Prof. von Jolly’s 1878 prediction of the end of theoretical physics as reported by Max Planck
(2016-03-06)
It is provided here the original German and an English translation of a passage from a 1924 essay by Max Planck that reports a prediction of the end of theoretical physics expressed to him by one of his esteemed physics ...
Monte Carlo investigations of the effect of beam divergence on thick, segmented crystalline scintillators for radiotherapy imaging
(2010-07)
The use of thick, segmented scintillators in electronic portal imagers offers the potential for significant improvement in x-ray detection efficiency compared to conventional phosphor screens. Such improvement substantially ...
Plasmonic backscattering enhanced inverted photovoltaics

Melanin-Containing Films: Growth from Dopamine Solutions versus Layer-by-Layer Deposition
(WILEY-VCH Verlag, 2010-10-25)
Films formed by oxidation of dopamine are of interest for functionalisation of solid–liquid interfaces owing to their versatility. However, the ability to modulate the properties of such films, for example, permeability ...
The Disk-wind-Jet Connection in the Black Hole H 1743-322
(IOP Publishing, 2012)
X-ray disk winds are detected in spectrally soft, disk-dominated phases of stellar-mass black hole outbursts. In contrast, compact, steady, relativistic jets are detected in spectrally hard states that are dominated by ...
The Projected Halo Model.
(2013)
I present a semi-analytical halo model to study line-of-sight projection effects in the galaxy cluster population. The model produces realizations of sight-lines using halo space densities and two-halo correlations, and ...
Time-Resolved Studies and Nanostructure Formation in Sb2Te3 Films Using Femtosecond Lasers.
(2014)
Antimony telluride (Sb2Te3) is an important material with a wide range of applications in thermoelectrics, data storage devices and topological insulator research. Our work on femtosecond laser studies of Sb2Te3 films has ...
Towards Molecular Control and Rational Design of Molecules with Enhanced Entangled Two-Photon Absorption.
(2015)
We utilize entangled photons to carry out nonlinear optical spectroscopy in organic molecules with an extremely small number of photons. While much research has been devoted to utilizing quantum mechanics and quantum ...
X-Ray Spectral Variability in NGC 3783
(IOP Publishing, 2012)
NGC 3783 was observed for approximately 210 ks by Suzaku and in this time showed significant spectral and flux variability at both short (20 ks) and long (100 ks) timescales. The full observation is found to consist of ...
Electromagnetic Transmission Through Resonant Structures.
(2016)
Electromagnetic resonators store energy in the form of oscillatory electric and magnetic fields and gradually exchange that energy by coupling with their environment. This coupling process can have profound effects on the ...
