Heliotropic dust rings for Earth climate engineering [PDF]
, 2013 This paper examines the concept of a Sun-pointing elliptical Earth ring comprised of dust grains to offset global warming. A new family of non-Keplerian periodic orbits, under the effects of solar radiation pressure and the Earth's J(2) oblateness ...

Orbital dynamics of "smart dust" devices with solar radiation pressure and drag [PDF]
, 2011 This paper investigates how perturbations due to asymmetric solar radiation pressure, in the presence of Earth shadow, and atmospheric drag can be balanced to obtain long-lived Earth centred orbits for swarms of micro-scale 'smart dust' devices, without ...

An investigation into the role of time-dependent cohesion in interseismic fault restrengthening
Scientific Reports, 2019 Earthquakes typically exhibit recurrence times that far exceed time-scales attainable in a laboratory setting. To traverse the temporal gap between the laboratory and nature, the slide-hold-slide test is commonly employed as a laboratory analogue for the

T1–T2 microscale correlation relaxometry for in situ high-pressure nuclear magnetic resonance [PDF]
Matter and Radiation at ExtremesOver the last decade, frequency-domain in situ high-pressure nuclear magnetic resonance (NMR) spectroscopy in diamond anvil cells (DACs) has been employed as a structural and electronic probe of condensed matter systems at pressures well into the megabar

Using dimers to measure biosignatures and atmospheric pressure for terrestrial exoplanets [PDF]
, 2014 We present a new method to probe atmospheric pressure on Earth-like planets using (O-O) dimers in the near-infrared. We also show that dimer features could be the most readily detectable biosignatures for Earth-like atmospheres and may even be detectable

Thermodynamic Properties of MgAl2O4 Spinel at High Temperatures and High Pressures
Crystals, 2023 Thermodynamic properties of MgAl2O4 spinel are significant in understanding the phase relations of the Earth’s crust and upper mantle, but available values from experimental measurements are limited at ambient pressure conditions to date.

Passive Earth Pressure in Narrow Cohesive-Frictional Backfills
, 2023 A narrow backfill zone is formed when retaining walls are built near existing stabilized structures (e.g., rock faces). In such circumstances, the classical passive earth pressure coefficient is no longer applicable, and a correction factor is required ...

A passive satellite deorbiting strategy for medium Earth orbit using solar radiation pressure and the J(2) effect [PDF]
, 2012 The growing population of space debris poses a serious risk to the future of space flight. To effectively manage the increase of debris in orbit, end-of life disposal has become a key requirement for future missions.
