Recycling of Post-Consumer Polystyrene Packaging Waste into New Food Packaging Applications—Part 1: Direct Food Contact

open access: yesRecycling, 2023
The increase in plastic recycling is an essential pre-requisite for the transition to a circular economy. Polystyrene (PS) is a low diffusive polymer and therefore a promising candidate for recycling back into food contact similar to polyethylene ...

Time-resolved detection of single-electron interference [PDF]

open access: yes, 2008
We demonstrate real-time detection of self-interfering electrons in a double quantum dot embedded in an Aharonov-Bohm interferometer, with visibility approaching unity.

Construction of perovskite solar cells using inorganic hole-extracting components [PDF]

open access: yes, 2018
A NiOx−graphene oxide (NiOx−GO) hybrid has been prepared by a simple solution-processed method and was used as hole-extraction material in perovskite solar cells with either gold or carbon as back contact electrode.

Contact Force Reconstruction from the Lower-Back Accelerations during Walking on Vibrating Surfaces

open access: yesVibration, 2021
Current models describing the effect of crowd-induced loading require a full-scale validation. To measure the lower-back accelerations during such validation, low-cost accelerometers are used to ensure a sufficient scalability.

Aluminum–Titanium Alloy Back Contact Reducing Production Cost of Silicon Thin-Film Solar Cells

open access: yesEnergies, 2016
In this study, metal films are fabricated by using an in-line reactive direct current magnetron sputtering system. The aluminum–titanium (AlTi) back contacts are prepared by changing the pressure from 10 mTorr to 25 mTorr.

Quantum interference and phonon-mediated back-action in lateral quantum dot circuits

open access: yes, 2012
Spin qubits have been successfully realized in electrostatically defined, lateral few-electron quantum dot circuits. Qubit readout typically involves spin to charge information conversion, followed by a charge measurement made using a nearby biased ...

Effects of microwave irradiation on the parameters of hydrogel contact lenses [PDF]

open access: yes, 2003
Ten brands of hydrogel contact lenses were selected from five of the six British Approved Name lens classification groups to test in vitro the effects of repeated heat disinfection by means of microwave irradiation.

The clinical back pain courses described by information available in Danish central registries

open access: yesBMC Health Services Research, 2022
Background Patients with back pain are often in contact with 2–4 hospital departments when receiving a back pain diagnosis and treatment. This complicates the entire clinical course description.
