Evaluating the Impact of Cellulose Nanocrystals on the Performance of Polycarbonate Thin‐Film Nanocomposite Membranes for Treating Oily Wastewater

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A new type of thin‐film nanocomposite (TFN) membrane was synthesized by incorporating cellulose nanocrystals (CNCs) into a polyvinyl alcohol (PVA) top layer on a polycarbonate (PC) substrate via dip‐coating. The synthesized TFC and TFN membranes (PC/PVA TFC and PC/PVA‐CNC TFN membranes) were evaluated using contact angle measurement, field ...

THE ASSESSMENT OF ANALYTICAL DOUBLE-SHOT PYROLYSIS WITH GAS CHROMATOGRAPH-MASS SPECTROMETRY APPLICATION OPPORTUNITY FOR THE HUMIC MATTER INVESTIGATION IN SITU

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2018
Double-shot pyrolysis with gas chromatography and mass detection (Double-shot GC MS) was conducted for a sample of typical chernozem and humic acids separated from it. The humic acids preparations were pyrolyzed at 500, 600 and 700°C.

Sustainable Graphene Oxide–Intercalated Bentonite Composite for the Effective Removal of Imidacloprid From Water: Adsorption Performance, Isotherm, and Kinetics

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Water is a fundamental necessity for our existence, but its rapid contamination is causing devastating effects on the environment and health of living species worldwide. Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents.

Resource Allocation Trade‐Offs and Rewired Mycorrhizal Networks Underlie the Adaptation of Paphiopedilum purpuratum to Ex Situ Conservation

open access: yesBiological Diversity, EarlyView.
Paphiopedilum purpuratum Mediates Adaptation via a Dual‐Fungal Strategy: Confronting a physiological trade‐off (↑seed set vs. ↓photosynthesis), Paphiopedilum purpuratum restructures its root microbiome. Mycorrhizal fungi stabilize into a resilient core network, whereas non‐mycorrhizal fungi shift to a dynamic beneficial periphery.

Wurtzite‐Chalcopyrite Crystal Polymorphism in CuGaS2 Nanoparticles Dictates the Localized Surface Plasmon Resonance

open access: yesChemistry – A European Journal, EarlyView.
Crystal phase‐ and size‐selective synthesis of chalcopyrite and wurtzite‐type CuGaS2 NPs was successfully achieved. They exhibited clear LSPR in the NIR region. The extinction coefficient of chalcopyrite was three times higher than that of wurtzite due to its greater symmetry and dipole moment. These results will enable precise control of the plasmonic
