Polymer/Perovskite Amplifying Waveguides for Active Hybrid Silicon Photonics
(Wiley, 2015-08)
The emission properties of hybrid halide perovskites are exploited to implement a stable and very low power operation waveguide optical amplifier integrated in a silicon platform. By optimizing its design with a poly(methyl ...
Enhanced Carrier Transport Distance in Colloidal PbS Quantum-Dot-Based Solar Cells Using ZnO Nanowires
(American Chemical Society, 2015-11)
Nanostructured solar cells are a promising area of research for the production
of low cost devices that may eventually be capable of complementing or even replacing
present technologies in the field of solar power ...
Impact of Capacitive Effect and Ion Migration on the Hysteretic Behavior of Perovskite Solar Cells
(American Chemical Society, 2015-11)
In the past five years, perovskite solar cells (PSCs) based on organometal halide perovskite have exhibited extraordinary photovoltaic (PV) performance. However, the PV measurements of PSCs have been widely recognized to ...
On the different sources of cooperativity in pH titrating sites of a membrane protein channel
(EDP SciencesSocietà Italiana di FisicaSpringer-Verlag, 2016)
Cooperative interactions play a central role in the regulation of protein functions. Here we show that in multi-site systems like ion channels the application of the Hill formalism could require a combination of different ...
Interfacial effects on dielectric properties of ethylene propylene rubber–titania nano- and micro-composites
(Springer Verlag, 2015)
The influence of titania particle size on dielectric properties of ethylene–propylene rubber (EPR) composites was investigated, with an emphasis on the chain dynamics in the interphase region. We hypothesized that a reduction ...
Effect of different lead precursors on perovskite solar cell performance and stability
(Royal Society of Chemistry, 2014-12)
We present the use of halide (PbCl2) and non-halide lead precursors (Pb(OAc)2 (OAc = CH3CH2COO−), Pb(NO3)2, Pb(acac)2 (acac = (CH3COCHCOCH3)−) and PbCO3) for the preparation of perovskite solar cells. We have confirmed by ...
A high-capacity Li[Ni0.8Co0.06Mn0.14]O2 positive electrode with a dual concentration gradient for next-generation lithium-ion batteries
(Royal Society of Chemistry, 2015-09)
To increase the reversible capacity of layered lithium nickel-cobalt-manganese oxide, a Li[Ni0.8Co0.06Mn0.14]O2 positive electrode with a two-sloped full concentration gradient (TSFCG) was successfully synthesized via ...
Effects of CO2 activation of carbon aerogels leading to ultrahigh micro-meso porosity
(Elsevier, 2015)
We have analyzed the effects of CO2 activation on the porosity of ultrahigh pore volume carbon aerogels. Data obtained from the new 2D-NLDFT-HS model for carbons has been compared to the results of conventional methods ...
Dielectric relaxation dynamics of high-temperature piezoelectric polyimide copolymers
(Springer, 2015-08)
Polyimide copolymers have been prepared based on different diamines as comonomers: a diamine without CN groups and a novel synthesized diamine with two CN groups prepared by polycondensation reaction followed by thermal ...
