“…In terms of the controllable synthesis of vanadium oxide cathode for SIBs, nanoscience engineering makes it possible to control the morphology and composition of cathode to effectively enhance the electrochemical performance. Recently, numerous reported method can be applied to obtain diverse nanostructures (i.e., hollow structure, [33] hierarchical heterostructures, [18,19,60] complex 3D architectures, [62] etc.) with peculiar electrochemical properties, interlayer spaces and morphologies.…”

“…The concept of enhancing Na storage performance via nanostructuring has been recognized in numerous research works. [16][17][18][19][20] These novel nanostructures are proved to possess robust structural integrity and stability, faster electrochemical reaction rate, and enhanced reaction reversibility. In this perspective, we provide a brief review of recent advances in several typical vanadium oxides, and discussions on the engineering of unique nanostructures and its beneficial effects on enhancing the SIBs performance.…”

Sodium-ion batteries (SIBs) have received intensive attentions owing to the abundant and inexpensive sodium (Na) resource. Layered vanadium oxides are featured with various valence states and corresponding compounds, and through multi-electron reaction they are capable to deliver high Na storage capacity. The rational construction of unique structures is verified to improve their Na storage properties. This perspective provides an overview of recent advances in layered vanadium oxide for SIBs, with a particular focus on construction of novel nanostructures, and mechanism studies via in situ characterization. Finally, we predict possible breakthroughs and future trends that lie ahead for high-performance layered vanadium oxides SIBs cathode.

“…In recently published reports, various kinds of carbon coatings are applied as a conducting network to improve electron transport and this may be in the form of carbon nanotubes/nanofibers/nanorods and/or graphene . Very recently, 3D interconnected conducting network strategies, which utilize a combination of different carbons have been investigated but only one publication on Na 3 V 2 (PO 4 ) 3 to date has explored the possibilities of a free‐standing electrode design …”

Sericin-wrapped mesoporous silica nanoparticles (SMSNs) with pH and protease dual responsiveness are successfully fabricated as a lysosome-targeting drug delivery system by Guobin Wang, Lin Wang, Zheng Wang, and co-workers in article number 1602567. Such a dual responsive system offers a rapid doxorubicin release in lysosomes, which bypasses the membrane pump mediated drug efflux, thereby achieving the reversal of drug resistance. Mercuric Contamination An ultrasensitive surface-enhanced Raman scattering (SERS) substrate with large area uniform subnanometer "hot spots" is used to detect mercuric ions in water and sandy soil, by Hongbing Deng, Fubing Wang, Xiangheng Xiao, and co-workers in article number 1603347. The detection limit is as low as 8.3 × 10 −9 m. The uniformity of the SERS substrate is proved by Raman mapping, and the physical mechanism of SERS enhancements is supported by the finite difference time domain method. Drug Delivery In article number 1603109, Jiashu Sun, Haijun Yu, Xingyu Jiang, and co-workers utilize microfluidic chips to generate rigid pH-sensitive micellar nanocomplex (RPN) with tunable rigidity and acid-switchable surface charge for overcoming cancer drug resistance. The functionalization of RPN is realized through the incorporation of rigid PLGA core into pH-sensitive micelle. The RPN significantly enhances therapeutic efficacy against MCF-7/ADR xenograft tumor in mice, without the All inorganic halide perovskite nano-systems are expected to be promising materials for next generation lighting, display , and many other applications. Within two years, lots of interesting results have been observed. The synthesis and progresses on optoelectronic devices and optical applications, such as LEDs, photo-detectors, solar cells, and lasing, are summarized. Future directions, challenges and possible applications are also put forward. reviews Printing Functional 3D Microdevices by Laser-Induced Forward Transfer Slender, out-of-plane metal micro devices are made in a new spatial domain, by using laser-induced forward transfer (LIFT) of metals. Here, a thermocouple with a thickness of 10 µm and a height of 250 µm, consisting of platinum and gold pillars is demonstrated. Multi-material LIFT enables manufacturing in the micrometer to millimeter range, i.e., between lithography and other 3D printing technologies. communications Zeolitic imidazolate framework-8 (ZIF-8)-derived N-doped graphene analogous poly-hedrons (ZNGs) obtained via the direct carbonation of ZIF-8 are applied to photocat-alytic hydrogen evolution for the first time. The contents of different types of nitrogen atoms in ZNGs can be fine-tuned via the calcination temperature, which significantly influences the hydrogen evolution rate of the ZNGs.

“…The main limitation with this material is its poor electrical conductivity (≈10 −9 S cm −1 ) due to the slightly distorted arrangement of VO 6 octahedra, thus resulting in poor cycling performance and rate capability, which limits its practical performance and further commercialization . Researchers have tried various approaches to overcome this problem, which include nanostructuring, coating with a thin film of carbon and/or some other conducting material, doping with secondary ions, etc . From a commercial and large‐scale production aspect, however, carbon coating is doubtless an effective approach to enhance the electrochemical performance .…”

Even though significant improvements have been made in sodium ion batteries, battery management mandates that all batteries in a pack are kept at an acceptable level of more than 80% capacity retention after a long cycle when it is tested for emergencies. Based on these realistic facts, the present study profitably exploits in situ grown reduced graphene oxide on 3D Na3V2 (PO4)3 matrices exhibiting a high rate performance and a specific discharge capacity of 117 mAh g-1. Unlike the earlier literature reports, it is demonstrated that the fabricated electrode shows >85% capacity retention after 6000 cycles at 10 C, the longest cycle life reported till date. The work also reasons in-depth the outstanding sodiation/desodiation capabilities to the low hysteresis voltage and how these electrodes can be used for deep discharges by extending the potential window to 1.3-3.8 V (vs Na/Na+) resulting in a noteworthy specific capacity of ≈165.4 mAh g-1 at 1 C.
