Experimental hydrothermal geochemistry has made great strides on the basis of stoichiometric equilibrium studies, measured kinetic rates, and bulk-sensitive spectroscopic data, but there are current problems in hydrothermal geochemistry ranging from deep aquifer chemistry to nuclear waste tank chemistry that can benefit from new techniques able to provide direct spectroscopic and microscopic in...

In this study, the hydrothermal treatment of municipal solid wastes (MSWs) for the production of biochar as a renewable solid fuel was investigated. The properties of surrogate MSWs and mixtures of newspaper and vegetables were greatly improved by hydrothermal treatment and were similar to those of coal-like fuel substances. Hydrothermal treatment increased the calorific value, the fixed carbon...

the importance of dietary fiber in normal and therapeutic diets has been acknowledged by numerous authors in recent years. dietary fiber has different physiological effects on human health. the recommended daily intake of dietary fiber is about 30 g, but less than this is often consumed. wheat bran is an excellent source of dietary fiber and is used to fortify foods. the nutritional benefits of...

W/Cu joining is key for the fabrication of plasma-facing compounds fusion reactors. In this work, W and Cu are joined through three steps: (1) hydrothermal treatment reduction annealing (i.e., nano-treatment), (2) plating in a pure H2 atmosphere, (3) bonding at 980 °C 3 h. After nano-treatment, nanosheets structure can be found on substrate surface. The tensile strength joint prepared via nano-...

The spectral and spatial properties of the advanced spaceborne thermal emission and reflection radiometer (ASTER) data can be used in detailed lithological and hydrothermal alteration mapping related to copper and gold mineralization, particularly the shortwave infrared radiation subsystem where hydrothermal alteration minerals have diagnostic spectral absorption features. This paper reviews th...

An efficient asymmetric synthesis of cyclo-archaeol and β-glucosyl cyclo-archaeol is presented employing catalytic asymmetric conjugate addition and catalytic epoxide ring opening as the key steps. Their occurrence in deep sea hydrothermal vents has been confirmed by chromatographic comparison with natural samples.
