Self-templating Scheme for the Synthesis of Nanostructured Transition-Metal Chalcogenide Electrodes for Capacitive Energy Storage
Chuan Xia,Husam N. Alshareef +1 more
TL;DR: In this article, a self-templating strategy was used to fabricate single and double-shell NiCo2S4 hollow spheres, as a promising electrode material for pseudocapacitors, which resulted in a high specific capacitance (1263 F g −1 at 2 A g − 1), remarkable rate performance (75.3% retention of initial capacitance from 2 to 60 A g−1), and exceptional reversibility with a cycling efficiency of 93.8% and 87% after 10,000 and 20,000 cycles, respectively, at a

Adsorption and Desorption Behaviors of DNA with Magnetic Mesoporous Silica Nanoparticles
Xu Li,Jixi Zhang,Hongchen Gu +2 more
TL;DR: A type of mesoporous silica nanoparticle that has a Fe(3)O(4) inner core and mesoporus silica shell is synthesized that offers a convenient platform to manipulate the DNA adsorption and desorption processes as it can be easily separated from solution by applying a magnetic field.

Nearly Monodisperse Tungstate MWO4 Microspheres (M = Pb, Ca): Surfactant-Assisted Solution Synthesis and Optical Properties
TL;DR: In this paper, nearly monodisperse microspheres of tetragonal tungstate (MWO4, M = Pb, Ca) composed of subunits with different shapes have been found to be sensitive to reaction conditions and could be tuned by controlling the reaction conditions.

Water‐Stable, Magnetic Silica–Cobalt/Cobalt Oxide–Silica Multishell Submicrometer Spheres
TL;DR: In this paper, a method to produce monodisperse magnetic composite spheres with diameters from less than 100nm to more than 1μm in water solution is reported, consisting of a dielectric silica core and a cobalt/cobalt oxide shell which can be protected from further oxidation with an outer shell of silica or, alternatively, they can be covered with the polymer polyvinylpyrrolidone as a stabilizer.

Stochastic nanoroughness modulates neuron–astrocyte interactions and function via mechanosensing cation channels
TL;DR: The finding that regions of amyloid plaque buildup in Alzheimer’s involve changes to tissue nanoroughness provides a link between nanoscale physical cues and loss of function in neurons and may have implications in uncovering the factors that promote neurodegenerative diseases.
