Yoshida and colleagues present a technique for sealing bedrock flow paths using concretion-forming resin, which is inspired by the natural process of spheroidal concretion formation in natural calcite. The approach shows high speed and durability, also proving a good performance in withstanding seismic activity.
In a Review Article, Jonathan Sauder and colleagues develop a framework to categorize the variety of deployable structures and mechanisms available for operation on small satellites.
Robin Neuder and colleagues investigate liquid crystals for phase tuning in reconfigurable intelligent surfaces based on defected delay lines. This approach enables liquid crystal reconfigurable intelligent surfaces that can be optimized towards wide bandwidth, low loss, and fast response time simultaneously.
Yushen Zhang and colleagues report an open source, interactive software platform for the efficient and convenient design of 3D printable microfluidic devices. The approach incorporates a design-for-manufacturing function, facilitating device fabrication using commercial consumer-grade printers.
Yixiong Zhao and co-authors present a passive refractive index sensor based on the sub-terahertz photonic crystal resonator. It serves as a non-electronic, compact, and low-cost solution for distributed remote sensing, applicable in monitoring airborne pathogens for pre-infection detection.
Syed Tariq Shah and colleagues use multi-antenna reconfigurable surfaces to maximise the accuracy of wireless indoor localisation. They study the achievable performance improvement using pre-trained machine learning techniques.
Leendert-Jan W. Ligtenberg and colleagues report an X-ray guided platform for the wireless teleoperation of hemocompatible, untethered magnetic robots. The approach will enable clinicians to reach and treat vascular diseases within the body where alternative tethered flexible surgical instruments offer more limited control.

Yibo Dong et al. implement a compact and robust diffractive neural network chip with a virtually unlimited lifetime for optical inference. The chip demonstrates high accuracy and high stability even after high temperature aging, aiming at applications in extreme environments.
Aasish Boora and colleagues implement low-power on-chip radio frequency receiver for high data rate Internet of Things applications. Their device can be reconfigurable to adjust power consumption to the data rate aiming at energy-efficient operation.
Alexander Blömeke and colleagues investigate the conditions under which the balancing resistors in battery systems can be used for impedance measurements. This helps to improve state estimation and results in safer and more sustainable battery systems.
Sonnemann and colleagues use Bayesian inference to obtain seabed geoacoustic properties. Their method allows resolving up to 10 cm thin sediment layers over wide areas.
Md Nasful Huda Prince and colleagues propose a tissue imaging system with isotropic sub-micron resolution. The method intelligently delineates tissue borders and captures images faster and with enhanced signal quality.
Hichem Guerboukha and colleagues present a reliable high-data-rate THz communications system when the line of sight between the transmitter and receiver is blocked. They design the near-field wavefront to generate a curved trajectory.
Yongjian Tan and colleagues report a universally applicable real-time polarization compensation method for quantum communications. The approach has several advantages over current methods, including a minimum number of waveplates, faster speed, and wider applicability for various optical links.
Lea Kollmannsperger and colleagues report the fatigue behaviour of additively manufactured lattice structures under cyclic loading, relating fatigue-induced properties to process characteristics using acoustic emission.
