Confinement and antenna effect for ultrasmall Y2O3:Eu3+ nanocrystals supported by MOF with enhanced near-UV light absorption thereby enhanced luminescence and excellently multifunctional applications

Hongyi Xu1, Wenjing Yu1, Kai Pan1, Guofeng Wang1 (✉), and Peifen Zhu2 (✉)

A novel host-guest luminous system composed of Y2O3:Eu3+/ (Eu/Y-BTC) is affected by the synergy of quantum confinement, spatial confinement and antenna effect, and the absorption of nearultraviolet light increases. The absorption and emission of light are effectively enhanced, and it has shown important application value in the research field of white light-emitting diodes (LEDs) and dye-sensitized solar cells (DSSCs).

Spider web-like carbonized bacterial cellulose/MoSe2 nanocomposite with enhanced microwave attenuation performance and tunable absorption bands

Zhengjian Xu1,2, Man He1 (✉), Yuming Zhou1 (✉), Shuangxi Nie2, Yongjuan Wang1, Yao Huo1, Yifan Kang1, Ruili Wang1, Ran Xu1, Hao Peng1, and Xi Chen1

The spider web-like carbonized bacterial cellulose/MoSe2 composite was fabricated by a facile process and economical raw materials, which have enhanced microwave attenuation performance and tunable absorption bands. The composite effectively solves the problems of impedance mismatch caused by pure bacterial cellulose and high filler content caused by pure MoSe2, offsetting respective shortcomings.

Unravelling a solution-based formation of single-crystalline kinked wurtzite nanowires: The case of MnSe

Xinyi Yang1, Bo Zhou1, Chuang Liu1, Yongming Sui1, Guanjun Xiao1, Yingjin Wei2, Xin Wang3, and Bo Zou1 (*)

A rational strategy for nonpolar axial-oriented growth and switching was developed to sculpt single-crystalline kinked wurtzite MnSe nanowires in a facile solution-based procedure. The ability to continuously switch the nonpolar axial-growth orientation allowed us to craft the multiply kinking landscape.

Tunable oxygen vacancy concentration in vanadium oxide as mass-produced cathode for aqueous zinc-ion batteries

Yehong Du1, Xinyu Wang1,2 (✉), and Juncai Sun1 (✉)

A simple spontaneous polymerization strategy was developed to fabricate mass-produced VöVP cathodes with a tunable oxygen vacancy (Vö) concentration in vanadium oxide. The electrochemical performance of VöVP cathodes can directly be controllable by the concentration of Vö.

Macrophage-targeted single walled carbon nanotubes stimulate phagocytosis via pH-dependent drug release

Yapei Zhang1,2,§, Jianqin Ye3,§, Niloufar Hosseini-Nassab6, Alyssa Flores3, Irina Kalashnikova1,2, Sesha Lakshmi Paluri1,2, Mozhgan Lotfi3, Nicholas J. Leeper3,4,5,¶ (✉), and Bryan Ronain Smith1,2,¶ (✉)

Apoptotic cellular debris at the core of atherosclerotic plaques may produce inflammation and instability leading to heart attacks. We show here that single-walled carbon nanotubes (SWNTs), which display exquisite selectivity for inflammatory monocytes/ macrophages, can deliver a potent small molecule intracellular inhibitor highly selective for SHP1 via pH-dependent release to re-stimulate macrophage uptake of apoptotic cellular debris.
