钛合金具有极高的强度重量比,可用于多种关键的支持技术。然而,它们在严酷环境中的使用面临着其有限的抗高温氧化性能的挑战。为了解决这个问题,本研究采用金属有机化学气相沉积 (MOCVD) 方法在 Ti6242S 合金表面涂覆致密的非晶态氧化铝 AlzO 3 涂层,涂层成分包括三丙醇铝 ATI 和二甲基铝异丙醇 (DMAI)。等温氧化试验表明,与裸露材料相比,涂层 Ti6242S 试样的质量增益抛物线速率常数降低了两个数量级。DMAI Al 2 O 3 涂层合金在 600 °C 下经过 5000 小时的长时间氧化,重量增加 0.180 mg cm-2,而裸露合金的重量增加 1.143 mg cm-2。在这些条件下,会形成一个界面层,其中包含复杂的 TiiAlo 5 Sn 0 .5)(或 (Ti,Sn)zN) 相。在 50 至 600 °C 之间进行 80 次 1 小时循环氧化,结果显示涂层样品的质量增益为零。最后,在氧化试样的横截面上确定的硬度分布表明涂层合金的氧溶解非常有限。非晶态 AlzO 3 的 MOCVD 涂层具有巨大潜力,可有效、持久地防止 Ti6242S 合金氧化。
欧盟最近禁止使用氯苯胺灵 (CIPC)(委员会实施条例 (EU) 2019/989),这促使马铃薯加工行业寻找替代且更安全的抗发芽方法。低温(即 4°C)储存已成为在不使用 CIPC 的情况下长期储存马铃薯的有效选择。然而,大多数商业马铃薯品种在冷藏过程中会积累高水平的还原糖 (RS),这种现象称为冷诱导甜化 (CIS)。在将马铃薯高温加工成薯片和炸薯条等产品的过程中,RS 会与天冬酰胺和肽发生反应生成神经毒素丙烯酰胺,加工产品会呈现棕色至黑色(Bhaskar 等人,2010 年)。图 1a 以图形方式描述了马铃薯储存的挑战。由于培育抗 CIS 的马铃薯品种来取代易感 CIS 的品种十分困难,新基因组技术 (NGT) 正成为一种有用的方法,可快速将抗 CIS 特性引入加工行业使用的商业品种中。尽管基于 CRISPR 的方法可以灵活地针对植物基因组中的任何选定序列,但迄今为止,该技术主要用于针对植物中的蛋白质编码序列。在本研究中,我们利用编辑 5' UTR 序列来改造业界首选的马铃薯品种的 CIS 抗性。液泡转化酶 (VInv) 已被确定为将蔗糖转化为 RS 的关键酶。先前的研究表明,沉默 VInv 基因是降低马铃薯冷藏后 RS 积累的一种合适方法 (Bhaskar 等人,2010 年;Zhu 等人,2016 年)。
摘要。对 5754、6061 和 7075 铝合金进行了 RCS 工艺提高机械强度的潜力评估,这三种铝合金呈现出与各自合金元素相关的不同硬化机制。这项工作比较了不同合金通过 RCS 处理后织构和机械性能的演变。通过显微硬度测量、不同温度和应变速率下的拉伸试验来评估机械性能,以评估应变速率敏感性。结果表明,经过两次 RCS 处理后,6061 和 5754 合金在 300°C 下表现出相对较高的应变速率敏感性。此外,5754、6061 和 7075 合金的硬度分别增加了 27%、22%、15%。显示出由于不同的硬化机制而提高机械阻力的潜力。此外,通过 X 射线衍射获得极图并计算其取向分布函数来表征晶体织构。结果表明,三种铝合金表现出相同的趋势,即初始织构组分得以保留,但织构化体积有所减少。
有机太阳能电池(OSC)的功率转化效率超过20%,这是形态优化起着重要作用的进步。普遍认为,加工溶剂(或溶剂混合物)可以帮助优化形态,从而影响OSC效率。在这里,我们开发了对一系列加工溶剂的强大耐受性的OSC,所有设备的高功率转换效率均约为19%。通过研究溶液状态,膜的形成动力学以及经过实验和计算的处理膜的特征,我们确定控制形态的关键因素,即受体材料的侧链与溶剂链的侧链以及供体和受体材料之间的相互作用之间的相互作用。我们的工作为形态控制的长期问题和有效指南提供了新的理解,以将OSC材料设计用于实用应用,在这种应用中,大规模加工需要绿色溶剂。

对于CRISPR/CAS工作流程,核酸酶和相应GRNA的选择直接影响基因组编辑后的indel频率的计算。当前用于评估编辑效率的当前METH OD使用来自转染的细胞的合并GDNA的PCR扩增,然后是基于测序或基于测序的基于测序或基于不匹配的裂解的分析分析的变性和重新启动的indneal indneal indneal DNA(4)。为加快编辑效率的确定并避免昂贵的NG测序,“通过分解来跟踪Indels”(Tide)(5)和“ CRISPR编辑的推断”(ICE)方法(6)是开发用于使用sanger sequenc dna sequenceenc dna dna dna dna dna dna dna dna dna dna dna dna dna dna(ice)方法(ICE)方法(ICE)方法(ICE)。但是,要使这些方法可靠,分析的PCR产品必须具有高质量(例如,单个频带,没有底漆和DNTP)。在本文中,我们证明了通过Exo-CIP快速PCR清洁套件方法清理的扩增子质量匹配,该方法是通过使用ICE软件工具进行批处理分析的传统基于旋转柱的套件来实现的,从而启用了更快,更高的推出方法,以制备旋转后的样品,用于旋转后的样品。
