The photocatalytic pretreatment of lignocellulosic biomass to oxidize lignin and increase stability has gained attention during the last few years. Conventional methods are limited by fact that they expensive, non-renewable contaminate anaerobic digestate later on. present study was focused develop a metal-derived photocatalyst can work with visible electromagnetic spectra light commercial liqu...

In this study, the effects of nanosecond plasma discharges on combustion characteristics ammonia are investigated over a wide range mixture properties and settings. The results reveal that impacts change non-monotonically by altering reduced electric field value. Within studied field, i.e., 100–700 Td, it is shown most effective in medium range, e.g., 250–400 Td. At lower values, main fraction ...

Self-healing is achieved with a dual-microcapsule system utilizing epoxy-amine chemistry in a high temperature cured thermosetting epoxy polymer. One capsule contains a modified aliphatic polyamine prepared by vacuum infiltration of polyoxypropylenetriamine into hollow polymeric microcapsules. The second capsule contains a difunctional epoxide and reactive diluent. Healing efficiency is accesse...

Blood can form a gel when there are high concentrations of proteins, such as IgM and/or IgG antibodies, that precipitate at low temperatures (cryoglobulins) or agglutinate red blood cells (cold agglutinins) (1, 2 ). A bone marrow biopsy performed on this patient revealed Waldenström macroglobulinemia, which produces large amounts of IgM (3, 4). Warming this patient’s sample in a water bath, kee...

The term ’carry-over’ is commonly used to describe a process by which materials are carried into a reaction mixture to which they do not belong. These materials can be either parts of a specimen or reagents, including diluent or wash solution. In such cases carry-over means transfer of material (specimen or reagents) from one container or from one reaction mixture to another; it can be either u...

A method is presented for determining erythrocyte sodium and potassium concentration. Heparinized whole blood is separated into cellular and plasma fractions in large-bore capillary tubes. An aliquot of the erythrocyte fraction is then pipetted directly into lithium chloride diluent and the electrolytes determined flame photometrically. Plasma trapping is measured with ‘4C-inulin and correction...

The effect of two acids (phosphoric and acetic) and their derivatives (hydrogen di(2-ethylhexyl)orthophosphoric, chloroacetic, dichloroacetic, trichloroacetic, and trifluoroacetic acids) on the retention of selected alkaloids on silica gel plates has been investigated. The dependence of the chromatographic behaviour of the alkaloids on mobile phase diluent and on the concentration of the acids ...

Ta2O5 films of 10-150 nm thickness were prepared by oxygen-assisted pyrolytic LPCVD at 450-490°C from tantalum penta ethoxide and 0 2 with N2 diluent. Silicon wafers 150 mm in diameter were used as substrates with a novel LPCVD reactor. The films were annealed in dry 0 2 a t 700-800°C. Compositional, structural, and electrical evaluations demonstrate that these uniform, pure, and conformal Ta2O...
