Castor oil was efficiently used as a raw material for the synthesis of polyesters and poly(ester-amide)s. Aliphatic diols containing monoester, diester, ester-amide, monoamide and diamide linkages were synthesized from methyl 10-undecenoate through transesterification, amidation and thiol–ene reactions. These diols we…
The synthesis of silver nanoparticles of varying size has been achieved using different molar concentrations of NaOH while the effect of changing the temperature has been studied. A g NO 3 , gelatine, glucose and NaOH are used as a silver precursor, stabilizer, reducing agent and accelerator respectively. The synthesi…
The mechanical properties of particle laden interfaces are investigated by studying capillary wave propagation along the interface. Interfaces are coated with monodisperse silica hydrophobic particles with diameters ranging from 35 μm to 159 μm. The surfaces are prepared with a particle density just above that require…
Hollow Ru nanoparticles with ~14 nm diameter and ~2 nm shell thickness are reported for the first time, by removal of Ni from the delicately designed Ni@Ru core@shell NPs. Such hollow Ru NPs exhibit enhanced catalytic activity in the dehydrogenation of ammonia borane with respect to solid ones.
This study focused on exploring the feasibility of green composites made from biodegradable and renewable materials as potential alternatives to petroleum polymer composites and understanding the reinforcing mechanisms in composites containing kenaf fibers (KF). KF-reinforced poly(lactide) acid (PLA) composites were m…
A novel method is introduced to fabricate an electroactive epoxy (EE) coating with structured hydrophobic surfaces using an environmentally friendly process for anticorrosion application. First of all, the electroactive amine-capped aniline trimer (ACAT) was used as a curing agent to cure the epoxy resin and additiona…
First-principles calculations of the crystal structure and the elastic properties of tetragonal WN2 have been performed with the plane-wave pseudopotential density functional theory method. The calculated structural parameters and elastic constants at zero pressure and temperature are in excellent agreement with the a…
The presence of boron in the structure of diamond is rare in nature, and even when present, reported values are ≤0.5 ppm. This study used various spectroscopic methods and time-of-fight (ToF-) SIMS to characterize and analyze for boron in natural type IIb blue diamonds, including the well-known Hope and the Blue Heart…
Non-layered chalcopyrite-type CuInSe(2) nanoplatelets, with thickness down to 2 nm, have been synthesized for the first time. The ultrathin nanoplatelets are of benefit for low-cost and high performance flexible photodetectors.
Monoclinic Gd(1-x)Eu(x)BO(3) nanopowders were successfully synthesized using a modified Pechini method. The crystal structure of the prepared materials was revised and confirmed using several techniques such as: IR, XRD, TEM, Raman spectroscopy and EDX analysis. The obtained material was comprised of particles, consis…
In order to prepare new promising optical nanoprobes, long afterglow nanospheres with a narrow size distribution were successfully synthesized using mesoporous silica nanospheres (MSNs) both as morphology-controlling templates and the silicon source of long afterglow silicate. In our experiments, metal ions (Sr2+, Mg2…
Silk electrogelation involves the transition of an aqueous silk fibroin solution to a gel state (E-gel) in the presence of an electric current. The process is based on local pH changes as a result of water electrolysis - generating H(+) and OH(-) ions at the (+) and (-) electrodes, respectively. Silk fibroin has a pI=…
This review describes the attractiveness of catalytic self-assembled monolayers (SAMs) on gold nanoparticles as catalytic systems. The hybrid inorganic–organic catalytic systems combine the advantages of homogeneous and heterogeneous catalysis (higher activity and catalyst recycling, respectively). The high fidelity p…
Monocrystalline cellulose nanocrystals (nanowhiskers), prepared by acid hydrolysis of cotton wool followed by Soxhlet extraction in ethanol to remove adsorbed impurities, were modified with poly(ε-caprolactone) using a “grafting from” approach, with citric acid, a benign naturally available organic acid, as the cataly…
An unusual dinuclear Yb(2) complex isolated using a mixed ligand strategy leads to field-induced SMM behaviour. Low magnetic axiality and a large tunnelling gap lead to significant quantum tunnelling of the magnetisation, which was reduced under an applied static optimum field of 1600 Oe.
A highly efficient strategy for one-pot synthesis of programmable, crystalline-amorphous stereomultiblock PLA from rac-lactide.
Adipose tissue pathologies and defects have always represented a reconstructive challenge for plastic surgeons. In more recent years, several allogenic and alloplastic materials have been developed and used as fillers for soft tissue defects. However, their clinical use has been limited by further documented complicat…
We demonstrate a route toward the preparation of healthier fruit juice infused chocolate candy. Up to 50 wt% of the fat content in chocolate, that is cocoa butter and milk fats, is replaced with fruit juice in the form of emulsion droplets using a quiescent Pickering emulsion fabrication strategy. Fumed silica particl…
The biogeochemistry of phyllosilicate-Fe redox cycling was studied in a Phalaris arundinacea (reed canary grass) dominated redoximorphic soil from Shovelers Sink, a small glacial depression near Madison, WI. The clay size fraction of Shovelers Sink soil accounts for 16% of the dry weight of the soil, yet contributes 7…
A kind of molecular metal chalcogenide, (N(2)H(4))(3)(N(2)H(5))(4)Sn(2)Se(6) complex, was synthesized in the hydrazine solution and employed as the precursors for SnSe(2) deposition on TiO(2) nanocrystalline porous films. A power conversion efficiency of 0.12% under AM 1.5, 1 sun was obtained for the SnSe(2) sensitize…
