Sensitive detection and efficient removal of an increasing number of persistent and emerging environmental pollutants are major challenges in our industrialized world. Now these challenges can be better answered by utilizing the advantages of nanotechnology in addition to traditional methods. Due to unique features of…
One of the most widely studied subjects in nanoscience technology is related to the creation of supramolecular architectures with well-defined structures and functionalities. These supramolecular structures are generated as a result of self-assemblage of amphiphilic block polymers. Self-assembly of block polymers via…
In this work, we present a novel concept of structural design for the synthesis of a new type of core/shell structure comprising γ-MnO2 cores inside hollow α-MnO2 shells. The approach involves two main steps. First, MnCO3 microellipsoids were mixed directly with KMnO4 solution, which lead to a manganese oxide shell on…
Flexible single-walled carbon nanotubes/polyaniline (SWNT/PANi) composite films with enhanced thermoelectric properties were prepared via a simple method. Furthermore, these paper-like composite films show good flexibility, which makes them possible to be widely applied in various flexible energy converter devices.
We report luminescence properties of Ce3+ and Mn2+ co-activated Ca3Sc2Si3O12 (CSS) silicate garnets. It is observed that Mn2+ may not only occupy Ca2+ sites to generate a yellow emission (Mn2+(I)) at 574 nm but also Sc3+ sites to generate a red emission (Mn2+(II)) at 680 nm. Considerable Mn2+ substitution for Sc3+ can…
The long-term isothermal oxidation behavior of bulk Ti 2 AlC in air and 100% water vapor has been investigated in the 1000–1300°C temperature range. The kinetics, for oxidation up to 120 hours, follows a cubic rate law in both environments – air and water vapor. The kinetics was found to be slightly faster for hydroth…
In this article, we report the fabrication of monodisperse hollow mesoporous silica (HMS) nanocages with uniform size possessing a hollow cubic core and mesoporous shell with penetrating pore channels based on a template-coating-etching process. It is worthwhile noting the obtained HMS nanocages with cubic void space…
Organic photochromic materials based on diarylethenes and their derivatives have been intensively investigated from fundamental research to technological applications. This review briefly presents the latest advances in photochromic polymers containing diarylethenes and their derivatives. Polymer matrices doped with d…
These studies elucidate the origin of molecular and macroscopic processes of oxetane-substituted chitosan-polyurethane (OXE-CHI-PUR) crosslinked networks that occur inside a mechanically generated scratch during UV-initiated self-repair. The role of each network component, OXE, CHI, PUR, and dibutyltin dilaurate (DBTD…
As an alternative choice to CdSe nanocrystals synthesized in organic phase, CdTe nanocrystals synthesized in aqueous solution, have attracted increasing research interests in recent years. This feature article summarizes the aqueous solution-based syntheses, some optoelectronic applications, and bioapplications of CdT…
A general and facile method was used for preparation of water-soluble silica coated LaVO4:Eu3+ core-shell nanoparticles. In the present study, we have discussed and compared the cytotoxicity characteristics of the synthesized LaVO4:Eu3+ and silica coated LaVO4:Eu3+ core-shell nanoparticles. X-ray diffraction (XRD), fi…
Aqueous lithium ion batteries (LIBs) can fundamentally resolve the safety problem arising from the use of highly toxic and flammable organic solvents, and effectively reduce the manufacturing cost. But many reported aqueous lithium ion battery systems have shown poor stability with capacity retention decreasing rapidl…
An increase in nanomaterial applications will likely lead to an increased probability of environmental exposures, raising concerns regarding the safety of these materials. Recent studies have indicated that manufactured nanomaterials, such as metal oxides, have the potential to be harmful to aquatic and terrestrial or…
In this work, we have synthesized eccentric Au@TiO(2) core-shell nanostructures and demonstrated their multiple reuse in the catalytic reduction of 4-nitrophenol.
Efficient catalysts for the dehydrocoupling or dehydropolymerisation of H(3)B·NMe(x)H((3-x)) (x = 1, 2) have been developed by variation of the P-Rh-P angle in {Rh(Ph(2)P(CH(2))(n)PPh(2))}(+) fragments (n = 2-5).
We report here on an efficient one-step-impregnation method to synthesize crystalline mesoporous bimetal oxides (e.g. NiFe(2)O(4), CuFe(2)O(4), Cu/CeO(2)) using mesoporous silicas as hard templates under optimized mixing conditions. This new procedure enables a true replication of the mesostructure with high yield and…
Recent developments of non-covalent functionalization of carbon nanotubes (CNTs) require a systematic understanding of the interaction between molecule and CNTs (CNT-molecular interaction); however, it has been difficult to evaluate the "net" interaction between the CNTs and molecules. We now use silica gel particles…
Studies on new antibacterial therapeutics and strategies are currently being conducted in many microbiological, pharmaceutical and biochemical laboratories. The antibacterial activity of plant-derived compounds as well as silver and gold nanoparticles is the subject of this minireview. The application of photodynamic…
Dimethyl sulfoxide (DMSO) in aqueous solution is widely used for the preservation of biological tissues under freezing conditions. DMSO and other agents are believed to act colligatively to depress the freezing point of water and, importantly, to promote the vitrification of water to prevent its crystallisation and th…
A novel seed-mediated synthetic route to produce multibranched gold nanoparticles is reported, in which it is possible to precisely tune both their size and nanostructuration, while maintaining an accurate level of monodispersion. The nanoscale control of surface nanoroughness/branching, ranging from small bud-like fe…
