The selective hydrogenation of fluorinated arenes with polar functionalities to valuable cyclohexanes is achieved using supercritical CO 2 as solvent in combination Rh NPs immobilized on molecularly modified silica catalysts.

The valorisation of technical lignins by conversion is herein demonstrated using an acidic deep eutectic solvent in the absence or presence a co-catalyst (H 2 SO 4 H O ).

Lipase-displaying whole cells appear to be efficient biocatalysts because of their low preparation costs and simple recycling procedure. The combined utilization of Candida antarctica lipase B (CALB) and Rhizomucor miehei lipase (RML), separately displayed on Pichia pastoris whole cells, to produce biodiesel in co-solvent media was investigated. A response surface methodology incorporating a D-...

Confinement of a catalyst can have significant impact on catalytic performance and lead to otherwise difficult achieve properties. Herein, we report the design synthesis novel caged system Co?G@Fe8(Zn?L ? 1)6, which is soluble in both polar apolar solvents without necessity any post-functionalization. This rare example metal-coordination cage able bind catalytically active porphyrins that spann...

In the title cluster complex hexane solvate, [Ru6(C30H32P2)(CO)22]·C6H14, two Ru3(CO)11 fragments are linked by a Ph2P(CH2)6PPh2 bridge with the P atoms equatorially disposed with respect to the Ru3 triangle in each case; the hexane solvent mol-ecule is statistically disordered. The Ru⋯Ru distances span a relatively narrow range, i.e. 2.8378 (4) to 2.8644 (4) Å. The hexyl chain within the bridg...

Biodegradable polymers have become the materials of choice for a variety of biomedical applications. In particular, poly(DL-lactide-co-glycolide) nanoparticles have been studied as a material for drug delivery with the controlled release. In this paper we are describing a simple method for obtaining the system for targeted and controlled delivery of folic acid in the body. Folic acid was encaps...

In a series of publications we have described the kinetics of free-radical formation from molybdenum carbonyl in association with organic halides in a number of electron-donating solvents. Radical formation involves the displacement of carbon monoxide from the carbonyl by the solvent or vinyl monomer in a rate-determining process giving rise to complexes of the type Mo(CO)5L (where L represents...

A homologous series of propylene carbonate (PC) analog solvents with increasing length of linear alkyl substitutes were synthesized and used as co-solvents with PC for graphite-based lithium-ion half cells. A graphite anode reaches a capacity of around 310 mAh/g in PC and its analog co-solvents, with 99.95 percent Coulombic efficiency, similar to the values obtained with ethylene carbonate-base...

Guide regeneration techniques have been recently used to heal soft and hard tissue defects. In this approach, scaffolding plays an important role. Hydroxypatite (HA) resembles the natural bone mineral and has shown good bone bonding properties. In this work, porous polyurethanes have been prepared by a thermally induced phase separation technique. Freeze drying of the separated polymer/solvent ...

In the title polymer, {[Co(C(14)H(10)N(2)O(4))(H(2)O)]·3.5H(2)O}(n), the Co(2+) ion is coordinated by three carboxyl-ate O atoms from two 5-[(pyridin-2-ylmeth-yl)amino]-isophthalate anions, two N atoms from a (pyridin-2-ylmeth-yl)amino group and an O atom from a water mol-ecule, furnishing a distorted CoO(4)N(2) octa-hedral geometry. Each anion acts as a μ(3)-bridge, linking cobalt ions into a ...
