Sentences with phrase «optical absorption»

Some black phosphorus characteristics, such as the onset of optical absorption, were nearly unaffected in the calculations.

This is what the ESRL had to say about satellite - based COs sensing and I quote «Greenhouse gas abundances derived from optical absorption measurements from space can never be calibrated because one can not control the abundance of the gases being estimated, nor can we control potential interfering factors in the optical path.»

(For experts, the red arrow represents Raman spectroscopy, the black arrow represents synchrotron x-ray diffraction, and the gray arrow represents optical absorption spectroscopy.)

«Due to the higher hemoglobin concentration, abnormal angiogenesis has higher optical absorptions in certain wavelengths than normal tissues,» Xiao explained.

Statistical results also show that the mean optical absorption (MOA) of the cervical lesions is closely related to the severity of cervical cancer.

«MX2 semiconductors have extremely strong optical absorption properties and compared with organic photovoltaic materials, have a crystalline structure and better electrical transport properties,» Wang says.

Photoinduced optical absorption studies demonstrate a different excitation spectrum for the composite as compared to the separate components, consistent with photo - excited charge transfer.

The second part is a polymer with optical absorption controllable by an electrochemical potential.

In a method patented by two of the article's authors, often referred to as Feng and Holonyak's idea, the optical absorption can be further enhanced by the cavity coherent photon intensity of the transistor laser.

Therefore, the optical absorption distribution can be obtained deep in the biological tissue.

By processing all of the photoacoustic imaging data with computer programs, scientists obtain a 2 - D en - face photoacoustic image called a depth maximum amplitude projection (DMAP) image, which shows the optical absorption distribution or photoacoustic contrast of the sample.

They discovered that the threshold of the optical absorption spectrum is due to a strongly bound exciton, which exhibits two remarkable novel properties: First, it is confined on a two - dimensional (2D) plane of the three - dimensional lattice of the material.

But others, such as the band gap and shape of the optical absorption changed dramatically, so the properties of the material become qualitatively different.

The PYP microcrystals were perfectly matched to the optical absorption so that the entire crystal was undergoing dynamics, which in turn allows sensitive measurements of the molecular changes by snapshot X-ray diffraction.

Then, computational simulations based on quantum mechanics — in particular, Time - Dependent Density Functional Theory, which plays a key role in studying optical properties in theoretical condensed matter physics — are tapped to calculate the optical absorption spectrum of chromophores in cellulose.

Once reflectance data is gathered, the optical absorption spectrum of cellulose fibers that form the sheet of paper can be calculated using special spectroscopic data analysis.
