In recent years, the mixed halide Perovskite Solar Cells (PSCs) triggered huge amount of R&D activities, thanks to their excellent optoelectronic properties, fast progressing power conversion efficiencies and low cost potential. On top of that, with their high specific power & compatibility with flexible substrate, PSCs appear as a promising mid/lo...

MicroLink Devices manufactures triple-junction inverted metamorphic solar cells on GaAs wafers with a selectively etched release layer in an epitaxial lift-off (ELO) process to create ultra-thin foils of semiconductor with a metal backing. To improve radiation tolerance, each absorber layer is thinned and doping levels are reduced. The bottom subce...

Space debris are composed of both natural and human made objects, some in near Earth orbits while others are passing through deep space. Asteroids may represent one form of near Earth and deep space debris. In this article we report on a set of asteroid observations from the southern hemisphere. We indicate that Apollo and Aten class asteroids repr...
To better extract the tides represented in the European meteorological analysis ERA5, an analysis of the histograms of the diurnal and semi-diurnal modes as a function of longitudes was performed. This analysis revealed that modes with different characteristics appeared regionally along a single longitude. Retrieved migrating tides were compared wi...

Introduction: During manned space exploration lung health is threatened by toxic planetary dust and radiation. Thus, tests such as lung diffusing capacity (DL) are likely be used in planetary habitats to monitor lung health. During a DL maneuver the rate of uptake of an inspired blood-soluble gas such as nitric oxide (NO) is determined (DLNO). The ...

This article suggests a conceptual framework for choice of target populations for public health interventions. In short, who should benefit? Taking the seminal work of Geoffrey Rose on “individuals at risk” versus the “whole population approach” as a point of departure, we explore later contributions. Frohlich and Potvin introduced the notion of “v...

Models of solar and space plasmas require an accurate model for thermal transport. The simplest such model is to assume that the fluid approach is valid and that local transport models can be used. These local transport coefficients are derived under the assumption that the electron mean-free path is “small” compared to the temperature scale length...

Long duration space exploration is no longer a fantasy, with Elon Musk claiming to launch astronauts to Mars as early as 2029. The substantial increase in spaceflight duration required for a Mars mission has resulted in a stronger focus on behavioural health outcomes at NASA, with increased interest in using virtual reality countermeasures to both ...
Peer reviewed: True / A “Space Renaissance” is underway. As our efforts to understand, utilize and settle space rapidly take new form, three distinct human-space interfaces are emerging, defined here as the “Earth-for-space,” “space-for-Earth” and “space-for-space” economies. Each engenders unprecedented opportunities, and artificial intelligence (...

The article attends to everyday practices in a laboratory of neural genetics that studies olfaction, with the fruit fly as its model organism. Practices in neural genetics exhibit one of the 'post' aspects in post-genomic science - a turn to the environment. To get at how laboratory members engage body-environment continuities, I pay attention to a...
