The review analyzes the patent literature dealing with metal protection by volatile corrosion inhibitors (VCIs) and materials based thereon. It has been found inhibitors of atmospheric corrosion with vapor pressure above 10 -5 mmHg can be used as VCIs, including nitrogen-containing bases of various nature, salts of ni…
Bismelamines end-functionalized with oligo(p-phenylenevinylene) self-aggregate in nonpolar solvent to form short nanorods by helical π-π stacking. This inherent self-aggregation can be guided to a supramolecular polymerization pathway by complexing with a cyanurate, leading to gel-forming elongated nanotapes lacking t…
We present a simple method to measure the cathodoluminescence of charging and non-charging phosphor powder layers at low primary electron beam energy. The method is based on comparing a non-charging surface of a conducting material such as copper or indium tin oxide with charging surfaces of non-conducting phosphors.…
Quantum dots (QDs) exhibit unique optical properties including size-tunable fluorescence, superior brightness, broad absorption and tiny emission bandwidth. These properties have made QDs promising candidates for bioimaging and biosensing applications. In this work, CdTe QDs were synthesized in aqueous phase using bot…
Single-wall carbon nanotubes (SWCNTs) grown from C60 and C70 inside SWCNTs with diameters of 1.5 ± 0.1 nm are investigated. The as-produced SWCNTs have been extracted, separated, and characterized. The products from C70 are dominated by (7,6) and (9,4) SWCNTs, whereas those from C60 are dominated by (6,5) SWCNTs.
We report the design and synthesis of pH-responsive vesicular nanoparticles (NPs) based on amphiphilic random copolymers as novel drug carriers for chemotherapy. The random copolymers were photopolymerized from acryloyl chloride, followed by assembly in acetone. The resulting vesicular PAC NPs with an acrylate-functio…
The density functional theory (DFT) was used to investigate the corrosion inhibition of three inhibitors on zinc. Quantum chemical parameters such as the energy of highest occupied molecular orbital (), the energy of lowest unoccupied molecular orbital (), energy gap , hardness , softness , electrophilicity index , th…
Solid state techniques involving pressure and temperature have been used to synthesize the fluoride member of the CuX(2)(pyrazine) (X = F, Cl, Br) family of coordination polymers that cannot be crystallized by solution methods. CuF(2)(pyrazine) exhibits unique trans doubly-bridged Cu-F(2)-Cu chains that provide an opp…
This work is concerned with the surface modification of fluorescent silica nanoparticles by a monoclonal antibody (M75) and the specific bioadhesion of such particles to surfaces containing the PG domain of carbonic anhydrase IX (CA IX), which is a trans-membrane protein specifically expressed on the surfaces of sever…
Cu–0.81 mass%Cr–0.12 mass%Zr alloy was spun into ribbon and then aged at different temperatures for different time. The microstructure, microhardness and electrical conductivity were investigated. It is found that the mother alloy ingot solidified under conventional conditions consists of three phases: Cu matrix, Cr a…
Three types of Al–Co–Ni decagonal quasicrystals in Al72.5Co11Ni16.5, Al71Co14.5Ni14.5 and Al71.5Co16Ni12.5 alloys have been examined by Cs-corrected high-angle annular detector dark-field scanning transmission electron microscopy (HAADF-STEM), which has an enough resolution to represent individual TM atoms as bright d…
A fast and green way to synthesize a free-standing and flexible silver nanoparticles–graphene (Ag NPs–GE) film with high surface-enhanced Raman scattering (SERS) sensitivity has been developed. The silver nitrate–graphene oxide (Ag+–GO) films can be fabricated through vacuum filtration of the Ag+–GO suspension. And th…
A green and reusable catalytic procedure for oxidation of pyridines to N-oxides was developed. High yields of heterocyclic N-oxides were obtained when catalyzed by Δ-Na8HPW9O34 in water at room temperature. The catalyst used in the system could be recovered and reused several times without obvious loss of activity.
Nanostructured conversion coating of Al‐Mg alloy was obtained via the surface treatment with zirconium titanium salt solution at 25°C for 10 min. The zirconium titanium salt solution is composed of tannic acid 1.00 g · L −1 , K 2 ZrF 6 0.75 g · L −1 , NaF 1.25 g · L −1 , MgSO 4 1.0 g/L, and tetra‐n‐butyl titanate (TBT…
A new series of chemically well-defined brush glycopolymers consisting of a polyoxyethylene backbone and bristles bearing glycosyl and methyl end groups was synthesized with various compositions. The glycopolymers were thermally stable up 200 °C and were soluble in a variety of common solvents. The brush polymer films…
In the present study, we describe novel lipid/nanoparticle assemblies (LNPs), consisting of a dimethyldidodecylammonium bromide (DMAB) modified poly(lactic-co-glycolic acid) (PLGA) nanoparticle core wrapped in a 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) shell. The results of cell cytotoxicity and cellular upt…
The polyborosilazane (PBSZ) was employed as the sintering additive and the dense ZrB2 ultra-high temperature ceramic samples were fabricated by hot pressing at 1900°C. The relative density of sintered ceramics is 96.4%. The PBSZ was converted to amorphous SiBCN ceramics after sintering. Mass transfer process was signi…
3-Nitrocinnamic acid (3NCA) was synthesized and its crystals were grown in aqueous solution by slow evaporation solution growth technique. The grown crystal was confirmed by powder XRD studies. The geometry, intermolecular hydrogen bonding, and harmonic vibrational wavenumbers of 3NCA were investigated with the help o…
We have developed a surface structure transfer method by use of the catalytic activity of platinum (Pt). When a Pt mesh contacts Si wafers immersed in a HF plus H 2 O 2 solution, Si oxidation and its dissolution instantaneously proceed, resulting in formation of the inverted structure of the Pt mesh on Si. The etching…
A new Co-based 3D framework has been constructed from an unprecedented 1D alternate Co5 chain and discrete linear Co3 unit as two distinct secondary building units, which exhibits slow magnetic relaxation behavior.
