Guided by DFT based modeling the chemical shift range of a hydride resonance in the proton nuclear magnetic resonance (NMR) spectrum of the intermediate-spin, square planar iron complex t Bu (PNP)Fe–H was predicted and detected as a broad resonance at −3560 ppm (295 K) with a temperature dependent shift of approximate…
We report a careful investigation of a selective phase formation in the zirconium-terephthalic acid system during solvothermal synthesis, which could result in the UiO-66 (Zr6O6(OH)4(BDC)6) or MIL-140A (ZrO(BDC)) metal-organic frameworks (MOFs). The introduction of water varies the phase from MIL-140A to UiO-66 by pro…
Phase information and spatially coherent illumination have usually been considered indispensable components of most microwave imaging systems. Dynamic metasurface apertures (DMAs)—with their ability to generate spatially incoherent illumination—have recently supplanted these assumptions in favor of simplified imaging…
Multistructural and versatile fibers have attracted enormous interests in various potential applications ranging from tissue engineering and cells to sensors. However, the controllable fabrication and nonwoven assembly of fibers remain a challenge. Here, we developed a novel strategy to in situ fabricate supramolecula…
Fully π-conjugated polycyclic hydrocarbons with antiaromatic character have attracted research attention because of their unique properties such as narrow energy gaps, and thus should find application as optical and electronic materials. Although antiaromatic 16π-electron frameworks can be constructed by the incorpora…
Au nanoparticle (NP)- and CdS quantum dot (QD)-codecorated In 2 O 3 nanosheets, assembled into flowerlike structure (In 2 O 3 /Au/CdS), were synthesized to facilitate photocatalytic H 2 production. The optimized In 2 O 3 /Au 4 /CdS-12 (4 wt % Au NPs and CdS QDs were deposited for 12 cycles) displays achieved a photoca…
A series of red-emitting thermally activated delayed fluorescence (TADF) polymers have been designed and synthesized based on poly(fluorene- co -3,3′-dimethyl diphenyl ether) (PFDMPE) as the backbone. Compared with polyfluorene (PF, 2.16 eV), the introduction of 3,3′-dimethyl diphenyl ether into the main chain of PFDM…
Ultrathin films containing polymer-grafted nanoparticles (PGNs) show promise for use in hybrid electronics and high energy density materials. In this work, we use a coarse-grained model to simulate a hexagonally packed monolayer of PGNs adsorbed on a smooth surface that is attractive to both nanoparticles and polymer…
-carbon frameworks, and nanothreads with diamond-like structures were synthesized by compressing benzene and its derivatives. Here by compressing a benzene-hexafluorobenzene cocrystal (CHCF), H-F-substituted graphane with a layered structure in the PIP product was identified. Based on the crystal structure determined…
Fabrication of porous scaffolds with great biocompatibility and osteoinductivity to promote bone defect healing has attracted extensive attention. In a previous study, novel lanthanum phosphate (LaPO 4 )/chitosan (CS) scaffolds were prepared by distributing 40- to 60-nm LaPO 4 nanoparticles throughout plate-like CS fi…
Abstract High‐performance solution‐processed metal oxide (MO) thin‐film transistors (TFTs) are realized by fabricating a homojunction of indium oxide (In2O3) and polyethylenimine (PEI)‐doped In2O3 (In2O3:x% PEI, x = 0.5–4.0 wt%) as the channel layer. A two‐dimensional electron gas (2DEG) is thereby achieved by creatin…
As a common phenomenon in biological systems, supramolecular transformations of biomacromolecules lead to specific biological functions as outputs, which thus inspire people to construct biomimetic dynamic systems through supramolecular transformation strategy. It should be noted that well-modulating the artificial ma…
Hybridization of nanostructured cobalt oxides with carbon nanotubes (CNTs) is considered to be an operative approach to harvest high-performance anode material for lithium-ion batteries (LIBs). On the other hand, there are numerous related works, most of which adopted a “post-combination” strategy, which is not only c…
A novel NaNi 0.8 Co 0.15 Al 0.05 O 2 material with a spherical architecture and layered monoclinic phase structure was prepared, which delivers remarkable capacity retention of 86.7% at 1C after 200 cycles.
The alternating copolymerization of CO 2 /epoxides to polycarbonates (CO 2 –PCs) has been an area of research focus because of the growing concern about energy and the environment. Regardless of the enormous progress that has been made, the lack of functionalities and inert chemical structure of CO 2 -based polycarbon…
We directly map the catalytic activity on metallic (1T) basal sites and semiconducting (2H) edge sites within 2D MoS 2 nanosheets.
In situ fabricated CaTiO 3 /TiO 2 heterojunction shows highly photocatalytic activity for reduction of CO 2 to CO with H 2 O.
• Transport properties of commercially available carbon felt electrodes was calculated. • Impact of pore structure and pore size distribution on permeability was shown. • Imbibition curves showing capillary pressure – saturation relationship was discussed. Carbon felt electrodes are commonly used as porous electrodes…
A small Fe3O4 nanoparticles-based T1 contrast agent was assembled into a pH- and glutathione-responsive T2-T1 switching contrast agent, Fe3O4-ZIF-8. In vivo T1-weighted images of mice showed that Fe3O4-ZIF-8 displayed darkening contrast enhancement for liver sites, while darkening to brightening contrast enhancement a…
For practical use of perovskite solar cells (PSCs) the long-term stability of devices should be ensured. The device stability is attributed to degradation of the perovskite molecule due to moisture and ion migration and thermal and light instability under sunlight illumination. To solve the stability issues, we propos…
