The development of lithium-sulfur(Li-s)batteries is hindered by the disadvantages of shuttling of polysulfides and the sluggish redox kinetics of the conversion of sulfur species during discharge and ***,the crystallinities of a titanium nitride(TiN)film on copper-embedded carbon nanofibers(Cu-CNFs)are regulated and the nanofibers are used as interlayers to resolve the aforementioned crucial issues.A low-crystalline TiN-coated Cu-CNF(L-TiN-Cu-CNF)interlayer is compared with its highly crystalline counterpart(H-TiN-Cu-CNFs).It is demonstrated that the L-TiN coating not only strengthens the chemical adsorption toward polysulfides but also greatly accelerates the electrochemical conversion of *** to robust carbon frameworks and enhanced kinetics,impressive highrate performance at 2 C(913 mAh g^(-1)based on sulfur)as well as remarkable cyclic stability up to 300 cycles(626 mAh g^(-1))with capacity retention of 46.5%is realized for L-TiN-Cu-CNF interlayer-configured Li-s *** under high loading(3.8 mg cm^(-2))of sulfur and relatively lean electrolyte(10μL electrolyte per milligram sulfur)conditions,the Li-s battery equipped with L-TiN-Cu-CNF interlayers delivers a high capacity of 1144 mAh g^(-1)with cathodic capacity of 4.25 mAh cm^(-2)at 0.1 C,providing a potential pathway toward the design of multifunctional interlayers for highly efficient Li-s batteries.

食品中完全无毒素的理念往往更接近于一种理想化的幻想而非现实。为辨别并优先处理长期摄入食品累积的有害物质,特别是天然毒素带来的健康风险,我们开展了一项针对性研究。通过审查100多项主要由欧洲食品安全局(EFsA)开展的欧洲层面的风险评估研究来评估食品供应的安全性。深入探讨了欧洲消费者长期接触的食品中潜在天然毒素对健康的影响,以及关于特定毒素的研究发现。此外,尝试对长期接触与公众健康有关的食品化学污染物所构成的风险进行排名。黄曲霉毒素被列为食品中第三大重要的化学污染物,因其具有很强的致癌能力,会导致人类患肝癌,加之欧洲谷物类食品消费量高,导致了高风险。虽然吡啶碱类物质具有基因毒性和致癌性,但由于人类接触这类植物毒素的来源有限——例如通过茶、蜂蜜或草药,它们在榜单中仅排第五。

真菌毒素是某些真菌菌种在特定条件下产生的有毒次级代谢产物。研究发现多种真菌毒素的联合暴露可引起胎儿发育迟缓、胚胎停育甚至流产等胚胎发育毒性。目前,尚没有关于孕期真菌毒素暴露对宫内胎儿胚胎发育毒性的影响和生物监测情况的系统报道。因此,为预防和降低孕期真菌毒素暴露带来的危害,本文梳理了孕期传统真菌毒素如黄曲霉毒素、脱氧雪腐镰刀菌烯醇、玉米赤霉烯酮和新兴真菌毒素如交链孢毒素、白僵菌素和恩镰孢菌素等暴露引起的胚胎发育毒性,以及以生物标志物如暴露标志物和效应标志物为基础的生物监测技术的研究现状。

strong>Background:strong> Fixation of bone flap following craniotomy is usually achieved by synthetic materials. In rural and poor funding areas, innovation for cheap, safe and applicable material is needed. strong>Purpose:strong> The aim is to assess our new innovative technique in bone flap fixation against traditional techniques. strong>Patients and Methods:strong> The study was a prospective randomized controlled study enrolled at Al-Amal Hospital and Al-Ahly Bank Hospital from 2014-2019. Forty-eight patients were randomized in the study. Group A (24 patients) underwent titanium miniplate fixation while group B (24 patients) underwent our new technique. The new technique is double J tunnels performed by craniotome on either side of the bone (flap and skull sides), then a Prolene suture is passed through the shared stem of J’ holes and secured in the wrapped side of J’s holes and tying it tightly. Both techniques were examined against fixation time, rigidity, offset and final judgment postoperatively. strong>Result:strong> There was no statistically significant difference in using both techniques as regard fixation time. Our new technique was not inferior to the traditional one in achieving rigidity (p > 0.05). The final postoperative assessment was as equal as that seen in miniplate fixation. strong>Conclusion: strong>This technique is a simple, easy, cheap and effective method of fixing craniotomy bone flap.
