Summary: The low temperature toughness of BCC metals, such as chromium, can be greatly enhanced by designing a fine-grained structure. The fine grains act as dislocation sources, emitting easy glide edge dislocations at low temperature, which effectively slows down crack propagation and increases the toughness of chromium.

Summary: Metal growth is crucial for the efficiency and performance of processes in materials manufacturing or applications. This study focuses on the poorly understood growth of metal during oxygen removal from its oxides. The role of stress release in the formation of iron whiskers is investigated, and the superior stress release capabilities of hydrogen compared to carbon monoxide are emphasized. The development of a larger-sized nanoscale hole structure effectively inhibits the growth of whiskers.

Summary: The efficiency of electroporation treatments depends on the application of a critical electric field over the targeted tissue volume. A deep neural network trained on finite element model simulations was developed to predict tissue properties from a measured voltage ramp, showing minimal test error and great utility in clinical applications. The platform can quickly ascertain patient-specific tissue properties required for treatment planning.

Summary: Real-time digital polymerase chain reaction (qdPCR) integrates absolute quantification with process information, improving precision in molecular diagnostics. We propose a novel approach to determine optimal reaction conditions for qdPCR using real-time fluorescence monitoring in microwells. By leveraging an ultrathin laminated chip (UTL chip), we achieve faster amplification and higher accuracy, showing promise for molecular diagnostics.

Summary: This study developed a novel bioassay for monitoring FK506 using magnetic Janus micromotors and a recombinant chimera receptor. The bioassay utilized a fluorescence competitive method between the drug and the micromotors to achieve a one-step assay without washing steps. The method exhibited a high limit of detection and dynamic range, and was able to operate in raw samples.

Summary: Molecular monitoring in the dermal interstitial fluid (ISF) has the potential to screen markers of health and disease status in a painless manner. This study presents an innovative approach to address the poor patch stability of microneedle sensors on live rodents by using magnetic placement. Real-time pharmacokinetic measurements in live rats demonstrate the effectiveness of this approach. The future prospects and challenges of this technology are also discussed.

Summary: Peritectic couple growth (PCG) is an unusual growth form where the peritectic and pro-peritectic solid phases solidify similar to a regular eutectic. Experiments were conducted at the International Space Station to investigate the dynamics of PCG formation and growth using the organic peritectic alloy Tris(hydroxymethyl)aminomethane-Neopentylglycol. Both fully planar and partly planar/cellular PCGs were observed and analyzed. PCG initiates with the formation of lateral bands from the peritectic phase that overgrow most of the pro-peritectic phase but not completely. The remaining patches transform into rods and/or lamellae during coupled growth.

Summary: A high-entropy alloy (HEA) with low stacking fault energy and high strength was designed using the principle of heterostructure strengthening. The alloy exhibited a multi-scale heterogeneous microstructure containing hierarchical twins. It achieved ultrahigh yield strength, ultimate tensile strength, and large ductility at low temperature, surpassing most FCC HEAs reported so far and breaking the strength-ductility trade-off of conventional metal alloys. The extraordinary mechanical properties were attributed to a suitable strain hardening capability resulting from the synergistic effect of hetero-deformation-induced hardening, twinning-induced plasticity, and deformation-induced phase transformation.
