Low-strain and ultra-long cycle stability large-diameter soft carbon microsphere potassium ion anode.

Potassium-ion batteries (PIBs) with high potassium abundance, low redox potential of K/K and similar energy storage mechanism to lithium-ion batteries are potential candidates for large-scale energy storage in the future. However, due to the large size of K (1.38 Å), PIBs exhibit poor kinetics in existing commercial graphite anode materials system.

A multi-functional zwitterionic hydrogel with unique micro-structure, high elasticity and low modulus.

Owing to their tissue-like softness and low modulus, hydrogels minimize the mechanical mismatch with biological tissues and have received wide attention as biomaterials. However, the development of soft hydrogels is often limited by their brittleness. Here, an ultra-soft and tough hydrogel based on zwitterionic poly(sulfobetaine methacrylate) (PSBMA) was designed and successfully prepared.

Porous structured cotton-based ACF for the adsorption of benzen.

Fibrous activated carbon has attracted emerging research interests due to its remarkable adsorption performance for volatile organic compounds (VOCs). Though this adsorption behavior for VOCs is closely related to the pore structure on the surface of activated carbon fiber (ACF), few researchers paid attentions to the influence of textural properties of this adsorption process. Especially, cotton-based activated carbon fiber (CACF) for adsorbing benzene pollutant is rarely reported.

Villi-like poly(acrylic acid) based hydrogel adsorbent with fast and highly efficient methylene blue removing ability.

Organic dye-containing wastewater has become an increasingly serious environmental problem due to the rapid development of the printing and dyeing industry. Hydrogel is a promising adsorbent for organic dyes because of its unique three-dimension network structure and versatile functional groups. Though many efforts have been made in hydrogel adsorbents recently, there is still a critical challenge to fabricate hydrogel adsorbent with high adsorption capacity and high efficiency at the same time.

Preparation and Visible-Light Driven Photocatalytic Properties of CuS/Reduced Graphene Oxide Composites.

The CuS/RGO composites were prepared using a facile one-step solvothermal method. The asobtained samples were characterized by X-ray diffraction (XRD), Raman spectra, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), Brunner-Emmet-Teller (BET) measurements and UV-Vis spectrophotometry. The results showed that the CuS particles were uniformly dispersed on the surface of RGO and electronic migration effect existed between RGO and CuS.
