Aligned macroporous monoliths of an organic cage, a polymer of intrinsic microporosity (PIM-1), and a metal-organic framework (HKUST-1) are prepared by a controlled freezing approach. In addition to macropores, all the monoliths contain the intrinsic micropores.
A new organic donor–π–acceptor sensitizer MKA253 has been applied for highly efficient solid-state dye-sensitized solar cells (ssDSSCs).
Coral-like BaTiO 3 nanostructures with good photocatalytic performances were successfully prepared through a simple hydrothermal route.
This research is aimed to develop an effective supramolecular route for tuning the surface activity of the surfactant. To this end, cationic gemini amphiphiles and cucurbit[7]uril (CB[7]) were complexed in water, and each hydrophobic chain of the gemini amphiphiles was bound with a CB[7]. The steric hindrance of CB[7]…
Monodispersed Ag nanoparticles were assembled in the channels of FDU-15 ordered mesopolymers by a simple in situ auto-reduction method and exhibited high catalytic performance in the reduction of 4-nitrophenol.
A reactive force field has been developed that is used in molecular dynamics (MD) studies of the surface transformation of the cobalt (0001) surface induced by an overlayer of adsorbed carbon atoms. Significant surface reconstruction is observed with movement of the Co atoms upward and part of the C atoms to positions…
We prepared PdO nanoflake thin films on the SiO2 substrate by reactive sputter deposition, and studied their sensing response to H2 at temperatures between 25 and 250 °C. In addition to the oxygen ionosorption model, which is used to describe the early H2 sensing response over the temperature range studied, the H2 sen…
High quality Lithium phosphate (Li 3 PO 4 ) thin films have been deposited by metal-organic chemical vapor deposition (MOCVD), using tert-butyllithium and trimethyl phosphate as precursors. The Li 3 PO 4 films deposited at 300°C yielded the highest ionic conductivity (3.9 × 10 −8 S·cm −1 ). Increasing the deposition t…
Magnetic fluctuations caused by the nuclear spins of a host crystal are often the leading source of decoherence for many types of solid-state spin qubit. In group-IV semiconductor materials, the spin-bearing nuclei are sufficiently rare that it is possible to identify and control individual host nuclear spins. This Le…
Low solubility of potent (anticancer) drugs is a major driving force for the development of noncytotoxic, stimuli-responsive nanocarriers, including systems based on amphiphilic block copolymers. In this regard, we investigated the potential of block copolymers based on 2-hydroxyethyl acrylate (HEA) and the acid-sensi…
Cube-like porous ZnSnO 3 @TiO 2 has been prepared. Furthermore, it exhibits excellent cycle stability and rate capability for LIBs.
Porous NiO nanosheets self-grown on alumina tube using a novel flash synthesis displayed wide dynamic range detection to VOC vapours.
Biofilm formation and the production of extracellular polymeric substances (EPS) by meso- and thermoacidophilic metal-oxidizing archaea on relevant substrates have been studied to a limited extent. In order to investigate glycoconjugates, a major part of the EPS, during biofilm formation/bioleaching by archaea on pyri…
A medium Mn steel has been designed to achieve an excellent combination of strength and ductility based on the TRIP (Transformation Induced Plasticity) concept for automotive applications. Following six passes of hot rolling at 850 °C, the Fe-7.9Mn-0.14Si-0.05Al-0.07C (wt.%) steel was warm-rolled at 630 °C for seven p…
Al-doping of SnO 2 photoanodes can simultaneously improve conduction band and electron lifetime of high-performance dye-sensitized solar cells.
Novel star‐like polymers are prepared via atom transfer radical polymerization (ATRP) of polyhexamethylene guanidine hydrochloride (PHMG) macromonomer and acrylamide (AM) using β‐cyclodextrin (CD) with 8‐active and 5‐active sites as a macroinitiator. The resulting star‐like polymers are characterized by gel permeation…
Due to an increasing rate of traffic volume and truckloads in recent years, asphalt binders are often modified with synthetic polymers to increase stiffness and sustain excessive heat during hot summer days. However, the cost of polymer-modified binders (PMBs) is significantly higher than unmodified binders. Nanoclays…
In this study, heterogeneous palladium catalysts supported on ordered mesoporous cobalt oxide–carbon nanocomposites were applied to the water-mediated Suzuki coupling reaction of chlorobenzene and phenylboronic acid and exhibited a high yield of biphenyl (49%) under mild reaction conditions free of phase-transfer agen…
A trivalent titanium complex combining salen ligand (salen-H 2 ═ N,N -bis(3,5-di- tert -butylsalicylidene)-1,2-benzenediamine) was synthesized as catalyst for copolymerization of CO 2 and cyclohexene (CHO). In combination with onium salt [PPN]Cl, (Salen)Ti(III)Cl showed impressive activity and selectivity, yielding co…
The continued dominance of copper in microelectronic manufacturing is due in part to the techniques that have kept pace with the relentless trend towards smaller feature sizes. Pure and defect-free copper features can be created at these and smaller scales using gas phase deposition methods such as chemical vapor depo…
