    Low-voltage p-channel and n-channel organic transistors with channel lengths down to 0.5 μm using four small-molecule semiconductors and ultra-thin dielectrics based on two different phosphonic acid monolayers are fabricated on plastic substrates and studied in terms of effective mobility, intrinsic mobility and contact resistance. For the optimum materials combination, flexible complementary circuits have signal delays of 3.1 μs at 5 V

    A novel approach to modulating the chemical state of dopants by engineering the topological features of a glass matrix is presented. The method allows selective stabilization of dopants on a wide range of length scales, from dispersed ions to aggregated clusters to nanoparticles, leading to various intriguing optical phenomena, such as great emission enhancement and ultra-broadband optical amplification.

  4. Immunological Responses Triggered by Photothermal Therapy with Carbon Nanotubes in Combination with Anti-CTLA-4 Therapy to Inhibit Cancer Metastasis

    In this work, it is uncovered that photothermal ablation of primary tumors with single-walled carbon nanotubes is able to trigger significant adaptive immune responses, which are not observed if ­tumors are removed by surgical resection. Such a treatment in combination with anti-CTLA-4 antibody therapy is able to prevent the development of tumor metastasis, which is a major cause of cancer death.

  5. Morphology Genetic Materials Templated from Natural Species

    Morphology genetic materials utilize morphologies gleaned from biological structures into their hierarchical structures. This review shows the strategies by which the structures and functions of natural species can be utilized. Specific functions inherited from both natural microstructures and coupled functional materials are highlighted with regard to various applications, including light-harvesting, surface-enhanced Raman scattering (SERS), and electrodes for supercapacitors and batteries.
