Ultrastructural observation in hamster and rat lungs after chronic inhalation of cadmium compounds

, 2022
S.264-268Long-term inhalation of CdCl2 at concentrations as low as 12.6 myg Cd/cbm causes development of lung tumors in rats (4). No information, however, was available on the chronic carcinogenicity of CdO, CdS and CdSO4 which are especially relevant to

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,
