Quantifying soil ammonium and nitrite via soil gas emissions
Soil Science Society of America Journal, Volume 90, Issue 6, November/December 2026.Abstract Monitoring the soil mineral nitrogen (SMN) status of cropland is challenging due to large spatiotemporal variability. Here, we present a novel approach that correlates NH3, NO, and HONO emissions with SMN content, pH, and soil moisture, eliminating the need for destructive soil sampling. We conducted incubation experiments with five soils with

Advanced Science, Volume 13, Issue 56, 9 October 2026.Polydopamine nanoparticles enable a precise, non‐genetic, and transcranial neuromodulation strategy via near‐infrared photothermal stimulation. By activating TRPV1 channels, this approach specifically enhances hippocampal gamma oscillations, thereby rescuing spatial memory deficits in models of perioperative neurocognitive disorder.

Infrared photometry of the dust in comets
The Astronomical Journal, 1984 Infrared observations of six comets ranging in heliocentric distance from 1 to 5 AU are reported. Data consist of wide and intermediate bandpass filter photometry, 1-20 microns, for periodic comets Stephan-Oterma, Swift-Gehrels, Kearns-Kwee, Gunn, and Grigg-Skjellerup and for parabolic Comet Elias (1981 XV). All of the comets show infrared temperatures

Infrared Imaging and Photometry of a Sample of Seyfert Galaxies [PDF]
Symposium - International Astronomical Union, 1989 It is well know that the determination of the local luminosity function of Seyfert nuclei meets several difficulties produced by: the determination of a suitable sample, the estimation of the nuclear magnitudes biased from the contribution from the host galaxies, which may be dominant if the nucleus is faints and the presumably large errors associated ...

Ceres' Salty Ices: Sublimation‐Driven Evolution From Water Ice Exposures to Na‐Carbonate Deposits
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract The dwarf planet Ceres hosts nine geologically recent water ice exposures revealed by NASA's Dawn mission. We investigated the 0.04–11 km2 sites using visible imagery and infrared (1.0–4.3 μm) reflectance spectroscopy. Ice occurrence was mapped, and its abundance, grain size, and mixing mode with local regolith were constrained with Hapke ...

Visual and infrared photometry of asteroids
The Astronomical Journal, 1978 Results are reported for a survey of asteroids at 0.56, 1.6, and 2.2 microns. The observations of 30 asteroids are reduced to relative reflectances at 1.6 and 2.2 microns (such that the relative reflectance at 0.56 micron is scaled to unity). These relative reflectances have important implications for the classification of asteroids.
