2014年7月15日 · A simple method for the synthesis of water-soluble carbon quantum dots (CQDs) has been developed based on chemical oxidation of starch. The structures and optical properties of the CQDs were characterized by ultraviolet–visible (UV–Vis) spectroscopy, photoluminescence spectroscopy (PL) and transmission electron microscopy.

2023年2月15日 · Pandora’s Cluster (Abell 2744) Astronomers estimate 50 000 sources of near-infrared light are represented in this image from the NASA/ESA/CSA James Webb Space Telescope. Their light has travelled through various distances to reach the telescope’s detectors, representing the vastness of space in a single image.

ALT has acquired the deepest NIRCam grism spectroscopy yet (7-27 hr), at JWST's most sensitive wavelengths (3-4 $\mu$m), covering the powerful lensing cluster Abell 2744. Over the same 30 arcmin$^2$, ALT's ultra-deep F070W+F090W imaging ($\sim$30 mag) enables selection of very faint sources at $z>6$.

The Ideal 45-2744-1 is a special blade designed for the Raytheon MIL-spec 55. Die-type blades allow for precision stripping, and the counterbored holes sizes and inner stripping hole size are designed to meet tough MIL-specs. This blade is manufactured for accuracy and precision to meet your specific applications.

Here we will show you how to convert 2744 pixels to inches. First, note that pixels can be abbreviated to px, which means that 2744 pixels to inches is the same as 2744 px to inches. For our calculations, a pixel is a dot, and we assume that the pixel density is 96 dots per inch (dpi).

DTC U2744, sometimes indicated as U274400 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle user network.
