Switching CO Electroreduction toward Ethanol by Delocalization State-Tuned Bond Cleavage.

The electrochemical CO reduction reaction by copper-based catalysts features a promising approach to generate value-added multicarbon (C) products. However, due to the unfavored formation of oxygenate intermediates on the catalyst surface, the selectivity of C alcohols like ethanol remains unsatisfactory compared to that of ethylene. The bifurcation point (i.

Hydrophobic Composite Foams with Asymmetric Gradient Sandwich Structure for Excellent Electromagnetic Interference Shielding and Photothermal Response.

The evolution of contemporary electronics urgently requires the use of versatile electromagnetic interference (EMI) shielding materials in complex environments. Interlayer polydimethylsiloxane (PDMS)/FeO@multiwalled carbon nanotubes (MWCNTs) foams were prepared by a simple physical foaming method with excellent flexibility and electromagnetic wave absorption. The bottom nickel aramid paper (NiP) layer creates a dense conductive network by chemical plating technology, which ensures excellent EMI effectiveness.

Interfacial Water Tuning by Intermolecular Spacing for Stable CO Electroreduction to C Products.

Electroreduction of CO to multi-carbon (C ) products is a promising approach for utilization of renewable energy, in which the interfacial water quantity is critical for both the C product selectivity and the stability of Cu-based electrocatalytic sites. Functionalization of long-chain alkyl molecules on a catalyst surface can help to increase its stability, while it also tends to block the transport of water, thus inhibiting the C product formation. Herein, we demonstrate the fine tuning of interfacial water by surface assembly of toluene on Cu nanosheets, allowing for sustained and enriched CO supply but retarded water transfer to catalytic surface.

Investigation on the upconversion luminescence and ratiometric thermal sensing of SrWO:Yb/RE (RE = Ho/Er) phosphors.

SrWO phosphors doped with Ho(Er)/Yb are successfully prepared by a high temperature solid-state reaction method. The upconversion (UC) luminescence properties of all the samples have been investigated under 980 nm excitation. Strong green emissions are obtained in the SrWO:Yb/Ho and SrWO:Yb/Er samples with the naked eyes.

Constructing high sensitivity thermometry with dual-emitting Nd/Er/Yb codoped BaWO single crystal material.

Inorganic oxides doped with rear earth(RE) have attracted much interest because of their outstanding optical properties. In this paper, the BaWO:Yb/Er/Nd phosphors were successfully prepared by typical solid state method. The crystalline structure of the samples was characterized through X-ray diffraction(XRD).

Efficient upconversion emission and high-sensitivity thermometry of BaInO:Yb/Tm/RE (RE = Er, Ho) phosphor.

BaInO:Yb/Tm/RE (RE = Er, Ho) upconversion (UC) phosphors were synthesized the sol-gel method. Rietveld refinement based on XRD data proved that In ions were replaced by rare earth (RE) ions. Under 980 nm excitation, UC and optical temperature-sensing properties were investigated, and the results indicated that the samples demonstrated high UC emission efficiencies and bright emission visible to the naked eye.

Genome-wide identification, characterisation and expression analysis of the ALAS gene in the Yesso scallop (Patinopecten yessoensis) with different shell colours.

Porphyrins, one of the most common shell pigments, are by-products of the haem pathway. 5-Aminolaevulinate synthase (ALAS) is the first and rate-limiting enzyme in this pathway and has been well studied in vertebrate species. However, the function of ALAS in shell colouration has been poorly studied in molluscs, which are renowned for their colourful shells.

Effects of dietary supplementation of probiotic Shewanella colwelliana WA64, Shewanella olleyana WA65 on the innate immunity and disease resistance of abalone, Haliotis discus hannai Ino.

The effects of dietary administration of two probiotics, Shewanella colwelliana WA64 and Shewanella olleyana WA65, on the innate immunity of abalone (Haliotis discus hannai Ino), and survival of juvenile abalone challenged with Vibrio harveyi have been studied. Two groups of abalone were fed with three different diets: one control, and two diets supplemented with 10(9) cell g(-1) of probiotic WA64 (WA64 diet) and WA65 (WA65 diet) for up to four weeks. Results showed that abalone fed diets containing S.
