Integrating Water-Soluble Polythiophene with Transition-Metal Dichalcogenides for Managing Photoinduced Processes
Published in ACS Applied Materials & Interfaces
Transition-metal dichalcogenides (TMDs) attract increased attention for the development of donor–acceptor materials enabling improved light harvesting and optoelectronic applications. The development of novel donor–acceptor nanoensembles consisting of poly(3-thiophene sodium acetate) and ammonium functionalized MoS2 and WS2 was accomplished, while ...

(Pb 0.97 La 0.02)(Zr x Sn 0.94−x Ti 0.06)O 3 (PLZST) antiferroelectric ceramics with x = 0.75−0.90 have been fabricated and found to be a novel electrocaloric material system with a giant negative electrocaloric effect (ΔT = −11.5 K) and a large electrocaloric strength (|ΔT/ΔE| = 0.105 K cm kV −1) near room temperature. Additionally, the PLZST anti...
Self-Assembled Core–Shell CdTe/Poly(3-hexylthiophene) Nanoensembles as Novel Donor–Acceptor Light-Harvesting Systems
Published in ACS Applied Materials & Interfaces
The self-assembly of novel core–shell nanoensembles consisting of regioregular poly(3-hexylthiophene) nanoparticles (P3HTNPs) of 100 nm as core and semiconducting CdTe quantum dots (CdTeQDs) as shell with a thickness of a few tens of nanometers was accomplished by employing a reprecipitation approach. The structure, morphology, and composition of C...
Flexible Photodiodes Based on Nitride Core/Shell p-n Junction Nanowires
...
A flexible nitride p-n photodiode is demonstrated. The device consists of a composite nanowire/polymer membrane trans- ferred onto a flexible substrate. The active element for light sensing is a vertical array of core/shell p−n junction nanowires containing InGaN/ GaN quantum wells grown by MOVPE. Electron/hole generation and transport in core/shel...

Photovoltaic property of a vertically aligned carbon nanotube hexagonal network assembled with CdS quantum dots.
Published in ACS Applied Materials & Interfaces
A vertically aligned carbon nanotube (VACNT) hexagonal network was fabricated by plasma enhanced chemical vapor deposition as an electrode scaffold to assemble CdS quantum dots (QDs). The quantum dot sensitized solar cell (QDSSC) based on a VACNT/CdS hexagonal network shows a short circuit current density of 4.7 mA/cm(2), which is almost twice of t...
Highly efficient red-emitting hybrid polymer light-emitting diodes via Förster resonance energy transfer based on homoge...
Published in ACS Applied Materials & Interfaces
Highly efficient inverted-type red-emitting hybrid polymeric light-emitting diodes (HyPLEDs) were successfully demonstrated via Förster resonance energy transfer (FRET) and interfacial engineering of metal oxide with a cationic conjugated polyelectrolyte (CPE). Similarly structured green- and red-emissive polyfluorene copolymers, F8BT and F8TBT, we...
Hybrid polymer-silicon proton conducting membranes via a pore-filling surface-initiated polymerization approach.
Published in ACS Applied Materials & Interfaces
An alternative approach for the creation of proton conducting platforms is presented. The methodology is based on the so-called "pore-filling concept", which relies on the filling of porous matrices with polyelectrolytes to obtain proton conducting platforms with high dimensional stability. Polymer-silicon composite membranes, with well-defined pol...
