Transient absorption spectroscopy and multivariate curve resolution analysis is used to demonstrate triplet state formation in low-bandgap polymer:fullerene photovoltaic blends.
Water oxidation reactions driven by visible light play an important role in solar fuel production. Recently, catalysts based on earth abundant elements, such as cobalt oxides, have been studied extensively. Out of many factors, the catalyst particle size certainly affects the photocatalytic activity. To reduce the cat…
Soluble copper-based M4L4 lantern-type metal-organic cages bearing internal amines were synthesized. The solution state integrity of the paramagnetic metal-organic cages was demonstrated using NMR, DLS, MS, and AFM spectroscopy. 1D supramolecular pillars of pre-formed cages or covalent host-guest complexes selectively…
This paper analyzes the impact of the use of a radical scavenger on organic films generated by aryldiazonium electrografting in terms of thickness, morphology and chemical composition. Glassy carbon (GC) and pyrolyzed photoresist films (PPFs) were modified by electrochemical reduction of 4-nitrobenzenediazonium salt i…
Nanostructured metals are a promising class of biomaterials for application in orthopedics to improve the mechanical performance and biological response for increasing the life of biomedical implants. Surface mechanical attrition treatment (SMAT) is an efficient way of engineering nanocrystalline surfaces on metal sub…
Electroforming and resistive switching data are presented and models are given addressing the unusual operating features of SiO 2 resistive memory.
Sulfurized carbon nanotubes (SCNT) with a high sulfur content (68%) have been produced with a unique method. Li–S cells comprised of the developed SCNT cathodes presented a long cycle life exceeding 1300 cycles and an extremely low capacity decay rate (0.025% per cycle) at 1/3 C rate. Moreover, their Coulombic efficie…
Core–shell HMX@TATB composites with low shell content and compact shell structure were fabricated via a facile and effective spray-drying technique.
The organic-inorganic hybrid material of polyaniline/titanium(IV) (PANI/Ti(HPO4)2) was synthesized by an oxidative polymerization reaction. The PANI/Ti(HPO4)2 was applied to remove Re(VII). The size of Ti(HPO4)2 nanoplates has no obvious effect on the sorption capacity. The effects of various environmental factors (su…
Spatially-confined electrochemical reactions are firstly realized in a highly dense nanocomposite anode for high performance lithium ion batteries.
Nanoporous silicon has been prepared through the air-oxidation demagnesiation of Mg2Si at 600 °C for 10 hours (Mg2Si + O2 → Si + MgO), followed by HCl washing. Mg2Si was prepared from 200 mesh commercial Si at 500 °C for 5 h in an autoclave. The as-prepared Si exhibits a reversible capacity of 1000 mA h g(-1) at 36 A…
A series of palladium( ii ) persistent radical carbene complexes, [PC˙(sp 2 )P]PdX (X = Cl, Br, I), was synthesized from the nucleophilic carbene [PC(sp 2 )P]PdPMe 3 .
Porous graphitic carbon nitride (pg-C 3 N 4 ) synthetized by pyrolysis of urea was hybridized with Ag-doped Fe 2 O 3 to form a visible-light-driven photocatalyst pg-C 3 N 4 /Ag/Fe 2 O 3 via a simple chemical adsorption method.
By one-step carbonization, metal organic frameworks (MOFs) can be conveniently turned into hierarchical hybrid materials which exhibit versatile functionalities.
High efficiency blue fluorescent organic light-emitting diodes were developed by using a blue delayed fluorescent emitter as a sensitizer.
The tetradentate N,N'-diethyl-N,N'-ditolyl-2,9-diamide-1,10-phenanthroline (Et-Tol-DAPhen) ligand with hard-soft donor atoms has been demonstrated to be promising for the group separation of actinides from highly acidic nuclear wastes. To identify the formed complexes of this ligand with actinides and lanthanides, ele…
Ag( i )-substitution at the Cu sites in a CuGaS 2 photocatalyst with a p-type character was a useful strategy to improve its photocatalytic and photoelectrochemical performances.
The catalyst life of Mo/zeolites is extended by short reaction–regeneration cycles. This protocol allows maximization of benzene productivity. Catalyst carburation during the activation step is shown to be key to optimum performance.
