A search for particles of 550 me

Il Nuovo Cimento, 1958
In the experiment reported, mass determinations are essentially based on measurements of energy loss and range. The apparatus for detecting the particles is described. No 550 mass particles were observed in a time interval during which six could have been expected on the basis of their reported abundance.

Efficient Semipolar (11-22) 550 nm Yellow/Green InGaN Light-Emitting Diodes on Low Defect Density (11-22) GaN/Sapphire Templates.

ACS Applied Materials and Interfaces, 2017
We demonstrate efficient semipolar (11-22) 550 nm yellow/green InGaN light-emitting diodes (LEDs) with In0.03Ga0.97N barriers on low defect density (11-22) GaN/patterned sapphire templates. The In0.03Ga0.97N barriers were clearly identified, and no InGaN

Search for Mass-550 Particles

Physical Review Letters, 1958
The apparatus used in the search for cosmic-ray particles of mass ~550m/ sub e/ is described. It is concluded that the abundance of mass-550m/sub e/ particles which decay into a light meson is less than about 0.05% relative to mu mesons.

Destruction of C-550 by ultraviolet radiation

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971
Abstract Low-temperature absorption spectra of spinach chloroplasts measured after different periods of ultraviolet radiation show that C-550 is destroyed by the ultraviolent treatment. Cytochrome b559 is oxidized and denatured so that it is no longer reducible by ascorbate.

550 °C 4H-SiC p-i-n Photodiode Array With Two-Layer Metallization

IEEE Electron Device Letters, 2016
The p-i-n ultraviolet (UV) photodiodes based on 4H-SiC have been fabricated and characterized from room temperature (RT) to 550 °C. Due to bandgap narrowing at higher temperatures, the photocurrent of the photodiode increases by 9 times at 365 nm and ...

550. Tilia Endochrysea. Tiliaceae

Curtis's Botanical Magazine, 2006
Summary. Tilia endochrysea Hand.-Mazz. is native in mixed evergreen and deciduous broad-leaved woods in the mountains of south-eastern China. It differs from all other living species of Tilia in several characters which may be regarded as primitive.

Hyperspectral absorption coefficient of “pure” seawater in the range of 350–550 nm inverted from remote sensing reflectance

, 2015
Hyperspectral (every 5 nm) absorption coefficients of “pure” seawater in the range of 350–550 nm are derived from remote sensing reflectance measured in oligotrophic oceans. The absorption spectrum is reduced by ∼50–70% for the 350–400-nm range and ∼5–10%

Geochronology and geochemistry of the Dabure basalts, central Qiangtang, Tibet: evidence for ~550 Ma rifting of Gondwana

, 2015
Newly discovered basalts in the Dabure area (central Qiangtang block, northern Tibet) were subjected to laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U–Pb zircon dating, geochemical analyses, and zircon Hf isotope analyses ...
