Precise Control of Intracellular Drug Release and Anti-Tumor Activity of Biodegradable Micellar Drugs Via Reduction-Sensitive Shell-Shedding
The reduction-sensitive shedding of hydrophilic shells has recently emerged as a simple, effective and general approach to achieve markedly improved intracellular drug release from micelles. Here, the effects of disulfide content on reduction-sensitivity, triggered drug release and the anti-tumor activity of shell-sheddable micelles self-assembled from a mixture of reducible poly(ethylene glycol)&...

Cyclodextrin-Overhanging Hyperbranched Core-Double-Shell Miktoarm Architectures: Synthesis and Gradient Stimuli-Responsive Properties
We report the synthesis and gradient stimuliresponsive
properties of cyclodextrin-overhanging hyperbranched
core-double-shell miktoarm architectures. A ionic
hyperbranched poly(b-cyclodextrin) (b-CD) core was firstly synthesized
via a convenient ‘‘A2þB3’’ approach. Double-layered
shell architectures, composed of poly(N-isopropyl acrylamide)
(PNIPAm) and poly(N,N...

Fabrication of promising LiFePO4/C composite with a core-shell structure by a moderate in situ carbothermal reduction method
How to improve the power density of olivine LiFePO4 has recently become one of the most attractive topics of both scientific and industrial interests. Therefore, nanostructured electrodes have been widely investigated to satisfy such needs. However, the complicated and high-temperature sintering process is usually involved for preparing high-performance cathode materials based on high-quality crys...
