In the last few decades there have been several papers in the area of swarm robotics, in which researchers have considered the capture or transfer of an object using a large number of robots or agents. However in these cases the capture and transportation processes have not been optimized in terms of the minimum number of agents required or the best paths. We have earlier proposed the optimal capture and transportation of a moving object using only four agents. This paper is a further extension of our earlier work in which we experimentally evaluate the performance of the multi agent system to capture and transfer a moving 2D prismatic object avoiding obstacles using the least number of agents.A closed loop system is developed using a vision system that can optimally find the goal points on a moving object and control the robots to capture the object. After the object is captured it is optimally guided to the goal point. The results prove that the system can operate autonomously and in real time.

<P><B>Abstract</B></P> <P>This paper reports the effect of electron beam irradiation on CuO thin films synthesized by the successive ionic layer adsorption and reaction (SILAR) method on copper foil for supercapacitor and biocompatibility application. Pristine and irradiated samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, and electrochemical study. Pristine and irradiated CuO films were pure monoclinic phase, with uniform nanostructures over the whole copper foil. After irradiation, CuO samples had formed innovative nanostructures. Biocompatibility of pristine and irradiated CuO samples suggest that CuO sample is non-toxic and ecofriendly. The specific capacitance of pristine and irradiated CuO strongly depends on surface morphology, and CuO electrodes after irradiation showed superior performance than pristine CuO. The highest specific capacitance of the 20kGy irradiated CuO nanoflowers exceeded 511Fg<SUP>−1</SUP> at 10mVs<SUP>−1</SUP> in 1M KOH electrolyte. Irradiated CuO samples also showed lower ESR, and were superior to other report electrical energy storage materials.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Novel route for the synthesis of pure CuO thin films. </LI> <LI> Different nanostructure of pure CuO and irradiated CuO electrode. </LI> <LI> 20kGy irradiated CuO electrode offer high surface area. </LI> <LI> 20kGy irradiated CuO electrode shows excellent supercapacitive properties. </LI> </UL> </P>

<P>An ultrasound-promoted, environmentally benign, efficient procedure has been developed for the synthesis of biologically active tetrahydro-1H-indol-4(5H)-one using heterogeneous BrOnsted base silica sodium carbonate (SSC) as a catalyst under solvent-free conditions. In comparison to the conventional methods, this efficient green protocol provides remarkable advantages such as good to excellent yields, shorter reaction time, low cost, and easy workup procedure and bypasses the use of hazardous transition-metal catalysts and organic solvents.

A green and efficient procedure has been developed for the synthesis of densely functionalized tetrahydroindazolo[3,2-b]quinazoline catalyzed by iron fluoride under sonication in solvent-free condition. In comparison to the conventional methods, this efficient green protocol provides remarkable advantages such as good to excellent yields, shorter reaction time, low cost, easy work-up procedure, and bypass for use of solvent and column chromatography. One of the important and interesting advantages of this methodology compared to previous method is that acyclic 1,3-dicarbonyl also gives the desired product which was not possible using the previously reported methodologies.

<P>Rational design of efficient and durable bifunctional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) electrocatalysts is critical for rechargeable metal–air batteries. Here, we developed a facile strategy for fabricating three-dimensional phosphorus and sulfur codoped carbon nitride sponges sandwiched with carbon nanocrystals (P,S-CNS). These materials exhibited high surface area and superior ORR and OER bifunctional catalytic activities than those of Pt/C and RuO<SUB>2</SUB>, respectively, concerning its limiting current density and onset potential. Further, we tested the suitability and durability of P,S-CNS as the oxygen cathode for primary and rechargeable Zn–air batteries. The resulting primary Zn–air battery exhibited a high open-circuit voltage of 1.51 V, a high discharge peak power density of 198 mW cm<SUP>–2</SUP>, a specific capacity of 830 mA h g<SUP>–1</SUP>, and better durability for 210 h after mechanical recharging. An extraordinary small charge–discharge voltage polarization (∼0.80 V at 25 mA cm<SUP>–2</SUP>), superior reversibility, and stability exceeding prolonged charge–discharge cycles have been attained in rechargeable Zn–air batteries with a three-electrode system. The origin of the electrocatalytic activity of P,S-CNS was elucidated by density functional theory analysis for both oxygen reactions. This work stimulates an innovative prospect for the enrichment of rechargeable Zn–air battery viable for commercial applications such as armamentaria, smart electronics, and electric vehicles.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2017/ancac3.2017.11.issue-1/acsnano.6b05914/production/images/medium/nn-2016-05914q_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn6b05914'>ACS Electronic Supporting Info</A></P>

<P><B>Abstract</B></P> <P>Electrochromic devices (ECDs) are considered a prominent technology for next-generation electronic applications. Recently, considerable efforts have been undertaken to fabricate indium-tin-oxide-free (ITO-free) flexible ECDs. In this study, we fabricated ITO-free flexible ECDs by using flexible transparent conductive electrodes (TCE) based on silver nanowires (AgNWs) and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) on a polyethylene terephthalate (PET) substrate (PEDOT:PSS/AgNW/PET). The flexible TCE exhibited 17.66 Ω/sq of sheet resistance with 93.73% transmittance (at λ =550 nm). In addition, the TCE showed stable electrical performances under various environmental conditions, such as different light source, in hot humid air and in presence of electrolyte. The PEDOT:PSS/AgNW/PET based flexible ECD demonstrated a maximum transmittance contrast (ΔT<SUB>max</SUB>) of 79.62% (at λ = 700 nm) with a coloration efficiency of 46.84 cm<SUP>2</SUP> C<SUP>−1</SUP> in the range from -1.5 to 0 V. In addition, the ECD displayed better cyclic stability over 100 cycles. These results affirm that PEDOT:PSS/AgNW/PET-based flexible ECD with stable electrochromic performance could be considered as a potential replacement of ITO in next-generation flexible electronic applications.</P>

<P>Development of metal-free catalysts is of huge interest for photocatalytic water splitting using solar energy. Here, we report a composite nano-material consisting of sulfur-incorporated graphitic carbon nitride grown on the surface of sulfur/selenium co-doped graphene (CNS:S-Se-Gr) hybrid as a high-performance metal-free photocatalyst for the degradation of methylene blue (MB) and hydrogen evolution (by water splitting) in the presence of sacrificial donors under visible light illumination. The recorded MB degradation efficiency is about 98% in 3.5 h. The achieved highest hydrogen evolution rates for CNS:S-Se-Gr hybrid in sodium sulfite and lactic acid solution are about 1.58 and 2.59 mmol g(-1) h(-1) respectively. This hybrid material exhibits significantly enhanced photocatalytic H-2 evolution activity (9-fold) compared with that of pristine g-C3N4. Also, we proposed a possible mechanism for charge separation and transfer in the CNS:S-Se-Gr catalyst. Additionally, modulation of the electronic band structure has been investigated. These results suggest that the CNS:S-Se-Gr metal-free hybrid has great potential as a promising photocatalyst for the water splitting. (C) 2015 Elsevier Ltd. All rights reserved.</P>
