Bacterial infection arised from multipathogenic bacteria is a tricky issue that attracts worldwide attentions.In this paper,a highly accessible copper single-atom catalyst (Cu SAC) supported by biocompatible N-doped mesoporous carbon nanospheres was synthesized with the emulsion-template method.The tightly anchored copper single-atom of the catalyst could effectively transform O2 into O2-· under ambient conditions by the ultra-large pore size (~ 23.80 nm) and small particle size (~ 97.71 nm).Due to multiple synergistically oxidative damages to biomolecules,the Cu SAC could be employed to eliminate different bacteria in vitro without the generation of multidrug resistance (MDR).Moreover,the Cu SAC could also promote wound healing in vivo by eradicating the propagation of bacteria at wound.It is envisioned that the Cu SAC with superior antibacterial penformance could be applied in the treatment of related bacterial infection in future.

基于黄河河口、现代黄河三角洲、黄河入海流路三者在概念定义上的异同,划定了黄河入海流路地貌单元分类研究的范围.在系统总结河口地貌研究现状的基础上,运用一般地貌学原理、“形态-成因”原则和等级系统原则,综合比较入海流路各地貌单元的存在形式、主要生成原因、发育规模和范围、以及对流路演变的影响权重.将整个流路系统视为Ⅰ级地貌,形成了包括河道、海岸、水下三角洲等三个Ⅱ级地貌,堤防、河槽、汊河、拦门沙、滩涂等16个Ⅲ级地貌的黄河入海流路的地貌分类系统.进一步构建了沟汊、滩涂、拦门沙等典型地貌单元类型的分类谱系.结合黄
The development of efficient and stable electrocatalysts with earth-abundant elements for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in the same electrolyte is incontrovertibly vital in water electrolysis.However,their larg
河口潮汐流是典型的非均匀、非恒定和周期性的水体运动.在研究潮流挟沙力问题中,利用水流对泥沙输移的有效剪力方法,即从总剪力中提取水流对泥沙颗粒的有效部分,可以排除非均匀、非恒定和形体阻力等影响.首先说明了有效剪力法计算潮流挟沙力的步骤,然后选用1994-2018年10个典型河口的实测潮流泥沙资料,对潮流挟沙力计算的有效剪力法、能量法、极值法和经验法进行了对比检验.结果 表明,有效剪力法具有较高的计算精度和较强的实用性.此外,利用有效剪力法的潮流挟沙力公式进行计算,无需实测资料率定且普适性好,便于在无资料或缺
Graphene nanoribbons (GNRs) have potential for applications in electronic devices.A key issue,thereby,is the fine-tuning of their electronic characteristics,which can be achieved through subtle structural modifications.These are not limited to the convent
Surfaces can significantly alter the optical properties of nanomaterials,but they are difficult to control and their roles are hard to understand in highly reactive materials such as silicon nanomaterials.In this work,we investigate the role of the surfac
The practical application of lithium-sulfur (Li-S) batteries is hampered by the insulative nature of sulfur,sluggish electrochemical kinetics,and large volume variation,which result in capacity-fading at a large current density and poor cycling stability.
The growth regularities of nanomaterials are often concealed by the contingency of preparation.Therefore,it is always very difficult to figure out growth regularities of nanomaterials due to the accompanying undulation of products.A series of precise synt
