ABSTRACT Microcrystalline cellulose (MCC) and its oxidized product dialdehyde cellulose (DAC) were introduced as the reinforcing filler in epoxidized soybean oil (ESO) thermosetting polymer. The composites comprising up to 25 wt % cellulose fillers were obtained via a solution casting. The reinforcing effects of the c…
Hybrid nanocomposites are multifunctional materials and their properties are the consequence of molecular interaction between inorganic and organic phases. These materials are interesting hosts for lanthanide ions, such as Eu3+. The purpose of this research was to synthesize Eu3+ doped SiO2–PMMA hybrid nanocomposites…
Layered double hydroxides (LDHs) have intercalation properties and are used in various applications. The performances of the LDH materials can be improved by controlling crystal morphology. Morphology of inorganic crystals is controlled by organic molecules in biomineralization. Inspired by biomineralization, we inves…
A series of mononuclear Cu(I)–halide complexes, [CuX(PPh 3 ) 2 (L)] (X = Cl − , Br − , I − ; PPh 3 = triphenylphosphine; L = pyridine (py), isoquinoline (iq), 1,6-naphthyridine (nap)), were synthesized. The emission color of [CuX(PPh 3 ) 2 (L)] varies from blue to red by changing the L ligands and the halide ions, and…
A series of cardo poly(ether ketone imide)s (PEKI-C) containing large-volume bulky phthalide groups were prepared by aromatic nucleophilic substitution reaction of commercially available phenolphthalein and 4,4′-bis(4-fluorophthalimido)diphenyl ether/4,4′-difluorobenzophenone. The glass transition temperatures (Tgs) i…
Recent advances in quantum mechanical (QM)‐based molecular dynamics (MD) simulations have used machine‐learning (ML) to predict, rather than recalculate, QM‐accurate forces in atomic configurations sufficiently similar to previously encountered ones. Here, we discuss how ML approaches can be deployed within large‐scal…
ABSTRACT Polyethylene (PE) extrusion coating on paper substrates are the traditional packing material for coffee cups and take‐out food containers. It is difficult to recycle the PE/paper laminates and the thin polymer films remain in landfills after the decomposition of their paper substrates. Disposal of plastic mat…
This paper investigates the residual stresses and interfacial shear strength of a TiAlN coating on Zr–Nb–Sn–Fe alloy (ZIRLO™) substrate designed to improve corrosion resistance of fuel cladding used in water-cooled nuclear reactors, both during normal and exceptional conditions, e.g. a loss of coolant event (LOCA). Th…
ABSTRACT The graphene oxide (GO) was prepared by sonication‐induced exfoliation from graphite oxide, which was produced by oxidation from graphite flakes with a modified Hummer's method. The GO was then treated by hydrazine to obtain reduced graphene oxide (rGO). On the basis of the characterization results, the GO wa…
The selection of a solvent or a solvent system is a fundamental and a crucial step in spinning fibres using a selected process. Solvent selection determines the critical minimum polymer concentration and the critical minimum chain entanglement which allows the spinning of nanofibres rather than other hybrid morphologi…
ABSTRACT The aim of this study was to develop stable and porous poly(ethylene oxide) (PEO)–polycaprolactone blended and silver nanoparticle (Ag NP) incorporated composite nanofiber scaffolds as antibacterial wound dressings. A facile approach for the in situ synthesis of Ag NPs was explored. In this synthesis method,…
Well-known effects of mechanical stiffness degradation under the influence of point defects in macroscopic solids can be controversially reversed in the case of low-dimensional materials. Using atomistic simulation, we showed here that a single-layered graphene film can be sufficiently stiffened by monovacancy defects…
Bilayer (BL) MoSe2 films grown by molecular-beam epitaxy (MBE) are studied by scanning tunneling microscopy and spectroscopy (STM/S). Similar to monolayer (ML) films, networks of inversion domain boundary (DB) defects are observed both in the top and bottom layers of BL MoSe2, and often they are seen spatially correla…
The authors of the title paper (Spectrochim. Acta 79A (2011) 340-343) report the crystal growth of cadmium manganese thiocyanate CdMn(SCN)4 and its characterization by single crystal X-ray diffraction and infrared spectrum. Many points of criticism, concerning the crystal growth and reported experimental data are high…
The differing binding preferences of the hydrogen tartrate ligand (HC4H4O6)- namely μ7-octadentate mode for potassium ion and bidentate mode for cupric ion rules out the doping (incorporation) of any Cu(II) ion into the crystal structure of potassium hydrogen tartrate. Hence, the claim of growth of copper doped potass…
This paper aimed to clarify whether maternal inhalation of engineered nanoparticles (NP) may constitute a hazard to pregnancy and fetal development, primarily based on experimental animal studies of NP and air pollution particles. Overall, it is plausible that NP may translocate from the respiratory tract to the place…
The search for stable polymeric nitrogen and polynitrogen compounds has attracted great attention due to their potential applications as high-energy-density materials. Here we report a theoretical prediction of an interesting LiN5 crystal through first-principles calculations and unbiased structure searching technique…
Abstract The pathogenesis of the cardiovascular system is often associated with dysfunction of soluble guanylate cyclase (sGC), which can be stimulated in both an NO‐dependent and ‐independent manner. It was previously reported that PPIX and its amphiphilic derivatives markedly activate the enzyme. To date, all porphy…

Abstract We report the synthesis of a new carbon material—diamond-like carbon film codeposited with 1% C60 molecules—by plasma-assisted chemical vapor deposition. The synthesized films exhibited strong iridescent colors after being exposed to an atmosphere containing water vapor. An electron microscopy examination rev…
