Alkali-activated materials (AAMs) and “geopolymers” are inorganic polymeric obtained by mixing of solid aluminosilicate precursors with an alkaline solution (generally, KOH or NaOH Na2SiO3 mixed in various ratios). This class has emerged as a greener alternative to traditional concrete, for large-scale well niche applications such conservation restoration built heritage. In this work we apply R...

– X-ray reflectometry and GISAXS (grazing angle small angle scattering) are combined to investigate the morphology and structural parameters of a surfactant templated 2D hexagonal thin-film silica mesophase. It is shown that X-ray reflectivity measurements contain invaluable information about the radius of the cylindrical rods and the distance between their cores. The reflectivity data are anal...

impurities of drug substances may produce some side effects in patient. diclofenac na is a member of non-steroidal anti inflammatory drugs (nsaids) family, which is routinely used by patients for the treatment of rheumatoid arthritis and various pains. to develop a method for the determination of synthetic precursors which could be remained as impurities in raw drug materials, na diclofenac pow...

Highly uniform 3-D ordered macroporous spheres in regular arrays were produced by a double templating process. The first template of larger silica balls produced the polymer skeleton for guiding the shape and size of the self-assembled superstructure of smaller polymeric balls, which are introduced subsequently into the internal space of the skeleton. The second templating with inorganic precur...

Artificial photosynthesis, modeled on natural light-driven oxidation of water in Photosystem II, holds promise as a sustainable source of reducing equivalents for producing fuels. Few robust wateroxidation catalysts capable of mediating this difficult four-electron, four-proton reaction have yet been described. We report a new method for generating an amorphous electrodeposited material, princi...

Size-controllablemonodisperse CdSe nanocrystals with different organic cappingwere prepared based on the hot-injectionmethod. The effective separation of nucleation and growthwas achieved by rapidlymixing two highly reactive precursors. As a contrast, we preparedCdSe/CdS nanocrystals (NCs) successfully based on the selective ion layer adsorption and reaction (SILAR) technique. This inorganic ca...

Microreactors fabricated with optically transparent inorganic polymers from two types of ceramic precursors using a UV-micro-imprinting process demonstrated reliable solvent resistance, biocompatible and capability for performing photo catalytic and organic synthetic reactions, which were compared with batch systems and glass based microreactors. It is for the first time that the polymer-based ...

Atomic-scale integration of polyether molecules and copper(II) chloride layers in a two-dimensional perovskite affords, to the best of our knowledge, the first example of extended Li(+) cycling in a metal chloride electrode. The hybrid can cycle over 200 times as a cathode in a lithium battery with an open-circuit voltage of 3.2 V. In contrast, CuCl2 alone or the precursors to the hybrid cannot...

The EO20PO70EO20 (molecular weight 5800) amphiphile as a template is to form dispersed micelle structures. Silver nanoparticles, as inorganic precursors synthesized by a laser ablation method in pure water, are able to produce the highly ordered vesicles detected by TEM micrography. The thickness of the outer layer of a micelle, formed by the silver nanoparticles interacting preferentially with...

Organic compounds and liquid water are major aerosol constituents in the southeast United States (SE US). Water associated with inorganic constituents (inorganic water) can contribute to the partitioning medium for organic aerosol when relative humidities or organic matter to organic carbon (OM /OC) ratios are high such that separation relative humidities (SRH) are below the ambient relative hu...
