The authors applied two technologies to improve the efficiency of fluorescent blue organic light-emitting diodes (OLEDs). First, an efficiency-enhancement layer (EEL) was introduced to boost triplet-triplet fusion (TTF). Second, new blue dopants with a higher orientation factor in the emitting layer were developed. Consequently, the external quantum efficiency (EQE) was increased up to 11.5% wi...

Blue light induces sporulation of Physarum polycephalum macroplasmodia and reversibly inhibits spherulation (sclerotization) of microplasmodia. Illuminated microplasmodia have an abnormal appearance. The photobiological responses of the plasmodia appear to be unaffected by the absence of yellow pigment in the white mutant strain used. Illumination of microplasmodial suspensions with blue light ...

A new chromogenic plate medium, CHROMagar Orientation, was evaluated for use in the differentiation and presumptive identification of gram-negative bacilli and Enterococcus species by a multipoint inoculation (replicator) technique. In this study, 1,404 gram-negative bacilli and 74 enterococcal isolates were tested on CHROMagar Orientation. Six control American Type Culture Collection strains w...

Three deep-blue fluorescent 9,10-bis(4-tert-butylphenyl)phenanthrenes with diphenyl, -naphthyl, and -pyrenyl moieties at C3 and C6 positions were synthesized and used as the host for doped blue fluorescent devices; one of these devices reveals excellent external quantum efficiency of 7.7% and current efficiency of 9.8 cd A(-1) with low efficiency roll-off, deep-blue color coordinates (0.14, 0.1...

purpose: to report a case of butterfly-shaped macular dystrophy. patient and findings: a 34-year-old woman presented with metamorphopsia in both eyes from 2 years ago. visual acuity was 9/10 in right eye and 10/10 in left eye. there was no pathologic finding on slit lamp biomicroscopy and funduscopy other than mild macular retinal pigment epithelium mottling. visual fields and electroretinogram...

The neutral organic dye indigo forms an inorganic-organic hybrid material with nanoclays (see picture; blue circles on disks symbolizing indigo, spheres indicating liberated cations) and can thus be transferred into aqueous solution. Solids recovered from these solutions resemble the ancient Maya Blue pigment. The method can also be applied to other hydrophobic species and may open the gate for...

Minocycline is a commonly used antibiotic for long-term treatment of acne vulgaris. A well-documented and cosmetically dis-pleasing side effect is skin pigmentation. Three distinct types occur: Type I, blue-black/grey pigment on the face in areas of scarring or inflammation associated with acne; type II, blue-grey pigment on normal skin on the shins and forearms; type III, diffuse muddy-brown d...

BACKGROUND Nepalese population with Fitzpatrick skin types III-V has high prevalence of pigmentary disorders and it is a growing cosmetic concern. Q-Switched Neodymium- Doped Yttrium Aluminum Garnet (QS Nd-YAG) laser is an efficacious tool in the treatment of pigment disorders. OBJECTIVE To highlight the efficacy and safety profile of various pigment disorders. METHODS A prospective study d...
