A chiral coupling between neighboring magnetic layers, the interlayer Dzyaloshinskii–Moriya interaction, has been utilized to assist spin-orbit torque to efficiently switch perpendicular magnetization of magnetic films free of any external magnetic fields, which can be promisingly applied to design spin-orbit torque magnetic random-access memories and other practical spintronic devices.

相邻磁层之间的手性耦合，即层间Dzyaloshinskii–Moriya相互作用，已被用于辅助自旋轨道转矩，以有效地切换没有任何外部磁场的磁膜的垂直磁化，这可以很有希望地应用于设计自旋轨道转矩磁随机存取存储器和其他实用的自旋电子器件。

An in vivo programmable tumor cells/T effector cells bispecific nano-immuno-engager improves immunotherapy against cancers. The peptidic nanoparticles bind the tumor cell surface α3β1 integrin and undergo in situ transformation into the nanofibrillar network. The prolonged retained nanofibrillar network at the tumor microenvironment captures T effector cells via activatable α4β1 integrin ligands.

Amorphizing nanostructured noble metals is important yet challenging in the field of electrocatalysis. With a glassy nucleation-assisted kinetic control strategy, a series of amorphous PdCu nanospheres and nanowires are achieved under mild conditions. Such amorphous catalysts, endowed with high surface reactivity, can efficiently cleave the C-C bond in ethanol electrooxidation.

非晶化纳米结构贵金属在电催化领域很重要但也具有挑战性。通过玻璃态成核辅助动力学控制策略，在温和条件下获得了一系列非晶态 PdCu 纳米球和纳米线。这种无定形催化剂具有高表面反应活性，可以在乙醇电氧化中有效裂解C-C键。

We demonstrate a conceptual model to achieve the ultrasensitive thermally activated upconversion in an energy-migratory erbium sublattice through controllable surface interactions. The high relative sensitivity (5.27% K−1) and thermochromic feature make it an ideal candidate toward noncontact nanothermometry, optical information encryption, and anticounterfeiting.

我们展示了一个概念模型，通过可控表面相互作用在能量迁移铒亚晶格中实现超灵敏热激活上转换。高相对灵敏度 (5.27% K−1) 和热致变色特性使其成为非接触式纳米测温、光学信息加密和防伪的理想候选者。

Single-atom-kernelled nanocluster catalyst, bridging single atom catalyst and nanocrystal catalyst, can not only provide multiple metal atom sites but also bear a higher surface atom ratio. Unfortunately, it is not reported yet. Here a Pd-based tri-metal nanocluster with a single-Ag atom-kernel was successfully synthesized for the first time by the introduction of some steric hindrance factors and employment of a joint alloying strategy that combines the co-reduction with an anti-galvanic reduction (AGR), which exhibits higher catalytic performance and Au utilization efficiency than the bimetal precursor nanocluster in the electrocatalytical reduction of CO2 to CO. Further investigations reveal that the kernel single atoms from both Au4Pd6 and Au3AgPd6 are not the active sites for catalysis, but they exert an influence on the electronic structure and thus affect the catalytical properties as well as other properties.

单原子kernelled纳米团簇催化剂，桥接单原子催化剂和纳米晶体催化剂，不仅可以提供多个金属原子位点，而且具有更高的表面原子比。不幸的是，目前还没有报道。通过引入一些空间位阻因子并采用联合合金化策略，首次成功合成了具有单个Ag原子核的Pd基三金属纳米团簇，其在CO2电催化还原为CO中表现出比双金属前体纳米簇更高的催化性能和Au利用效率。进一步的研究表明，来自Au4Pd6和Au3AgPd6的核单原子都不是催化的活性位点，但它们对电子结构产生影响，从而影响催化性能以及其它性能。

This work demonstrates a novel strategy to kinetically control enzyme-instructed self-assembly of the peptides in living cells by using host‒guest complexation. Our results indicate that the host‒guest complexation can selectively form cytotoxic nanostructures in mitochondria of cancer cells and induce cancer cell death, mainly through ferroptosis in vitro and in vivo. This study provides a general strategy to selectively program cancer cell death by modulating the intracellular self-assembly of the peptide.

这项工作展示了一种通过使用主客体络合来动力学控制活细胞中酶指导的肽自组装的新策略。我们的结果表明，主客体络合可以在癌细胞的线粒体中选择性地形成细胞毒性纳米结构，并主要通过体外和体内的铁死亡来诱导癌细胞死亡。这项研究提供了一种通过调节肽的细胞内自组装来选择性编程癌细胞死亡的一般策略。
