Eight isostructural lanthanide coordination polymers [Ln(bptc)(phen)(H2O)]n (Ln = Dy for , Eu for , Tb for , Gd for , Sm for , Nd for , Yb for , Pr for ) were successfully prepared based on bridging asymmetric polycarboxylate ligand biphenyl-3,2',5'-tricarboxylic acid (H3bptc) and chelating 1,10-phenanthroline (phen)…
Supramolecular assemblies of fluorescent glycolipids exhibited molecular packing rearrangement as well as morphological transformation, in response to amino acid analytes. Naked-eye detectable fluorescence color changes and hydrogel formation as the result of the amplification of the molecular- and nanometer-scaled ch…
A new type of acidic macrocellular and mesoporous silica-alumina foam is obtained via a one pot alkaline sol-gel route coupled with a concentrated emulsion-based templating technique. The mixed oxide monolith exhibits high surface acidity, translating into excellent performance in the acid-catalyzed dehydration of bio…
Octahedral Fe 3 O 4 particles were synthesized through the combination of thermal decomposition with a molten salt method. F-800 exhibits excellent microwave absorption behavior with a thickness of 1.4 mm.
With the aid of ab initio calculations at the MP2 level of theory, we designed a novel class of inorganic salts, M(+)(en)3M3'O(-) (M, M' = Li, Na, and K), by using the M3'O superalkalis. These compounds are the first examples of inorganic salts wherein the superalkali occupies the anionic site, and termed superalkalid…
The self-assembly of peptide nanotubes formed by an L-glutamic acid-based bolaamphiphile is shown to proceed via a remarkable mechanism where the peptide conformation changes from β-sheet to unordered. The kinetics of this process are elucidated via X-ray scattering and UV circular dichroism methods. The reverse trans…
Sulfite is detected based on the N-GQDs for the first time and the proposed nanosensor is simple and highly selective.
Our long-term goal is to develop a hybrid cellulose-copper nanoparticle material as a functional nanofiller to be incorporated in thermoplastic resins for efficiently improving their antimicrobial properties. In this study, copper nanoparticles were first synthesized through chemical reduction of cupric ions on TEMPO…
We propose an original analog method to perform instantaneous and quantitative spectral analysis of microwave signals. An ensemble of nitrogen-vacancy (NV) centers held in a diamond plate is pumped by a 532 nm laser. Its photoluminescence is imaged through an optical microscope and monitored by a digital camera. An in…
The need for determining the instant capacity of an energy storage device has led to the integration of an indicator gauge in batteries. Consumers only have to press the contact points on the battery to activate a thermochromic indicator, which measures the heat resistance of the device. This can be implemented in a s…
Corn husk is one of the agricultural residues represent abundant, inexpensive, and readily available source of renewable lignocellulosic biomass. Cellulose nanocrystals (CNCs) were extracted from corn husk by alkali and bleaching treatments followed by sulfuric acid hydrolysis treatment. The material obtained after ea…
Traditional fiber reinforced polymer (FRP) composite that is often fabricated from single type of reinforcement has shown its ability to replace the conventional metallic material counterparts. However, due to several stringent requirements on ductility, this has affected the performance of FRP composites for the stru…
-isopropylacrylamide) reveals a reactive thiol that attacks the epoxides present across the surface of graphene oxide. The new composite material was characterised by a combination of SSNMR, FTIR, Raman, EDX, XPS, TGA and contact angle measurement; it shows enhanced thermal stability and solubility in water.
composite successfully acted as a sensing unit in a photoelectrochemical platform for antioxidant capacity evaluation in foodstuffs. The related mechanism was further unearthed and discussed in-depth. Such a straightforward yet cogent principle was also applied to our integrated device for the "smart" analysis of the…
Microwave-assisted synthesis of high surface area (SA BET = 1059 m 2 g −1 ) nanoporous hypercrosslinked polyaniline for gas storage and supercapacitor applications.
Hydrothermal synthesis in the presence of cotton led to ferrite nanoparticles displaying enhanced hyperthermia performance.
The use of PbS colloidal quantum dots in photovoltaic devices is very promising because of their simple and low cost production processes and their unique properties, such as bandgap tunability and potential multiple exciton generation. Here we report the synthesis of PbS nanocrystals used for application in solar cel…
Low-temperature (10 K) photoluminescence excitation and emission spectra of undoped Sr3SiO5 as well as Ce(3+) and Eu(3+) single doped Sr3SiO5 have been investigated. They show the host exciton band and the O(2-) to Eu(3+) charge transfer band at 5.98 eV (207 nm) and 3.87 eV (320 nm) respectively. Low-temperature therm…
Enhanced ultra-broad band emission has been demonstrated in transparent Ag/Mn 2+ codoped zinc borate glasses for a broad band light source.
A novel nanoparticle preparation technique using pulsed arc plasma deposition has been developed as a dry catalyst preparation process in complete contrast to conventional wet processes.
