PW-MOF as an efficient, recyclable and stable catalyst for the selective oxidation of alkenes with hydrogen peroxide.
The feasibility of preparing activated carbon from carbohydrates (glucose, sucrose and starch) with H 3 PO 4 activation was evaluated by comparing its physicochemical properties and Ni( ii ) adsorption ability with a reference Phragmites australis -based activated carbon.
The article presented the aqueous-phase reforming of ethylene glycol over Ni/Zn/Al hydrotalcite. The results showed that the H 2 yield and selectivity were 73% and 96%, respectively. The conversion of ethylene glycol was >99%.
Core–shell-structured nanocapsules consisting of a nickel ferrite (NiFe 2 O 4 ) nanoparticle core encapsulated in an onion-like carbon (C) shell are prepared by a modified arc-discharge method followed by an air-annealing process.
1-Dimensional homogenous nanocolumnar structures prepared without any template method for efficient perovskite solar cell fabrication.
Citric acid (CA) was used in a thermally induced phase separation (TIPS) process to improve the surface hydrophilicity and cell affinity of PLLA nano-fibrous scaffolds. The evolution of architecture, structure and physicochemical properties of the scaffold after modification has been investigated. Cell viability, adhe…
In this work, we report improved performance by controlling morphology using different fullerene derivatives in PBDT-TBT-alkoBT based organic solar cells.
Freeze-thaw processing of bovine serum albumin (BSA) aqueous solutions, which contain also the additives of denaturants (urea in this case) and thiol-bearing reductants [cysteine (Cys) in this case] leads to the formation of wide-pore cryogels. The properties and porous morphology of these spongy gel matrices were dem…
, forming a crosslinked hydrogel scaffold. It was shown in this study that the precursor solution remained as a liquid on the order of hours at 20 °C, yet gelation could be induced within minutes by heating to 37 °C. Furthermore, it was shown that HRP release could be controlled by various material and processing para…
There is an increasing number of compounds developed to target one or more pathways involved in vasodilation. Some studies conducted with azaindole and indazole derivatives showed cardiovascular activity associated with these compounds. Fast and easy structural modification of these organic molecules can be achieved u…
Although titanium (Ti) implants are already being broadly used, further improvement is still mandatory for improving its clinical performance. To this end, small interfering RNA (siRNA) biofunctionalization may present a novel strategy. In this study, siRNA biofunctionalization was realized on a titania nanotube array…
We fabricated a new sea urchin-like zirconium( iv ) oxide which exhibits efficient phosphate sequestration with remarkable selectivity, a large capacity and recyclability .
Brick clay from a locality Radobica, Central Slovakia, which was exploited for brick manufacturing in the past, was investigated for its possible reuse in the brick industry. The crystalline phases of the green sample were 48% of quartz, 37% of illite, 13%, of Na-feldspar and 2% of calcite. The measurements of Young's…
Value addition of seaweed polysaccharides by their functional modification with various substrates leading to new effects.
The helical assembly is a fundamental organization principle of biomacromolecules. To determine the structures of helical filaments or tubes has been helped by the fact that many different views of the helical unit are present to reconstruct a three-dimensional image from a single helix. In this review, I present the…
CuInS 2 (CIS) thin films have proven to be promising candidates for photovoltaic technology but still the cost and safety of their fabrication processes remain challenging topics for research and development.
In this study, we constructed a layered graphene oxide (GO) nanocomplex with pH-responsive charge-reversible chitosan-aconitic anhydride (CS-Aco), biocompatible polyethylene glycol (PEG) and low molecular weight polyethylenimine (PEI). This was employed as a novel delivery system for intracellular pH-triggered DOX and…
Silver loaded TiO 2 samples were prepared by photodeposition of different amounts of Ag + ions over commercial titanium dioxide (Evonik TiO 2 P25) in aqueous media without the presence of sacrificial agents.
In this study, AgInZnS-reduced graphene (AIZS-rGO) nanocomposites with tunable band gap absorption and large specific surface area were synthesized by a simple hydrothermal route, which showed highly efficient photocatalytic hydrogen evolution under visible-light irradiation. The relationships between their crystal st…
The incorporation of active sites into metal-organic frameworks (MOFs) or porous coordination polymers (PCPs) is an attractive way to functionalise these materials. However, the methodology to organise substitution-inert metal-based secondary building units (SBUs) with active sites into MOFs or PCPs via coordination d…
