Terahertz time-domain spectroscopy of edible oils [PDF]

open access: yesRoyal Society Open Science, 2017
Chemical degradation of edible oils has been studied using conventional spectroscopic methods spanning the spectrum from ultraviolet to mid-IR. However, the possibility of morphological changes of oil molecules that can be detected at terahertz ...

Photon-photon and photon-hadron processes in Pythia 8 [PDF]

open access: yesCERN Proc, 2017
We present a new implementation of photoproduction processes in e+e- and ep collisions into Pythia 8 Monte-Carlo event-generator. In particular we discuss how the parton showers and multiparton interactions are generated with a resolved photon beam and what is the relative contribution from direct processes in different kinematical regions.

Mid-infrared quantum optics in silicon

open access: yes, 2020
Applied quantum optics stands to revolutionise many aspects of information technology, provided performance can be maintained when scaled up. Silicon quantum photonics satisfies the scaling requirements of miniaturisation and manufacturability, but at 1 ...

Trans‐Conductive Melt Pool Scaling and its Implications for Parameter Transfer in Laser Powder Bed Fusion for Metals with High Thermal Diffusivity

open access: yesAdvanced Engineering Materials, EarlyView.
Developing process parameters for the laser‐based Powder Bed Fusion of metals can be a tedious task. Based on melt pool depth, the process parameters are transferable to different laser scan speeds. For this, understanding the melt pool scaling behavior is essential, particularly for materials with high thermal diffusivity, as a change in scaling ...

The operational characteristics and potential applications of a low voltage EMCCD in a CMOS process [PDF]

open access: yes, 2018
The Electron Multiplying Test Chip 1 (EMTC1) was developed with the aim of creating a device which could produce superior Electron Multiplication (EM) gain at a greatly reduced voltage. An EM gain exceeding 3% per stage has been recorded for a relatively
