To investigate structure-property relationship of polymer-based curcumin solid dispersion (SD), three acrylic polymers were used to formulate curcumin SD by solvent evaporation method. Curcumin ...

Results from multiple randomized clinical trials comparing outcomes after intravascular ultrasound (IVUS)– and optical coherence tomography (OCT)–guided percutaneous coronary intervention (PCI) with ...

Fluorescent molecules that absorb and emit light in the near-infrared (NIR) and short-wave infrared (SWIR) regions have ...

Nagpur: A spectacular halo formed around the Sun on Wednesday afternoon, creating a lot of curiosity among citizens and ...

Laser frequency combs are light sources that produce evenly spaced, sharp lines across the spectrum, resembling the teeth of ...

We're putting these big astronomy binos to the test for lunar viewing, stargazing and observing deep-sky objects.

Abstract: The influence of the nonlinear refractive index and the group-velocity dispersion of optical fibers on optical-amplifier noise is studied. A new method is used to calculate the spectrum of ...

Our today’s optical illusion is all set to put your observation skills to the test. The goal is to find the number “24” that’s different from the rest — but you only have five seconds to do it. While ...
