Iodine‐Doped Sodium Vanadate Cathode for Improved Zn Ion Diffusion Kinetics

open access: yesAdvanced Materials, EarlyView.
An iodine‐doping strategy is developed to modify the Na2V6O16·3H2O cathode for aqueous zinc‐ion batteries, effectively reducing the electrostatic interaction between zinc ions and the host structure. This modification enables faster diffusion and higher storage capacity of zinc ions. Abstract The electrostatic interaction between zinc ions and the host

Plaque‐Targeted Delivery of Fluoride‐Free MXene Nanozyme for Alleviating Atherosclerosis via Sonocatalytic Therapy

open access: yesAdvanced Materials, EarlyView.
This work has developed a dual enzyme‐mimicking and ultrasound‐responsive Nb2C‐Pt@HA‐PEG nanozyme. ROS‐eliminating and anti­inflammatory capability of Nb2C‐Pt@HA‐PEG under US irradiation are demonstrated on macrophages and endothelial cells in vitro. Nb2C‐Pt@HA‐PEG‐mediated sonocatalytic therapy exerts an outstanding anti‐atherosclerosis efficacy by ...

Closed Locally Minimal Networks on the Surfaces of Convex Polyhedra

open access: yesМоделирование и анализ информационных систем, 2013
Closed locally minimal networks can be viewed as “branching” closed geodesics. We study such networks on the surfaces of convex polyhedra and discuss the problem of describing the set of all convex polyhedra that have such networks.

Determining All Universal Tilers

open access: yes, 2011
A universal tiler is a convex polyhedron whose every cross-section tiles the plane. In this paper, we introduce a certain slight-rotating operation for cross-sections of pentahedra.
