Core–shell structured Gd <sub>2</sub> O <sub>3</sub> :Ln@ <italic>m</italic> SiO <sub>2</sub> hollow microspheres with an interesting double-shell and mesoporous structure have been fabricated. The luminescent composite shows obvious drug storage and release properties.
at 30 MHz can be reached, which highlighted the fact that molecular motion of the Gd chelate was effectively restricted and water access to the inner core of these nanogels was not limited.
Using solar energy for the decontamination of wastewater is a promising solution to the water-energy nexus. Current advanced oxidation processes have an unsatisfactory efficiency in the treatment of dye wastewater due to the non-selectivity of hydroxyl radicals. More efficient photochemical approaches for dye degradat…
Poly N-isopropyl acrylamide (PNI) radically polymerized in aqueous solution in the presence of graphene oxide (GO) can significantly change the properties of the resulting solution from a regular polymer solution to a soft solid with a GO content of only 0.176 wt% (3 wt% with respect to PNI). However, these properties…
A single-layer antireflective (SLAR) coating with extremely high photovoltaic transmittance ( <italic>T</italic> <sub>PV</sub> ) at 400–1100 nm was designed with the aid of thin film design software (TFCalc™).
Cassava and tree cassava starch films plasticized with glycerol were produced by casting method. Different glycerol contents (30, 35, 40 and 45 wt. % on starch dry basis) were used and the resulting films were fully characterized. Their water barrier and mechanical properties were compared. While increasing glycerol c…
A very rare area negative thermal expansion phenomenon is observed in a newly discovered alkali beryllium borate LiBeBO3, which is characterized by [BeBO3]∞ double layers intraconnected by edge-sharing BeO4 tetrahedra. This unusual thermal behavior is attributed to the combined vibrational effects of the abnormal Be-O…
Combining Fe(ii) with the carboxylate-functionalized 2,6-bis(pyrazol-1-yl)pyridine (bppCOOH) ligand results in the spin-crossover compound [Fe(bppCOOH)2](ClO4)2 which shows an abrupt spin transition with a T1/2 of ca. 380 K and a TLIESST of 60 K due to the presence of a hydrogen-bonded linear network of complexes.
Coral-like mesoporous NiO nanobars, which possess favourable pseudocapacitive properties, have been fabricated by a facile and template-free coprecipitation method followed with a simple calcination procedure.
Diffusion of small to medium sized molecules in polymeric medical device materials underlies a broad range of public health concerns related to unintended leaching from or uptake into implantable medical devices. However, obtaining accurate diffusion coefficients for such systems at physiological temperature represent…
The effect of pre-strain before hydrogen charging on the resistance to hydrogen embrittlement (HE) in the 316L austenitic stainless steel was investigated through the slow strain rate tensile test (SSRT), transmission electron microscopy, and thermal desorption analysis (TDA). The pre-strain suppressed mechanical twin…
GdNbO <sub>4</sub> :Ln <sup>3+</sup> (Ln = Dy, Eu) single crystal phosphors are very important for potential applications in optoelectronics and solid-state lighting for general illumination.
Addition of wood flour improve the mechanical properties of thermoplastics, on the other hand it increases the burning speed of the materials. To modify the flammability of wood-plastic composites(WPC), various fire retardants, such as ammonium polysphosphate (APP), melamine polyphosphate (MPP) and aluminum hydroxide…
The modifications of the stoichiometry, morphology and surface structure of cerium oxide ultrathin films induced by thermal treatments under vacuum and oxygen partial pressure were studied using in situ X-ray photoemission spectroscopy, scanning tunnelling microscopy and low energy electron diffraction. The effect of…
A silver-tolerant (3.5 mM silver nitrate) marine bacterial isolate ( Bacillus sp.) was used for biosynthesis of Ag-nanoparticles. UV-Vis spectra showed an absorption peak between 410 and 440 nm. Transmittance electron microscopic (TEM) analysis indicated the presence of 2 to 7 nm Ag-nanoparticles. O 2 -plasma pretreat…
A B S T R A C T Nanotechnology is an emerging field in the area of interdisciplinary research, especially in biotechnology. In this study the copper nanoparticles are synthesized by using a plant leaf extract of Vitis vinifera. The reduction of copper sulphate to copper nanoparticles was confirmed by UV-visible spectr…
Due to the conflicting reports on the antioxidant activity of cerium oxide nanoparticles, much work has been done to explore the factors influencing the antioxidant activity of nano-CeO <sub>2</sub> .
nanocrystals can be used as MRI and fluorescence imaging dualmodal contrast agents. The developed technique is expected to be a general, facile and environmentally friendly strategy towards synthesizing rare earth doped nanoparticles for biomedical applications.
The unexpectedly high quadratic hyperpolarizability values of simple Ru and Pt alkynyl complexes have been measured by the EFISH technique, and this prompted us to investigate their potential as molecular building blocks for composite films with second harmonic generation properties.
We report the generation of a novel self-assembled platinum (Pt) prodrug from a short peptide derivative, which acted as a substrate for the phosphatase-catalyzed dephosphorylation reaction, and a Pt(iv) complex, which could undergo supramolecular self-assembly in the presence of alkaline phosphatase, and perform cont…
