Introduction Ultraviolet (UV) photodetectors have attracted considerable attention recently due to their applications in optical communication, medical, military, astronomical study, chemical/biological sensing and flame detection [1] and the possibility to be able to detect visible light upon tuning with the external voltage is a very appealing perspective [2-6].Bismuth oxyhalide compounds BiOX (X = Cl, Br, and I) evoked great interest recently due to their good photocatalytic activity under UV or visible light illumination, unique layered structure, high activity, and high photocorrosion stability.[7-13] The layered structure of BiOX [14] can provide the space large enough to polarize the related atoms and orbitals.[15] The induced dipole can separate the electron−hole pair efficiently, enhancing photocatalytic activity. [16] Therefore, BiOBr is a promising material for detecting light radiation due to its high absorption coefficient and high stability.

This paper proposes the use of the quantum pair formation for generating a working mass, this is different than conventional anti-matter thrusters since the material particles generated are used as a propellant mass not as energy storage.

Due to the prevailing conditions inside, the hearth of the blast furnace is made up of graphite, carbon, carbon-graphite, and microporous materials.
It implies a requirement for adequate quality of refractory materials applied, and as a consequence maintenance costs of such big units necessitate the extension of the life of the furnace.
Charge materials with titanium compounds have started being used in order to extend the life of the refractory lining and the service life of the blast furnace.
