Metal–organic frameworks (MOFs) have enjoyed considerable interest due to their high internal surface areas as well as tunable pore geometry and chemistry. However, design of optimal MOFs is a great challenge due to the significant number of possible structures. In this work, we present a strategy to rapidly explore t…
Homogeneously alloyed bimetallic particles of AuPd with an average size of ca. 2 nm were successfully prepared by simultaneous sputter deposition of Au and Pd in an ionic liquid in the absence of any additional stabilizing agents. The chemical composition of the AuPd alloy was tunable depending on the area fraction of…
A (PNP)Co(I)methyl diamagnetic complex formally loses an H atom from the pincer ligand, exhibiting a long-range metal-ligand cooperation in what may be considered as an unusual example of 'C-H cleavage'. Spectroscopic data indicate that the product is a neutral Co(I) complex with a radical delocalized in the ligand ba…
We investigate the transport properties in a zigzag silicene nanoribbon in the presence of an external electric field. The staggered sublattice potential and two kinds of Rashba spin-orbit couplings can be induced by the external electric field due to the buckled structure of the silicene. A bulk gap is opened by the…
Distortion, residual stress and mechanical property anisotropy are current challenges in additive manufacturing (AM) of Ti–6Al–4V. High-pressure, interpass rolling was applied to linear AM parts and resulted in a change from large columnar prior β grains to a completely equiaxed microstructure with grains as small as…
In this study, preparation and characterization of soft crosslinked gelatin sponge for blood hemostasis application was considered. The effects of gelatin and crosslinker concentrations and altering freeze-drying temperature on sponges' density and structure, water absorption ability and biodegradation, cytotoxicity,…
Geopolymer Concrete (GPCs) is a new class of concrete based on an inorganic aluminosilicate binder system compared to the hydrated calcium silicate binder system of concrete. It possesses the advantages of rapid strength gain, elimination of water curing, good mechanical and durability properties and are eco-friendly…
A simplistic, elegant approach has been invoked for the gram level synthesis of cubooctahedral Zn3V2O8 without the assistance of any template or growth directing agent. By heating on a water bath, ZnSO4 and ammonium vanadate produce unique cubooctahedral Zn3V2O7(OH)2(H2O)2. Then, cubooctahedral Zn3V2O8 is generated up…
We report a new use of dendrimer-entrapped gold nanoparticles (Au DENPs) modified with folic acid (FA) as a non-viral vector for targeted gene delivery applications. In this study, amine-terminated generation 5 poly(amidoamine) dendrimers modified with FA via covalent conjugation were used as templates to synthesize g…
A novel operando UV-Vis spectroscopic set-up has been constructed and tested for the investigation of catalyst bodies loaded in a pilot-scale reactor under relevant reaction conditions. Spatiotemporal insight into the formation and burning of coke deposits on an industrial CrO(x)/Al(2)O(3) catalyst during propane dehy…
Herein, we reported a facile electrochemical method to prepare hierarchical porous CeO2 nanospheres and their implementation as highly-efficient absorbents in removing organic dyes. These hierarchical CeO2 nanospheres constructed of numerous nanocrystallites exhibit excellent performance in removing Congo red. The ads…
The integration of ZnO nanowire-based energy harvesting devices into flexible polyesters or clothes would have a significant effect on the energy harvesting building block for harvesting the mechanical energy from human motions. Moreover, the demonstration of high output power via a doping process opens an important m…
Treatment of [8]cycloparaphenylene (CPP) with the oxidant triethyloxonium hexachloroantimonate afforded an isolable radical cation of the parent carbon nanohoop. The photophysical properties of [8]CPP˙+SbCl6− were investigated, showing the presence of two absorptions at 535 nm and 1115 nm. Time-dependent density funct…
The incorporation of bio-renewable resources such as fatty acids into the polymer chain allows tailoring the properties of products, for their widespread applications. A series of methacrylate monomers with side-chain fatty acids (FAMA) were synthesized by esterification of 2-hydroxyethyl methacrylate (HEMA) and fatty…
Hydrocarbon autoignition has long been an area of intense fundamental chemical interest, and is a key technological process for emerging clean and efficient combustion strategies. Carbon-centered radicals containing an -OOH group, commonly denoted ˙QOOH radicals, are produced by isomerization of the alkylperoxy radica…
A tridentate benzoxazole-containing aminophenol ligand HL(BAP) was synthesized and complexed with Cu(II). The resulting Cu(II) complexes were characterized by X-ray, IR, UV-vis-NIR spectroscopies, and magnetic susceptibility studies, demonstrating that the ligand is oxidized to the o-iminosemiquinone form [L(BIS)](-)…
Chemiluminescence (CL), as a sensitive, rapid, and facile analytical method, has been widely applied in environmental monitoring, clinical diagnosis and food safety. Recently, the main challenge and research interest in the CL study have been focused on exploring new CL systems and obtaining new insight into the inter…
Efficient ratiometric fluorescent Fe(3+) probes were designed and synthesized by linking a conjugated naphthalene chromophore to a rhodamine platform and a lipophilic triphenylphosphonium (TPP) cation. The probes could sensitively and selectively detect mitochondrial Fe(3+) in living cells.
Results of studies on fast ignition of inertial confinement fusion (ICF) targets are reviewed. The aspects of the fast ignition concept, which consists in the separation of the processes of target ignition and compression due to the synchronized action of different energy drivers, are considered. Criteria for the comp…
We report precursor-based methods for low-temperature synthesis of two structure modifications of NaMnPO4. The maricite phase is thermodynamically more stable, while the olivine phase is of great interest as a positive-electrode material for lithium and sodium ion batteries. The advantage of synthetic procedures is th…
