10+ hour, 29+ min ago  (411+ words) The study utilizes a combination of electron microscopy, optical techniques, and conventional bulk characterization tools. Thin sections of processed PLLA were prepared by ultramicrotomy and subjected to 4 D-STEM, which collects nanobeam electron diffraction (NBED) patterns at each scan position. Moreover,…...

4+ mon, 4+ day ago  (967+ words) Research conducted over the last decade has transformed tip-enhanced Raman scattering (TERS) from a technique once widely regarded as "niche" to a popular and routine nanoscale characterization method. 1 TERS continues to see widespread and beneficial use in the analysis of…...

2+ mon, 2+ day ago  (713+ words) Analytical chemistry is a methodical field of study in which different types of electromagnetic radiation are directed at molecules to observe how they respond. Each selected region of the spectrum, such as ultraviolet, near-infrared, or focused laser light, elicits distinct…...

2+ mon, 1+ week ago  (242+ words) Researchers from Nanyang Technological University, Singapore (NTU Singapore) have found a new way to produce X-rays with wavelengths in what is called the "water window. This new method holds promise in making bioimaging X-ray machines smaller and more flexible to…...

3+ mon, 1+ week ago  (125+ words) Astronomers have detected extended X-ray emission from JADES-ID1 at z5. 68, confirming the presence of a hot intracluster medium just one billion years after the Big Bang. The finding provides the earliest direct evidence that massive halos were already undergoing virial heating…...

4+ mon, 1+ week ago  (392+ words) Researchers at Cold Spring Harbor Laboratory have developed a new mass spectrometry method, enhancing instrument performance to provide more sensitive scans. This advancement could improve drug target identification and assist scientists in addressing persistent questions about human health and biology....
