Maghemite and magnetite nanoparticles and nanorode are now losing interests in the field of nanobiotechnology and pharmaceutical for their applications. This paper reports on a hydrothermal process for the synthesis of Fe2 O3 in the γ-phases nanorodes, when the hydrothermal temperature was 100 ̊ C. The uniqueness of the method lies in the use of ferrous ammonium sulphate, hexamine was added as t...

How did life originate on Earth? This has always been a challenging topic generating continuous interest among different fields, such as chemistry, biology, physics, and engineering. The “primordial soup”, which has been the most commonly accepted theory, fails to explain how molecules present at low concentrations in the prebiotic oceans could create the building blocks of life, such as protei...

Cryptococcus sp. strain Mo29 was isolated from the Rainbow hydrothermal site on the Mid-Atlantic Ridge. Here, we present the draft genome sequence of this basidiomycetous yeast strain, which has highlighted its biotechnological potential as revealed by the presence of genes involved in the synthesis of secondary metabolites and biotechnologically important enzymes.

Large scale synthesis of uniform self-assembly Fe(3)O(4)@phenol formaldehyde resin (PFR) core-shell nanowires with 80-100 nm in diameter and 20-30 microm in length can be realized by a one-pot hydrothermal process. The optical and magnetic properties of the as-synthesized Fe(3)O(4) nanostructures have been investigated.

Hexagonal nanoflower WO3 arrays have been prepared by using RCOO(-) as the structure directing agent in the microwave-assisted hydrothermal synthesis process. The photoelectrochemical performance of the synthesized hexagonal flower-like WO3 electrode was enhanced compared with the block-like WO3 film.

The origin of life is still an unsolved mystery in science. Hypothetically, prebiotic chemistry and the formation of protocells may have evolved in the hydrothermal environment of tectonic fault zones in the upper continental crust, an environment where sensitive molecules are protected against degradation induced e.g. by UV radiation. The composition of fluid inclusions in minerals such as qua...

A specific control of the morphology and chemical structure of hydrothermal carbon (HTC) is of crucial importance for its application, both in catalyst supports or electrochemical devices. Here we show how the morphology, that is, particles size and homogeneity, and the distribution of functional groups can be controlled by the control of the synthesis pH of the hydrothermal carbonization. A co...

In this research, a single-stage low-temperature hydrothermal synthesis route was successfully developed for preparation of Iron Disulfide. The prepared powder was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). These analyses showed that nanoparticles were well crystallized, pyrite was the main product and the shape of crystals was nanorod. Also, the influences...

A sustainable, sugar-based hydrothermal synthesis generates highly entangled, yet controlled porous carbonaceous frameworks via interdigitation and twisting of layered phases.
