对于具有高压轨迹的微电子设备,可在真空环境中起作用,重要的是要知道真正的损坏电压对压力的影响以避免发生故障。Paschen定律在压力和距离变化时是众所周知的崩溃电压行为方程。它的常见数学表达[1]是在两个平行导电板的均匀字段假设下写的。最近有一些作品,其中一些特殊导体配置的不均匀的电晶体以及在真空中的PCB痕迹考虑的,压力高达10 -1 mbar [2]。也有关于均匀场,非常低的距离(10 UM及更近)和低真空的帕申曲线行为异常的报告[3,4]。在这里,我们介绍了对一种不均匀领域的paschen效应的研究,这是针对一种常见的PCB痕量构造的,距离距离为100 um,低真空度最高为10 -4 TORR。在本文的第2节中,我们提供了简化的理论估计,该理论估计使用Townsend标准对最小崩溃电压。在第3节中,描述了测量压力的崩溃电压依赖性的实验设置,并在第4节中提出了真空相机中PCB迹线的实验研究结果。
Abstract: Information located in an entanglement island in semiclassical gravity can be nonperturbatively reconstructed from distant radiation, implying a radical breakdown of effective field theory. We show that this occurs well outside of the black hole stretched horizon. We compute the island associated to large-angular momentum Hawking modes of a four- dimensional Schwarzschild black hole. These modes typically fall back into the black hole but can be extracted to infinity by relativistic strings or, more abstractly, by asymptotic boundary operators constructed using the timelike tube theorem. Remarkably, we find that their island can protrude a distance of order p ℓ p r hor outside the horizon. This is parametrically larger than the Planck scale ℓ p and is comparable to the Bohr radius for supermassive black holes. Therefore, in principle, a distant observer can determine experimentally whether the black hole information paradox is resolved by complementarity, or by a firewall.
Controlling microstructure in fusion-based metal additive manufacturing (AM) remains a challenge due to numerous parameters directly impacting solidification conditions. Multiprincipal element alloys (MPEAs) offer a vast compositional design space for microstructural engineering due to their chemical complexity and exceptional properties. Here, we establish a novel alloy design paradigm in MPEAs for AM using the FeMnCoCr system. By exploiting the decreasing phase stability with increasing Mn content, we achieve notable grain refinement and breakdown of columnar grain growth. We combine thermodynamic modeling, operando synchrotron X-ray diffraction, multiscale microstructural characterization, and mechanical testing to gain insight into the solidification physics and its ramifications on the resulting microstructure. This work paves way for tailoring grain sizes through targeted manipulation of phase stability, thereby advancing microstructure control in AM.
要找出蛋白质在转化过程中扮演的角色,研究人员设计了番茄植物来开关和关闭生产,使他们能够看到他们的影响。他们发现了一种叫做DML2的,该DML2在关闭产量时阻止了糖基类动物的分解,使水果太苦了,无法吃。进一步的研究表明,该蛋白质能够通过称为脱甲基化的化学过程分解糖基虫类。
