The effect that monodisperse amorphous spherical silica particles of different sizes have on the viability endothelial cells (EAHY926 cell line) is investigated. results indicate exposure to nanoparticles causes cytotoxic damage (as indicated by lactate dehydrogenase (LDH) release) and a decrease in survival determined tetrazolium reduction, MTT, assay) EAHY926 line dose-related manner. Concentrations leading 50% reduction (TC(50)) for smallest tested (14-, 15-, 16-nm diameter) ranging from...
A breakthrough result: The microporous metal–organic framework MIL-47 is an excellent adsorbent for the separation of C8 alkylaromatic compounds, such as ethylbenzene, meta-xylene, and para-xylene. potential MIL-47, with its high uptake capacity hydrophobic nature, real separations compounds was demonstrated by chromatographic experiments (see picture).

Photocatalytic reduction of molecular oxygen is a promising route toward sustainable production hydrogen peroxide (H2O2). This challenging process requires photoactive semiconductors enabling solar energy driven generation and separation electrons holes with high charge transfer kinetics. Covalent organic frameworks (COFs) are an emerging class semiconductors, tunable at level for carrier transfer. Herein, we report two newly designed two-dimensional COFs based on (diarylamino)benzene linker...
The metal−organic framework MIL-53(Al) was tested for selective adsorption and separation of xylenes ethylbenzene, ethyltoluenes, cymenes using batch, pulse chromatographic, breakthrough experiments. In all conditions tested, MIL-53 has the largest affinity ortho-isomer among each group alkylaromatic compounds. Separations ortho-compounds from other isomers can be realized a column packed with crystallites. As evidenced by Rietveld refinements, specific interactions pore walls determine...
Porous polymer supported continuous ZIF-8 membranes were prepared via an interfacial synthesis method. Membranes with only one cycle showed excellent performance in the nanofiltration range.
Metal–organic frameworks (MOFs) are an emerging class of materials for potential use in separation. ZIF-71 has super-hydrophobic pore channels and a very flexible architecture, which make candidate recovering bio-alcohols from fermentation broths. In the present study, mixed matrix membranes (MMMs) based on PDMS were prepared separation alcohols (methanol, ethanol, isopropanol (IPA) or sec-butanol) aqueous solutions. Experimental results reveal that pervaporation performance membrane was...
Extensive research has been carried on the molecular adsorption in high surface area materials such as carbonaceous and MOFs well atomic bonded hydrogen metals alloys. Clathrates stand among ones to be recently suggested for storage. Although, simulations predict lower capacity than expected by DOE norms, additional benefits of clathrates low production operational cost, fully reversible reaction, environmentally benign nature, risk flammability make them one most promising explored next...
Abstract Vacancy engineering has been proved repeatedly as an adoptable strategy to boost electrocatalysis, while its poor selectivity restricts the usage in nitrogen reduction reaction (NRR) overwhelming competition from hydrogen evolution (HER). Revealed by density functional theory calculations, selenium vacancy ReSe 2 crystal can enhance electroactivity for both NRR and HER shifting d‐band −4.42 −4.19 eV. To restrict HER, we report a novel method burying vacancy‐rich @carbonized...
Agrivoltaic (AV) production systems combine renewable energy- and crop production. Two arable agrivoltaic pilot sites with vertical, horizontal, tracking setups were constructed in Belgium between 2019 2022. Field trials for sugar beet wheat conducted two consecutive seasons. Beet grown vertical or tracked AV achieved a reduced average yield of 11–19% the cultivation area, land-loss 11%, an electricity 376–560 MWh/ha across Although leaf pigments AV-grown plants reduced, suggesting...
29Si liquid NMR and in situ infrared spectroscopy was used to investigate the polycondensation process of tetraethyl orthosilicate (TEOS) a concentrated aqueous solution tetrapropylammonium hydroxide (TPAOH) at low temperatures. The composition characterized by molar hydrolysis ratio (H2O/TEOS) 6 TPAOH/TEOS 0.37. spectra samples recorded different reaction times temperatures were assigned limited number specific silicate polyanions containing three five rings. structure directing action...
We have developed a united atom force field able to accurately describe the adsorption properties of linear alkanes in sodium form FAU-type zeolites. This successfully reproduces experimental n-alkanes over wide range cation densities, temperatures, and pressures. The positions dehydrated zeolites known from crystallography, it predicts how cations redistribute when adsorb. sodalite cages are significantly more sensitive n-alkane loading than those supercages. provide simple expression that...
In recent years, the production of hydrocarbon cuts from various sources via Fischer-Tropsch process has lived a renewed interest. Paraffinic produced reaction can be upgraded either to liquid fuels (middle distillates) or lubricant base oil high quality. The first kind upgrading involves use hydrocracking catalyst whereas for second selective hydroisomerization catalysts selected. Both are bifunctional and contain an hydrogenation/dehydrogenation function acidic function; however, it is...
Processing metal–organic frameworks with spatial and temporal control over crystal formation will increase the applicability of these highly porous materials. By exploiting solvent effects, stable synthesis solutions can be obtained, which used in combination soft lithographic techniques to deposit oriented crystals patterns by situ crystallization (see figure). Detailed facts importance specialist readers are published as ”Supporting Information”. Such documents peer-reviewed, but not...
