Difference atomic pair distribution function methods have been applied to detect and characterize nanoparticles suspended in a solvent at very dilute concentrations. We specifically consider nanoparticles of a pharmaceutical compound in aqueous solution using X-ray PDF methods, a challenging case due to the low atomic…
A nanotube-shaped PPy–Pd composite, as an antibacterial agent, was prepared using a unique combination of green synthesis and a microemulsion method.
The results on the elemental and mineralogical compositions of clays from Central Uganda differed from those from the volcanic sediments of the Mt. Elgon in Eastern Uganda. Utilisation of the two types of clays should be strict after understanding their structural differences. Whereas elemental, mineralogical, DTA, IR…
We present a comprehensive evaluation of the variabilities and uncertainties present in determining the kinetics of water transport in ultraviscous aerosol droplets, alongside new measurements of the water transport timescale in sucrose aerosol. Measurements are performed on individual droplets captured using aerosol…
By combining the reflection‐absorption infrared spectral studies with the peak fitting analysis we determined the type of the silicon oxides present in polydimethylsiloxane layers obtained on germanium and aluminium substrates in corona discharges. We have also evidenced that the dependence of silicon oxides density o…
The process of extraction of cellulose nanofibrils by steam explosion followed by electrospinning with biodegradable polymers to yield PCL/PVA nanoencapsulated cellulosic reinforcing fillers for tissue engineering applications.
In this paper, electro-catalytic reduction of oxygen in Sr-doped lanthanum nickelates, La 2-x Sr x NiO 4+δ (0 ≤ x ≤ 0.4) Ruddlesden-Popper (R-P) phase, has been investigated. The oxygen reduction reaction (ORR) kinetics is evaluated via electrochemical impedance spectroscopy (EIS) with the symmetric cell configuration…
Vibrational spectroscopies as analytical tools to investigate the interaction of sago starch-capped silver nanoparticles with collagen scaffolds for biomedical applications.
A novel gel polymer PVA-H 3 PO 4 -PySH is prepared through introducing redox-mediated PySH into PVA-H 3 PO 4 host, and a solid state supercapacitor is fabricated using the gel polymer as electrolyte and separator, activated carbons as electrodes.
A complete thermodynamic and kinetic solution study on lanthanide(III) complexes with monoacetamide (DOTAMA, L1) and monopropionamide (DOTAMAP, L2) derivatives of DOTA (DOTA = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid) was undertaken with the aim to elucidate their stability and inertness in aqueous med…
Is it possible to blend two immiscible polymer networks starting from their cured state? A simple thermomechanical approach permits blending two dynamically crosslinked polymer networks, to give blends with superior mechanical properties.
Charged nanofibers were prepared by electrospinning (ESP) poly(ε-caprolactone) with a copolymer bearing carboxylic acid functions. The presence of these functions allowed exposing some negative charges on the fiber surface, by dipping the fibers in a phosphate buffer. A layer of chitosan, a polycation in acidic medium…
YVO 4 :Eu/Fe 3 O 4 can be used for optical imaging and hyperthermia in cancer cells.
A novel homogeneous biosensor based on the fluorescence polarization enhancement effect of the SiO 2 NP–DNA/Ag nanocluster sandwich structure has been developed for sensitive and selective detection of hepatitis B virus DNA.
CaGd 2 ZnO 5 :Tb 3+ nanophosphors showed the broadened excitation region as compared to Y 2 O 3 :Tb 3+ and Gd 2 O 3 :Tb 3+ phosphors, which covered almost the entire UV-B and UV-A regions.
BaTiO 3 /MWNT/PBO ternary composites with excellent microwave absorption properties, mechanical properties and thermostabilities.
Platinum(iv) complexes take advantage of the exclusive conditions that occur within the tumor to carry out their cytotoxic activity. On the other hand, silk fibroin has natural properties which make it very interesting as a biomaterial: high biocompatibility, biodegradability, low immunogenicity, high cellular penetra…
We explore the effects of the particle size and the surface charge of polyelectrolyte-coated titania nanoparticles on their toxicity towards green microalgae and yeast cells in UV/vis light.
Applying the Förster formalism we studied the potential of urethane-like linkage at the surface of CDs to form donor–acceptor FRET pair in CD–Rhodamine conjugates.
Herein we developed a novel strategy for preparing biodegradable PLA based materials with improved crystallinity, mechanical properties and rheological behaviour by introducing a long-chain branched block copolymer of PLA and PCL.
