To improve the impedance matching condition and broaden effective absorbing bandwidth, a series of cylindrical periodic structured gypsum composites with different kinds carbonaceous materials as absorbents were fabricated by two-step molding process. The influences mass fraction helical carbon fiber (HCF), nanotube (CNT), graphene (GE) on morphology, permittivity, resistivity, electromagnetic ...

introduction the occurrence of mycotoxins in foods and feeds is a problem of major concern in all over the world. profitability of poultry production can be greatly affected due to the frequency of feed contamination and the detrimental effects of these toxins on the performance. aflatoxins, a group of closely related and biologically active mycotoxins, are produced by strains of aspergillus fl...

Standard dialyzer membranes, designed for diffusive clearance, do not effectively clear protein-bound uremic toxins, such as indoxyl sulfate (IS). To increase toxins removal, absorbents require a high specific surface area to achieve effective size-coupling removal of target toxins. However, the toxicity molecule is necessarily determined by size alone. As proof concept, we report on an electro...

Increasing concerns about the atmospheric CO2 concentration and its impact on the environment are motivating researchers to discover new materials and technologies for efficient CO2 capture and conversion. Here, we report a study of the adsorption of CO2, CH4, and H2 on boron nitride (BN) nanosheets and nanotubes (NTs) with different charge states. The results show that the process of CO2 captu...

During long-term low-flow sevoflurane anesthesia, dew formation and the generation of compound A are increased in the anesthesia circuit because of elevated soda lime temperature. The object of this study was to develop a novel radiator for carbon dioxide absorbents used for long durations of low-flow sevoflurane anesthesia. Eleven female swine were divided into two groups comprising a "radiato...

A study to determine the structure and activity relationships of various amine based CO2 absorbents was performed in which, the desorption of CO2 from saturated absorbent at 80 C and atmospheric pressure was measured to assess the initial desorption rate and desorption capacities at pseudo equilibrium. Evaluation of desorption capacity at 80 C will give a better understanding for more energy ef...
