Different metallic materials have different polarization characteristics as dictated by the open circuit potential, breakdown potential, and passivation potential of the material. The detection of these electrochemical parameters identifies the corrosion factors of a material. A reliable and well-functioning corrosion…
A push–pull porphyrin dimer with multiple electron-donating groups has been synthesized as a sensitizer with an excellent light-harvesting ability in the near-infrared region for dye-sensitized solar cells (DSSCs). The DSSC based on the sensitizer exhibited the photocurrent generation exceeding a wavelength of 900 nm,…
Mallomonas distinguenda sp. nov. and Mallomonas skvortsovii sp. nov. are described from Dak Lua swamp, located in Cat Tien National Park (Dong Nai Province, Southeastern Viet Nam). The description is based on silica-scale morphology studied by means of transmission and scanning electron microscopy. These species belon…
Surface engineering of electrode materials to yield favorable electrochemical performance is a hot spot of current research in the energy storage area. Here, this Report highlights recent progress in rational surface engineering strategies in association with their effects on the electrochemical properties. The electr…
Improving the lifetime and the operational and thermal stability of organic thin‐film materials while maintaining high conductivity and mechanical flexibility is critical for flexible electronics applications. Here, it is reported that highly conductive and environmentally stable organic transparent electrodes (TEs) c…
The unicellular cyanobacterium Cyanothece sp. CCY 0110 is a highly efficient producer of extracellular polymeric substances (EPS), releasing up to 75% of the polymer to the culture medium. The carbohydrate polymer released to the medium (RPS) was previously isolated and characterized; it is composed of nine different…
A wireless inductive heating system for thermal treatment is demonstrated using ultrastretchable liquid-metal-cored fibers. Incorporated in a wristband for alleviating pain during workplace computer use, the heater is able to both heat by up to 15 °C at 0.7 W input power and maintain electrical performance to 100% str…
Stem-cell based therapy is an emerging therapeutic approach for ischemic stroke treatment. Bone marrow stromal cells (BMSCs) are in common use as a cell source for stem cell therapy and show promising therapeutic outcomes for stroke treatment. One challenge is to develop a reliable tracking strategy to monitor the fat…
GTP and branched-chain amino acids (BCAAs) are metabolic sensors that are indispensable for the determination of the metabolic status of cells. However, their molecular sensing mechanism remains unclear. CodY is a unique global transcription regulator that recognizes GTP and BCAAs as specific signals and affects expre…
Abstract A series of gold acetonitrile complexes [Au(NCMe)2]+[WCA]− with weakly coordinating counterions (WCAs) was synthesized by the reaction of elemental gold and nitrosyl salts [NO]+[WCA]− in acetonitrile ([WCA]−=[GaCl4]−, [B(CF3)4]−, [Al(ORF)4]−; RF=C(CF3)3). In the crystal structures, the [Au(NCMe)2]+ units appe…
A combination of three innovative materials within one hybrid structure to explore the synergistic interaction of their individual properties is presented. The unique electronic, mechanical, and thermal properties of graphene are combined with the plasmonic properties of gold nanoparticle (AuNP) dimers, which are asse…
Abstract The engineering of nanoarchitectures to achieve tailored properties relevant for macroscopic devices is a key motivation of organometallic surface science. To this end, understanding the role of molecular functionalities in structure formation and adatom coordination is of great importance. In this study, the…
A novel [2]rotaxane was constructed that has a bidentate N,N'-chelate as part of a rigid, H-shaped axle and a 24-membered crown ether macrocycle containing six ether O-atoms and an olefinic group as the wheel. This unique topology produces a ligand with the ability to dial-up different donor sets for complexation to m…
With the introduction of the cation ratio of soil stability (CROSS) to replace the sodium adsorption ratio (SAR) on the basis of differential effects of K and Mg to Na and Ca, respectively, there is a requirement for a similar index involving these cations to replace the exchangeable sodium percentage (ESP). The excha…
2,5‐furandicarboxylic acid (FDCA) is a potential non‐phthalate based bio‐renewable substitute for terephthalic acid‐based plastics. Herein, we present an investigation of the oxidation rate of 5‐hydroxymethylfurfural (HMF) to FDCA in acetic acid medium using Co/Mn/Br catalyst. Transient concentration profiles of the r…
Graphene and its derivative, because of their unique physical, electrical and chemical properties, are an important class of nanomaterials being proposed as foundational materials in nanomedicine as well as for a variety of industrial applications. A major limitation for graphene, when used in biomedical applications,…
A sacrificial template strategy is developed for the synthesis of yolk-shell Au@ZIF-8 nanoreactor. The Au@ZIF-8 nanoreactor possesses single-crystalline metal-organic framework (MOF) shell with intrinsic monodisperse micropores and introduced macropores. In each of the macropores, one Au NP is encapsulated to form a n…
Abstract With a notable advantage in terms of capacity, molybdenum disulfide has been considered a promising anode material for building high‐energy‐density lithium‐ion batteries. However, its intrinsically low electronic conductivity and unstable electrochemistry lead to poor cycling stability and inferior rate perfo…
