Ethylene oxide (EtO) is a key carcinogen that widely used in chemical manufacturing and biotechnology industries. Recent work has suggested permissible exposure limits for EtO be reduced from 1–5 ppm to sub-ppb levels. Such new standards will require methodologies are capable of measuring with the requisite precision. In this paper, we demonstrate analyzer based on cavity-enhanced absorption sp...

Recently, the use of superparamagnetic iron oxide nanoparticles (SPIONS) as a new and promising source of iron in agriculture has been suggested that further investigation is needed before extensive field use. In a greenhouse experiment, the effect of coated magnetite nanoparticles with humic acid (Fe3O4/HA NPs) was investigated on iron deficiency chlorosis and photosynthesis efficiency compare...

Agave fibers (AF) were incorporated either pristine (AFp) or surface treated by ethylene plasma (AFm) in low-density polyethylene (LDPE)/ethylene vinyl acetate (EVA) blends at a ratio of 1 : and foamed chemical means. The role the AF content (3, 6, 9, 12, 15 wt.%) its modification on cellular morphology mechanical properties LDPE/EVA/AF foams under compression is investigated herein. Fourier tr...

This paper experimentally studies the heat absorption performance of a heat sink with vertical embedded heat pipes in the aluminum blade. The cooling system with embedded heat pipes distributes heat from the CPU to both the base plate and the heat pipes, and then transfer heat from fins to the Environment. The thermal resistance and heat transfer coefficient are evaluated for natural convection...

New cation deficient tetragonal scheelites, (Sr,Ce)nWO4 (n ​< ​1) were synthesized using the Ethylene-DiamineTetraacetic Acid-citrate method. The chemical compositions and homogeneity of powders determined by Energy Dispersive Spectroscopy. Whatever cerium amount, scheelites exhibit (3 ​+ ​2)D incommensurate modulations, which evolve with structural cations vacancies amount. optical absorption ...

The process of ethylene production from ethane dehydrogenation is one of the interesting processes in the field of conversion the petroleum light gases to the valuable products. In this process, the outlet gaseous product is a combination of ethylene, ethane and hydrogen. Effective separation techniques are required for separation of ethylene from unreacted ethane. Here a new adsorbent approach...

vacuolation. The Purkinje cells were severely damaged and the endothelial lining of some of the cerebral blood vessels was swollen and had separated from the surrounding tissues. Neither ethylene chlorohydrin, nor chloracetic acid were found on toxicological examination of the blood and tissues. Discussion No descriptions are available of the effects in humans after drinking ethylene chlorohydr...

A low-cost Transition Temperature Mixture (TTM) has been synthesized by mixing ethylene glycol and potassium hydroxide as a new non-aqueous CO2 sorbent. Boric acid added to ensure the reversibility of system small amount water modulate viscosity optimize performances. The resulting mixtures have characterized in terms viscosity, conductivity density over temperature (therefore ionicity via Wald...
