Article Synopsis
- Peptides, specifically the gallium-binding peptide HGaBP, were used as effective adsorbents for recovering gallium when immobilized in sodium alginate (SA), resulting in microspheres with an impressive adsorption capacity of 127.4 mg/g.
- The study demonstrated that these microspheres are highly selective for gallium at lower pH levels and follow the pseudo-second-order kinetic model and Langmuir isotherm model for adsorption.
- Detailed analyses, including molecular docking and various spectroscopic techniques, revealed that gallium ions are initially attracted through electrostatic interactions and then undergo cation exchange and coordination, enhancing the thermal stability of the adsorbent and offering a more environmentally friendly solution for gallium recovery compared to traditional
Article Synopsis
- A novel tapered fiber-optic radiation sensor (TFRS) using cerium and terbium co-doped YAG scintillation crystals has been successfully developed, showcasing effective integration into silica glass cladding.
- The TFRS exhibits low optical fiber loss (0.14 dB/cm), significantly better than the YAG crystal's loss (1.59 dB/cm), allowing efficient light coupling.
- It demonstrates strong luminescence under various excitations with a response to γ-rays that is four times higher than standard plastic scintillation fiber sensors, indicating its potential for precise and stable remote radiation detection.
