Materials Processing,For an opaque solid, the fraction of incident radiation absorbed is . where . is the emissivity and .. is the reflectivity at normal incidence. .. and ∈ can be calculated from measurements of optical constants or the complex refractive index. For a complex refractive index, . the reflectivity at normal incidence is . The emissivity is then

Chemical Processing,The development of laser sources has revolutionized many aspects of photochemistry. The pace at which this revolution has progressed is remarkable: it is barely 12 years since the first laser photochemical experiments were carried out. The current literature extends to over a thousand articles.
