Optical sensing plays an important role in theranostics due to its capability to detect hint biochemical entities or molecular targets as well as to precisely monitor specific fundamental psychological processes. Rare-earth (RE) doped upconversion nanoparticles (UCNPs) are promising for these endeavors due to their un…
A conical intersection seam is behind the restriction of intramolecular rotation mechanism for aggregation induced emission in diphenyl dibenzofulvene (DPDBF). In solution, the seam is accessed through rotation around the exocyclic fulvene bond, leading to radiationless decay to the ground state. In the solid, the sea…
Surface-enhanced Raman scattering (SERS) spectra of 4-mercaptobenzoic acid (4-MBA) have been investigated on the surface of Cu2O nanospheres. The SERS signals were believed to originate from the static chemical enhancement, resonant chemical enhancement and electromagnetic enhancement. The coupling between the adsorba…
The biodegradable thermoplastic poly(lactic acid) (PLA) that has restricted its application due to its high brittleness and poor crystallization behavior. Toughness properties of PLA can be developed by blending with natural rubber (NR) and epoxidized natural rubber (ENR). Blending PLA with NR and ENR were prepared at…
Graphyne, a two-dimensional carbon allotrope like graphene but containing doubly and triply bonded carbon atoms, has been proven to possess amazing electronic properties as graphene. Although the electronic, optical, and mechanical properties of graphyne and graphyne nanoribbons (NRs) have been previously studied, the…
Due to their tunable surface plasmon and photothermal effects, gold nanorods (AuNRs) have proved to be promising in a wide range of biomedical applications such as imaging, hyperthermia therapy and drug delivery. All these applications can be remotely controlled by near infrared (NIR) light which can penetrate deep in…
Doping ordered mesoporous carbon with electron-donating nitrogen and sulfur heteroatoms is a promising strategy to enhance its electrochemical performance. Here we demonstrate the successful fabrication of nitrogen and sulfur co-doped ordered mesoporous carbon (NSOMC) materials with high specific surface areas (978–10…
BACKGROUND: The uptake of nanoparticles (NPs) by cells remains to be better characterized in order to understand the mechanisms of potential NP toxicity as well as for a reliable risk assessment. Real NP uptake is still difficult to evaluate because of the adsorption of NPs on the cellular surface. RESULTS: Here we us…
Over years, mathematicians, biologists and chemists have capitalised on the highly useful concept of orthogonality for developing sophisticated complex systems. The use of orthogonal pairs ensures that any modification made on one pair does not propagate any effect onto the other. While the concept equally pertains to…
The thermoelectric properties of a unique hybrid polymer-inorganic nanoparticle system consisting of tellurium nanowires and a conducting polymer, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), can be optimized by both controlling the shape of the nanoparticles and the loading and doping of the p…
Layered double hydroxides (LDHs) have been intensively studied for high-temperature CO2 capture. However, big differences in the CO2 capture capacity, ranging from 0.28 to 0.6 mmol g−1, have often been reported for the same Mg–Al–CO3 LDH. Furthermore, how the active Mg–O species that are responsible for CO2 adsorption…
This paper reports the successful preparation of Mg-doped VO2 nanoparticles via hydrothermal synthesis. The metal-insulator transition temperature (T(c)) decreased by approximately 2 K per at% Mg. The Tc decreased to 54 °C with 7.0 at% dopant. The composite foils made from Mg-doped VO2 particles displayed excellent vi…
NiMoO4 nanowires (NWs) supported on Ni foam were fabricated via a template-free hydrothermal route, and could be directly used as integrated electrodes for electrochemical capacitors (ECs). Such unique integrated architectures exhibited remarkable electrochemical performance with high capacitance, excellent rate capab…
This review provides a critical overview of the recent methods and processes developed for the production of cellulose nanoparticles with controlled morphology, structure and properties, and also sums up (1) the processes for the chemical modifications of these particles in order to prevent their re-aggregation during…
The high degree of microbial diseases and their multidrug resistant properties make the researchers to develop new class of antimicrobial agents. A modern and innovative approach of drug development is the use of metallic nanoparticles as new formulations of antimicrobial agents. In this study, microwave irradiated Ca…
BACKGROUND: Inhalation exposure studies of mice were conducted to determine if multi-walled carbon nanotubes (MWCNT) distribute to the tracheobronchial lymphatics, parietal pleura, respiratory musculature and/or extrapulmonary organs. Male C57BL/6 J mice were exposed in a whole-body inhalation system to a 5 mg/m3 MWCN…
Adamantane substituted with two to four 4-cyanophenyl groups was used for preparation of a new series of robust Porous Covalent Triazine-based Framework (PCTF) materials. Novel adamantane PCTFs were synthesized in good yields (>80%) by the trimerization reaction of 1,3-bis-, 1,3,5-tris- and 1,3,5,7-tetrakis(4-cyanophe…
The archaeon Haloferax mediterranei was selected for production of PHA co- and terpolyesters using inexpensive crude glycerol phase (CGP) from biodiesel production as carbon source. CGP was assessed by comparison with the application of pure glycerol. Applying pure glycerol, a copolyester with a molar fraction of 3-hy…
BACKGROUND: Prior studies have demonstrated a rapid and progressive acute phase response to bolus aspiration of multi-walled carbon nanotubes (MWCNTs). In this study we sought to test the hypothesis that inhalation exposure to MWCNT produces a fibrotic response and that the response is chronically persistent. To addre…
In the flexible devices' fabrication, highly ordered nanoscale texturing such as semiconductor metal oxide nanorod arrays on the flexible substrates is critical for optimal performance. Herein, a simple and general hydrothermal route has been developed to result in a large-scale growth of ZnO nanorod arrays on double…
