Chemical Methods to Knock Down the Amyloid Proteins

open access: yesMolecules, 2017
Amyloid proteins are closely related with amyloid diseases and do tremendous harm to human health. However, there is still a lack of effective strategies to treat these amyloid diseases, so it is important to develop novel methods.

Exceptional and Anisotropic Transport Properties of Photocarriers in Black Phosphorus [PDF]

open access: yesarXiv, 2015
We show that black phosphorus has room-temperature charge mobilities on the order of 10$^4$ cm$^2$V$^{-1}$s$^{-1}$, which are about one order of magnitude larger than silicon. We also demonstrate strong anisotropic transport in black phosphorus, where the mobilities along the armchair direction are about one order of magnitude larger than zigzag ...

Manipulating polarized light with a planar slab of Black Phosphorus [PDF]

open access: yesarXiv, 2017
Wave polarization contains valuable information for electromagnetic signal processing and the ability to manipulate it can be extremely useful in photonic devices. In this work, we propose designs comprised of one of the emerging and interesting two-dimensional media: Black Phosphorus.

Plant leaves inspired sunlight-driven purifier for high-efficiency clean water production

open access: yesNature Communications, 2019
Natural leaves can purify water under sunlight through a combination of osmotic pressure, transpiration, and guttation effects. Here the authors design a composite material mimicking these combined effects, achieving sunlight-driven pure water production

A comprehensive model of high-concentration phosphorus diffusion in silicon [PDF]

open access: yesarXiv, 2019
A comprehensive model of high-concentration phosphorus diffusion has been developed and simulation of phosphorus diffusion from a constant source (phosphosilicate glass) at a temperature of 890 Celsius degrees for 14.25 min. has been carried out. Such doping processes are widely used in manufacturing modern solar cells.

Solvent-assisted programming of flat polymer sheets into reconfigurable and self-healing 3D structures

open access: yesNature Communications, 2018
It is desirable to programme 2D plastic films into 3D structures without any assisting equipment. Here the authors show this programming can be achieved with a pipette, a hair dryer, and a bottle of solvent by using a commercial epoxy with a small ...
