change. Anthropogenic emissions of carbon dioxide (CO2) have ...

Analytical methods to evaluate seed dormancy in legumes

Abstract Legumes are known to have multiple health benefits. The seed coat in particular contains a number of bioactive compounds which possess antioxidant activity. Of great interest is the relationship between the chemical composition of the seed coat and its role in seed dormancy. Modern technological approaches are currently used to further identify these compounds and determine their role in seed development; these include NRIS FTIR, mass spectroscopy, electron microscopy and chromatography. The following review describes the constituents of the legume seed coat and their respective roles in dormancy and other stages of seed development. The review also highlights ...

Investigating the Functions of Proteins

The steps made so far in the process of gene mapping has opened up ways in which more studies are done on the human DNA. ENCODE and Genome researchers have so far sequenced more than 90 genomes. With the understanding of genes and their loci, it has been easier to locate and carry out studies on a single gene. Most genes code for various proteins in the body of an organism; it has become paramount that the roles of these genes be identified and prescribed out. The knowledge of the functions of each gene, or the protein it codes for, ...

Over the last few years, technologies such as Mass Spectrometry Imaging (MSI) have increasingly grown in potential as new tools in the plant sciences (1). In particular, Matrix-Assisted Laser Desorption/Ionisation (MALDI) mass spectrometry imaging using the power of high mass resolution time of flight (ToF) mass spectrometry can offer new information regarding the spatial distribution of specific molecules within biological tissues (2). Together with advances in other technologies such as nuclear magnetic resonance (NMR), metabolites can be identified and quantified within specific cell types of plants and other organisms, and this can greatly expand fields ranging from proteomics and ...

Abstract

Knowledge on phase equilibrium behavior plays a central role in the prediction of the solubility of the components found in biodiesel. This aids in the separation process of the individual components. These components are normally referred to as volatile organic compounds. It is crucial to use models in the determination of these equilibriums since actual measurements are costly and lingering. There are several types of biodiesels: methyl oleate, ethyl stearate, and methyl linolenate. UNIFAV procedure can be used in the determination of of an estimate of the infinite dilution activity of several volatile organic compounds in biodiesels. A mole ...

1. ABSRACT

The purpose of this experiment was two-fold. Firstly it was to synthesize shape-controllable Copper Oxide (Cu2O) under alkaline conditions by using hydrothermal methodology. Secondly it was to measure and evaluate its application for photocatalytic degradation of direct blue dye 53 also commonly known as Direct Blue 53 or Evans Blue. Materials used for the first step were Cu2O and the two reactants, CuCl2.2H2O and NaOH. The temperature during the hydrothermal process was raised from 80°C to 140°C. Two products were synthesized: a) the Cu2O nanorod and b) a mixture of Cu2O nanorod and Cu2O nanocubes.

Hydrothermal temperature was found to ...
