静电相互作用对纤维蛋白质原在金表面吸附的影响及牛血清蛋白质与胶原蛋白质竞争吸附的AFM研究
, 2002 固体表面的性质对蛋白质的吸附具有很大的影响作用,蛋白质在固体表面的吸附可分为共价吸附和非共价吸附.非共价吸附主要包括氢键、疏水力和静电力三种相互作用.其中静电相互作用对蛋白质吸附的影响仍未有一致的看法.该文将椭偏显微成像系统与电化学方法联用来研究静电相互作用在蛋白质吸附中的影响.在0.1MKHPO-NaHPO(pH=7.80)溶液中,金膜表面零电荷电势(PZC)在-0.60V(vs.SCE)左右.开路电位为+0.10V(vs.SCE),大于零电荷电势(PZC),说明金膜表面带正电荷 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Lithium‐rich manganese‐based cathodes (LRM) deliver high discharge capacities beyond 250 mAh g−1, but their practical deployment is restricted by irreversible oxygen redox, structural reconstruction, sluggish kinetics and unstable cathode‐electrolyte interfaces (CEI). Here, we develop a colloid‐assisted anchoring‐diffusion engineering strategy

Bidirectional Interfacial Chemical Regulation Enables Durable Aqueous Zn‐I2 Batteries
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐I2 batteries hold great promise for large‐scale energy storage, yet their practical deployment is hindered by coupled interfacial instabilities at both electrodes, where Zn‐anode parasitic reactions and cathodic polyiodide shuttle mutually aggravate each other.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The central challenge in photocatalysis is to direct photogenerated electrons and holes toward the simultaneous and efficient production of hydrogen and value‐added chemicals. To address the pronounced charge recombination and sluggish surface kinetics of ZnIn2S4 nanoflowers, we construct a ternary photocatalyst synergistically decorated with ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Photocatalytic acetylene (C2H2) semihydrogenation is a green route for ethylene (C2H4) production, yet the activity–selectivity trade‐off caused by imbalanced adsorption/activation of reactants and products remains a core challenge. Herein, we realize precise regulation of Pd oxidation states (Pd0, Pdδ+, and Pd2+) on anatase TiO2 nanocubes via

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Electrochemical carbon dioxide reduction reaction (CO2RR) powered by renewable electricity offers a sustainable route for producing value‐added carbonaceous chemicals. Herein, a three‐membrane electrolyzer was employed to directly co‐generate carbon monoxide (CO), chlorine (Cl2), and potassium carbonate (K2CO3) from the electrolysis of CO2 and

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Electrosynthesis of hydrogen peroxide (H2O2) via the two‐electron oxygen reduction reaction (2e−ORR) offers a sustainable and decentralized alternative to the anthraquinone process. However, conventional solo‐active‐site catalysts are intrinsically limited by scaling relationships, imposing a trade‐off between activity and selectivity.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Tin‐based composite oxides typically undergo severe volume variations and exhibit poor intrinsic conductivities despite their high theoretical capacity as promising anode candidates for sodium‐ion batteries. This results in rapid structural degradation and capacity fading upon cycling.
