      Mengxi Wu, Haoyang Wang, Guoqing Dong, Brian D. Musselman, Charles C. Liu and Yinlong Guo

      Article first published online: 9 DEC 2014 | DOI: 10.1002/cjoc.201400564

      A method for rapid identification and quantification of 15 phthalate plasticizers in beverages was developed. By a combined solid-phase micro-extraction (SPME) and direct analysis in real time mass spectrometry (DART-MS) approach, phthalates at sub-ng·mL−1 levels can be qualitatively and quantitatively analyzed in a short time. The use of ultrahigh-resolving power and the accurate mass measurement capacity naturally provided by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) minimizes the matrix interferences and thus enables the evaluation of phthalates in a complex matrix without extensive sample handlings or preparations. This rapid and easy-to-use SPME-DART-FT-ICR-MS method provided a relatively high-throughput and powerful analytical approach for quick testing and screening phthalates in beverages and water samples to ensure food safety.

      Silver nanowires with high aspect ratio and high purity were prepared via a rapid, simple and cost-effective polyol method. The aspect ratios of the silver nanowires were as high as ca. 1000 (average length 40 µm and some even as long as 80 µm, diameter 50–100 nm) via optimizing the reaction conditions. Transparent electrodes with superior optoelectronic performances (optical transmittance of 90%, sheet resistance of 23.2 Ω/□ and optical transmittance of 87%, sheet resistance of 19.7 Ω/□) comparable to commercial ITO were fabricated via spin coating the resulting silver nanowires onto the glass substrates. The high optoelectronic performances and the all-solution process of the as-prepared transparent electrodes render them rather promising for applications in cost-effective large-area optoelectronic devices.

    1. Recent Advances in Near-Infrared Absorption Nanomaterials as Photoacoustic Contrast Agents for Biomedical Imaging

      Juchen Zhang, Zengying Qiao, Peipei Yang, Jie Pan, Lei Wang and Hao Wang

      Article first published online: 3 NOV 2014 | DOI: 10.1002/cjoc.201400493

      Thumbnail image of graphical abstract

      Photoacoustic imaging (PAI) is an emerging whole-body imaging modality offering high spatial resolution, deep penetration and high contrast in vivo. Signals for PAI are generated from contrast agents, where the pulsed laser-generated optical energy is transferred to acoustic emissions and detected by an ultrasound transducer. A great deal of research over the past ten years has shown that near-infrared absorption nanomaterials such as organic dye-based nanoparticles, semiconducting polymers, carbon-based nanomaterials, metallic nanomaterials and PA-enhanced hybrid nanocomposites are promising PA contrast agents, which can increase imaging resolution, contrast and even depth of detection.

    1. Controllable Fabrication of Various Supramolecular Nanostructures Based on Nonamphiphilic Azobenzene Derivatives and Pillar[6]arene

      Shan Qin, Shuhan Xiong, Yang Han, Xiao-Yu Hu and Leyong Wang

      Article first published online: 8 OCT 2014 | DOI: 10.1002/cjoc.201400508

      Thumbnail image of graphical abstract

      Various novel types of supramolecular nanostructures formed by nonamphiphilic azobenzene derivatives, G1 or G2 have been successful fabricated, where G2 is structurally similar with G1 but an extra phenoxy group is connected with the azobenzene motif. Micellar structures can be obtained from the self-assembly of G1, which further transformed to large-sized spindle structures; while nanorods can be initially formed by G2, which will gradually aggregate to form layered structures with much larger size. Moreover, it is found that upon addition of WP6, which can form inclusion-complex with G1 or G2, separately, the nonamphiphilic G1 and G2 thus converse to supramolecular amphiphiles WP6G1 and WP6G2, respectively. Consequently, both of the above WP6G1 and WP6G2 complexes can further assemble to form supramolecular binary vesicles, which will gradually transform to nanotubes (WP6G1) or well-ordered nanosheets (WP6G2).
