Methyllithium‐Doped Naphthyl‐Containing Conjugated Microporous Polymer with Enhanced Hydrogen Storage Performance

23-Apr-2016 | Dan Xu, Lei Sun, Gang Li, Jin Shang, Rui‐Xia Yang, Wei‐Qiao Deng, Chemistry - A European Journal, 2016

Abstract Hydrogen storage is a primary challenge for using hydrogen as a fuel. With ideal hydrogen storage kinetics, the weak binding strength of hydrogen to sorbents is the key barrier to obtain decent hydrogen storage performance. Here, we reported the rational synthesis of a ...

Sustainability, Vol. 8, Pages 402: The Sustainable Improvement of Manufacturing for Nano-Titanium

23-Apr-2016 | Wang, Chia-Nan ; Lin, Han-Sung ; Hsueh, Ming-Hsien ; Wang, Yen-Hui ; Vu, Thi-Hao ; Lin, Tsung-Fu, Sustainability, 2016

Scientists have found that nanomaterials possess many outstanding features in their tiny grain structure compared to other common materials. Titanium at the nano-grain scale shows many novel characteristics which demonstrate suitability for use in surgical implants. In general, equal channel ...

Sensors, Vol. 16, Pages 572: A High-Speed Vision-Based Sensor for Dynamic Vibration Analysis Using Fast Motion Extraction Algorithms

22-Apr-2016 | Zhang, Dashan ; Guo, Jie ; Lei, Xiujun ; Zhu, Changan, Sensors, 2016

The development of image sensor and optics enables the application of vision-based techniques to the non-contact dynamic vibration analysis of large-scale structures. As an emerging technology, a vision-based approach allows for remote measuring and does not bring any additional mass to the ...

[Feature] Rubber workers on the front lines

22-Apr-2016 | Leslie Roberts, Science , 2016

In the Greater Mekong subregion, the people at highest risk for malaria are those who work in the forest fringe where the mosquito vectors thrive—rubber tappers, for instance, or miners, ethnic minorities who live along the messy international borders. Wiping out the malaria parasite in the ...

Exceptional Morphology-Preserving Evolution of Formamidinium Lead Triiodide Perovskite Thin Films via Organic-Cation Displacement

22-Apr-2016 | Yuanyuan Zhou; Mengjin Yang; Shuping Pang; Kai Zhu; Nitin P. Padture, Journal of the American Chemical Society, 2016

Here we demonstrate a radically different chemical route for the creation of HC(NH2)2PbI3 (FAPbI3) perovskite thin films. This approach entails a simple exposure of as-synthesized CH3NH3PbI3 (MAPbI3) perovskite thin films to HC(═NH)NH2 (formamidine or FA) gas at 150 °C, which leads to rapid ...

Molybdenum–Bismuth Bimetallic Chalcogenide Nanosheets for Highly Efficient Electrocatalytic Reduction of Carbon Dioxide to Methanol

21-Apr-2016 | Xiaofu Sun, Qinggong Zhu, Xinchen Kang, Huizhen Liu, Qingli Qian, Zhaofu Zhang, Buxing Han, Angewandte Chemie International Edition, 2016

Abstract Methanol is a very useful platform molecule and liquid fuel. Electrocatalytic reduction of CO2 to methanol is a promising route, which currently suffers from low efficiency and poor selectivity. Herein we report the first work to use a Mo‐Bi bimetallic chalcogenide (BMC) as an ...

Effect of processing methods on electrical percolation and electromagnetic shielding of PC/MWCNTs nanocomposites

21-Apr-2016 | S. M. Seyedi Ghezghapan, A. Javadi, Polymer Composites, 2016

Nanocomposites of polycarbonate (PC)/multiwalled carbon nanotubes (MWCNTs) containing 0.5–3wt% of MWCNTs were prepared via two methods of melt mixing and solution mixing. The effect of CNT content and processing methods on electrical and electromagnetic properties of nanocomposite samples were ...

Energies, Vol. 9, Pages 304: Decreasing NOx of a Low-Speed Two-Stroke Marine Diesel Engine by Using In-Cylinder Emission Control Measures

21-Apr-2016 | Feng, Liyan ; Tian, Jiangping ; Long, Wuqiang ; Gong, Weixin ; Du, Baoguo ; Li, Dan ; Chen, Lei, Energies, 2016

The authors applied one-dimensional (1-D) simulation and 3-D Computational Fluid Dynamics (CFD) simulation to evaluate the potential of in-cylinder control methods on a low-speed 2-stroke marine engine to reach the International Maritime Organization (IMO) Tier 3 NOx emissions standards. Reducing ...

Energies, Vol. 9, Pages 300: Preliminary Development of a Free Piston Expander–Linear Generator for Small-Scale Organic Rankine Cycle (ORC) Waste Heat Recovery System

20-Apr-2016 | Li, Gaosheng ; Zhang, Hongguang ; Yang, Fubin ; Song, Songsong ; Chang, Ying ; Yu, Fei ; Wang, Jingfu ; Yao, Baofeng, Energies, 2016

A novel free piston expander-linear generator (FPE-LG) integrated unit was proposed to recover waste heat efficiently from vehicle engine. This integrated unit can be used in a small-scale Organic Rankine Cycle (ORC) system and can directly convert the thermodynamic energy of working fluid into ...
