Thioflavin-T (ThT) is one of the most commonly used dyes for amyloid detection, but origin its fluorescence enhancement not fully understood. Herein we have characterised ThT response upon binding to Aβ(1-40) and Aβ(1-42) variants Alzheimer's-related peptide amyloid-β, in order explore how photophysical properties this dye relates structural morphological two fibril types formed by peptides with a high degree sequence homology. We show that steady-state 1.7 times more intense compared...
Covalently linking a Re catalyst to CuInS<sub>2</sub> QDs through facile click reaction for efficient electron transfer improve photocatalytic CO<sub>2</sub> reduction is reported.
Achieving long-range charge transport in molecular systems is interesting to foresee applications of molecules practical devices. However, designing with pre-defined wire-like properties remains difficult due the lack understanding mechanism for transfer. Here we investigate a series porphyrin oligomer-bridged donor-acceptor Fc-Pn-C60 (n = 1-4, 6). In these triads, excitation porphyrin-based bridge generates fully charge-separated state, Fc(•+)-Pn-C60(•-), through sequence electron transfer...
Co-sensitization of molecular dyes and catalysts on semiconductor surfaces is a promising strategy to build photoelectrodes for solar fuel production.
Conjugated zinc porphyrin oligomers of various lengths are shown to form well-defined planar aggregates at low temperatures. The aggregation occurs over a narrow temperature interval (170–150 K) and is accompanied by dramatic changes in the electronic absorption emission spectra. Similar found J-aggregates which transition dipole moments aggregated chromophores couple new intense spectrum, red shifted from monomeric chromophore band. For present oligomers, not associated with formation large...
The rate of the photoinduced charge-separation in C60-terminated butadiyne-linked porphyrin oligomers Pn (n = 4, 6) is strongly influenced by their molecular conformation. In these systems, presence butadiyne linkers gives rise to a broad distribution conformations ground state, due an almost barrierless rotation individual units oligomer chain. conformational states oligomers, either twisted or planar, could be selected varying excitation wavelength, thereby providing different initial...
A laser-induced breakdown spectrometry (LIBS) system for rapid slag analysis near a steel process has been tested and evaluated.
A series of highly fluorescent conjugated anthracene dendrimers having monomeric emission profile, but still exhibiting fast exciton depolarisation, are here presented.
This work is focused on rapid quantitative analysis of slag in the steel industry for improved process control. The novel approach this a direct comparison two methods to calibrate and quantify spectral data from slags. Calibration was first done with most prevalent method optical emission spectroscopy (OES) solids, univariate ratio method. second an advanced multivariate (MVA) algorithm termed Elastic Net, allowing include several lines each element calibration functions. In both methods,...
Abstract Laser‐induced breakdown spectroscopy (LIBS) is an atomic‐emission technique that enables rapid chemical analysis of a wide range materials, including metals, semiconductors, glasses, biological tissues, plastics, soils, thin and paint coatings. The relies on focusing short high‐energy laser pulses onto the surface target sample, which in turn generates plasma containing small amount sample (typically, few nanograms).
