Journal ArticleDOI
Smart Pickering water-in-oil emulsion by manipulating interactions between nanoparticles and surfactant as potential oil-based drilling fluid
TL;DR: In this article, a pH-responsive water-in-oil (W/O) emulsion system with a wide pH window was reported, based on manipulation of the interactions between fumed silica nanoparticles (NPs) and amine surfactant.
Journal ArticleDOI
Transmission electron microscopy study of Pb-depleted disks in PbTe-based alloys
TL;DR: In this article, lattice strain fields were observed in Pb-rich Pb1.3Te, Pbdeficient PbTe 1.3, and thallium (Tl)-doped Tl0.98Te crystals.
Journal ArticleDOI
Transport and mechanical properties of the double-filled p-type skutterudites La0.68Ce0.22Fe4−xCoxSb12
Tulashi Dahal,Hee Seok Kim,Sonika Gahlawat,Keshab Dahal,Qing Jie,Weishu Liu,Yucheng Lan,Kenneth W. White,Zhifeng Ren +8 more
TL;DR: In this paper, the authors reported improved thermoelectric performance of La/Ce double filled p-type skutterudites by tuning the Fe/Co ratio, leading to a peak dimensionless figure of merit (ZT) of 1.15 at ∼475°C in La0.68Ce0.22Fe3.5Co0.5Sb12.
Journal ArticleDOI
Molecular extraction in single live cells by sneaking in and out magnetic nanomaterials
Zhen Yang,Zhen Yang,Liangzi Deng,Yucheng Lan,Xiaoliu Zhang,Zhonghong Gao,Ching-Wu Chu,Ching-Wu Chu,Dong Cai,Zhifeng Ren +9 more
TL;DR: In this article, magnetized carbon nanotubes are used to sneak into and out of cell bodies under a magnetic force, which can be used to transport the intracellular GFP out at the single-cell level.
Journal ArticleDOI
Rapid photon flux switching in two-dimensional photonic crystals
TL;DR: In this article, the authors investigated the out-of-plane propagation of light in two-dimensional photonic band-gap crystals consisting of long dielectric nanorods and showed that this localization can result in a sharp transition between the state of the entire photonic crystal, and the state in which light propagates only along the defect channels.
