  • Antibacterial metals and alloys for potential

    2021-2-8 · Zn-based alloys have been turned focus towards an ideal degradation materials (such as cardiovascular stents) taking account of their moderate degradation rate in comparison with the fast biodegradation rate of Mg and Mg alloys and the low biodegradation rate of Fe-based materials due to different standard potentials of Mg, Zn and Fe (−2.372 V, −0.762 V and −0.440 V, respectively) . …

  • Effects of Water-Collecting and -Retaining Techniques

    2012-7-1 · The experimental results showed that water-collecting and -retaining techniques can effectively increase soil moisture content, the leaf photosynthetic rate and crop growth. Due to increased soil moisture under the plastic-covered ridge and furrow water-collecting in July and August, dry matter and plant height had a increase at the booting stage (late growth advantage).
