However, very little research effort has been devoted to developing organic packaging materials, which are crucial for the efficient functioning of the devices. Polymer thermosets (PTs) are extensively used for the packaging of microelectronic and optoelectronic devices. Although PTs are effective in providing mechanical stability and environmental protection to devices, the removal of PTs without destroying the underlying surface is cumbersome. Facile removal of PTs is essential to reuse the expensive substrates. Herein, we report the preparation of a thermoset using an aliphatic disulfide containing cross-linker, cystamine. By varying the cross-linker concentration, the mechanical property of the thermoset was varied from ductile to brittle. The ductile thermoset was coated on metal, semiconductor and flexible substrates. The thermosets were then cleaved using a biomolecule in neutral pH. We have demonstrated that the cleavage and removal of thermosets don't affect the surface properties of the underlying substrates. Furthermore, the thermosets were coated on top of organic field effect transistors to provide environmental protection. The thermoset coated devices showed a charge carrier mobility of 5.3 x 10(-3) cm(2) V-1 s(-1). Then, the thermoset was cleaved and removed, and the substrate was reused for the fabrication of organic field effect transistors with unchanged device efficiencies.1 aArulkashmir, Arulraj1 aBhosale, Manik, E.1 aKrishnamoorthy, Kothandam  uhttps://library.ncl.res.in/content/cleavable-and-removable-polymer-thermosets-organic-field-effect-transistor-packaging-001696nas a2200157   4500008004100000022001400041245009300055210006900148260007100217300001400288490000700302520105100309100002301360700003001383856012501413       2015                        eng d  a0897-475600aChemically reduced organic small-molecule-based lithium battery with improved efficiency0 aChemically reduced organic smallmoleculebased lithium battery wi  a1155 16TH ST, NW, WASHINGTON, DC 20036 USAbAMER CHEMICAL SOCcMAR  a2121-21260 v273 a<p>Organic lithium batteries are attractive because of the possibility of fabricating lightweight and flexible devices. However, the organic lithium batteries have a few drawbacks. The specific capacity is usually lower than the theoretical capacity, which further decreases upon cycling. Often, the specific capacity is very low compared to theoretical capacity while discharging the battery at moderate and high C rates. To circumvent this issue, we chemically reduced carboxylic acid functionality substituted perylene diimide (benzoic-PDI) with hydrazine. Indeed, we found that the rate of redox reaction as well as the conductivity of the benzoic-PDI increased upon chemical reduction. The battery comprising reduced benzoic-PDI exhibits 100% Coulombic efficiency and specific capacity while discharging at 20C. The battery also exhibits very high specific energy (213 Wh/kg) and specific power (8548 W/kg). The control experiments confirm our hypothesis of using chemical reduction to improve the performance of organic lithium battery.</p>1 aBhosale, Manik, E.1 aKrishnamoorthy, Kothandam  uhttps://library.ncl.res.in/content/chemically-reduced-organic-small-molecule-based-lithium-battery-improved-efficiency-000941nas a2200181   4500008004100000022001400041245009800055210006900153260011000222300001200332490000700344520017600351100002300527700002700550700002400577700003000601856012800631       2016                        eng d  a1359-734500aConjugated porous polymers as precursors for electrocatalysts and storage electrode materials0 aConjugated porous polymers as precursors for electrocatalysts an  aTHOMAS GRAHAM HOUSE, SCIENCE PARK, MILTON RD, CAMBRIDGE CB4 0WF, CAMBS, ENGLANDbROYAL SOC CHEMISTRYcOCT  a316-3180 v523 a<p>Conjugated porous polymers were used as precursors to prepare nitrogen and sulphur doped carbon atoms, which were then used for oxygen reduction and energy storage.</p>1 aBhosale, Manik, E.1 aIllathvalappil, Rajith1 aKurungot, Sreekumar1 aKrishnamoorthy, Kothandam  uhttps://library.ncl.res.in/content/conjugated-porous-polymers-precursors-electrocatalysts-and-storage-electrode-materials-0
