Li-ion battery materials: present and future

We report the two-photon absorption induced lasing performance in a single CdS microwire under the excitation of a femtosecond pulse laser with a wavelength of 800 nm. Sharp lasing peaks are centered at 523 nm with an average linewidth of 0.4 nm, indicating a high quality factor of 1300. The lasing emission is highly dependent on the polarization direction of the excitation light and the optimized lasing threshold is estimated to be 3.3 mJ/cm2 as the polarization direction is parallel to the microwire axis. Furthermore, the polarization-dependent lasing effect is confirmed by performing the finite-difference time-domain method.

Two-photon pumped lasing in a single CdS microwire

Single-crystal Ca2Ge7O16 nanowires (∼10 nm in diameter) have been encapsulated within graphene sheets successfully to form a nanocomposite with three-dimensional hierarchical nanostructure by a facile hydrothermal method on a large scale. The as-synthesized Ca2Ge7O16 nanowire/graphene sheet nanocomposite electrode exhibits high specific capacity (ca. 950 mA h g−1 at a current density of 100 mA g−1), good cyclability, and excellent rate capability (ca. 400 mA h g−1 at a current density of 3200 mA g−1). Such superior lithium storage performance, on the one hand, could be assigned to the graphene sheets which act as conductive substrates and elastic networks to disperse and encapsulate the Ca2Ge7O16 nanowires, thereby effectively relieving the volume changes and aggregation of the nanoparticles during Li+ insertion/extraction. And on the other hand, the synergistic effect of the unique nanostructured hybrid, in which the Ca2Ge7O16 nanowires are well-stabilized by graphene sheets with high conductivity and flexibility, is beneficial to enlarge the specific surface area, deliver enough sites to allow dispersion of the Ge nanoparticles, and provide void space to buffer the volume change during discharge/charge cycles. This work provides an effective strategy for the fabrication of functionalized ternary-oxide-based composites as high-performance electrode materials that exhibit good conductivity and eliminate severe electrode pulverization.

Recent advances of flexible sensors for biomedical applications

High-performance thin-film transistors with amorphous indium zinc oxide (IZO) films was deposited by embedding indium oxide nanocrystals (In2O3 NCs) into IZO films based on a sol-gel process. Excellent electrical properties have been demonstrated, including a field-effect mobility value of 32.6 cm2·V-1·s-1 and an on-off ratio of 107 , which were obtained at 1 mol% In2O3 NCs in amorphous IZO films. Our findings demonstrate the feasibility of low-temperature sol-gel-based oxide semiconductor transistors, which is more cost-effective compared with conventional fabrication techniques but with comparable performance.

A facile and selective self-sacrificing template-like conversion process has been developed to produce both high-quality flower-like patterns of radially aligned Bi2(Se,S)3 nanorods and Bi2Se3 nanoflakes at low temperature. In this process, the patterns of radially aligned Bi2S3 nanorod precursors act as both the source materials and template to confine the growth of final products. The possible growth mechanism was discussed based on the experiments. This novel radially aligned morphology may find uses in a variety of areas such as the fabrication of advanced electronic and opto-electronic nanodevices.
