Although linear accelerations are an important common component of the diversity fish locomotor behaviors, acceleration is one least-understood aspects propulsion. Analysis behavior in fishes with both spiny and soft-rayed median fins demonstrates that fin area actively modulated when accelerate. We implemented undulatory biomimetic robotic model manufactured using multimaterial three-dimensional printing-a spiny-rayed dorsal fin, dorsal/anal fins, a caudal fin-whose stiffnesses span three...
An interface stabilizer based on alkylation-functionalized fullerene derivatives, [6, 6]-Phenyl-C61-butyric acid (3,5-bis(octyloxy)phenyl)methyl ester (PCB-C8oc), was successfully synthesized and applied for the active layer of Organic Photovoltaics (OPVs). The PCB-C8oc can replace part phenyl-C61-buty-ric methyl (PCBM) be distributed poly(3-hexylthiophene) (P3HT) PCBM to form P3HT/PCBM/PCB-C8oc ternary blends, leading thermally stable efficient organic photovoltaics. octyl groups exhibit...
Organic/amorphous silicon (a-Si) hybrid tandem solar cells have the potential to provide a highly efficient low-cost photovoltaic technology using abundant elements, and is adaptable large-scale processes. With their high open-circuit voltage (Voc) adaptability broad spectrum, organic/a-Si devices offer significantly improved performance. We shown that with complementary organic absorber can exhibit power conversion efficiency (PCE) of up 7.5%, fill factor (FF) 72.3% Voc almost equivalent...
Solid alcohol 1-pyrenemethanol (PyM) was first introduced to modify the zinc oxide (ZnO) layer which is used in inverted polymer solar cells (PSCs) as a cathode buffer (CBL). As low-cost industrial product, PyM can surface defects and improve electron mobility of ZnO CBL, be attributed self-assembly on due hydrogen bonds conjugated structure PyM. With blend PTB7:PC71BM active layer, device with ZnO/PyM CBL exhibited notable power conversion efficiency (PCE) 8.26%, better than that control...
Efficient inverted polymer solar cells (PSCs) were constructed by utilizing a conjugated polyelectrolyte PFEOSO3Na and zinc oxide to modify the indium tin (ITO) electrode. The ITO electrode modified possesses high transparency, increased electron mobility, smoothened surface, lower work function. PTB7:PC71BM PSCs containing achieved power conversion efficiency (PCE) of 8.49%, exceeding that control device ZnO (7.48%). Especially, PCE-10:PC71BM PCE up 9.4%. These results demonstrate useful...
The power conversion efficiency of a PTB7:PC<sub>71</sub>BM polymer solar cell was improved up to 9.1% by combination methanol treatment followed conjugation water- or alcohol-soluble polyelectrolyte thin layer.
Abstract. Earth and other terrestrial icy planetary bodies deform visco-elastically under various forces. Numerical modeling plays a critical role in understanding the nature of dynamic deformation processes. This article introduces newly developed, open-source package, CitcomSVE-3.0, which efficiently solves visco-elastic bodies. Based on its predecessor, CitcomSVE-2.1, CitcomSVE-3.0 is updated to account for elastic compressibility depth-dependent density, are particularly important...
A series of TiO2 nanorod arrays were obtained by hydrothermal reaction, then the morphologies characterized and analysed. In light polymerization condition, different chiral nematic liquid crystalline (N*-LCs) media combined to prepare broad-band reflectors. By adjusting length interval size arrays, reflection spectra positions reflected spectrum bandwidth can be controlled accordingly. As a result, effect temperatures on in N*-LC composite system has been investigated. Potential...
Abstract The aim of this work was to investigate the role microwave parameters and moisture content on free volume (FV) changes rice starch by positron annihilation lifetime spectroscopy analysis (PALS) explore potential relationship between FV physicochemical properties starch. Microwave heating water molecules lead increasing However, result is largely influenced plasticization molecule. anti-plasticization caused evaporation resulting in a decrease size concentration during heating....

Tandem blade technology has become an effective method to break the load limit of conventional aerodynamic configurations. To expand application range tandem blades, supersonic flow characteristic was studied and optimal design conducted by using a computational fluid dynamics (CFD) solver, with inflow Mach number 1.2. The main conclusions follow: (1) loss is difficult control because complicated structures inflow; (2) forward dominates overall in whole operating conditions; (3) profile...
Recent advances in understanding fish locomotion with robotic devices have included the use of different prototypes that swim at a controlled but constant swimming speeds. However, speed even steadily live fishes is not because commonly accelerate and decelerate throughout tail beat cycles. In this paper, we implement bass body-shaped robot, programmed to display carangiform locomotion.
