For several decades LaCoO${}_{3}$ attracted interest due the unconventional thermally-driven spin-state crossover from a nonmagnetic to paramagnetic state. More recently, it was realized that the ``nonmagnetic'' ground state harbors some form of magnetism that is likely due to local magnetic entities forming at oxygen…
We study the influence of electrical poling, carried out at room temperature, on the structure and magnetism of Pb(Fe0.5Nb0.5)O3 by analyzing the differences observed in structural and magnetic properties before and after the electrical poling. The changes observed in magnetization of Pb(Fe0.5Nb0.5)O3 before and after…
Molecular dynamics simulations showed that a basal carbon nanotube can activate and guide the fabrication of single-walled carbon nanotubes (CNTs) on its internal surface by self-assembly of edge-unpassivated graphene nanoribbons with defects. Furthermore, the distribution of defects on self-assembled CNTs is controll…
This article proposes a new method of instability classification of organic peroxides (ICOP) for assessing the risk of decomposition reaction of organic peroxides, based on the adiabatic calorimetric approaches and fuzzy analytic hierarchy process (FAHP). T onset is set as instability possibility index. Maximal power…
Abstract First‐ and fourth‐generation phosphorus dendrimers decorated on their surface with (+)‐cinchonine moieties for the use as organocatalysts have been prepared. The first‐generation dendrite showed the highest activity and enantioselectivity in the α‐amination of several β‐dicarbonyl compounds. A positive dendri…
By exploiting salt formation, a new series of primary ammonium monocarboxylate salts of a nonsteroidal anti-inflammatory drug, namely, diflunisal, was synthesized. The majority of the salts thus synthesized turned out to be good gelators of various solvents, including the solvents (e.g., methyl salicylate and pure wat…
In this report, ordered lead zirconate titanate Pb(Zr0.52Ti0.48)O3 (PZT) nanodot arrays were fabricated by an original one-step mask etching route. The one-step mask etching strategy is based on the patterned nanostructure of barrier layer (BL) at the bottom of anodic aluminum oxide (AAO), by a direct transfer of the…
With growing concerns on increased waste emissions, depleting capacity for final disposal which triggered calls for new regulations on resource managements in the society, Japan PVC Pipes and Fittings Association (PPFA) started a voluntary recycling system proactively to retain flexibly in system operation and modific…
Poly vinyl alcohol (PVA) is a hydrophilic, biocompatible, and biodegradable polymer which has found application in biodrugs and tissue engineering. Sericin accompanying silk is a waste which is produced in scouring silk and has interesting properties which has attracted the attention of researchers. Silk sericin is al…
Abstract Efficiency in antimicrobial packages based on the release of active agents depends on their retention into the packaging materials and on the extent and rate of their release to the package headspace. In this work, the effects of polymer chemical composition and matrix morphology on the release of carvacrol w…
Abstract Density functional theory was used to determine selected experimentally observable properties of the and point defects in diamond. We report that the symmetry of the defects are and retrospectively with the hydrogen(s) saturating carbon radicals that are produced when the vacancy is formed. has an accessible…
ABSTRACT In this work, novel polyvinyl alcohol (PVA)/intercalated montmorillonite (MMT) nanocomposite foams were fabricated by melt extrusion with fixed amount of foaming agent, and the structure and properties were investigated with X‐ray diffraction, transmittance electron microscope, differential scanning calorimet…
Oxovanadium(IV), copper(II) and cobalt(II) acetylacetone complexes have been grafted onto amino‐modified CMK‐3‐O (VO‐NH 2 ‐CMK‐3, Cu‐NH 2 ‐CMK‐3 and Co‐NH 2 ‐CMK‐3,respectively) and the materials thus prepared were used as heterogeneous catalysts for the aerobic oxidation of styrene. X‐ray diffraction, nitrogen adsorp…
Two series of crystalline–crystalline miktoarm star polymers were prepared and their thin film morphologies were investigated in detail by synchrotron grazing incidence X-ray scattering (GIXS): poly( n -hexyl isocyanate)(5000)–poly(ε-caprolactone) 1–3 (17000) (PHIC(5k)–PCL 1–3 (17k)) and poly( n -hexyl isocyanate)(100…
Abstract We report herein an efficient one‐step synthesis of 4,6‐benzylidene glycoside derivatives from aromatic aldehydes bearing electron‐donating or ‐withdrawing groups as well as polymerisable monomer groups. Glucose, mannose and galactose derivatives could also be used successfully. Several of the glucose derivat…
Hierarchical structures (HSs) constructed by nanoparticle-based building blocks possess not only the properties of the primary building blocks but also collective properties of the assemblies. Here we report the facile preparation of hierarchical Ag nanoparticles/polyhedral oligomeric silsequioxane molecule (POSS) hyb…
In the present study, the effects of different dopants such as camphorsulfonic acid (CSA), dodecylbenzene sulfonic acid (DBSA) (70 wt% in isopropanol), and dodecylbenzene sulfonic acid sodium salt (DBSANa + ), and different solvents such as N-methylpyrrolidone (NMP), and N,N-dimethylformamide (DMF) on the structure an…
The effects of electric fields on the filler response dynamics and electrical percolation of poly(ethylene succinate)/multiwall carbon nanotube (MWCNT) composites are studied. When subjected to AC electric fields in their melt state, PESu/MWCNT composites exhibit dramatic improvements in their transverse electrical co…
Covalently attaching lanthanide complexes to the polymer backbone can effectively reduce the clustering of lanthanides and thus become an important strategy to fully unleash their potential. In this Communication, a metal-free click reaction is used for the first time to link a lanthanide complex to the polymer matrix…
PC/ABS nanocomposites have been developed using a mixture of acid functionalized multiwalled carbon nanotubes (f‐MWCNT) and aminoproply triethoxysilane‐treated cenospheres. The mechanical and flammability characteristics have been determined as per ASTM standards. The addition of a small quantity (∼1%) of MWCNT furthe…
