Hercules Street and Hercules Place were two of Belfast’s oldest streets and, by the mid-nineteenth century, they were in the town centre. These streets always had a large concentration of butchers (a cluster). This cluster was broken up in 1880 whe

Electrical breakdown was induced in a vacuum directly across a crack. These breakdown events are explained in terms of fracto-emission (the emission of charged particles, neutral species and photons due to fracture) serving as a trigger which induced

The emission of electrons and positive ions from materials undergoing fracture is investigated. We present a survey of charged particle emission from a number of materials including crystalline insulators, glass, graphite, polymers and composites. Pa

Hydrogen adsorbs on the (100) face of niobium at 90 K into three states sequentially. The first state, which appears to be molecular, has a dipole moment of −0.022 Debye/molecule, an initial sticking coefficient of 0.23, and a saturation coverage o

The effects of an electron beam on ammonia adsorption and desorption on Ru(0001) have been investigated by Auger electron spectroscopy, low-energy electron diffraction, and thermal flash desorption. Appreciable adsorption at room temperature occurred

We have examined ejecta (particles in the size range 0.1 to 500 μm) which are released by fracture of a variety of materials. The ejecta from most non-metallic materials are electrically charged and frequently have high velocities. The amount of eje

The adsorption of ammonia, hydrogen, and nitrogen on a Ru(0001) surface have been investigated by Auger electron spectroscopy, low-energy electron diffraction, and thermal flash desorption. The adsorption of ammonia on Ru(0001) can be divided into a

It is well known that visible light is emitted during the peeling of adhesives from various substrates. The major source of light has been identified as small gaseous discharges that result from the intense charge separation accompanying detachment o

Tribostimulated exoelectron emission provides a sensitive way to characterize anodic films on aluminium. This paper describes the detection of acoustic emission (AE) and electron emission (EE) during the tensile deformation of anodized aluminum. It i

During separation in air of an adhesive from a polymer substrate we have observed intense bursts of photons (phE for photon emission) and long wavelength electromagnetic radiation (RE-for radiowave emission), similar to those reported earlier by Dery
