Cuprorivaite CaCuSi4O10, the so-called Egyptian blue pigment, exhibits a characteristic and well-known near-infrared luminescence upon excitation in Cu2+ d–d transitions. Here, we show that ex...

Article history: Received on: 06/04/2015 Revised on: 22/04/2015 Accepted on: 17/05/2015 Available online: 27/06/2015 Effect of culture conditions and critical medium components on antitubercular pigment production from novel Streptomyces sp D25 isolated from Thar desert, Rajasthan was investigated. Antitubercular pigment from Streptomyces sp. D25 was produced by Agar Surface Fermentation (ASF) ...

Bright blue CQD-loaded photopolymers synthesized via a one-step process, showing promise as fluorescent photocurable inks and coatings.

In acidic media, cationic phthalocyanine Alcian blue 8GX, has an efficient fluorescence quenching effect on anionic phthalocyanine tetrasulphoaluminium phthalocyanines (AlS₄Pc), forming an almost non-fluorescent associate. Based on this discovery, a red-emitting fluorescent probe consisted of AlS₄PC and Alcian blue 8GX has been developed through molecular assembly. Further studies indicated tha...

We present optical photometry and spectra of the peculiar type Ib supernova (SN) 2006jc. Strong He I emission lines indicate the progenitor star exploded inside a dense circumstellar medium (CSM) rich in He. An exceptionally blue continuum persists from our first spectrum obtained 15 days after discovery through our last spectrum ∼1 month later. Based on the presence of isolated Fe II emission ...

The bacterium, Acidovorax avenae ssp. avenae causes several important plant diseases including bacterial stripe of rice, bacterial stalk rot of corn, bacterial leaf blight of oats, and red stripe of sugarcane and millet. Although the organism is seed-borne in rice, no reliable seed assay is available. A semiselective liquid medium based on d-sorbitol and l-pyroglutamic acid (SP medium), and two...
