The impact of Förster resonant energy transfer (FRET) in CdTe quantum dot (QD) based photoelectrochemical cells is investigated. By deposition different QD sizes onto indium on oxide electrodes, FRET across the photoactive film could be obtained, resulting a 25% enhancement photon-to-current efficiency when compared to reference systems that lack FRET. Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or...
Abstract An alkoxy‐substituted poly(phenylene thiophene) is used in order to suspend single‐walled carbon nanotubes an organic solvent. The suspension spread on the air–water interface of a Langmuir trough and floating film characterized by means Brewster angle microscopy UV‐visible reflection spectroscopy compression isotherm recorded. polymer/carbon‐nanotube blend transferred onto different substrates using Langmuir–Blodgett technique. AFM measurements indicate formation globular...
Inorganic meets organic: Covalent bonds (peptide condensation) and noncovalent interactions (π–π stacking) have been employed en route toward versatile donor–acceptor inorganic–organic nanohybrids, QD-pyrene/SWNT. A charge-transfer event within the hybrid transforms excitonic state of quantum dot into a that has lifetime several nanoseconds. Detailed facts importance to specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset....
We have investigated the role of linker molecules in quantum-dot-sensitized solar cells (QDSSCs) using density-functional theory (DFT) and experiments. Linkers not only govern number attached QDs but also influence charge separation, recombination, transport. Understanding their behavior is therefore straightforward. DFT calculations show that mercaptopropionic acid (MPA) cysteine (Cys) exhibit characteristic binding configurations on TiO(2) surfaces. This information used to optimize cell...
PCE is improved owing to the enhanced <italic>J</italic><sub>SC</sub>, resulting from larger light harvesting and higher charge generation.
We present a series of non-stoichiometric cadmium sulfide quantum-dot (QD) models. Using density functional theory (DFT) and semi-empirical molecular orbital (MO) calculations, we explore the ligand binding exchange chemistry these Their surface morphology allows for processes to be rationalized on atomic scale. This is corroborated by ultraviolet–visible (UV–vis), infrared (IR), inductively coupled plasma–optical emission spectroscopy (ICP–OES).
The use of capacitively coupled contactless conductivity detection (C<sup>4</sup>D) for the characterisation thin conductive graphene fibres, composite and coated fibrous materials is demonstrated first time.
Point of care testing using micro-total-analysis systems (μTAS) is critical to emergent healthcare devices with rapid and robust responses. However, two major barriers the success this approach are prohibitive cost microchip fabrication poor sensitivity due small sample volumes in a microfluidic format. Here, we aimed replace complex format low-cost textile substrate inherently built microchannels fibers' spaces. Secondly, by integrating textile-based microfluidics electrophoresis wireless...
Using ultrasound, we provide a simple and rapid contactless approach for the mechanical characterization of photocrosslinked hydrogels with swelling properties.
This work presents a study on capacitively coupled contactless conductivity detector (C4D) for micron-sized fibers. Following previous report the qualitative application of C4D fibers, present provides thorough analysis signal response to fiber conductivity. Using reduced graphene oxide (RGO) as function length, cross-sectional area and resistance has been investigated. To effect insulating coatings, Parylene-coated RGO fibers were also In addition, measurements performed in different...
Anorganik trifft Organik: Kovalente (Peptid-Kondensation) und nichtkovalente Wechselwirkungen (π-π) wurden zur Herstellung von vielseitigen anorganisch-organischen Donor-Akzeptor-Nanohybriden, sprich QD-Pyren/SWNT, kombiniert. Ein Ladungstransfer innerhalb des Hybrids generiert aus dem excitonischen Quantenpunktzustand einen ladungsgetrennten Zustand, der für mehrere Nanosekunden stabil ist. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such...

Durch Oberflächenstabilisatoren an den QDs wird das kovalente Anbinden einer Pyrengruppe Verankern SWNTs erleichtert. Die komplementäre Analyse Lumineszenz Absorption ultraschneller Transienten spricht für die Bildung eines ladungsgetrennten Zustands. Damit ist Weg bereitet erfolgreiche...
