This cover was co-designed with Prof. Hong Yang at UIUC for a special issue on Nanoparticles for Catalysis in Accounts of Chemical Research (2013, vol. 46). The special issue is co-edited by Prof. Younan Xia, Prof. Hong Yang and Prof. Charles T. Campbell (University of Washington, Seattle). The last decade has witnessed an explosion in the development of new methods capable of generating metal nanoparticles with controlled compositions, sizes, shapes, and structures in an effort to control the ways in which these nanoparticles can be connected to and even surrounded by support materials like oxides. These nanostructured materials form the basis for many catalysts and electrocatalysts of great importance to future technologies including energy harvesting/conversion/storage, chemical transformation, and environmental protection.

This cover was designed by Dr. Jingwei Xie for an article published in ACS Nano (2010, 4, pp. 5027-5036). It shows the inward migration of dural fibroblasts on a two-dimensional scaffold of electrospun nanofibers with a radial alignment. The scaffolds based on radially aligned, biodegradable nanofibers show great potential as artificial dural substitutes and may be particularly useful as biomedical patches or grafts to induce wound closure and/or tissue regeneration.

This cover was designed by Dr. Jingwei Xie for an article published in ACS Nano (2009, 3, pp. 1151-1159). It shows neurites outgrowing from Dorsal Root Ganglia (DRG) on a two-dimensional mesh of electrospun nanofibers with orthogonal orientations. This kind of research provides valuable information pertaining to the design of nanofiber-based scaffolds for neuroregenerative applications, as well as the effects of topology on neurite outgrowth, growth cone guidance, and axonal regeneration.

This cover was designed by Dr. Yu Zhang (Ph.D. 2013) for an invited essay (Are We Entering the Nano Era? by Y. Xia, pp. 12268-12771) and an invited review article (Engineered Nanoparticles for Drug Delivery in Cancer Therapy by T. Sun, Y. S. Zhang, B. Pang, D. C. Hyun, M. Yang and Y. Xia, pp.12320-12364) published in Angewandte Chemie International Edition (2014, vol. 53), a special issue on nanotechnology, nanomaterials, nanotoxicology and nanomedicine. It shows that nanomaterials is a double-side sword: although the potential of nanotechnology is tremendous, questions remain about the long-term safety of nanomaterials and the risk-benefit characteristics of their usage.  

This inside cover was designed by Professor Hui Zhang (a former visiting scholar in the Xia group from Zhejiang University) for a review article published in Angewandte Chemie International Edition (2012, 51, pp.7656-7673 ) on the design, synthesis, properties, and unique applications of noble-metal nanocrystals with concave surfaces. Due to the presence of high-index facets on the surface, concave nanocrystals are interesting and important as a novel class of catalysts with substantially improved activity.

This backside cover was designed by Dr. Jie Zeng for a communication published in Angewandte Chemie International Edition (2012, 51, pp.2354-2359) on the synthesis of nanocrystals with reduced symmetry by controlling the reaction kinetics. When the injection and thus deposition rate of precursor  was very slow, the atoms could only nucleate on one of the six side faces of a cubic seed. As the injection rate was increased, the nucleation and growth could start to occur on three adjacent and then all six side faces.

This inside cover was designed by Professor Unyong Jeong of Yonsei University for a joint communication published in Angewandte Chemie International Edition (2011, 50, pp.724-727) on the fabrication of elastomeric patches with small capsules (or pockets) to hold drugs. When the elastomeric patches were compressed or stretched, the drug molecules will be forced to escape from the capsules. The release profile could be engineered by controlling the forces applied and the duration of compression or stretching.

This inside cover was designed by Dr. Xiaohu Xia for a communication published in Angewandte Chemie International Edition (2011, 50, pp.12542-12546) on the synthesis of Ag nanocrystals with concave surfaces. By maneuvering the experimental conditions, the growth of Ag nanocrystal seeds could be selectively accelerated or decelerated along specific directions to generate products with concave faces. Such concave nanocrystals were also shown with greatly improved performance for SERS applications.

This inside cover was designed by Ling Tong in Professor Ji-Xin Cheng's group at Purdue University for a joint paper published in Angewandte Chemie International Edition (2010, 49, pp. 3485-3488). It shows that Au-Ag nanocages emit bright three-photon luminescence (3PL) in the visible region when excited by a fs laser at 1290 nm. The 3PL was one order of magnitude stronger than that from pure either Au or Ag nanoparticles, making the Au-Ag nanocages a class of exciting imaging agents for the study of trafficking of nanoparticles in cells and their bio-distributions in small animals.

This cover was designed by Dr. Byungkwon Lim for a major review article published in Angewandte Chemie International Edition (2009, 48, pp. 60-103). It illustrates the connections between atomic species (in the center) and metal nanocrystals of different shapes (the outer circle) through the seeds having different numbers of twin defects (the inner circle). Once the seed is fixed, the final shape displayed by the metal nanocrystal will be determined by the growth rates along different directions through the use of a capping agent.
