Silver nanoparticles (AgNP) confined within porous starch have been prepared in a simple, green and efficient manner, utilising the nanoporous structure of predominantly mesoporous starch (MS) to act as nanoparticle stabiliser, support and reducing surface. MS/AgNP materials present high surface areas (S(BET) > 150 m(2) g(-1)) and mesopore volumes (V(meso) > 0.45 cm(3) g(-1)). The interaction o...

A novel hierarchical nanotemplated carbon monolithic rod (NTCM) was prepared using a novel facile nanotemplating approach. The NTCM was obtained using C60-fullerene modified silica gels as hard templates, which were embedded in a phenolic resin containing a metal catalyst for localized graphitization, followed by bulk carbonization, and template and catalyst removal. TEM, SEM, and BET measureme...

This study considers desorption kinetics for 12 field-aged polycyclic aromatic hydrocarbons (PAHs) desorbing from size- and density-fractionated sediments collected from two locations in the New York/New Jersey Harbor Estuary. Desorption kinetics for PAHs with a log octanol-water partition coefficient greater than 6 were well-described by a one-domain diffusion model that assumes that PAHs are ...

Surfactant-templating is one of the most versatile and useful techniques to implement mesoporous systems into solid materials. Various strategies based on various interactions between surfactants and solid precursors have been explored to produce new structures. Zeolites are invaluable as size- and shape-selective solid acid catalysts. Nevertheless, their micropores impose limitations on the ma...

Synthetic mesoporous alumina and silica minerals with uniform pore geometries, and their nonporous analogues, were used to test the role of mineral mesopores (2-50 nm diameter) in protecting organic matter from enzymatic degradation in soils and sediments. Dihydroxyphenylalanine (L-DOPA), a model humic compound, was irreversibly sorbed to both mineral types. The surface area-normalized adsorpti...

The impact of zeolite hierarchization is often highlighted in terms increased mesopore volume or specific surface area and preservation micropore volume. Yet, although these targets may be achieved, the accessibility to certain micropores might negatively affected during hierarchization. A set hierarchical MCM-22 based materials prepared on desilication treatments MCM-22, layered precursor MCM-...

The Jurassic Dongyuemiao Member is the most promising target for lacustrine shale gas exploration in Sichuan Basin. By integrating SEM, NMR, LTNA, and MICP experiments, other basic measurements, nanoscale pore category structure corresponding controlling factors of Eastern Basin are studied. results denote that organic pores comprise primary within plant debris secondary bitumen. Inorganic comp...

In the spatial confinement of cylindrical mesopores with diameters a few nanometers, water molecules experience restrictions in hydrogen bonding. This leads to different behavior regarding molecular orientational freedom (‘structure water') compared bulk liquid state. addition pore size, is also strongly affected by strength wall-to-water interactions, that is, wall polarity. this work, studied...

The synthesis of modified bimodal mesoporous materials (BMMs) with a small pore size of around 2.9 nm and a large pore size of about 20 nm has been performed via post-grafting methods. To study the application of functionalized BMMs in drug delivery, loading and releasing profiles using aspirin as model drug were carried out. XRD, SEM, TEM, N2 adsorption, FT-IR, 29Si-NMR, TG and UV-Vis spectros...
