Multi-faceted examination of a deepwater seamount reveals ecological patterns among coral and sponge communities in the equatorial Pacific.

Spatial changes in benthic community structure have been observed across natural gradients in deep-sea ecosystems, but these patterns remain under-sampled on seamounts. Here, we identify the spatial composition and distribution of coral and sponge taxa on four sides of a single central Pacific equatorial "model" seamount within the US EEZ surrounding the Howland and Baker unit of the Pacific Islands Heritage Marine National Monument. This seamount rises from 5,000 + m to mesophotic depths of 196 m, and is influenced by the Equatorial Undercurrent.

As modification strategies are actively developed, the photothermal effect is expected to be a viable way to enhance the PEC water splitting performance. Herein, we demonstrate that the photothermal polyaniline (PANI) layer inserted between CoF cocatalyst and BiVO can enhance the photocurrent density of pure BiVO by 3.50 times.

Keyhole limpet haemocyanins (KLH1 and KLH2) from , are multi-subunit oxygen-carrying metalloproteins of approximately 3900 amino acids, that are widely used as carrier proteins in conjugate vaccines and in immunotherapy. KLHs and their derived conjugate vaccines are poorly characterized by LC-MS/MS due to their very stable supramolecular structures with megadalton molecular mass, and their resistance to efficient digestion with standard protocols. KLH1 and KLH2 proteins were conjugated to the conserved P0 peptide (pP0), derived from the P0 acidic ribosomal protein of sp.

Doping and surface-modification are well-established strategies for the performance enhancement of bismuth vanadate (BiVO) photoanodes in photoelectrochemical (PEC) water splitting devices. Herein, a "double-use" strategy for the development of high-performance BiVO photoanodes for solar water splitting is reported, where a molecular cobalt-phosphotungstate (CoPOM = Na[Co(HO)(PWO)]) is used both as a bulk doping agent as well as a surface-deposited water oxidation cocatalyst. The use of CoPOM for bulk doping of BiVO is shown to enhance the electrical conductivity and improve the charge separation efficiency, resulting in the enhancement of the maximum applied-bias photoconversion efficiency (ABPE) by a factor of ∼18 to 0.

The high salt content and color are regarded as a major challenge to the reuse of industrial wastewater. In the present study, the application of cellulose acetate reverse osmosis (RO) membrane in combination with microfiltration (MF), ultrafiltration (UF), or nanofiltration (NF) process was investigated in the purification of biological and Fenton treated pulp and paper wastewater. In the first step, the effect of pH and inlet pressures on the membrane fouling was investigated.
