A novel Raney Fe@HZSM-5 Fischer–Tropsch synthesis catalyst was synthesized via a facile one-pot strategy using an FeAl alloy as the Fe precursor and as the Al source. Aside from cracking/isomerization of heavy hydrocarbons, HZSM-5 also stabilizes Hägg carbide, resulting in excellent selectivity to gasoline fraction an…
Due to the π-conjugation of the whole molecule along with the push–pull property of a newly designed conjugated donor–acceptor porphyrin, the solution processed solar cells using the blend of the porphyrin small molecule with PC71BM exhibit a promising performance with a power conversion efficiency of up to 4.02%.
Triazolophanes have recently surfaced as a new class of shape-persistent macrocycles that bind anions. Bearing only triazole- and phenyl-derived CH hydrogen bond donors, these receptors have shown extraordinary Cl(-) binding strengths (>10(6) M(-1), CH(2)Cl(2)). The attributes of the triazolophane that are responsible…
Monodisperse ultrathin SnO₂ nanorods on nitrogen-doped graphene were firstly synthesized by a facile one-step hydrothermal strategy. The uniformed composites with high nitrogen content and ultrathin SnO₂ nanorods of 2.5-4.0 nm in diameter and 10-15 nm in length show a high reversible specific capacity, superior rate c…
SnS2 hollow microspheres and SnS2 3D nanoflake-based hollow microspheres are successfully synthesized via a one-step hydrothermal process. From the experimental results, a mechanism based on bubble-templating, self-assembling and subsequent shell evolution was proposed. These hollow spheres were tested as anode materi…
In this study, we demonstrate that Cu2ZnSn(SxSe1−x)4 nanocrystals with a tunable bandgap could be synthesized by a “hot-injection” protocol. In this protocol, metal stearates dissolved in oleylamine were injected into a hot solution of anion precursors in 1-octadecene (ODE) at a given reaction temperature. ODE, which…
Photochemical degradation at 1 sun under AM1.5G illumination was performed on six conjugated polymers and five different electron acceptors. Additionally, the respective polymer:PC60BM and P3HT:electron acceptor blends were studied, and all degradations were resolved in terms of film thickness and absorbance. A fully…
A low cost, low-temperature processable, highly efficient nickel sulfide counter electrode is demonstrated. Using the tailored, preformed nickel sulfide nanoparticles and electrostatic self-assembly, a novel counter electrode was fabricated that exceeded the efficiency of a conventional Pt-based cell.
We report the nonvolatile memory characteristics of pentacene-based organic field-effect transistors (OFET) using polystyrenepara-substituted with π-conjugated oligofluorenes (P(St-Fl)n (n = 1–3)) as chargeable polymer electrets. Effects of fluorene conjugated length on the surface structure and memory characteristics…
Binuclear rhenium(I) complexes with 1,2-bis(4,4'-methyl-[2,2']bipyridyl)-ethane and 1,2-bis(4,4'-methyl-[2,2']bipyridyl)-dodecane as bridging ligands and their mononuclear analogues have been synthesized and characterized by their spectroscopic and electrochemical properties. First reduction potentials and luminescenc…
Many drug delivery systems (DDSs) have been investigated for local targeting of malignant disease with the intention of increasing anti-tumor activity and minimizing systemic toxicity. An injectable thermosensitive hydrogel was applied to prevent locoregional recurrence of 4T1 breast cancer in a mouse model. The prese…
A polymeric gel is a cross-linked polymer network swollen with a solvent. Much of the literature concerning the constitutive response of these materials is limited to elasticity coupled with fluid permeation. We have developed a continuum-level theory to describe the coupled fluid permeation and large viscoelastic def…
A primary factor influencing catalyticversus stoichiometric behaviour of molecular main group species in homogeneous dehydrocoupling reactions is the redox stability of the metal centre. Thus, only in the case of redox-stable metals has catalytic behaviour so far been observed, through genuinely hydrogenic coupling (E…
Dye-sensitized solar cells (DSCs) show potential as a low cost alternative to silicon solar cells. Power conversion efficiencies exceeding 12% have been achieved for DSCs. Typical DSCs are based on TiO(2) nanoparticle photoanodes, which have numerous grain boundaries, surface defects and trap states as electrons trans…
The electronic band structure of halogenated germanene in the presence of spin–orbit coupling is investigated using first-principles calculations. Our results demonstrate that, compared with pure germanene, the π and π* bands of germanene adsorbed with Cl, Br and I remain crossed at the Fermi level – despite the cross…
A series of “H” type dye sensitizers with pyrrole as the conjugated bridge were synthesized, in which two pieces of N-arylpyrrole-based organic dye moieties were linked together through various aromatic rings. Interestingly, the introduced aromatic isolation group not only gave a new possibility to modify the construc…
This work presents a one-pot template-free synthesis, detailed characterization, growth mechanism and application of well-defined uniform monodisperse (BiO)2CO3 hierarchical hollow microspheres self-assembled with single-crystalline nanosheets. The synthesis was conducted by hydrothermal treatment of bismuth citrate a…
[PtL(6)X] {X = Cl or NCS and L(6) = 5-mesityl-1,3-di(2-pyridyl)-benzene} display similar luminescence in solution but, in the solid state, the packing of the molecules is different, with short PtPt interactions for X = NCS, leading to a red-shifted emission band. The effect has been used to generate OLEDs that emit sq…
The first luminescent metal-organic framework (MOF) with [Zn(6)(μ(6)-O)] cluster has been synthesized and realized for reversible sensing of small molecules.
A robust fluorescent turn-on sensor with a detection limit of 10 nM was developed for detecting sulfite anions in water and real beverage samples. For this sensitive sensor, the reaction of sulfite with the quenching moiety of the probe led to the enhanced fluorescent emission.
