The aim of this paper is to review some of the economic drivers of large scale bioregionalisation, using examples from deep sea hydrothermal vent communities, the Antarctic and sub-Antarctic, and Australia. These economic drivers are mainly recent conservation efforts, while early 20th century bioregionalisation was driven by 19th century taxonomy and exploration to assess available biological ...

In the present study, the effect of alumina on the pore structure and hydrothermal stability of nanostructured silica was investigated. SiO2 and SiO2-15wt%Al2O3 membranes were prepared by dip coating on mesoporous γ-Al2O3 coated macroporous α-alumina support. The particle sizes of sol were increased by adding of alumina to silica...

The diverse applications of ordered mesoporous carbons (OMCs) are not only bonded to their superior structural properties, but also to their chemical properties. The termination of graphene sheets in OMCs provides abundant sites for heteroatom decoration to mediate their chemical properties. In this contribution, boron and phosphorus were co-incorporated into OMCs via a facile aqueous selfassem...

Clean water is an essential resource for life, and its demand continuously increasing with the rapid growth in population, while freshwater reserves are also depleting. A large amount of wastewater released by different industries, which affecting environment as well polluting reserves. Recycling treatment highly to meet clean protect environment. Activated carbon can be used primary, secondary...

11 12 Abstract Nanorods and nanoplates of Y2O3:Eu 3+ powders 13 were synthesized through the thermal decomposition of the 14 Y(OH)3 precursors using a microwave-hydrothermal meth15 od in a very short reaction time. These powders were 16 analyzed by X-ray diffraction, field emission scanning 17 electron microscopy, Fourrier transform Raman, as well as 18 photoluminescence measurements. Based on ...

The effect of the neutral surfactant dodecylamine and octadecylamine on the synthesis of TiO2-based nanostructures by the treatment of anatase with NaOH under hydrothermal conditions in the temperature range 120-150 degrees C and different reaction times was investigated. The products analyzed by electron microscopy, X-ray diffraction, FT-IR and elemental analysis contains--depending of the ami...

A comparative study among different pretreatment methods used for the fractionation of the birch outer bark components, including steam explosion, hydrothermal and organosolv treatments based on the use of ethanol/water media, is reported. The residual solid fractions have been characterized by ATR-FTIR, (13)C-solid-state NMR and morphological alterations after pretreatment were detected by sca...
