Influence of Iron Salt Anions on Formation and Oxygen Reduction Activity of Fe/N-Doped Mesoporous Ca

Fretz, Samuel J.; Janson, Caroline; Rosas-Arbelaez, Walter; Palmqvist, Anders E. C.

Influence of Iron Salt Anions on Formation and Oxygen Reduction Activity of Fe/N-Doped Mesoporous Carbon Fuel Cell Catalysts Fretz, Samuel J.; Janson, Caroline; Rosas-Arbelaez, Walter; Palmqvist, Anders E. C. Doping carbon materials with transition metal ions can greatly expand their utility, given these metal ions’ unique catalytic activity, for example, in oxygen reduction in proton exchange membrane fuel cells. Unlike main group dopants, a counter anion to the metal cation must be selected and this choice has hitherto received…

Emergence of lead halide perovskite colloidal dispersions through aggregation and fragmentation: ins

Pratap, Shambhavi; Keller, Elisabeth; Müller-Buschbaum, Peter

Emergence of lead halide perovskite colloidal dispersions through aggregation and fragmentation: insights from the nanoscale to the mesoscale Pratap, Shambhavi; Keller, Elisabeth; Müller-Buschbaum, Peter The structural and optoelectronic properties of mixed halide perovskite colloidal precursor dispersions are investigated. With increasing concentration, we observe four stages of growing structures, which affect the thin film morphology: (I) nanoparticles, (II) increasing size of nanoparticles, (III) formation of large aggregates/complex clusters and (IV) fragmentation of large…

Revisiting the Dissolution of Cellulose in NaOH as “Seen” by X-rays

Martin-Bertelsen, Birte; Andersson, Erika; Köhnke, Tobias; Hedlund, Artur; Stigsson, Lars; Olsson, Ulf

Revisiting the Dissolution of Cellulose in NaOH as “Seen” by X-rays Martin-Bertelsen, Birte; Andersson, Erika; Köhnke, Tobias; Hedlund, Artur; Stigsson, Lars; Olsson, Ulf Cotton production is reaching a global limit, leading to a growing demand for bio-based textile fibers produced by other means. Textile fibers based on regenerated cellulose from wood holds great potential, but in order to produce fibers, the components need to be dissolved in suitable solvents. Furthermore, the dissolution process…

Novel S-doped ordered mesoporous carbon nanospheres toward advanced lithium metal anodes

Zhang, Fei; Liu, Xiaoyan; Yang, Menghua; Cao, Xiaoqing; Huang, Xingyu; Tian, Yue; Zhang, Fang; Li, Hexing

Novel S-doped ordered mesoporous carbon nanospheres toward advanced lithium metal anodes Zhang, Fei; Liu, Xiaoyan; Yang, Menghua; Cao, Xiaoqing; Huang, Xingyu; Tian, Yue; Zhang, Fang; Li, Hexing Lithium metal anode has been considered as an ideal anode for the next generation lithium batteries owing to its high energy density. However, its practical application is still limited by the low Coulombic efficiency and poor safety performance due to the lithium dendrites caused by uncontrollable lithium deposition and unstable…

Identifying the Superstability Landscapes of Clay–Carbon Nanosheet Suspensions

Kumar, Sanjay; Harikrishnan, G.

Identifying the Superstability Landscapes of Clay–Carbon Nanosheet Suspensions Kumar, Sanjay; Harikrishnan, G. Using a combination of several experiments, we identify the landscapes of the widely reported superstability of suspensions formed by codispersion of nanosheets of clay and carbon. Primarily, two distinct, abrupt transitions within this superstability are observed. This observation made on a series of model laponite–graphene oxide superstable two-dimensional sheet suspensions…

Effects of Hairy Nanoparticles on Polymer Crystallization Kinetics

Jimenez, Andrew M.; Krauskopf, Alejandro A.; Pérez-Camargo, Ricardo A.; Zhao, Dan; Pribyl, Julia; Jestin, Jacques; Benicewicz, Brian C.; Müller, Alejandro J.; Kumar, Sanat K.

Effects of Hairy Nanoparticles on Polymer Crystallization Kinetics Jimenez, Andrew M.; Krauskopf, Alejandro A.; Pérez-Camargo, Ricardo A.; Zhao, Dan; Pribyl, Julia; Jestin, Jacques; Benicewicz, Brian C.; Müller, Alejandro J.; Kumar, Sanat K. We previously showed that nanoparticles (NPs) could be ordered into structures by using the growth rate of polymer crystals as the control variable. In particular, for slow enough spherulitic growth fronts, the NPs grafted with amorphous polymer chains are selectively moved into the interlamellar, interfibrillar, and interspherulitic zones of a…
