energy that is radiated or transmitted in the form of rays or waves or particles
the act of spreading outward from a central source
a radial arrangement of nerve fibers connecting different parts of the brain
the spread of a group of organisms into new habitats
a column of light (as from a beacon) (同)beam of light, light beam, ray, ray of light, shaft, shaft of light, irradiation
a group of nearly parallel lines of electromagnetic radiation (同)ray, electron_beam
smile radiantly; express joy through ones facial expression
express with a beaming face or smile; "he beamed his approval"
(nautical) breadth amidships
long thick piece of wood or metal or concrete, etc., used in construction
the broad side of a ship; "they sighted land on the port beam"
send out rays or waves; "The sun radiates heat"
send out real or metaphoric rays; "She radiates happiness"
extend or spread outward from a center or focus or inward towards a center; "spokes radiate from the hub of the wheel"; "This plants radiate spines in all directions" (同)ray
cause to be seen by emitting light as if in rays; "The sun is radiating"
having rays or ray-like parts as in the flower heads of daisies
issue or emerge in rays or waves; "Heat radiated from the metal box"

Er(3+) doped Barium tellurofluoroborate glasses (BTFBxE) with the chemical composition (30-x)TeO2+30B2O3+20BaO+20BaF+xEr2O3 (where x=0.01, 0.05, 0.1, 0.5, 1.0 and 2.0 in wt%) were prepared following the melt quenching technique. The different vibrational modes of borates and tellurites in the prepar
The effects of glycerol on molecular mobility and hydrogen bonding network in an amorphous glassy starch matrix were studied using phosphorescence and IR spectroscopy. Amorphous potato starch films containing varying amounts of glycerol (0, 5, 10, 20 and 30wt.%) were formulated by rapidly dehydratin

Structural, spectroscopic and thermal properties of SiO₂-Al₂O₃-Sb₂O₃-Na₂O glass system doped with 0.2 mol% Tm₂O₃ have been presented. Synthesis of antimony-silicate glasses with relatively low phonon energy (600 cm(-1), which implicates a small non-radiative decay rate) was performed

The microphysical properties and processes of water (liquid-phase) clouds in the mid-latitudes were studied using space-borne radar and radiometer data, with a focus on comparisons between continental …
… Each radiative and nonradiative current components were separated from the total current by using the information of the internal quantum efficiency (IQE), obtained from the temperature-dependent electroluminescence measurement. …
Light emission characteristics of saw-like blue InGaN/GaN quantum well (QW) light-emitting diodes (LEDs) are theoretically investigated using the multiband effective mass theory. The saw-like QW struc …
Outside the core, the sun has a relatively quiet radiative zone. The radiative effects of water and clouds are at a maximum in this region. Changes in climate are drive by long-term changes in the sun's radiative output and magnetic ...
