Coaxial D-dot probe: design and testing
Proceedings of 1995 Conference on Electrical Insulation and Dielectric Phenomena, 2002A new coaxial D-dot probe is designed and calibrated. A charge simulation programme is used to get the best configuration and arrangement of the probe design. The calibration is made against a conventional capacitive divider. The designed probe shows faster response and eliminates inductive overshoot to some extent.

Open quantum dots—probing the quantum to classical transition
Semiconductor Science and Technology, 2011Quantum dots provide a natural system in which to study both quantum and classical features of transport. As a closed testbed, they provide a natural system with a very rich set of eigenstates. When coupled to the environment through a pair of quantum point contacts, each of which passes several modes, the original quantum environment evolves into a ...

Ultrafast of-the-shelf V-DOT probes: Theory and experimentation
2015 IEEE International Conference on Plasma Sciences (ICOPS), 2015The present work is directly related to a repetitive 0.6 MV, 10 GW Tesla-driven Blumlein pulsed power generator, successfully developed at Loughborough University. In the second phase of the project, aiming at further compressing and modulating the output pulse using a bipolar pulse forming line system, multi-GHz diagnostic equipment is required to ...

Graphene Quantum Dots Probed by Scanning Tunneling Microscopy
Annalen der Physik, 2017AbstractScanning tunneling spectroscopy results probing the electronic properties of graphene quantum dots are reviewed. After a short summary of the study of squared wave functions of graphene quantum dots on metal substrates, we firstly present data where the Landau level gaps caused by a perpendicular magnetic field are used to electrostatically ...

Highly fluorescent magnetic quantum dot probe with superior colloidal stability
Nanoscale, 2010A magnetic quantum dot (MQD) based cellular nanoprobe, composed of a magnetic oxide nanoparticle component and a quantum dot component, has been synthesized and used for both imaging and separation. The successful synthesis is based on a reverse micelle based polyacrylate coating in the presence of component nanoparticles, followed by their ...

A self-assembled quantum dot probe for detecting β-lactamase activity
Biochemical and Biophysical Research Communications, 2006This communication describes a quantum dot probe that can be activated by a reporter enzyme, beta-lactamase. Our design is based on the principle of fluorescence resonance energy transfer (FRET). A biotinylated beta-lactamase substrate was labeled with a carbocyanine dye, Cy5, and immobilized on the surface of quantum dots through the binding of biotin

Attending to emotional expressions: no evidence for automatic capture in the dot-probe task
Cognition and Emotion, 2017Research on automatic attention to emotional faces offers mixed results. Therefore we examined validity effects for facial expressions of different emotions (compared to neutral faces) with a dot-probe paradigm in seven studies (total N = 308). Systematic variations of type of emotion, CTI, task, cue size, and masking allow for a differentiated ...

Attentional bias to pictures of fear-relevant animals in a dot probe task.
Emotion, 2005Attentional bias to fear-relevant animals was assessed in 69 participants not preselected on self-reported anxiety with the use of a dot probe task showing pictures of snakes, spiders, mushrooms, and flowers. Probes that replaced the fear-relevant stimuli (snakes and spiders) were found faster than probes that replaced the non-fear-relevant stimuli ...

A switchable fluorescent quantum dot probe based on aggregation/disaggregation mechanism
Chem. Commun., 2011Here we report a facile switchable fluorescent QD probe for F(-) ions, which is based on the hydrogen bonding-driven aggregation and the analyte-triggered disaggregation.

Calibration and Use of B Dot Probes for Electromagnetic Measuring
1977Abstract : Modern electromagnetic radiation testing techniques require accurately calibrated field probes that can operate over a wide range of frequencies, without adjustments. This requirement is an outgrowth of the use of wideband radio frequency amplifiers and computer-controlled swept frequency generators.
