ChemPhysChem, Volume 26, Issue 8, April 14, 2025.Chemical exchange saturation transfer (CEST) with different spin exchange kinetics can require substantial RF energy deposition to label magnetization in separate chemical environments. The parameter space with optimum saturation should be judged not only concerning unwanted heating but also consider efficient CEST build‐up (depolarization rate ...

Comparing introductory physics and astronomy students' attitudes and approaches to problem solving [PDF]
Euro. J. Phys. 39 065702 (2018), 2019 We examined how introductory physics students' attitudes and approaches to problem solving compare to those of introductory astronomy students, using a previously validated survey, the Attitudes and Approaches to Problem Solving (AAPS) survey. In addition, we compared the performance of the introductory physics and astronomy students on the factors ...

Advanced Materials Technologies, Volume 10, Issue 8, April 17, 2025.This work explores the thermal kinetics of laser‐zone‐drawn electrospun nanofibers. Laser‐zone drawing is a technique that allows for localized heating of nanofiber segments, which results in better mechanical drawing. The high surface‐to‐volume ratio of nanofibers allows for ultrafast thermal kinetics at small diameters.

Using Data Science in High School Astronomy [PDF]
arXivAstronomy datasets can be challenging to use for high school astronomy classes. Data science education pedagogy can be leveraged to create astronomy activities in which students interrogate data, create visuals, and use statistical thinking to construct astronomy knowledge.

Advanced Optical Materials, Volume 13, Issue 11, April 14, 2025.One of the high‐impact research goals in neuromorphic photonics is to build scalable photonic artificial intelligence computing at high energy efficiency. This perspective paper discusses microring resonator (MRR)‐based large‐scale photonic neural networks, variations of MRR resonance wavelength from fabrication, and post‐fabrication processing with ...

Neutrino astronomy and gamma-ray bursts
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007 The construction of large-volume detectors of high energy, greater than 1 TeV, neutrinos is mainly driven by the search for extragalactic neutrino sources. The existence of such sources is implied by the observations of ultra-high-energy, greater than or equal to 10 19 eV, cosmic rays, the origin of which is a ...

Earth Surface Processes and Landforms, Volume 50, Issue 5, April 2025.This transdisciplinary study analyses the geomorphic consequences of microbial mats associated with freshwater outflows in a macrotidal environment. Microorganisms were identified using the DNA metabarcoding approach. SEM analysis of quartz collected from the beach surface provided data on the marine and aeolian forces, as well as biological processes ...
