Coupled Triboelectric Nanogenerator Networks for Efficient Water Wave Energy Harvesting

19.01.2018 | Liang Xu; Tao Jiang; Pei Lin; Jia Jia Shao; Chuan He; Wei Zhong; Xiang Yu Chen; Zhong Lin Wang, ACS Nano, 2018

Water wave energy is a promising clean energy source, which is abundant but hard to scavenge economically. Triboelectric nanogenerator (TENG) networks provide an effective approach toward massive harvesting of water wave energy in oceans. In this work, a coupling design in TENG networks for such ...

Carbon Nanotube Web with Carboxylated Polythiophene “Assist” for High-Performance Battery Electrodes

19.01.2018 | Yo Han Kwon; Jung Jin Park; Lisa M. Housel; Krysten Minnici; Guoyan Zhang; Sujin R. Lee; Seung Woo Lee; Zhongming Ch ..., ACS Nano, 2018

A carbon nanotube (CNT) web electrode comprising magnetite spheres and few-walled carbon nanotubes (FWNTs) linked by the carboxylated conjugated polymer, poly[3-(potassium-4-butanoate) thiophene] (PPBT), was designed to demonstrate benefits derived from the rational consideration of electron/ion ...

Folding Graphene Film Yields High Areal Energy Storage in Lithium-Ion Batteries

19.01.2018 | Bin Wang; Jaegeon Ryu; Sungho Choi; Gyujin Song; Dongki Hong; Chihyun Hwang; Xiong Chen; Bo Wang; Wei Li; Hyun-Kon S ..., ACS Nano, 2018

We show that a high energy density can be achieved in a practical manner with freestanding electrodes without using conductive carbon, binders, and current collectors. We made and used a folded graphene composite electrode designed for a high areal capacity anode. The traditional thick graphene ...

Cancer Cell Membrane-Biomimetic Nanoprobes with Two-Photon Excitation and Near-Infrared Emission for Intravital Tumor Fluorescence Imaging

19.01.2018 | Yanlin Lv; Ming Liu; Yong Zhang; Xuefei Wang; Fan Zhang; Feng Li; Wei-Er Bao; Jie Wang; Yuanlin Zhang; Wei Wei; Guan ..., ACS Nano, 2018

Biomimetic fluorescent nanoprobes capable of emitting near-infrared (NIR) fluorescence (λmax ≈ 720 nm) upon excitation of 800 nm light were developed. The key conjugated polymer enabled two-photon absorption and Förster resonance energy transfer (FRET) processes within the nanoprobes, which ...

Double-Channel Piezotronic Transistors for Highly Sensitive Pressure Sensing

18.01.2018 | Shuhai Liu; Longfei Wang; Zheng Wang; Yafeng Cai; Xiaolong Feng; Yong Qin; Zhong Lin Wang, ACS Nano, 2018

Piezotronic transistors (PTs) that utilize inner crystal potential generated by interface piezoelectric polarization charges as the gate voltage have great potential applications in force/pressure-triggered or controlled electronic devices, sensors, human–machine communication, and ...

Directing Nanoparticle Biodistribution through Evasion and Exploitation of Stab2-Dependent Nanoparticle Uptake

18.01.2018 | Frederick Campbell; Frank L. Bos; Sandro Sieber; Gabriela Arias-Alpizar; Bjørn E. Koch; Jörg Huwyler; Alexander Kros ..., ACS Nano, 2018

Up to 99% of systemically administered nanoparticles are cleared through the liver. Within the liver, most nanoparticles are thought to be sequestered by macrophages (Kupffer cells), although significant nanoparticle interactions with other hepatic cells have also been observed. To achieve ...

Three-Dimensional Printing Hollow Polymer Template-Mediated Graphene Lattices with Tailorable Architectures and Multifunctional Properties

18.01.2018 | Qiangqiang Zhang; Feng Zhang; Xiang Xu; Chi Zhou; Dong Lin, ACS Nano, 2018

It is a significant challenge to concurrently achieve scalable fabrication of graphene aerogels with three-dimensional (3D) tailorable architectures (e.g., lattice structure) and controllable manipulation of microstructures on the multiscale. Herein, we highlight 3D graphene lattices (GLs) with ...

Hybridization of Lattice Resonances

18.01.2018 | Sebastian Baur; Stephen Sanders; Alejandro Manjavacas, ACS Nano, 2018

Plasmon hybridization, the electromagnetic analog of molecular orbital theory, provides a simple and intuitive method to describe the plasmonic response of complex nanostructures from the combination of the responses of their individual constituents. Here, we follow this approach to investigate ...

Ultrafast Spectral Photoresponse of Bilayer Graphene: Optical Pump–Terahertz Probe Spectroscopy

18.01.2018 | Srabani Kar; Van Luan Nguyen; Dipti R. Mohapatra; Young Hee Lee; A. K. Sood, ACS Nano, 2018

Photoinduced terahertz conductivity Δσ(ω) of Bernal stacked bilayer graphene (BLG) with different dopings is measured by time-resolved optical pump terahertz probe spectroscopy. The real part of photoconductivity Δσ(ω) (ΔσRe(ω)) is positive throughout the spectral range 0.5–2.5 THz in low-doped ...

Electrical Matching at Metal/Molecule Contacts for Efficient Heterogeneous Charge Transfer

18.01.2018 | Shino Sato; Shigeru Iwase; Kotaro Namba; Tomoya Ono; Kenji Hara; Atsushi Fukuoka; Kohei Uosaki; Katsuyoshi Ikeda, ACS Nano, 2018

In a metal/molecule hybrid system, unavoidable electrical mismatch exists between metal continuum states and frontier molecular orbitals. This causes energy loss in the electron conduction across the metal/molecule interface. For efficient use of energy in a metal/molecule hybrid system, it is ...
