Extremely High Electron Mobility in GeSn Epitaxial Films by Chemical Vapor Deposition

open access: yesAdvanced Electronic Materials, Volume 11, Issue 11, July 2025.
Transport properties in n‐GeSn films are investigated. By applying tensile stress or increasing the Sn fraction, electron mobility is significantly enhanced since more electrons populate the Γ‐valley, where the electron effective mass is small. A remarkably high electron Hall mobility of 6,200 cm2V−1s−1 is achieved in the strained‐relaxed n‐Ge0.88Sn0 ...

Human bare and clothing-covered skin exposure to chlorinated paraffins for the general populations: Exposure pattern differential and significance of indirect dermal exposure via clothing-to-skin transport

open access: yesEnvironment International
To investigate human exposure to short-chain chlorinated paraffins (SCCPs) and medium-chain chlorinated paraffins (MCCPs) through dermal and oral intake via hand-to-mouth contact, wipes from the face, forearm, hand, and foot of 30 volunteers were sampled.

Epitaxial AIN/AIN bimorph piezocantilevers for geothermal monitoring [PDF]

open access: yesE3S Web of Conferences
The problem of early and reliable prediction of earthquakes, which can lead to catastrophic consequences, is far from being solved, so it remains extremely topical. The next step towards its solution, as it is supposed, could be the creation of a network

From Spirocyclic Germanium Alkoxides to their Fluorido Germanates

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 18, June 24, 2025.
Spirocyclic germanium salicyl alcoholates potentially meet the requirement as molecular precursors for twin polymerization, which is defined as a concerted formation of two polymeric materials from a so‐called twin monomer. Two examples of such germanium alkoxides and their associated fluorido germanates are reported and aspects of their chirality and ...

Interannual variability and spatial diversification of global urban tree cooling effects

open access: yesEnvironment International
While widespread urban greening is documented, how these efforts translate into changes in a city’s cooling potential remains unanswered. Here, we employed multi-satellite observations to assess the spatial dynamics and temporal variations in tree ...
