The rate of volcanism on Venus [PDF]
The maintenance of the global H2SO4 clouds on Venus requires volcanism to replenish the atmospheric SO2 which is continually being removed from the atmosphere by reaction with calcium minerals on the surface of Venus. The first laboratory measurements of

Journal of Environmental Quality, EarlyView.Abstract Rapidly changing agricultural conditions need solutions to address complex decision‐making in an evolving socio‐ecological landscape. One way to accelerate the pace of solution development is by working directly with end users to design potential tools.

The symbol of the crescent Moon with a star on Ancient and Medieval coins [PDF]
Cultural Heritage and Modern TechnologiesThe individual phases of the moon show us this nocturnal satellite subjected to the laws of a cycle of dying and rising. In ancient times different peoples honoured the moon and the stars and felt connected to them in some way.

Journal of Raman Spectroscopy, EarlyView.Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals
Journal of Raman Spectroscopy, EarlyView.This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

A dynamic model of Venus's gravity field [PDF]
Unlike Earth, long wavelength gravity anomalies and topography correlate well on Venus. Venus's admittance curve from spherical harmonic degree 2 to 18 is inconsistent with either Airy or Pratt isostasy, but is consistent with dynamic support from mantle
