Scalable Preparation of Superdurable, Self-Healing, and Biocompatible Superhydrophobic Poly(ethylene terephthalate) Fabrics.

The chemical inertness of poly(ethylene terephthalate) (PET) fabrics poses challenges in achieving superhydrophobic coatings with durable adhesion on their surfaces. Conventional surface modification methods such as alkali etching and plasma etching typically compromise the favorable mechanical properties of PET. In this study, polydopamine (PDA) was utilized to functionalize the PET fabric nondestructively by creating robust and reactive hydroxyl and amine groups on its surface, which were subsequently used as a binder of superhydrophobic modifiers such as fluorine-free octadecyltrichlorosilane (OTS).

ZIF-67 nanocubes assembly-derived CoTe nanoparticles encapsulated hierarchical carbon nanofibers enables efficient lithium storage.

Tellurides are promising anode materials for lithium-ion batteries (LIBs) because of their high electronic conductivity and energy density.

Catalytic hydrogenolysis of larix bark proanthocyanidins in ionic liquids produces UV blockers with potential for use in cosmetics.

The bark of larix, a major tree species in the coniferous forests of China's Greater Khingan Mountains, is typically treated as waste. The bark is, however, rich in flavonoids, known as proanthocyanidins, although their high degree of polymerization and high molecular weight reduce their biological activity and potential applications. Ionic liquids, a new type of "green solvent", characterized by low vapor pressure and good stability, have been developed and used as new solvents for naturally occurring macromolecules.

Comparison of long-term energy efficiency and microbial community dynamics of different reactors in response to increased loadings of water hyacinth juice.

Water hyacinth is considered to be among the worst invasive weed species globally, causing detrimental environmental and social problems worldwide. It rapidly grows, and therefore has significant potential as a resource. Due to its high moisture content (approximately 95%), the by-product obtained by dehydrating water hyacinth yields a considerable amount of water hyacinth juice (WHJ).

In this study, the fatigue effect was observed for indigenous anaerobic sludge (IAS) of anaerobic digestion system treating swine wastewater. On the contrary, the enhancement effect was demonstrated for exogenous granular sludge (EGS) originated from the internal circulation reactor treating pulping wastewater.

Novel start-up process for the efficient degradation of high COD wastewater with up-flow anaerobic sludge blanket technology and a modified internal circulation reactor.

To avoid wastage of water resources and operating cost increases caused by the traditional start-up process of large amounts of dilution influent chemical oxygen demand (COD), a novel start-up process (NSP) was developed and verified with water hyacinth juice (WHJ) on an up-flow anaerobic sludge blanket (UASB) and modified internal circulation (MIC) reactor.

Fermentative hydrogen production can be improved by electrolysis and electrochemically active microorganisms which are capable of using an electrode as an electron acceptor for the oxidation of organic matter, in particular, volatile acids produced after fermentation. Firstly volatile acids can be completely converted into CO2, electrons and protons on the surface of anode. Then the electrons flow to cathode through anode and wires, and at the same time the protons move to cathode through cation membrane between anode chamber and cathode chamber.

Removal of phosphate from polluted water by lanthanum doped vesuvianite.

The adsorption capacities of vesuvianite and lanthanum doped vesuvianite were studied. The effects of different mass ratios of La/vesuvianite at different contact times, pHs, and temperatures on adsorption capacity were also studied. It was found that lanthanum doped vesuvianite exhibited higher adsorption capacity than undoped one due to the reaction of bounded lanthanum with phosphate.
