Abstract Thermo-anodization technology has been considered as an effective means to improve the thermal, physical and chemical properties for metal alloy. In this work, we achieve a porous black layer on surface of aluminium alloy through environmentally friendly anodic oxidation process, with high thermal emittance (0.96) solar absorptivity (0.921). addition, thermo-anodized coating shows uniq...

A general framework for the thermodynamics of open systems is presented. The theory is fundamentally based on the generalized balance of mass, which is enhanced by additional surface-°ux and volume-source terms. The presentation highlights the in°uence of the enhanced mass balance on the remaining balance equations. To clarify the impact of the variable reference density, we introduce the notio...

The ablation of ultra-high-temperature ceramics (UTHCs) is a complex physicochemical process including mechanical behavior, temperature effect, and chemical reactions. In order to realize the structural optimization functional design ultra-high ceramics, coupled thermo-chemomechanical bond-based peridynamics (PD) model proposed based on ZrB2 oxidation kinetics thermomechanical peridy...

The studies include the results and discussion related with reaction of Fe2O3 with Na2SO4 in presence of SO2 (g) at 800 and 900 C. The iron oxides are produced by the oxidation of iron base alloys in many industrial operations. The metal oxide undergoes certain high temperature chemical reactions in presence of a gas (such as SO2) and molten salts (say Na2SO4). The thermo-gravimetric studies h...

Sampling of monoterpenes from air on the Tenax porous polymer may introduce analytical errors owing to oxidation and acid rearrangements on the adsorbent. Particularly terpenes which react rapidly with ozone, e.g. myrcene and limonene, are partially lost when sampling air with high photooxidant levels. On acidified adsorption cartridges, a-pinene and ~-pinene may be converted to camphene, limon...

the methylotrophic thermo tolerant actinomycete strain 381, was isolated from a compost sample, assimilated methanol during growth. methanol dehydrogenase could not be detected in cell extracts using dye-linked assays in the absence of nad+. dichlorophenol-indophenol-linked methanol oxidation was detected in broken cell suspensions in the presence of nad+ and the absence of cyanide. taxonomic s...

Protein oxidation within cells exposed to oxidative free radicals has been reported to occur in an uninhibited manner with both hydroxyl and peroxyl radicals. In contrast, THP-1 cells exposed to peroxyl radicals (ROO(*)) generated by thermo decomposition of the azo compound AAPH showed a distinct lag phase of at least 6 h, during which time no protein oxidation or cell death was observed. Gluta...
