Covalent functionalization of reduced graphene oxide (rGO) was prepared by conjugated polymers with different monomers, using nucleophilic addition reaction between rGO and nitrogen anions. Three conjugated polymers containing tetraphenylethylene, carbazole and phenyl groups were used, due to the π-π interaction and "polymer wrapping" effect, the dispersion stability of rGO was improved. Even the reacting site in polymers were same to each other, there were great differences in the reactivity of the polymers, the dispersion stability of the resultant composites, and also the OL performances of the resultant composites...

In this study, we report a novel, one-step synthesis method to fabricate multi-layer graphene (MLG)-wrapped copper nanoparticles (CuNPs) directly on various substrates (e.g., polyimide film (PI), carbon cloth (CC)) or Si wafer (Si)). The electrical resistivities of the pristine MLG-CuNPs/PI and MLG-CuNPs/Si were measured 1.7 × 10(-6) and 1.4 × 10(-6) Ω·m, respectively, of which both values are ~100-fold lower than earlier reports. The MLG shell could remarkably prevent the Cu nanocore from serious damages after MLG-CuNPs being exposed to various harsh conditions...

PURPOSE: To improve the graph model of our previous work GOOSE for fat-water decomposition with higher computational efficiency and quantitative accuracy. METHODS: A modification of the GOOSE fat water decomposition algorithm is introduced while the global convergence guarantees of GOOSE are still inherited to minimize fat-water swaps and phase wraps. In this paper, two non-equidistant graph optimization frameworks are proposed as a single-step framework termed as rapid GOOSE (R-GOOSE), and a multi-step framework termed as multi-scale R-GOOSE (mR-GOOSE)...

We demonstrated a flexible transparent and free-standing Si nanowire paper (SiNWP) as a surface enhanced Raman scattering (SERS) platform for in situ chemical sensing on warping surfaces with high sensitivity. The SERS activity has originated from the three-dimension interconnected nanowire network structure and electromagnetic coupling between closely separated nanowires in the SiNWP. In addition, the SERS activity can be highly improved by functionalizing the SiNWP with plasmonic Au nanoparticles. The hybrid substrate not only showed excellent reproducibility and stability of the SERS signal, but also maintained the flexibility and transparency of the pristine SiNWP...

Antimony represents a class of unique functional materials in sodium-ion batteries with high theoretical capacity (660 mAh g-1). The utilization of carbonaceous materials as buffer layer has been considered as an effective approach to alleviate rapid capacity fading. Herein, the antimony/nitrogen-doping porous carbon (Sb/NPC) composite with polyaniline nanosheets as carbon source has been successfully achieved. And, our strategy involves three processes-tunable organic polyreaction, thermal annealing process and cost-effective reduction reaction...

Small conjugated carbonyl compounds are intriguing candidates of organic electrode materials because of their abundance, high theoretical capacity and adjustable molecular structure. However, their dissolution in aprotic electrolytes and poor conductivity eclipse them in terms of practical capacity, cycle life and rate capability. Herein, we report a foldable and binder-free nanocomposite electrode consisting of 2-aminoanthraquinone (AAQ) nanowires wrapping within three-dimensional (3D) graphene framework, which is prepared through antisolvent crystallization followed by a facile chemical reduction and self-assembly process...

The large volume variations of tin-based oxides hinder their extensive applications in the field of lithium ion batteries (LIBs). In this study, structure design, hybrid fabrication and carbon coating approaches have been simultaneously adopted to relieve these weaknesses. Therefore, uniform mesoporous NiO/SnO2@rGO, Ni-Sn oxide@rGO and SnO2@rGO nanosphere composites have been selectively fabricated. Among them, the obtained NiO/SnO2@rGO composite exhibits high capacity 800 mAh g-1 at 1000 mA g-1 after 400 cycles...

As tumor microenvironment becoming more and more important in tumor study, the acid pH around or in solid tumors drew lots of attentions. And the progress of drug delivery systems made the responsive-release possible. This time, we fabricated a new-type composite electrospun poly (L-lactide) (PLLA) fibrous scaffolds, that blent with the mesoporous silica particles (MSNs). Further more, we used sodium bicarbonate (SB) as acid sensitive agent which was wrapped inside the MSNs. And doxorubicin (DOX) was also wrapped into MSNs in order to achieve a sustained release to inhibit tumors in mice, which mimicked the remnant breast cancer with surgery...

The repair of large tracheal segmental defects remains an unsolved problem. The goal of this study is to apply tissue engineering principles for the fabrication of large segmental trachea replacements. Engineered tracheal replacements composed of autologous cells ("neotracheas") were tested in a New Zealand White rabbit model. Neotracheas were formed in the rabbit neck by wrapping a silicone tube with consecutive layers of skin epithelium, platysma muscle and an engineered cartilage sheet, and allowing the construct to mature for 8-12 weeks...

Ingredients found in the nail cosmetic industry, including but not limited to methacrylate and acrylate monomers, formaldehyde, and toluene sulfonamide-formaldehyde resin, can incite allergic contact dermatitis. An eczematous outbreak presents on areas surrounding the nail plate and may spread through contact transfer of the allergen, commonly to the face and neck. Even components that were originally deemed nonsensitizing, such as the ubiquitous cyanoacrylate adhesive family, have been found to be allergenic...

With the flourishing development of (CH3NH3)PbI3, three-dimensional (3D) organic-inorganic perovskites with unique structure-property flexibility have become a worldwide focus. However, they still face great challenges in effec-tively inducing ferroelectricity. Despite the typical 3D perovskite structure and the ability of dabco to trigger phase transition, unfortunately [H2dabco]RbCl3 (dabco = 1,4-diazabicyclo[2.2.2]octane) adopts a nonpolar crystal structure without ferroelectricity. Within larger RbI3 framework, we assemble N-methyl-dabco gained by reducing the molecular symmetry of dabco into a new 3D organic-inorganic perovskite...

Crisis theory suggests that in addition to presenting a threat to mental well-being, crises are also opportunities where successful interventions can lead to successful outcomes. UK mental health crisis teams aim to reduce hospital admission by treating people at home and by building resilience and supporting learning from crisis, yet data on repeat crisis episodes suggest this could be improved. This qualitative study sought to explore the Wellness Recovery Action Plan (WRAP) as a means of supporting resilience-building and maximising the opportunity potential of crisis...

The human muscleblind-like proteins (MBNL) regulate tissue-specific splicing by targeting cardiac troponin T and other pre-mRNAs; aberrant targeting of CUG and CCUG repeat expansions frequently accompanies the neuromuscular disease myotonic dystrophy. We show, using biolayer interferometry (Octet), and NMR spectroscopy, that the zinc finger domains of MBNL isoform 1 (MBNL1) are necessary and sufficient for binding CGCU sequences within the pre-mRNA of human cardiac troponin T (hcTnT). Protein constructs containing zinc fingers 1 and 2 (zf12) and zinc fingers 3 and 4 (zf34) of MBNL1 each fold into a compact globular tandem zinc finger structure that participates in RNA binding...

Researchers have widely agreed that the broad spectrum antibacterial activity of silver nanoparticles (AgNPs) can be predominantly ascribed to the action of Ag+. This study marks the first report detailing the rapid and highly efficient synergistic bacteria killing of AgNPs, which is achieved by inspiring AgNPs' strong photocatalytic capability to rapidly produce radical oxygen species using 660 nm visible light together with the innate antimicrobial ability of Ag+. These AgNPs were uniformly distributed into well-defined graphene oxide (GO) nanosheets through an in-situ reduction of Ag+ and subsequently wrapped with a thin layer of typeⅠcollagen...

A polymeric column that contains a multiwalled carbon nanotubes-β-cyclodextrin composite was developed. The composite was wrapped into the poly(butyl methacrylate-ethylene dimethacrylate) monolith column (0.76 mm I.D. and 10 cm in length). The column was then applied for the online solid-phase microextraction of psoralen and isopsoralen from Fructus Psoraleae. Following microextraction, the coumarins were quantified by high-performance liquid chromatography with C18 separation column and UV detection. The effects of sample flow rate, sample volume and pH value were optimized...

Thermally insulating materials, made from earth-abundant and sustainable resources, are highly desirable in the sustainable construction of energy efficient buildings. Cellulose from wood has long been recognized for these characteristics. However, cellulose can be a flammability hazard, and for construction this has been addressed via chemical treatment such as that with halogen and/or phosphorus, which leads to further environmental concerns. Fortunately, the structure of cellulose lends itself well to chemical modification, giving great potential to explore interaction with other compounds...
