In order to study the hydrothermal behavior of cotton fiber, the carbonization process and structural evolution of discarded cotton fiber (WCF) under hydrothermal conditions were discussed use microcrystalline cellulose (MCC) and glucose as model compounds. The results showed that high temperature was beneficial to the hydrolysis of discarded cotton fiber, and the yield of the sugar was 4.5% wh...

Increased vascular calcification and tortuosity are rather common in end-stage renal failure patients who are on hemodialysis. It renders manipulation of catheters and performance of percutaneous transluminal interventions more difficult than expected. Such vascular alterations may be evident in large veins and pose significant difficulties in placement of pacing leads as shown in our case. To ...

The poor hydrothermal stability of germanosilicate zeolites greatly retards their industrial application. Herein, we present a direct synthesis of Ge-containing IWR zeolites with outstanding hydrothermal stability. A simple quaternary ammonium cation, diethyldimethylammonium, was used as the structure-directing agent for the first time. The structure and chemical composition of the framework wa...

The present paper presents a facile and low-cost hydrothermal method to synthesize stoichiometric FeNi3 alloy nanoparticles by reducing Ni(NO3)2.6H(2)O and Fe(NO3)2.9H(2)O with hydrazine hydrate in strong alkaline media. X-ray diffraction patterns of as-prepared samples synthesized at 180 degrees C for different hydrothermal reaction times reveal that the products are pure stoichiometric FeNi3 ...

The operation planning of hydrothermal systems aims to specify how the set of power plants should be operated so that the resources available for power generation are used efficiently. In hydrothermal systems with great participation of hydroelectric generation, as is the case of the Brazilian system, the operation planning intends to establish Reservoir Operation Rules (RORs) to replace, whene...

Bacillus alveayuensis strain 24KAM51 was isolated from a marine hydrothermal vent in Milos, Greece. Its genome depicts interesting features of halotolerance and resistance to heavy metals.

Lake Baikal is the deepest, oldest and most speciose ancient lake in the world. The lake is characterized by high levels of molluscan species richness and endemicity, including the limpet family Acroloxidae with 25 endemic species. Members of this group generally inhabit the littoral zone, but have been recently found in the abyssal zone at hydrothermal vents and oil-seeps. Here, we use mitocho...

Hyperspectral remote sensing records reflectance or emittance data in a large sum of contiguous and narrow spectral bands, and thus has many information in detecting and mapping the mineral zones. On the other hand, the geological and geophysical data gives us some other fruitful information about the physical characteristics of soil and minerals that have been recorded from the surface. ...

The Ediacaran Dengying Formation in Central Sichuan Basin is the deep dolomite gas reservoir with largest natural reserves China, providing an excellent example for understanding effect of diagenesis evolution on quality. By integrating petrology, geochemistry and situ U-Pb dating, this study aims to reveal genesis different rock fabrics their corresponding diagenetic events, discuss temporal r...
