Benzyl alcohol was oxidized by an “in situ generated” hydrogen peroxy species, formed from a dilute mixture of hydrogen and oxygen, under mild conditions at a high rate over gold, palladium and gold–palladium nanoparticles supported on hierarchical titanium silicate materials. Hierarchical TS-1 supports were obtained…
The present study aimed at developing a strategy to improve the volumetric production of PHAs by Pseudomonas fluorescens S48 using waste frying oil (WFO) as the sole carbon source. For this purpose, several cultivations were set up to steadily improve nutrients supply to attain high cell density and high biopolymer pr…
A method for the synthesis of metal nanoparticle coatings for plasmonic solar cells which can meet large scale industrial demands is demonstrated. A UV pulsed laser is utilized to fabricate Au and Ag nanoparticles on the surface of polymer materials which form the substrates for plasmonic organic photovoltaic devices…
Porous organic polymers bearing metal-catecholate groups were evaluated for their ability to remove airborne ammonia, cyanogen chloride, sulphur dioxide, and octane by micro-breakthrough analysis. For ammonia, the metal-catecholate materials showed remarkable uptake under humid conditions.
The atomistic nucleation sites of Pt nanoparticles (Pt NPs) on N-doped carbon nanotubes (N-CNTs) were investigated using C and N K-edge and Pt L3-edge X-ray absorption near-edge structure (XANES)/extended X-ray absorption fine structure (EXAFS) spectroscopy. Transmission electron microscopy and XANES/EXAFS results rev…
The electromechanically and mechano-electrically active three-layered laminate composed of a Nafion membrane, carbide-derived carbon-based electrodes, and a 1-ethyl-3-methylimidazolium trifluoromethanesulphonate ionic liquid electrolyte responds to humidity gradient and can therefore serve as a differential humidity s…
Herein, we report on a scalable synthesis of surfactant-free Bi2Te2.7Se0.3 nanocrystals by chemical exfoliation and subsequent spark plasma sintering to fabricate nanostructured thermoelectric bulk materials. The exfoliated n-type Bi2Te2.7Se0.3 nanoplatelets were shown to transform into nanoscroll-type crystals (∼5 nm…
A series of meso-pyridyl substituted BODIPY molecules has been synthesized, characterized and their optical and electrochemical properties compared. By utilizing ethanol and dichloromethane during the initial condensation reactions, there is a significant increase in the isolated yields compared to standard protocols.…
Herein, we report a novel solution processable fluorenone based small molecule with an Aggregation Induced Emission Enhancement (AIEE) property. In contrast to previous reports, the presence of the fluorenone moiety in FF triggers the AIEE property.
Halogen ions (I(-), Br(-), Cl(-)) were added into a colloidal solution of CdSe and PbS quantum dots (QDs) to form QDs capped with these inorganic ligands. Halogen ions attached to QDs through electrostatic interactions and the varying coordination strength between the inorganic ligands and QDs led to different degrees…
A hierarchically ordered 4,4′-biphenylene-bridged mesoporous organosilica framework (Bp-PMO) has been synthesized with the aim of using it as a new hybrid host for LnIII ions. A series of novel organic–inorganic luminescent hybrid materials have been obtained by covalently linking LnIII complexes (Ln = Eu, Gd, Tb, Er,…
A cold water soluble, biobased polymer derived from autoxidized soya oil has been described. Oxidized soya oil polymer was obtained by exposure to air under daylight at room temperature. The thickness of the soya oil at the beginning of the reaction and the oxidation time adversely influenced the molecular weight of t…
Solvent recovery is a big challenge for industrial-level production of ultrathin fibers by solution electrospinning because more than 70 wt% of the precursor solution is volatilizable organic solvent. In this paper, we report an interesting solventless electrospinning technique for the fabrication of poly(ethyl-2-cyan…
The healing efficacy of solution-based healing agents for a furan-functionalized epoxy–amine thermoset was investigated. In particular the effects of multimaleimide (MMI) structure and solvent type on healing behaviour were explored. Two major modes of healing are observed: Diels–Alder bonding across the crack surface…
In this work we reported an enzyme-assisted nanoparticle crosslinking (EANC) strategy to enhance the mechanical stability of peptide-based supramolecular hydrogels by more than 3000 times.
Triptycene-derived macrotricyclic polyether was proved to be an efficient “molecular glue” for cross-linking the copolymer containing dibenzylammonium salts to form supramolecular polymer networks via host–guest complexation, which was evidenced by 1H NMR spectroscopy, solution viscometry, and formation of transparent…
Single-crystal strontium titanate (SrTiO3) nanosheets have been synthesized via a solvothermal reaction route with ethylene glycol (EG) as reaction medium solvent. The as-synthesized SrTiO3 products were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and high resolu…
This work deals with the vibrational spectroscopy of O-Anisic acid (OAA) and Anisic acid (AA). The fundamental vibrational frequencies and intensity of vibrational bands were evaluated using density functional theory (DFT) with standard B3LYP/6-31G** method and basis set combinations. The vibrational spectra were inte…
Periodic density functional theory (DFT) calculations have been performed to systematically investigate the effect of reaction intermediate on catalytic activity for hydrazine (N2H4) decomposition on Rh(111). Reaction mechanisms via intramolecular and NH2-assisted N2H4 decompositions are comparatively analyzed, includ…
Magnesium alloys containing long-period-stacking ordered (LPSO) phases have attracted considerable attention because they have been reported to exhibit excellent mechanical properties, including high strength and reasonable ductility. It is thought that the LPSO phase plays a critical role in producing these favorable…
