Advanced Functional Materials, Volume 34, Issue 45, November 5, 2024.Infusion withdrawal coating allows impregnation of cellulose with various FeCl3 concentrations. Carbonization leads then to gradual changes in the carbon microstructure and transport properties. This results in an exciting material with a controllable temperature gradient. Abstract Carbon materials comprise a wide range of microstructures and excellent

Distributions of non‐native and native plants are not determined by the same environmental factors
Ecological Solutions and Evidence, Volume 5, Issue 4, October–December 2024.Distributions of non‐native plant species are driven more strongly by anthropogenic variables than distributions of native plant species, though climate is the most powerful predictor in both species groups. Species distribution models should therefore be fitted with different variables based on the study species' degree of nativeness.

Yankuang ceshi, 2014 High purity titanium and titanium alloy have good plasticity, but with the presence of impurity, their performance will become brittle and hard. The accurate quantitative analysis of impurity elements is useful for carrying on the quality control of ...

Quarterly Journal of the Royal Meteorological Society, Volume 150, Issue 765, Page 4671-4708, October 2024 Part B.Research shows that 100‐m scale models can improve the representation of several meteorological phenomena. Here, improved resolution of either the atmosphere or the surface is important for modelling urban hazards. This review article surveys the challenges in transitioning these models into practical forecast systems and suggests ways forward.

Design of a mid-IR immersion echelle grating spectrograph for remote sensing [PDF]
, 1995 We describe the design of a silicon immersion grating spectrograph for the remote detection of chemicals in the atmosphere. The instrument is designed to operate in the two atmospheric windows from 2.3 to 2.5 and 2.8 and 4.2 microns at a resolution of 0 ...

Journal of Geophysical Research: Planets, Volume 129, Issue 8, August 2024.Abstract Detecting trace gases such as hydrogen chloride (HCl) in Mars' atmosphere is among the primary objectives of the ExoMars Trace Gas Orbiter (TGO) mission. Terrestrially, HCl is closely associated with active volcanic activity, so its detection on Mars was expected to point to some form of active magmatism/outgassing.
