4 agosto, 2017 - 00:00

Inkjet Printing of GaPd2 into Micro‐Channels for the Selective Hydrogenation of Acetylene

Print it! Different inks containing intermetallic GaPd2 nanoparticles were formulated and applied by inkjet printing into micro-structured reaction channels resulting in thin and homogeneous layers. GaPd2/&#x3B1;-Al2O3 showed excellent activity and selectivity for the semi-hydrogenation of acetylene.

Low‐Cost Perovskite Solar Cells Employing Dimethoxydiphenylamine‐Substituted Bistricyclic Aromatic Enes as Hole Transport Materials

Bridge to success: We report the synthesis of three new hole transport materials (HTMs) using a cost-effective procedure and the impact of different atoms in heteromerous bistricyclic aromatic ene scaffolds. S-bridged KR374 shows a a significantly improved hole-drift mobility leading to enhanced photovoltaic performance in mixed-ion perovskite solar cells and reduced hysteresis owing to the improved interface between the perovskite and HTM caused by stronger Pb–S interaction.

Sulfur‐Doped Graphene Oxide Quantum Dots as Photocatalysts for Hydrogen Generation in the Aqueous Phase

Let the sun shine: A metal-free and inexpensive catalyst, sulfur-doped graphene oxide quantum dots, is developed for efficient photocatalytic H2 production in pure water. Under direct sunlight irradiation, high initial H2 production rates in pure water and in 80 % ethanol aqueous solution indicate great potential in the development of sustainable and environmentally friendly photocatalysts for efficient H2 generation from water splitting.

Enhanced Interfacial Charge Transfer on a Tungsten Trioxide Photoanode with Immobilized Molecular Iridium Catalyst

3 agosto, 2017 - 00:00

Enhanced Interfacial Charge Transfer on a Tungsten Trioxide Photoanode with Immobilized Molecular Iridium Catalyst

A modified photoanode: An iridium complex is immobilized on a WO3 electrode to construct a composite photoanode for photoelectrochemical (PEC) water splitting. The photoanode shows a significant improvement both in photocurrent and faradaic efficiency. Kinetic studies reveal that the molecular iridium catalyst exhibits a different interfacial charge-transfer mechanism on the WO3 photoanode for PEC water oxidation compared to iridium oxide.

Electronic Transport of MoS2 Monolayered Flakes Investigated by Scanning Electrochemical Microscopy

Connected or not? Scanning electrochemical microscopy is introduced as a tool to investigate molybdenum disulfide in a straightforward fashion, providing localized information regarding the electronic transport within CVD-grown crystalline MoS2 single layers having micrometric sizes. The investigations show that there is a very large diversity of electrical connections between flakes.

Investigating Structural Requirements for the Antiproliferative Activity of Biphenyl Nicotinamides

Stopping the cell cycle: The screening of a small library of trimethoxybenzoic and nicotinic acid anilides, previously studied as P-gp modulators, allowed us to identify some N-biphenyl nicotinoyl anilides that show very interesting antiproliferative activities. The next hit refinement by a bioisosteric approach led us to observe potent antiproliferative activity of the cyano derivative 36 against MCF-7 and MDA-MB-231 cell lines.

Bridging Pharmaceutical Chemistry with Drug and Nanoparticle Targeting to Investigate the Role of the 18‐kDa Translocator Protein TSPO

Ligand logistics: Compounds with high affinity and selectivity for the 18-kDa mitochondrial translocator protein (TSPO) are useful for intracellular drug and nanoparticle targeting. The number of identified structurally distinct TSPO ligands has increased in recent years, highlighting our growing understanding of the roles of TSPO in normal and pathological conditions. This review summarizes some examples of drug delivery systems characterized by TSPO-targeting compounds.

 A New Member of the Family of &#x3C0;‐Extended TTF Stable p‐Type Semiconductors

A new member of the &#x3C0;-expanded TTF family, dinaphthotetrathiafulvalene bisimide, is proven to be an air-stable p-type semiconductor. The hole-carrier mobility of the organic field-effect transistor of the film was improved from 3.7×10−3 cm2 V−1 s−1 to 0.30 cm2 V−1 s−1 under ambient conditions by raising the substrate temperature from 25 to 200 °C during sublimation, because of the acceleration of end-on packing from a mixture of face-on, edge-on and end-on packing. More information can be found in the Communication by H. Yamada et al. (DOI: 10.1002/chem.201702657).

Catalytic Functionalization of Styrenyl Epoxides via 2‐Nickela(II)oxetanes

Nickel squares up: Low-valent nickel(0) is shown to isomerize styrenyl epoxides to aldehydes in high yields. Mechanistic studies indicate that these isomerizations occur via 2-nickelaoxetane intermediates. Catalytic hydroboration of styrene oxide with HBpin was also demonstrated to be facile.

Facilitating Active Species Generation by Amorphous NiFe‐Bi Layer Formation on NiFe‐LDH Nanoarray for Efficient Electrocatalytic Oxygen Evolution at Alkaline pH

Amorphous layer: A core-shell NiFe-LDH@NiFe-Bi nanoarray on carbon cloth (NiFe-LDH@NiFe-Bi/CC) behaves as a superior OER electrocatalyst with strong durability in alkaline media. It only requires an overpotential of 294 mV to drive 50 mA cm−2; 116 mV less than that needed by NiFe-LDH/CC.

Base-Mediated Generation of Ketenimines from Ynamides: Direct Access to Azetidinimines by an Imino-Staudinger Synthesis

3 agosto, 2017 - 00:00

 Direct Access to Azetidinimines by an Imino‐Staudinger Synthesis

Base Jump: Under strongly basic conditions ynamides gave highly reactive ketenimines that could be trapped with imines in a [2+2] cycloaddition. This imino-Staudinger synthesis led to a variety of imino analogues of &#x3B2;-lactams, namely azetidinimines (20 examples), that could be further functionalized through a broad range of transformations.
