Twisting monolayers of graphene with respect to each other has led to a number of unusual correlated states. This approach has inspired researchers to try their hand at twisting two-dimensional magnets， but such experiments have proven a difficult challenge. Song et al. made structures out of layers of the 2D magnet chromium triiodide with a small twist angle . Using nitrogen vacancy centers in diamond as a magnetometer， the authors imaged the magnetic domains in both twisted monolayer and twisted trilayer structures. For twisted trilayers， a periodic pattern of ferromagnetic and antiferromagnetic domains was revealed.

Thermoelectric materials allow for direct conversion between heat and electricity， offering the potential for power generation. The average dimensionless figure of merit ZTave determines device efficiency. N-type tin selenide crystals exhibit outstanding three-dimensional charge and two-dimensional phonon transport along the out-of-plane direction， contributing to a high maximum figure of merit Zmax of ~3.6 × 10−3 per kelvin but a moderate ZTave of ~1.1. We found an attractive high Zmax of ~4.1 × 10−3 per kelvin at 748 kelvin and a ZTave of ~1.7 at 300 to 773 kelvin in chlorine-doped and lead-alloyed tin selenide crystals by phonon-electron decoupling. The chlorine-induced low deformation potential improved the carrier mobility. The lead-induced mass and strain fluctuations reduced the lattice thermal conductivity. Phonon-electron decoupling plays a critical role to achieve high-performance thermoelectrics.

红警磁爆线圈是特斯拉的发明？今天聊聊能炸天的无线输电
【太平洋汽车网 技术频道】众所周知，修行尚浅的老僧无法“隔衣疗伤”，传授内力更是只能通过肌肤接触的方式传功。与武侠世界中相似的是，现实生活中的接触式能量传输之效率同样远高于隔空传输，听到这就连水果铁粉都想把贵上天的Magsafe磁贴定义为百无一用的宗教圣器。
声波谐振器助力5G高性能射频滤波器发展
滤波器是一种选频装置，通过耦合基本元件或谐振器来实现，可以使信号中特定的频率成分通过，而极大地衰减其它频率成分。
【复材资讯】晶界，Nature！
研究背景在广泛的条件下（温度、压力、应变速率等），金属和合金的永久性或塑性变形是通过位错实现的，这些线性缺陷的存在和移动决定了晶体材料的力学行为。金属通常以多晶形式存在，其中每个晶体区域或晶粒由晶界分隔，而晶界是位错运动的已知障碍。
软件度量指标（架构指标）
指标如同系统中的一个开关,如果你打开它,系统可能会有不同的反应。找到合适的指标让系统达到预期效果很不容易。然而,弃之不顾不是明智之举。软件架构健康度优化常比喻为医生诊断疾病。指标度量非常重要,但不等同于医生的诊断。开发团队的专业知识和经验也至关重要。
打了昂贵的生物制剂还是没效？你差的可能是一把“细菌钥匙”
你有没有听过身边炎症性肠病（IBD，包括克罗恩病和溃疡性结肠炎）患者的绝望？打上了昂贵的“生物制剂”（抗TNF抗体，如英夫利西单抗、阿达木单抗），满怀希望，但几周甚至几个月后，医生无奈地摇头：效果不好，或者刚开始有效，后来就没用了。
