Tubular Sensor with Multi-Axial Strain Sensibility and Heating Capability Based on Bio-Mimic Helical Networks

Li, Yijun; Zhang, Kailin; Nie, Min; Wang, Qi

Sensors are crucial in industrial robotics and smart production line owing to the basic needs for human–machine communication and real-time monitoring. However, a lack of versatile sensing capability and multifunctionalities are still two urgent bottlenecks for current sensors to break through. In this study, from the biomimic perspective, helical and…

Morphological Evolution of Tetrachlorinated Perylene Bisimides with Lengthy Alkyl Substituent Polycrystalline Thin Films during Reversible Phase Transitions

Xin, Rui; Wang, Shaojuan; Zeng, Cheng; Ji, Andong; Zhang, Jie; Ren, Zhongjie; Jiang, Wei; Wang, Zhaohui; Yan, Shouke

The phase behavior and related morphological evolution of thin films of lengthy alkyl substituted core-tetrachlorinated perylene bisimide (C18-4ClPBI), a large ?-conjugated molecule, have been studied. It is found that the C18-4ClPBI can exist in two different crystalline phases depending on temperature, which transform reversibly in heating and cooling processes. The…

An in situ SAXS investigation of the formation of silver nanoparticles and bimetallic silver–gold nanoparticles in controlled wet-chemical reduction synthesis

F. Garcia, Paulo R. A.; Prymak, Oleg; Grasmik, Viktoria; Pappert, Kevin; Wlysses, Wagner; Otubo, Larissa; Epple, Matthias; P. Oliveira, Cristiano L.

We present a study on the formation of silver (Ag) and bimetallic silver–gold (AgAu) nanoparticlesmonitored by in situ SAXS as well as by ex situ TEM, XRD and UV-vis analysis in a flow reactor at controlled reaction temperature. The formation mechanism of the nanoparticles is derived from the structural parameters…

Facile Route for the Fabrication of Polypropylene Separators for Lithium-Ion Batteries with High Elongation and Strong Puncture Resistance

Kang, Jian; Chen, Dandan; Xiong, Bijin; Zheng, Nan; Yang, Feng; Xiang, Ming; Zheng, Zhuo

A facile route for fabrication of polypropylene separators for lithium-ion batteries with high elongation and strong puncture resistance has been proposed in this work. Polypropylene separators immersed in paraffin wax have been prepared to introduce small molecules into separators. The influence of small molecules on mechanical properties of separators is…

Ultrathin Homogenous AuNP Monolayers as Tunable Functional Substrates for Surface-Assisted Laser Desorption/Ionization of Small Biomolecules

Liu, Zhen; Zhang, Peng; Kister, Thomas; Kraus, Tobias; Volmer, Dietrich A.

A series of ultrathin, homogenous gold nanoparticle (AuNP) substrates for surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) were prepared using a simple air/water interface approach. These SALDI substrates enabled soft ionization and provided significant improvements in terms of signal intensities and reduced background levels in comparison to other AuNP morphologies for…

Biomimetic Mineralized Organic–Inorganic Hybrid Macrofiber with Spider Silk-Like Supertoughness

Yu, Yadong; He, Yan; Mu, Zhao; Zhao, Yueqi; Kong, Kangren; Liu, Zhaoming; Tang, Ruikang

Spider silk fibers (SSF) have a hierarchical structure composed of proteins with highly repetitive sequences and biomineralization is sophisticated in hierarchical organic–inorganic constructions. By using inorganic hydroxyapatite (HAP) and organic polyvinyl alcohol (PVA) to simulate the rigid crystalline and flexible amorphous protein blocks of SSF, respectively, biomimetic mineralization is…

Time resolved alkali silicate decondensation by sodium hydroxide solution

Dupuis, Romain; Rodrigues, Donatien Gomes; Champenois, Jean-Baptiste; Pellenq, Roland; Poulesquen, Arnaud

Silica is by far the chemical compound the most widespread and used around the world: as a raw product in the buildings and roads industry, as concrete, or as a processed product in the manufacture of glass, ceramics or zeolites. In alkali silicate solutions – often used to synthesize those…

Local mobility in electrochemically inactive sodium in hard carbon anodes after the first cycle

Jensen, Anders C. S.; Olsson, Emilia; Au, Heather; Alptekin, Hande; Yang, Zhengqiang; Cottrell, Stephen; Yokoyama, Koji; Cai, Qiong; Titirici, Maria-Magdalena; Drew, Alan J.

Sodium ion batteries are a promising alternative to current lithium ion battery technology, providing relatively high capacity and good cycling stability at low cost. Hard carbons are today the anodes of choice but they suffer from poor rate performance and low initial coulombic efficiency. To improve the understanding of the…

Effect of the substrate temperature during gold-copper alloys thin film deposition by magnetron co-sputtering on the dealloying process

Chauvin, Adrien; Horak, Lukas; Duverger-Nédellec, Elen; Dopita, Milan; Tessier, Pierre-Yves; El Mel, Abdel-Aziz

Nanoporous gold is of great interest for many applications due to its three dimensional interconnected porosity at nanoscale. Among all currently use techniques to obtain nanoporous gold, dealloying is one of the most used method to create a well-controlled nanoporous morphology. Only few studies report on the creation of nanoporous…
