Current Issue:Volume 13, Issue 48Volume 13, Issue 47Volume 13, Issue 46Volume 13, Issue 45Special Issue: Energy and Optoelectronic Related N...Volume 13, Issue 44Free ColorVideo AbstractsXueyan Feng, Xiuyu Wang, Di Zhang, Feng Feng, Li Yao and Guiping MaVersion of Record online: 22 DEC 2017 | DOI: 10.1002/smll.Monodisperse multifunction macroporous particles are prepared through one-step self-emulsification using spontaneously formed high internal phase emulsions as templates. Dual component emulsifiers of polystyrene-b-poly(4-vinylpyridine) copolymers and Fe3O4 nanoparticles also serve as functional components with pH- and magnetic responsiveness. These macroporous particles hold great promise for practical applications in controllable release and delivery processes. Youngdo Jeong, Gulen Yesilbag Tonga, Bradley Duncan, Bo Yan, Riddha Das, Chonticha Sahub and Vincent M. RotelloVersion of Record online: 22 DEC 2017 | DOI: 10.1002/smll.Encapsulation of transition metal catalysts into the monolayers of gold nanoparticles generates nanoreactors that provide water solubility and a protective environment for the catalysts. Feng Li and Zhen ZhouVersion of Record online: 21 DEC 2017 | DOI: 10.1002/smll.The latest developments of micro/nanostructured electrode materials for sodium-based electrochemical energy storage devices, sodium ion batteries, and sodium ion capacitors, are reviewed. Especially, the rational design of unique nanocomposites with high thermodynamic stabilities and fast kinetics are comprehensively summarized. On the basis of the recent achievements, the remaining challenges with respect to fundamental investigations and commercialized applications are also discussed along with the prospects of sodium-based energy storage systems. Yi Zhao, Jinzhang Liu, Dezhi Zheng, Bin Wang, Mingjun Hu, Jiangbo Sha and Yan LiVersion of Record online: 21 DEC 2017 | DOI: 10.1002/smll.Aromatic molecules of hydrolyzed polyimide are used to functionalize N-doped graphene (NG) with the aim to introducing pseudocapacitance in addition to the electric double layer capacitance. As a result, paper-like graphene films with adsorbed functional molecules exhibit high specific capacitance, which are about 1.5 times higher than that of NG films without functionalization. Yaru Liang, Wei-Hong Lai, Zongcheng Miao and Shu-Lei ChouVersion of Record online: 20 DEC 2017 | DOI: 10.1002/smll.To explore electrode materials with long cycle life and high energy density, a wide range of nanocomposites have been applied to the anodes and cathodes of sodium batteries. Due to the advantages of nanoscale composites, there have been great improvements in the electrical performance of sodium&ion batteries. The development of nanocomposite materials for sodium&ion batteries is reviewed here./ Joe McConnell

Professional Interests
Dr. McConnells research interests include snow and global-scale hydrology, ice core and atmospheric chemistry, glaciology, and ice sheet mass balance - with particular emphasis on understanding the role of human activities in global climate and sea level change. Current NSF, NASA, and internally funded research projects include ice core chemistry-based studies in Greenland, Antarctica, and the Americas. Central to this research are national and international collaborations (e.g., British Antarctic Survey, Australian Antarctic Division, Instituto Antrtico Argentino, Norwegian Polar Institute) and DRIs unique ultra-trace ice core analytical laboratory. This laboratory is capable of simultaneously measuring in ice cores a broad suite of elements in quantities as low as parts per quadrillion and at very high depth resolution. McConnells group also conducts collaborative research in hydrology and water balance in snow-dominated, semiarid regions such as the American West as part of the NSF-funded SAHRA Science and Technology Center.
