Although carbon nanozymes have attracted great interest due to their good biocompatibility, low cost,and high stability, designing high-active carbon nanozymes still faces great challenges. Herein, ultrathin nitrogen-doped carbon nanosheets with rich defects(d-NC) were prepared through a high-temperature annealing process, using potassium chloride and ammonium chloride as templates. Owing to the large specific surface area, rich defects and the high exposure of active sites, the proposed d-NC nanozymes exhibited excellent peroxidase-like activity. The d-NC nanozymes possess maximal reaction velocity and their specific activity is 9.4-fold higher than that of nitrogen-doped carbon nanozymes, indicating that the induced defects can boost the catalytic performance. Benefited from the good peroxidase-like activities of d-NC nanozymes, the colorimetric sensing platforms were constructed for the detection of urease activity and fluoride ion, exhibiting satisfactory stability and selectivity. This study not only offers a way to synthesize carbon nanozymes with improved enzyme-like activities but also broadens their applications in colorimetric biosensing.

In this work, the Pd-based catalysts were designed via immobilizing Pd nanoparticles on graphite oxide (GO) modified with organic base, 1,1,3,3-tetramethylguanidine (TMG), which was used for the selective hydrogenation of citral. These catalysts were characterized by various techniques including IR, X-ray diffraction, transmission electron microscopy, and X-ray photoelectron spectroscopy. It was demonstrated that the Pd particles with size less than 5 nm were uniformly distributed throughout the support, and they were in the electron-deficient state due to the strong interactions with the modified support. The resultant Pd-TMG/GO catalyst displayed high efficiency for the selective hydrogenation of citral with a turnover frequency of 7100 h-1 as well as superior selectivity to citronellal of 89.6%. Moreover, the catalyst can be reused for five times without obvious activity loss, which may result from its stable structure.

目的重型颅脑创伤和重症高血压脑出血患者具备有创颅内压监测指征,探讨有创颅内压监测术后早期颅内感染发生率及危险因素。方法对226例重型颅脑创伤和重症高血压脑出血患者进行回顾性分析,按术中有无有创颅内压监测分为监测组和传统手术组(对照组)。观察术后1周内早期颅内感染的发生情况,并对感染危险因素进行分析。结果监测组45例患者中,颅脑创伤30例,高血压脑出血15例;对照组181例患者中,颅脑创伤96例,高血压脑出血85例。术后1周内,监测组颅内感染7例(15.56%),其中颅脑创伤4例(8.89%),高血压脑出血3例(6.67%);对照组颅内感染30例(16.57%),其中颅脑创伤15例(8.29%),高血压脑出血15例(8.29%)。2组比较,术后早期颅内感染发生率无统计学差异(P>0.05)。颅底骨折、术后营养指标、术后间断开放脑室型外引流管是监测组发生术后早期颅内感染的危险因素(P<0.05),而术后间断开放脑室型外引流管是独立危险因素(P<0.05)。结论术后1周内,在重型颅脑创伤和高血压脑出血患者中有创颅内压监测与传统手术比较不会增加颅内感染的风险,术后尽可能规避间断开放脑室型外引流管,可以在一定程度上防止有创颅内压监测术后早期颅内感染的发生。
