The fabrication of graphitic carbon nitride with 3-dimensionally extended highly ordered pore arrays is described, and the N-rich porous was utilized for first time as a support Pt50–Ru50 alloy catalyst to study effect on anodic performance in direct methanol fuel cells; it displays promising results cell.
Hydrolysis of In(O-iPr)3 by 10 molar excess water at 90 degrees C in a surfactant/solvent mixture oleylamine/oleic acid/trioctylamine provides very small nanoparticles (<5 nm diameter) In(O)(OH). Subsequent situ thermolysis the formed In(O)(OH) 350 and ambient pressure produces monodisperse h-In2O3 nanocubes, which can form an extended two-dimensional array on flat surface. The size In2O3 nanocubes (8, 10, 12 nm) could be easily controlled simple change amounts employed surfactants. nanocube...
Image enhancement: Core–shell [email protected]3O4 urchin-shaped nanoparticles can be synthesized by means of an anisotropic etching process and used as a pH-activatable T1 contrast agent for magnetic resonance imaging. The manganese ions released from the MnO phase in low-pH sites within tumor cells lead to enhanced image entire mass. Detailed facts importance specialist readers are published "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made...
Hierarchical nanostructured hollow core/mesopore shell carbon (HN-HCMSC) represents an innovative concept in electrochemical hydrogen storage. This work deals with physical characteristics and storage behavior of the HN-HCMSCs, produced by a replica technique using solid (SCMS) silica as template. HN-HCMSCs various core sizes and/or thicknesses have been fabricated through independent control SCMS templates. The superb structural including large specific surface area micropore volume,...
Environmental damage from serious nuclear accidents should be urgently restored, which needs the removal of radioactive species. Radioactive iodine isotopes are particularly problematic for human health because they released in large amounts and retain radioactivity a substantial time. Herein, we prepare platinum-coated iron nanoparticles (Fe@Pt) as highly selective reusable adsorbent species, i.e., iodide (I-), (I2), methyl (CH3I). Fe@Pt selectively separates species seawater groundwater...
Hierarchical nanostructured spherical carbon with hollow macroporous core in combination mesoporous shell has been explored to support Pt cathode catalyst high metal loading proton exchange membrane fuel cell (PEMFC). The core–mesoporous (HCMSC) unique structural characteristics such as large specific surface area and volume, ensuring uniform dispersion of the supported (60 wt%) nanoparticles small particle size, well-developed three-dimensionally interconnected hierarchical porosity...
Abstract Background Monitoring microbial communities especially focused on pathogens in newly developed wastewater treatment systems is recommended for public health. Thus, we investigated the community shift a pilot-scale microalgal system piggery wastewater. Results Microalgae showed reasonable removal efficiencies COD and ammonia, resulting higher transparency of final effluent. Metagenome diversity analyses that heterotrophic cultivation barely changed bacterial community; however,...
Abstract Background The gut microbiome is a critical modulator of host immunity and linked to the immune response respiratory viral infections. However, few studies have gone beyond describing broad compositional alterations in severe COVID-19, defined as acute or other organ failure. Methods We profiled 127 hospitalized patients with COVID-19 ( n = 79 48 moderate) who collectively provided 241 stool samples from April 2020 May 2021 identify links between severity microbial taxa, their...
Abstract Background Methane is an abundant and low-cost carbon source with great potential for conversion into value-added chemicals. Methanotrophs, microorganisms that utilize methane as their sole energy source, present a promising platform biotechnological applications. This study aimed to engineer Methylomonas sp. DH-1 enhance D-LA production through metabolic pathway optimization during large-scale cultivation. Results In this study, we regulated the expression of D-lactate...
Microalgae accumulate abundant lipids and are a promising source for biodiesel. However, carbohydrates account 40% of microalgal biomass, an important consideration when using them the economically feasible production In this study, different acid hydrolysis post-treatment processing Chlorella sp.
