Despite having a good spectral response, a bis(tpy)ruthenium complex with peripheral porphyrin and phosphonate anchoring domains gives poor photoconversion efficiency due to a triplet–triplet energy transfer process.
The integration of the modified LJ-potential allowed revealing the universal effect of the open carbon tube on the molecular objects moving within or proximate to the tube. There has been established that there are modes of the molecule motion without the energy exchange with the atoms of the carbon framing, under whi…
A simple bottom-up method to fabricate novel square prism-shaped poly( o -phenylenediamine) (PoPD) hierarchical fibers.
The heat capacities of Pb2V2O7 and Pb3(VO4)2 as a function of temperature in the range 350–965 K have been studied by the differential scanning calorimetry method. The C P = f(T) curve for Pb2V2O7 is described by the equation C p = (230.76 ± 0.51) + (73.60 ± 0.50)×10-3 T − (18.38 ± 0.54)×105 T -2 in the entire tempera…
Glyme intercalation in copper-thiolate polymers is studied. The amorphous polymer network observed is significantly stronger than previously reported coinage metal-thiolate supramolecular hydrogels synthesized without glyme. Glyme chain length and water content strongly influence mechanical and optical behavior.
The hollow Si–Ni–Sn nanospheres with porous and hollow microspheric structure were fabricated via a versatile template synthesis approach followed by an in situ chemical reaction, and directly used as an anode material for lithium-ion batteries.
Peptic ulcer and gastritis are common and universal disease which affect up to 50% of the world’s adult population. Helicobacter pylori is a major cause of chronic-active gastritis and primary duodenal ulcers, and is strongly linked to gastric cancer. H. pylori induce chronic gastritis in virtually all infected patien…
The AFM chain behavior observed for (pipH)CuBr 3 is not caused by the CuBr 3 chains, but by the interchain exchanges leading to two-leg spin ladders. The Cu 2+ ions have easy-axis anisotropy, and this arises largely from the SOC of the Br − ligands.
Nano-crystal ZSM-5 was fabricated through the reflux crystallization method under atmospheric pressure and the crystallization evolutionary process was investigated utilizing DRIFT spectroscopy.
Schematic illustration of pathway to hollow titania nanospheroids.
Introduction. Paired associative stimulation (PAS) is an established technique to investigate synaptic plasticity in the human motor cortex (M1). Classically, to induce long-term depression- (LTD-) or long-term potentiation-like effects in the human M1, studies have used low frequency and long duration trains of PAS.…
Several surface activation methods such as chemical, electrochemical and plasma have been used for enhancing the electrochemical performance of carbon based electrodes for various applications. However, some of these surface activation methods may not be useful depending on the chemical and physical properties of the…
We develop a three-dimensional Eulerian--Lagrangian two phase mixture model for a gel in which fluid is represented in Eulerian coordinates and network in Lagrangian coordinates. The equations of motion and boundary conditions in their respective frames are derived using a principle of virtual power. The volume fracti…
Polycrystalline silicon on glass for photovoltaic applications is grown at low temperatures in a two-step process.
Single-crystalline octagonal LiMn 2 O 4 nanoparticles embedded in a carbon nanotube film are synthesized and used as a binder-free and self-standing cathode for lithium ion batteries.
The possibility of growing the (GaAs)1–x–y (Ge2) x (ZnSe) y alloy on GaAs substrates by the method of liquid-phase epitaxy from a tin solution–melt is shown. X-ray diffraction shows that the grown film is single-crystal with the (100) orientation and has the sphalerite structure. The crystal-lattice parameter of the f…
As a new type of material, Ti2AlNb based alloy has a broad application prospects in aerospace field due to its excellent properties such as low density, high specific strength at elevated temperature, excellent oxide and creep resistance. Many studies involving its material composition and structural properties have b…
Pt(L)(PPh 3 ) which possess significant cytotoxicity towards cancer cell lines was encapsulated in NLC prepared by melt-emulsification technique. Increase in particles size with decreasing zeta potential of nanolipid was observed when the drug amount in the formulation was increased, which is in agreement with the inc…
In this paper, an overview of the Swiss Nuclear Power Plant (NPP) activation methodology is presented and the work towards its validation by in-situ NPP foil irradiation campaigns is outlined. Nuclear Research and consultancy Group (NRG) in The Netherlands has been given the task of performing the corresponding neutro…
Given the desire for superior VOC values in PSCs, we have designed and synthesized a series of ‘medium bandgap’ donor–acceptor (D–A) copolymers containing carbazole (Cz) and quinoxaline (Qx) ( PCzDT-Qx , PCzDT-fQx , and PCzDT-ffQx ).
