An important, endemic, and imperilled tropical medicinal plant called Tabernaemontana alternifolia is successfully micropropagated in this article. On Murashige and Skoog’s media that had thidiazuron (TDZ; 2.5, 5.0, 7.5, and 10 μM) supplied, high-frequency indirect shoot regeneration was induced from the callus produced from internode explants. After 12 weeks of culture, 10 μM TDZ produced the greatest number of shoots among the diff erent TDZ concentrations examined (15.33 shoots). From the original callus, up to three subcultures could regenerate shoots. On full and half-strength MS media containing indole-3-butyric acid (IBA) after 6 weeks of culture, rooting of the shoots was seen. Rooting of shoots was facilitated by a half-strength MS medium supplemented with 5 μM IBA. After successfully being transplanted into a potting mixture including vermiculite and perlite and being raised there for 4 weeks, the plants were moved to one containing soil, sand, and farmyard manure and kept in the greenhouse. Inter simple sequence repeat (ISSR) and directed amplifi cation of minisatellite DNA (DAMD) primer assays were used to assess the genetic stability of Tabernaemontana alternifolia micropropagated plants. When randomly chosen regenerated plants were compared to donor plants, a homogenous amplifi cation profi le was found, supporting the clonal fi delity of micropropagated plants. Morphometric analysis of regenerated plants was comparable with that of mother plants suggesting the genetic fi delity of regenerated plants.

<P>The acetone gas sensor and electrochemical supercapacitor applications of bismuth oxide (Bi2O3) nanostructures, synthesised using a facile and cost-effective quaternary-beaker mediated successive ion transfer wet chemical method and deposited onto soda-lime-glass (SLG) and Ni-foam substrates, respectively, are explored. The as-deposited Bi2O3 nanostructures on these substrates exhibit polycrystalline nature and a slight change in their surface appearance (<I>i.e.</I> upright-standing nanoplates on SLG and a curvy nanosheet structure on Ni-foam), suggesting the importance of the deposition substrate in developing Bi2O3 morphologies. The Bi2O3 nanoplate gas sensor on the SGL demonstrated a room temperature sensitivity of 41%@100 ppm for acetone gas, whereas the nanosheet structure of Bi2O3 on the Ni-foam elucidated a specific capacitance of 402 F g<SUP>−1</SUP> at 2 mA cm<SUP>−2</SUP>, long-term cyclability, and rate capability with moderate chemical and environmental stability in a 6 M KOH electrolyte solution. The Bi2O3//graphite pencil-type asymmetric supercapacitor device revealed a specific capacitance as high as 43 F g<SUP>−1</SUP>, and an energy density of 13 W h kg<SUP>−1</SUP> at 793 W kg<SUP>−1</SUP> power density, turning a light emitting diode ON, with considerable full-brightness light intensity, during the process of discharging.</P>

Shinde, Pragati A.,Seo, Youngho,Ray, Chaiti,Jun, Seong Chan Elsevier 2019 ELECTROCHIMICA ACTA Vol.308 No.-

<P><B>Abstract</B></P> <P>The rational design and development of highly conductive hierarchical nanostructured materials are of great importance to improve the electrochemical performance of supercapacitors. Great efforts have been committed to the development of positive electrodes for asymmetric supercapacitors (ASC). However, it is still necessary to develop better negative electrodes for practical applications. In present investigation, a multi-walled carbon nanotubes-tungsten trioxide (MWCNT-WO<SUB>3</SUB>) hybrid nanostructure is prepared as a negative electrode for ASC. The MWCNT-WO<SUB>3</SUB> hybrid electrode is prepared using a simple two-step approach, which involves coating of MWCNTs on carbon cloth substrates followed by hydrothermal treatment to deposit WO<SUB>3</SUB> nanorods on the MWCNT-coated carbon cloth. The MWCNT-WO<SUB>3</SUB> hybrid electrode exhibits a maximum specific capacitance (areal capacitance) of 429.6 F g<SUP>−1</SUP> (1.55 F cm<SUP>−2</SUP>) and capacity retention of 94.3% after 5000 cycles, which are higher than the 155.6 F g<SUP>−1</SUP> (0.43 F cm<SUP>−2</SUP>) and 84.9% shown by pristine WO<SUB>3</SUB> in 1 M LiClO<SUB>4</SUB> electrolyte. A flexible all-solid-state ASC is self-assembled with MWCNT-WO<SUB>3</SUB> as a negative electrode, MnO<SUB>2</SUB> as a positive electrode, and PVA-LiClO<SUB>4</SUB> as a gel electrolyte. The MnO<SUB>2</SUB>//MWCNT-WO<SUB>3</SUB> ASC achieve specific capacitance of 145.6 F g<SUP>−1</SUP> at a current of 2 mA and specific energy of 39.63 Wh kg<SUP>−1</SUP> at a specific power of 546 W kg<SUP>−1</SUP>. Specifically, the ASC exhibits superior long-term cycling stability (77% over 10000 cycles) and excellent mechanical flexibility with less capacitance loss. These remarkable results demonstrate the potential of using MWCNT-WO<SUB>3</SUB> hybrid nanostructures for the fabrication of high-performance energy storage devices.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Hexagonal WO<SUB>3</SUB> nanorods are uniformly grown on MWCNT coated carbon cloth. </LI> <LI> MWCNT-WO<SUB>3</SUB> hybrid exhibits high specific capacitance of 429.6 F g<SUP>−1</SUP> at 2 mA cm<SUP>−2</SUP>. </LI> <LI> MWCNT-WO<SUB>3</SUB> hybrid maintains 94.3% initial capacitance over 5000 cycles. </LI> <LI> Flexible asymmetric supercapacitor shows high specific energy of 39.63 Wh kg<SUP>−1</SUP>. </LI> </UL> </P>

Shinde Vijaysingh,A. Dutta,A. Saxena,B. Panda,T. Maji 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8

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>

Shinde, V.V.,Jeong, Y.T. Pergamon Press ; Elsevier Science Ltd 2016 Tetrahedron letters: the international organ for t Vol.57 No.33

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.

Scalable 3-D Carbon Nitride Sponge as an Efficient Metal-Free Bifunctional Oxygen Electrocatalyst for Rechargeable Zn–Air Batteries

Shinde, Sambhaji S.,Lee, Chi-Ho,Sami, Abdul,Kim, Dong-Hyung,Lee, Sang-Uck,Lee, Jung-Ho American Chemical Society 2017 ACS NANO Vol.11 No.1

<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>

Flexible electrochromic device with simple solution processed stable silver : Nanowire based transparent conductive electrodes

Shinde, Mahesh A.,Kim, Haekyoung Elsevier 2019 Synthetic metals Vol.254 No.-

<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>
