Fabrication of high tap density LiFe0.6Mn0.4PO4/C microspheres by a double carbon coating–spray drying method for high rate lithium ion batteries

Wen Liu, Ping Gao, Yingying Mi, Jitao Chen, Henghui Zhou and Xinxiang Zhang

Spherical LiFe0.6Mn0.4PO4/C particles with high tap density were successfully synthesized by sintering spherical precursor powders prepared by a modified spray drying method with a double carbon coating process. The obtained secondary spheres were made of carbon-coated nanocrystallines (～100 nm), exhibiting a high tap density of 1.4 g cm−3. The LiFe0.6Mn0.4PO4/C microspheres had a reversible capacity of 160.2 mAh g−1 at 0.1C, and a volume energy density of 801.5 Wh L−1 which is nearly 1.4 times that of their nano-sized counterparts. This spherical material showed remarkable rate capability by maintaining 106.3 mAh g−1 at 20C, as well as excellent cycleablity with 98.9% capacity retention after 100 cycles at 2C and 200 cycles at 5C. The excellent electrochemical performance and processability of the LiFe0.6Mn0.4PO4/C microspheres make them very attractive as cathode materials for use in high rate battery application.

PEGylated reduced graphene oxide as a superior ssRNA delivery system

Liming Zhang,abc Zunliang Wang,b Zhuoxuan Lu,bc He Shen, Jie Huang, Qinghuan Zhao, Min Liu, Nongyue He and Zhijun Zhang

Single stranded ribonucleic acid (ssRNA) acts as a probe, antisense (AS), miRNA analog and inhibitor, and is promising for gene therapy and molecular diagnosis. However, free ssRNA exhibits poor cellular uptake due to its negative charges, and enzyme instability, which have largely limited the practical applications of ssRNA in biomedicine. To address these issues, we have developed a PEGylated reduced graphene oxide (PEG–RGO) nanovector for efficient delivery of ssRNA. We have demonstrated that PEG–RGO exhibits superior ssRNA loading and delivery capability, compared to the widely studied PEGylated graphene oxide (PEG–GO). Computational simulation further suggested that PEG–RGO binds ssRNA much stronger than PEG–GO, consistent with the experimental results. These results will have implications in designing RGO-based biocompatible and efficient ssRNA delivery systems.

Liposomes in biosensors

Qingtao Liu and Ben J. Boyd

Liposomes have been widely applied as carriers of molecules in the fields of nanodevices, drug delivery and gene delivery, as well as a mimic for cell membranes. In the biosensor field, liposomes find special application in signal amplification, due to their excellent carrier properties for encapsulation of signal marker compounds across a wide spectrum of sensing modalities. Additionally, the ability to modify the liposome surface structure to perform recognition functions with a wide range of types of analytes is an important aspect of their use in bioanalysis. This article provides an extensive review of the utility of liposomes in the fields of biosensor and bioanalysis with a focus on these two aspects. The aspects related to the translation of liposomes into commercially viable devices for biosensing are also discussed, and the hurdles to more widespread deployment in point of care systems are addressed.

Photo-induced current amplification in L-histidine modified nanochannels based on a highly charged photoacid in solution

Minghui Zhang, Zheyi Meng, Jin Zhai and Lei Jiang

By UV light irradiation, we can adjust the charge of bistable photoacid molecules reversibly, so that photo-induced current amplification can be obtained, which offers a way to control nanochannels by turning the UV light on and off, alternately.

Free Radicals: Free Radical Reactions in Two Dimensions: A Case Study on Photochlorination of Graphene (Small 8/2013)

Lin Zhou,Lushan Zhou,Mingmei Yang,Di Wu,Lei Liao,Kai Yan,Qin Xie,Zhirong Liu,Hailin Peng,Zhongfan Liu

Graphene is a 2D giant polycyclic aromatic molecule that provides opportunities for studying chemical reactions in two dimensions. H. Peng, Z. Liu, and co-workers have systematically investigated the influence of specific features of 2D molecules, such as their thickness, stacking order, single- and double-side upon graphene's radical reactivity by utilizing a free radical photochlorination as a probe. The result, described on page 1388, can contribute to a deeper understanding of dimensionality effects for the chemistry of 2D graphene.

Sensors: Gas Dielectric Transistor of CuPc Single Crystalline Nanowire for SO2 Detection Down to Sub-ppm Levels at Room Temperature (Adv. Mater. 16/2013)

Talgar Shaymurat,Qingxin Tang,Yanhong Tong,Lin Dong,Yichun Liu

A suspended semiconductor nanowire, which exhibits high sensitivity to SO2 (119% in 0.5 ppm) at room temperature, is reported by Yichun Liu, Qingxin Tang and co-workers on page 2269. This configuration allows the detected gas to make direct contact with the semiconductor/dielectric interface where the charge transport takes place. The back cover shows the adsorption of SO2 at the bottom of the transparent nanowire, allowing high-sensitivity room-temperature SO2 detection.

Organic Electronics: Ultrathin Film Organic Transistors: Precise Control of Semiconductor Thickness via Spin-Coating (Adv. Mater. 10/2013)

Fengjiao Zhang,Chong-an Di,Nikolai Berdunov,Yuanyuan Hu,Yunbin Hu,Xike Gao,Qing Meng,Henning Sirringhaus,Daoben Zhu

Building ultrathin-film organic transistors via spin-coating is a challenge in comparison to the construction of typical thin-film devices. Daoben Zhu and co-workers demonstrate on p. 1401 a simple spin-coating technique to fabricate several kinds of few layer films towards ultrathin film transistors with a variety of applications. Fabrication of ultrathin film organic transistors might be an achieve project in the future.
