Core-shell structured Nd(3+)-sensitized NaYF4:Yb/Nd/Er@NaYF4:Nd@mSiO2 nanoparticles (NPs) were designed and synthesized. The NaYF4:Yb/Nd/Er@NaYF4:Nd core imparts the nanomaterials with luminescence properties for upconversion optical imaging under 808 nm laser irradiation, whereas the mesoporous SiO2 shell allows the…
A green, simple, and efficient technology for direct production of cellulose mixed esters with acetyl and long chain acyl substituents.
A novel ferrocene-based nanoporous organic polymer has been prepared by coupling 1,1′-ferrocene-dicarboxaldehyde with melamine.
In this study, well-intergrown NiAl–CO <sub>3</sub> LDH films with excellent anti-corrosive capacity, considerable long-term corrosion durability as well as strong mechanical stability are prepared from CO <sub>2</sub> -saturated precursor solution in one step.
A series of gallium and indium complexes containing a bis(imino)phenolate ligand framework were synthesized and completely characterized with different spectroscopic techniques. The molecular structures of a few complexes were determined using single crystal X-ray diffraction studies. These compounds were found to be…
A facile method for detection of Hg <sup>2+</sup> in living cells based on DNA modified graphene quantum dots.
The phenomenon of ‘self-purification’ is a real mechanism operative in nanocrystals and this should be taken into account while doping semiconductor nanocrystals with external impurities for practical applications.
Nitrogen-doped graphene oxide dots exhibit excitation-wavelength independent photoluminescence at 530 nm and 50% quantum yield. The dots show excellent white light emission by combining green emissions with violet light used for excitation.
Growing interest in developing devices that can be implantable or wearable requires the identification of suitable materials for the components of these devices. Electrochemical supercapacitors are not the exception in this trend, and identifying electrode materials that can be not only suitable for the capacitive dev…
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 <sub>3</sub> PO <sub>4</sub> -PySH is prepared through introducing redox-mediated PySH into PVA-H <sub>3</sub> PO <sub>4</sub> 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.
