Thermonuclear burst oscillations

, 2012
Burst oscillations, a phenomenon observed in a significant fraction of Type I (thermonuclear) X-ray bursts, involve the development of highly asymmetric brightness patches in the burning surface layers of accreting neutron stars.

Mechanically Tunable Mechanochromic Device with Covert‐Overt Structural Color and Modulation of its Transparency

Advanced Materials Interfaces, EarlyView.
This study presents a novel mechanically responsive optical device that modulates light transmission and generates iridescent structural colors under reflection. The optical transition arises from the exposure of nanoparticles upon stretching, which are initially embedded beneath the surface.

Effect of Longitudinal Oscillations on Downward Flame Spread over Thin Solid Fuels [PDF]

Downward flame spread rates over vertically vibrated thin fuel samples are measured in air at one atmospheric pressure under normal gravity. Unlike flame spread against forcedconvective flows, the present results show that with increasing vibration ...

Charge Transfer States in Donor–Acceptor Bulk‐Heterojunctions as Triplet–Triplet Annihilation Sensitizer for Solid‐State Photon Upconversion

Advanced Materials Interfaces, EarlyView.
A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Flame Spread and Extinction over Electrical Wire Under Transverse Acoustic Waves

Fire
Acoustic fire suppression is a novel and environmentally friendly fire-extinguishing method. Electrical wires, as an important material in electrical systems, are a major cause of fires when short-circuited.

A review of wildland fire spread modelling, 1990-present, 1: Physical and quasi-physical models

, 2007
In recent years, advances in computational power and spatial data analysis (GIS, remote sensing, etc) have led to an increase in attempts to model the spread and behaviour of wildland fires across the landscape. This series of review papers endeavours to

Opposed-wind Effect on Flame Spread of Electric Wire in Sub-atmospheric Pressure

Journal of Thermal Science and Technology, 2008
Opposed flame spread of electric wire in sub-atmospheric pressure is studied experimentally. Thin-polyethylene (PE) coated nickel-chrome (NiCr) and iron (Fe) wire are used as test samples in this study. Total pressure is reduced from atmospheric (100 kPa)
