Article Synopsis
  • * The study identified two stages of fouling behavior: an initial sharp decrease in performance followed by a stable phase, with bound-extracellular polymeric substances (bEPS) leading to the greatest flux decline.
  • * Chemical analyses indicated that the composition of algal foulants—particularly the ratio of carbohydrates to proteins—significantly affects fouling, with soluble-extracellular polymeric substances (sEPS) playing a larger role in fouling for S.

Self-powered photodetectors have attracted widespread attention due to their low power consumption which can be driven by the built-in electric field instead of external power, but it is very difficult to achieve high responsivity and fast response speed concurrently. Here, a self-powered photodetector with light-induced electric field enhancement based on a 2D InSe/WSe /SnS van der Waals heterojunction is designed. The light-induced electric field derived from the photo-generated electrons of SnS accumulated at the SnS /WSe interface produces an additional negative gate voltage applied to the WSe layer, which enhances the built-in electric field in the InSe/WSe /SnS heterojunction.

In desert habitats, sand burial is an important factor affecting germination of plant seeds and seedling growth. Xanthium spinosum has strong adaptability in arid desert areas, and is a common malignant invasive plant in Xinjiang, China. The effects of different sand burial depths on seed germination, seedling emergence, growth and biomass allocation were studied to provide a scientific basis for further control of X.

Background: Lidocaine is a commonly used local anesthetic, and low-dose lidocaine has neuroprotective effects on cerebral ischemia/reperfusion (CI/R) injury; the mechanism for this, however, is still unclear. The aim of this study was to investigate the role and the possible mechanisms of lidocaine on CI/R injury in rats.

Methods: We constructed a rat (male Sprague-Dawley rats, 6-8 weeks old) model of CI/R injury induced by middle cerebral artery occlusion (MCAO).

Atractylodin is one of the main constituents in the rhizomes of Thunb., being capable of treating cancer cachexia-anorexia and age-related diseases as an agonist of growth hormone secretagogue receptor (GHSR). GHSR was herein expressed in human gastric smooth muscle cells (HGSMCs) and activated by ghrelin receptor agonist L-692,585.

Three porous supramolecular isomers (IZE-1, IZE-2, and IZE-3) with the same framework component [Zn(2)(EBTC)(H(2)O)(2)] (EBTC = 1,1'-ethynebenzene-3,3',5,5'-tetracarboxylate) were successfully constructed by finely tuning the reaction condition. Although both IZE-1 and IZE-2 are constructed from the linear EBTC subunits and one kind of regular [Zn(2)(CO(2))(4)] paddlewheels, their frameworks exhibit two different (3,4)-c net of fof (sqc1575) and sqc1572, respectively, resulting in cavities with different size and shape. However, as for isomer IZE-3, the EBTC ligands are bent and one-half of the [Zn(2)(CO(2))(4)] paddlewheels are distorted, leading to a novel (3,4,4)-c hyx net with point symbol (6.

The polymeric title compound, {[Co(C(15)H(9)NO(4)S)(H(2)O)(3)]·H(2)O}(n), consists of chains along [001] made up from Co(2+) ions bridged by 10-methyl-phenothia-zine-3,7-dicarboxyl-ate anions. The Co(2+) ion, coordinated by three O atoms from two different carboxyl-ate groups and three water mol-ecules, displays a distorted octa-hedral environment. In the crystal, π-π inter-chain inter-actions, with centroid-centroid distances of 3.

Two donor-acceptor molecules with different pi-electron conjugative units, 1-((10-methyl-10H-phenothiazin-3-yl)ethynyl)anthracene-9,10-dione (AqMp) and 1,1'-(10-methyl-10H-phenothiazine-3,7-diyl)bis(ethyne-2,1-diyl)dianthracene-9,10-dione (Aq2Mp), have been synthesized and investigated for their photochemical and electrochemical properties. Density functional theory (DFT) calculations provide insights into their molecular geometry, electronic structures, and properties. These studies satisfactorily explain the electrochemistry of the two compounds and indicate that larger conjugative effect leads to smaller HOMO-LUMO gap (Eg) in Aq2Mp.
