Estudo da Influência do Tempo de Síntese na Obtenção de Hidroxiapatita por Hidrotermal/micro-ondas

Orbital: The Electronic Journal of Chemistry, 2014
The hydrothermal system has been widely used in recent years for the synthesis of materials, especially in the synthesis of nanostructured materials. The present work aimed to synthesize hydroxyapatite, since it is characterized by being a biomaterial ...

An Examination of the Cs2NaInCl6 Luminescence: Interplay of Self‐Generated In+ and Doped Sb3+, Er3+/Yb3+ Ions

Advanced Optical Materials, EarlyView.
A new luminescence mechanism in Cs2NaInCl₆ is revealed through spontaneously formed In3+→In+ centers and Er3+/Yb3+/Sb3+ doping. Tunable visible, near‐infrared, downconversion, and upconversion emissions are demonstrated, while DFT calculations explain the electronic structure.

Diversity of meiofauna at deep-sea hydrothermal vents and cold seeps with particular reference to nematodes

, 2007
Deep-sea hydrothermal vents and cold seeps are remarkable for their spectacular megaandmacrofauna, many of which appear to have a high level of endemism to these chemosyntheticenvironments.

Seeps and Tectonic Structure of the Hydrothermal System of the Panarea Volcanic Complex (Aeolian Islands, Tyrrhenian Sea)

Geosciences
High-definition bathymetry mapping, combined with the measurement of dissolved benthic fluxes and water column biogeochemical properties, allows for a description of new biogeochemical processes around the Panarea Volcanic island.

Exploitation of Vigorous Hydrothermal Systems

Energy Exploration & Exploitation, 1982
Some 1% of the earth's crust has heat flux significantly above the global average. Concentrated in areas of the order of 10km 2 associated with volcanic zones, such energy can be tapped for local power projects commonly generating 10MW km 2 .

Hydrothermal sediments record changes in deep water oxygen content in the SE Pacific

, 2010
The distribution of redox?sensitive metals in sediments is potentially a proxy for past ocean ventilation and productivity, but deconvolving these two major controls has proved difficult to date.

Short‐ and Long‐Term Seismic Velocity Variations and Strain Evolution at Ischia (Italy): Implications for Dynamics of the Hydrothermal System

Geophysical Research Letters
In active volcanic systems, the elevated pressurization of fluids and the movement of molten materials influence the stress state and mechanical behavior of rocks, but the direct measurement of these processes and the related evolution of rocks ...

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation

Advanced Science, EarlyView.
A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.
