Synthesis of Ce-Doped ZIF-8-Derived Core–Shell ZnO Sensors via Double Sintering for Highly Sensitive Formaldehyde Detection at Room Temperature 来源：ACS PublicationsFormaldehyde, a common indoor air pollutant, poses a serious threat to human health. Therefore, there is an urgent need to develop highly selective and sensitive formaldehyde gas sensors that operate at room temperature. Doping with rare-earth elements is an effectively proven strategy for optimizing the gas-sensing performance at room temperature. This study developed a method to modify ZnO derived from ZIF-8 by doping it with the ...

来源：ACS PublicationsHafnium oxide (HfO2) is considered as the most promising candidate for replacement of conventional SiO2 in complementary metal-oxide semiconductor (CMOS) technology. Owing to the appropriate high dielectric constant (k) of HfO2 with excellent thermodynamic stability against silicon, it is capable of mitigating the major hurdle of high leakage current density encountered in the present CMOS industry. HfO2 primarily exhibits three distinct phases such as monoclinic phase having k ∼ 15 stable at room temperature (RT) and tetragonal (k ∼ 70) and cubic phases (k ∼ 30) observed at...

Interface Reconstruction Induced by Rare-Earth Incorporation Stabilizes High-Coordination Cu+ Sites for Efficient Electrochemical Nitrate Reduction to Ammonia 来源：ACS PublicationsThe electrochemical nitrate reduction reaction (eNO3–RR) represents a promising route for simultaneous wastewater treatment and sustainable ammonia synthesis. While Cu2O catalysts featuring electron-deficient Cu+ sites have been widely studied for eNO3–RR, their practical implementation is hindered by self-reduction and structural instability. Constructing Cu–O–M interfacial sites, which enhance charge transfer and sta...

Hybrid Solvation Model for Analyzing the Binding of Yttrium and Calcium Cations to the Lanmodulin Protein Using the Fragment Molecular Orbital Method 来源：ACS PublicationsA hybrid solvation model combining microsolvation with continuum solvent is proposed to analyze the binding of calcium and yttrium cations to the lanmodulin protein (PDB: 6MI5), using the fragment molecular orbital method combined with partition analysis. The contributions of protein deformation, metal ion desolvation, and the formation of a water cluster from desolvated metal ions, as well as protein–ion and water-ion interact...
