Electrochemical and quantum chemical approaches to the study of dopamine sensing using bentonite and l-cysteine modified carbon paste electrode.

This work presents a significant investigation involving both electrochemical experiment and quantum chemical simulation approaches. The objective was to characterize the electrochemical detection of dopamine (DA). The detection was carried out using a modified carbon paste electrode (CPE) incorporating bentonite (Bent) and l-cysteine (CySH) (named as CySH/Bent/CPE).

Acousto-optically driven lensless single-shot ultrafast optical imaging.

Driven by many applications in a wide span of scientific fields, a myriad of advanced ultrafast imaging techniques have emerged in the last decade, featuring record-high imaging speeds above a trillion-frame-per-second with long sequence depths. Although bringing remarkable insights into various ultrafast phenomena, their application out of a laboratory environment is however limited in most cases, either by the cost, complexity of the operation or by heavy data processing. We then report a versatile single-shot imaging technique combining sequentially timed all-optical mapping photography (STAMP) with acousto-optics programmable dispersive filtering (AOPDF) and digital in-line holography (DIH).

Patient motivation in group metacognitive therapy for generalized anxiety disorder.

Objective: The aim of this study was to investigate the predictive value of motivational language (change talk [CT] and sustain talk [ST]) on treatment outcome of group metacognitive therapy (g-MCT) for generalized anxiety disorder (GAD).

Method: Video recordings of the first, fourth, and seventh therapy sessions (55 patients) were encoded using the Motivational Interviewing Skill Code (MISC) manual. The strength of the patients' motivational utterances was encoded as CT or ST with seven subcategories.

-Poly[[bis-(quinolin-8-amine-κ ,')cadmium(II)]-μ-cyanido-κ :-[dicyanidonickel(II)]-μ-cyanido-κ :].

In the title compound, [CdNi(CHN)(CN)] , the Cd and Ni atoms both lie on centres of inversion in space group 2/. The Cd atom is coordinated by two bidentate quinolin-8-amine ligands and by the N atoms of two cyano ligands, while the square planar Ni atom is coordinated by the C atoms of four cyano ligands. These units form a one-dimensional coordination polymer containing an (-NC-Ni-CN-Cd-) backbone, and the coordination polymer chains are linked into a three-dimensional array by a combination of N-H⋯N and C-H⋯N hydrogen bonds, augmented by a π-π stacking inter-action.

High-energy normal-dispersion fiber optical parametric chirped-pulse oscillator.

We demonstrate a fiber optical parametric chirped-pulse oscillator (FOPCPO) pumped in the normal-dispersion regime by chirped pulses at 1.036 µm. Highly chirped idler pulses tunable from 1210 nm to 1270 nm with energies higher than 250 nJ are generated from our system, along with signal pulses tunable from 870 nm to 910 nm.
