Inter‐Theta‐Gram Spectroscopy: A General Super‐Spectral‐Resolution Scattering Method Demonstrated on Diamond

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1359-1366, August 2026.
Inter‐Theta‐Gram spectroscopy enables super‐spectral‐resolution Raman analysis by jointly reconstructing the excitation laser line and Raman peak during an etalon angle scan, yielding internally referenced Raman shifts. Demonstrated on lab‐grown versus natural diamond, it resolves 0.1–0.2 cm−1 Raman‐shift offsets that are invisible in conventional ...

Radiobiology studies of gold nanoparticle‐enhanced radiosensitization in proton therapy

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Approximately 50%$\%$ of newly diagnosed cancer patients worldwide receive radiotherapy, most commonly with X‐rays. Proton therapy has emerged as a promising alternative, offering complementary advantages over conventional X‐rays due to its highly localized energy deposition at the Bragg peak, thereby reducing radiation exposure to ...

First‐Principle Analysis of the Structural, Elastic, Electronic, and Optical Properties of Novel AHgF3 (A = K and Fr) Perovskite

Nano Select, Volume 7, Issue 8, August 2026.
The evaluation of the physical properties of novel KHgF3 and FrHgF3 perovskites is explored. Both compounds are thermodynamically stable and mechanically ductile. Featuring narrow band gaps around 0.53–0.60 eV, these materials show strong potential for use in flexible infrared‐to‐visible optoelectronics and energy conversion devices.

Widespread Increase in Global Plant Water Stress Obscured by Greening

AGU Advances, Volume 7, Issue 4, August 2026.
Abstract Understanding the vulnerability of plants to more severe and frequent drought events and developing adaptive management strategies requires robust methods for quantifying long‐term changes in plant water stress (PWS). Most data‐driven explorations of long‐term trends in PWS have focused on alterations in canopy structure (e.g., leaf area index)

Cosmic Dust as a Prerequisite for the Formation of Complex Organic Molecules in Space?

The Astrophysical Journal
In cold, dense astrophysical environments dust grains are mixed with molecular ices. Chemistry in those dust/ice mixtures is determined by diffusion and reaction of molecules and radicals.

A laboratory astrophysics problem

, 2020
Emission lines of singly charged ions populate many astrophysical spectra. However, the interpretation of the line intensities (usually line ratios) often depends on the transition rates of the decays of very long-lived low-lying levels. For example, the line ratio of two electric-dipole forbidden transitions in the \(3s^{2} 3p^{3}\) ground ...

Can a Persistence‐Based Prediction of GRACE Gravity Field Coefficients Reduce Uncertainties at Finer Temporal Scales?

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Enhancing the applicability of Gravity Recovery and Climate Experiment (GRACE) products poses challenges due to the trade‐off between the temporal and the spatial resolution within limits posed by the mission design. If a Kalman filter framework was adopted to characterize the relationship between monthly and finer temporal scales, it could ...

Empirical Assessment of Storm‐Time Thermospheric Density Inversion Methods From LEO POD Data

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Thermospheric mass density is one of the largest sources of operational uncertainty for spacecraft in low Earth orbit, particularly during geomagnetic storms. The growing population of Global Navigation Satellite System‐equipped satellites presents a data set of opportunity: precise orbit determination (POD) data streams can be used to ...
