Superhydrophobic sponge-like chitosan/CNTs/silica composite for selective oil absorption and efficient separation of water-in-oil emulsion.

Developing state-of-the-art materials with durability, superhydrophobicity, and superoleophilicity is essential for effective cleanup of oil spills and the treatment of oily wastewater. In this study, a novel superhydrophobic/superoleophilic chitosan-based composite was created by incorporating carbon nanotubes (CNTs) into a chitosan (CS) matrix and depositing superhydrophobic SiO nanoparticles, forming a sponge-like absorbent (SH-SiO@3CNTs/CS) for selective oil absorption and efficient oil/water separation. The optimal CNTs incorporation was comprehensively investigated to enhance the structural stability and mechanical strength of the chitosan/CNTs/silica composite.

Hierarchical Ni-Mn LDHs@CuCO Nanosheet Arrays-Modified Copper Mesh: A Dual-Functional Material for Enhancing Oil/Water Separation and Supercapacitors.

The pursuit of superhydrophilic materials with hierarchical structures has garnered significant attention across diverse application domains. In this study, we have successfully crafted Ni-Mn LDHs@CuCO nanosheet arrays on a copper mesh (CM) through a synergistic process involving chemical oxidation and hydrothermal deposition. Initially, CuCO nanosheets were synthesized on the copper mesh, closely followed by the growth of Ni-Mn LDHs nanosheets, culminating in the establishment of a multi-tiered surface architecture with exceptional superhydrophilicity and remarkable underwater superoleophobicity.

A biomimetic beetle-like membrane with superoleophilic SiO-induced oil coalescence on superhydrophilic CuCO nanosheet arrays for effective O/W emulsion separation.

It is highly attractive to develop highly efficient oil-in-water (O/W) emulsion separation technologies for promoting the oily wastewater treatment. Herein, a novel inversely Stenocara beetle-like hierarchical structure of superhydrophobic SiO nanoparticle-decorated CuCO nanosheet arrays were prepared on copper mesh membrane by bridging polydopamine (PDA) to make a SiO/PDA@CuCO membrane for substantially enhanced separation of O/W emulsions. The superhydrophobic SiO particles on the as-prepared SiO/PDA@CuCO membranes were served as localized active sites to induce coalescence of small-size oil droplets in oil-in-water (O/W) emulsions.

Enhanced catalytic performance of atomically dispersed Pd on Pr-doped CeO nanorod in CO oxidation.

Single-atom noble metal catalysts have been widely studied for catalytic oxidation of CO. Regulating the coordination environment of single metal atom site is an effective strategy to improve the intrinsic catalytic activity of single atom catalyst. In this work, single atom Pd catalyst supported on Pr-doped CeO nanorods was prepared, and the performance and nature of Pr-coordinated atomic Pd site in CO catalytic oxidation are systematically investigated.

Multifunctional Switchable Nanocoated Membranes for Efficient Integrated Purification of Oil/Water Emulsions.

Surfaces with unusual under-liquid dual superlyophobicity are attractive on account of their widespread applications, but their development remains difficult due to thermodynamic contradiction. Additionally, these surfaces may suffer from limited antifouling ability, which has restricted their practical applications. Herein, we report a successful in situ growth of a hybrid zeolitic imidazolate framework-8 and zinc oxide nanorod on a porous poly(vinylidene fluoride) membrane (ZIF-8@ZnO-PPVDF) and its application as a self-cleaning switchable barrier material in rapid filtration for emulsified oily wastewater.

Self-Locked and Self-Cleaning Membranes for Efficient Removal of Insoluble and Soluble Organic Pollutants from Water.

A feasible and efficient membrane for long-term treatment of complex oily wastewater is especially in demand, but its development still remains a challenge because of serious membrane fouling and incomplete/destructive reclamation methods. Herein, an interpenetrating TiO nanorod-decorated membrane with self-locked and self-cleaning properties is rationally fabricated coaxial electrospinning and hydrothermal synthesis. The self-locked membrane shows full reinstatement of the original state and exhibits satisfactory mechanical strength, superhydrophilicity, underwater superoleophobicity, and robust solvent resistance, which endow the membrane with successful separation for 16 types of highly emulsified oil-in-water emulsions (, surfactant-free; anionic, cationic, and nonionic surfactant-stabilized).

Single nucleotide polymorphisms within the Wnt pathway predict the risk of bone metastasis in patients with non-small cell lung cancer.

The Wingless-type (Wnt) signaling pathway plays an important role in the development and progression of cancer. This study aimed to evaluate the relationship between single nucleotide polymorphisms (SNPs) in the Wnt pathway and the risk of bone metastasis in patients with non-small cell lung cancer (NSCLC). We collected 500 blood samples from patients with NSCLC and genotyped eight SNPs from four core genes (WNT2, AXIN1, CTNNB1 and APC) present within the WNT pathway.

CusS-CusR Two-Component System Mediates Tigecycline Resistance in Carbapenem-Resistant .

Background: The increase in carbapenem-resistant (CRKP), especially the emergence of tigecycline-resistant (KP), is a serious public health concern. However, the underlying mechanism of tigecycline resistance is unclear. In this study, we evaluated the role of the CusS-CusR two-component system (TCS), which is associated with copper/silver resistance, in tigecycline resistance in CRKP.
