diamond like carbon (dlc) film was grown by hot filament chemical vapor deposition (hfcvd)technique. in the present work, we investigated the quality of the dlc films groew on the substratesthat were coated with various metal nanocatalysts (au and ni). a combination of ch4/ar/h2 rendersthe growth of carbon nanostructures technique (diamond like carbon). the utilized samples werecharacterized by...

the persian gulf is northern part of the ropme sea area (rsa), and is semi-enclosed shallow sea which located in subtropical climate. measuring is 1000km in length, varying in width 60-340km, and average depth is about 35m and maximum depth is 105m. this research was carried out during 2005-2010 for reviewing the corals status and determination of coral reef habitats distribution in the persian...

Green fluorescent protein (GFP)-like pigments have been proposed to have beneficial effects on coral photobiology. Here, we investigated the relationships between green fluorescence, coral heating and tissue optics for the massive coral Dipsastraea sp. (previously Favia sp.). We used microsensors to measure tissue scalar irradiance and temperature along with hyperspectral imaging and combined i...

Climate change-driven coral disease outbreaks have led to widespread declines in coral populations. Early work on coral genomics established that corals have a complex innate immune system, and whole-transcriptome gene expression studies have revealed mechanisms by which the coral immune system responds to stress and disease. The present investigation expands bioinformatic data available to stu...

The unanticipated impacts of consumers in fragmented habitats are frequently a challenge for ecosystem management. On Indo-Pacific coral reefs, crown-of-thorns sea stars (Acanthaster spp.) are coral predators whose outbreaks cause precipitous coral decline. Across large spatial scales, Acanthaster densities are lower in large no-take Marine Protected Areas (MPAs) and reefs subject to limited hu...

A high working temperature of the ZnO nanomaterial-based gas sensor could shorten lifetime and increase its power consumption. Enhancing volatile organic compound (VOC) sensing performance sensors in terms response is vital for their practical application. Decoration noble metals onto nanostructures an effective approach improving characteristics. Herein, hydrothermally synthesized coral-like n...

In this research, we developed a facile method for the synthesis of silver chloride: polypyrrole (AgCl: PPy) nanocomposites with enhanced structural, thermal, optical, and conducting properties. Polypyrrole monomer was in-situ doped varying weight percentages assynthesized Ag nanoparticles by following simple chemical oxidation polymerization technique to form AgCl: PPy nanocomposites. The AgCl...

The coral holobiont is the integrated assemblage of the coral animal, its symbiotic algae, protists, fungi and a diverse consortium of Bacteria and Archaea. Corals are a model system for the study of symbiosis, the breakdown of which can result in disease and mortality. Little is known, however, about viruses that infect corals and their symbionts. Here we present metagenomic analyses of the vi...
