Multi-redox phenazine/non-oxidized graphene/cellulose nano hybrids as ultrathick cathodes for high-energy organic batteries

Youngjin Ham¹, Vitalii Ri², Jin Kim¹, Yeoheung Yoon³, Jinho Lee¹, Kisuk Kang⁴, Ki-Seok An³ (✉), Chunjoong Kim² (✉), and Seokwoo Jeon¹ (✉)

An ultrathick (≈ 1 mm) organic cathode is developed by utilizing the synergetic effect of the non-covalent functionalized graphene flakes and robust cellulose nanofiber-intermingled architecture. Due to the well-developed ion/electron pathways throughout the entire cathode thickness, the multi-redox phenazine-based organic rechargeable batteries exhibit high energy of 9.4 mWh·cm⁻² (= 864 Wh·kg⁻¹), as well as enhanced cycling stability.

Long-term exposure to titanium dioxide nanoparticles promotes diet-induced obesity through exacerbating intestinal mucus layer damage and microbiota dysbiosis

Xiaoqiang Zhu^1,§, Lijun Zhao^1,§, Zhi Liu², Qibing Zhou¹, Yanhong Zhu¹ (✉), Yuliang Zhao³ (✉), and Xiangliang Yang¹ (✉)

Long-term oral exposure to titanium dioxide nanoparticles (TiO₂- NPs) increases gut permeability through mucus layer damage and induces microbiota dysbiosis, which together result in low-grade systemic inflammation, thus aggravating high fat diet (HFD)-induced obesity.

Is tumor cell specificity distinct from tumor selectivity in vivo? A quantitative NIR molecular imaging analysis of nanoliposome targeting

Girgis Obaid^1,2,†,§, Kimberley Samkoe^3,§, Kenneth Tichauer⁴, Shazia Bano¹, Yeonjae Park³, Zachary Silber¹, Sassan Hodge³, Susan Callaghan¹, Mina Guirguis², Srivalleesha Mallidi^1,‡, Brian Pogue³, and Tayyaba Hasan^1,5 (✉)

Biomolecular interactions of targeted nanoliposomes (tNLs) with solid tumor receptors in vivo are elusive. Here, for the first time, tNLs specific for epidermal growth factor receptor (EGFR) are used with near-infrared (NIR) molecular imaging for non-invasive quantitation of their in vivo molecular specificity towards tumor EGFR. We also show that tumor specificity is independent of tumor selective delivery. The purpose of targeting is thus emphasized and tNL development is encouraged, given that the principal goal for targeting is in vivo molecular specificity.

Self-assembly of semiconductor nanoparticles toward emergent behaviors on fluorescence

Xiao Li^1,2, Zhili Lu³, and Tie Wang^1,2,4 (✉)

In this review, we highlight the recent advances in the fluorescence of individual semiconductor nanoparticles, inter-nanoparticles coupling and thus emergent fluorescence behaviors of assemblies. The coupling is the necessary pathway for assemblies beyond individual building blocks to produce emergent fluorescence properties.

A two-dimensional lateral transition metal disulfide-oxide-disulfide heterostructure with a configuration of an ultrathin Nb₂O₅ channel and two metallic NbS₂ electrodes is fabricated by a simple lithographyfree, laser-patterning technique. The heterostructure can be used as an ultrasensitive two-terminal sensor based on the modulation of Nb₂O₅ surface conduction through the naturally adsorbed water molecules.

TiO₂ Nanocrystals Grown on Graphene as Advanced Photocatalytic Hybrid Materials

Yongye Liang^§, Hailiang Wang^§, Hernan Sanchez Casalongue, Zhuo Chen, and Hongjie Dai ()

A graphene/TiO₂ nanocrystals hybrid has been prepared by directly growing TiO₂ nanocrystals on graphene oxide (GO) sheets by a two-step method, in which TiO₂ was first coated on GO sheets by hydrolysis and subsequently crystallized into anatase nanocrystals by hydrothermal treatment. The graphene/TiO₂ nanocrystals hybrid shows superior photocatalytic activity to other TiO₂ materials in the degradation of rhodamine B, with an impressive three-fold photocatalytic enhancement over P25
