Investigating the Effect of Reaction Time on Carbon Dot Formation, Structure, and Optical Properties
ACS Omega, 2019 Carbon dots, a young member of the carbon nanomaterial family, are quasi-spherical nanoparticles, which have fluorescent properties as their key characteristic. A wide range of starting materials and synthetic routes have been reported in the literature,

Strong defocusing of molecular reaction times results from an interplay of geometry and reaction control [PDF]
Commun. Chem. 1, 96 (2018), 2019 Text-book concepts of diffusion- versus kinetic-control are well-defined for reaction-kinetics involving macroscopic concentrations of diffusive reactants that are adequately described by rate-constants -- the inverse of the mean-first-passage-time to the reaction-event. In contradistinction, an open important question is whether the mean-first-passage-

Journal of Intelligence, 2016 Mean reaction times (RT) and the intra-subject variability of RT in simple RT tasks have been shown to predict higher-order cognitive abilities measured with psychometric intelligence tests.

Reaction extent or advancement of the reaction: A new general definition [PDF]
Chaos 33, Issue 4, Art. No. 043141 (2023), 2021 The concept of reaction extent (the progress of a reaction, advancement of the reaction, conversion, etc.) was introduced around 100 years ago. Most of the literature provides a definition for the exceptional case of a single reaction step or gives an implicit definition that cannot be made explicit. There are views that the reaction extent somehow has

Can we characterize A-P/IAP behavioural phenotypes in people with chronic pain?
Frontiers in Pain Research, 2023 Two behavioural phenotypes in healthy people have been delineated based on their intrinsic attention to pain (IAP) and whether their reaction times (RT) during a cognitively-demanding task are slower (P-type) or faster (A-type) during experimental pain ...

Effect of Age on Audio-Visual and Whole Body Reaction Time [PDF]
Al Ameen Journal of Medical Sciences, 2012 Objectives: With advancing age the incidence of falls and thereby morbidity goes on increasing. One important aspect of increase in the incidence of these mishaps may be the effect of age on reaction time.

Reaction Time Improvements by Neural Bistability
Behavioral Sciences, 2019 The often reported reduction of Reaction Time (RT) by Vision Training) is successfully replicated by 81 athletes across sports. This enabled us to achieve a mean reduction of RTs for athletes eye-hand coordination of more than 10%, with high statistical ...

eLife, 2021 The brain is capable of processing several streams of information that bear on different aspects of the same problem. Here, we address the problem of making two decisions about one object, by studying difficult perceptual decisions about the color and ...
