Wanted – $48 Trillion to Meet World Energy Needs to 2035

by GLOBE Foundation  (Jun. 3, 2014)

Meeting the world’s growing need for energy will require more than $48 trillion in investment over the period to 2035, according to a special report on investment released today by the International Energy Agency (IEA) as part of the World Energy Outlook series. Today’s annual investment in energy ...

FTIR analyser improves anaesthetic gas detection at Torbay Hospital

by Gasmet Technologies Oy  (Dec. 10, 2013)

A unique gas measurement technology has enabled South Devon Healthcare’s Pharmacy Manufacturing Unit (PMU) at Torbay Hospital to conduct highly effective and detailed analysis of anaesthetic gases in a variety of hospital locations. The primary function of the PMU’s quality control department is to check active ingredient levels and ...

Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

by Gasmet Technologies Oy  (Apr. 16, 2014)

Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse ...

Preparation of carboxymethyl-quaternized oligochitosan and its scale inhibition and antibacterial activity

by IWA Publishing  (May 28, 2014)

Carboxymethyl-quaternized oligochitosan (CMQAOC) was prepared through carboxymethylization and N-quaternization of oligochitosan (OC) which was obtained from chitosan degradation. The structure was confirmed by Fourier transform infrared spectroscopy (FT-IR), 1H-NMR, and X-ray diffraction (XRD) analysis. The performances for both scale and ...

Effects of pH on chromate(VI) adsorption by Spirulina platensis biomass: batch tests and FT-IR studies

by IWA Publishing  (May 9, 2013)

Raw and methylated biomass of Spirulina platensis was employed in chromate batch adsorption tests at pH range 1–7. The acid conditions seemed to favour the removal of chromium (Cr) with a yield of 87.0 and 97.6% by using raw and methylated biomass, respectively. However, the chromate and total chromium determination, carried out in ...

Change of surface and structure properties of cation exchange membrane in a microbial fuel cell

by Inderscience Publishers  (May 27, 2014)

In this study, the two–chambered microbial fuel cell (MFC) was continuously long–term operated a young landfill leachate in order to evaluate the impact of cation exchange membrane (CEM) fouling on MFC performance. During the operation, the voltage output decreased sharply to almost zero and the voltage output was recovered completely after ...

FTIR gas analysis improves container safety

by Gasmet Technologies Oy  (Feb. 22, 2013)

Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of ...

Application of amine–functionalised nano SBA–15 for removal of bichromate from aqueous solutions

by Inderscience Publishers  (Mar. 20, 2014)

In this research, molecular sieve SBA–15 was synthesised and functionalised with 3–aminopropyltrimethoxysilane (N–silane) and [1–(2–aminoethyl)–3–aminopropyl] trimethoxysilane (NN–silane). The materials were characterised by X–ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectrometry (FT–IR), and ...

FTIR resolution requirements for industrial gas analyses

by CIC Photonics, Inc.  (May 1, 2013)

FTIR Spectroscopy FTIR Spectroscopy is a widely used technique for gas analyses in industrial applications. It is a technique used in the semiconductor industry for measuring the purity of cleaning, etching, and epitreatment gases used with various process tools, reactors, and abatement devices. Among chemical companies and R&D faciltities, ...

Comparative in situ PET biodegradation assay using indigenously developed consortia

by Inderscience Publishers  (Apr. 24, 2014)

A soil burial test was carried out to evaluate the biodegradation of polyethylene terephthalate under natural environment for a period of six months in presence of three different indigenously developed bacterial consortia. These consortia comprised of potential polymer-degrading bacterial cultures isolated from various waste disposal sites. The ...
