water content plays an important role in the process of plant photosynthesis and biomass accumulation. many methods have been developed to retrieve canopy leaf water content from remote sensing data. however, the validity of these methods has not been verified, which limits their applications. this study estimates the leaf water content (lwc) of winter wheat with three most widely used indexes:...

Single-layer graphene microislands with smooth edges and no visible grain boundary were epitaxially grown on the C-face of 4H-SiC and then characterized at the nanoscale using tip-enhanced Raman spectroscopy (TERS). Although these graphene islands appear highly homogeneous in micro-Raman imaging, TERS reveals the nanoscale strain variation caused by ridge nanostructures. A G' band position shif...

The nuclear region of the Seyfert galaxy NGC 1068 has been mapped in the near-infrared, from 1.25 to 2.23 µm, with the ESO adaptive optic system COME-ON+, at a spatial resolution of about 0.5. Imaging was carried out in the standard J, H, K spectral bands. In addition, simultaneous imaging in the near-infrared (K band) and in the visible (I band) was performed to accurately locate the emission ...

Digital camera sensors are sensitive to wavelengths ranging from the ultraviolet (200-400nm) to the near-infrared (700-100nm) bands. This range is, however, reduced because the aim of photographic cameras is to capture and reproduce the visible spectrum (400-700nm) only. Ultraviolet radiation is filtered out by the optical elements of the camera, while a specifically designed “hot-mirror” is pl...

We present high-resolution, near-infrared imaging of the circumnuclear region of the barred spiral galaxy M100 (=NGC 4321), accompanied by near-infrared spectroscopy. We identify a total of 43 distinct regions in the K-band image, and determine magnitudes and colours for 41 of them. By comparison with other near-infrared maps we also derive colour excesses and K-band extinctions for the knots. ...

Accuracy evaluation of cross calibration through band-to-band data comparison for visible and near infrared radiometers which onboard earth observation satellites is conducted. The conventional cross calibration for visible to near infrared radiometers onboard earth observation satellites is conducted through comparisons of band-to-band data of which spectral response functions are overlapped m...

We present the near–infrared H band luminosity function (hereafter LF) of the Coma cluster of galaxies. It is the deepest ever computed in the near–infrared, for any type of environment , extending over 7 magnitudes, down to ∼ M * H +6. The LF was computed on a near–infrared selected sample of galaxies whose photometry, complete down to the typical dwarf lumi-nosity, is presented in a companion...

We herein propose a proof of concept full dual-band electrochromic (EC) device able to selectively modulate solar light between 300 and 1600 nm. Dual-band control was achieved by exploiting the complementarity cooperation two earth-abundant nontoxic transition metal oxide nanocrystalline materials absorb different spectral regions when electrochemically charged. The active were obtained through...
