Summary: The development of high-precision, non-destructive, and 3D in situ imaging technology for detecting micro-scale damage inside polymers is challenging. A recent study discovered that electrical trees induced by an applied electric field in silicone gel can generate self-excited fluorescence, enabling successful high-precision, non-destructive, and 3D in situ fluorescence imaging of polymer damages. This pioneering discovery allows for the precise positioning of damaged areas by slicing the sample in vivo, providing a solution to the problem of imaging internal damage in insulating materials and precision instruments.

Summary: The authors developed a technique for spatial and spectral resolution on the nanometer scale to reveal the optical field inside a nanophotonic particle accelerator. Controlling optical fields on the subwavelength scale is crucial in nanophotonics. Laser-driven nanophotonic particle accelerators offer a compact alternative to conventional radiofrequency-based accelerators.

Summary: This study investigates the feasibility of using Electrical Capacitance Volume Tomography (ECVT) for monitoring three-dimensional water penetration. By developing and evaluating ECVT sensors with top electrodes and reconstruction algorithms, the process of moisture ingress into bricks with different cracks was successfully visualized, with good agreement with known properties of unsaturated water transport.

Summary: We theoretically study the domain wall (DW) magnons, which are elementary collective excitations of magnetic DWs, in easy-axis layered van der Waals (vdW) antiferromagnets and find that they behave as normal modes of coupled spin superfluids. Due to spin-charge coupling in vdW magnets, these DW magnons can be activated by voltage-induced torques, providing a low-dissipation and nanoscale excitation path. The electrical activation and the number of DW magnons at a frequency can be controlled by applying a symmetry-breaking static magnetic field, offering tunability of signal transmission. Our results demonstrate the potential of domain walls in vdW magnets for coherent spin information routing in spintronics and magnetism explorations.

Summary: This paper proposes a new two-step algorithmic method to improve the accuracy of moisture imaging in building walls using electrical impedance tomography (EIT). The problem of assessing dampness in buildings is important for various reasons, including cultural heritage, economics, safety, real estate aesthetics, and the health of occupants. The main challenge in EIT development is solving the ill-posed and inverse problem of obtaining reliable high-resolution moisture distribution images. To address this, the paper introduces a double-stage neural network approach that incorporates the use of a second network to enhance the images obtained from the first network. Both neural networks are trained on a similar set of pattern output images, with the first network generating training images for the second network. The use of LSTM network and a unique approach to input measurements and images further contribute to the effectiveness of the proposed method.

Summary: This paper studies the scattering of spin waves by a domain wall in an anisotropic ferromagnet. It is found that the transmission coefficient is non-zero and the transmitted waves experience a lateral shift, which can be greatly enhanced by arranging an array of well-separated domain walls. This has important implications for controlling spin waves in magnonic devices.

Summary: This study addresses an inverse scattering problem for synthetic aperture radar (SAR) data in through-the-wall imaging, utilizing a fully nonlinear model that shows better accuracy in estimating dielectric constants and target locations compared to the commonly used linearized models. The results demonstrate the effectiveness of the proposed method in accurately estimating dielectric constants and target locations hidden behind walls.

Summary: A new extension of a 1D mathematical model is proposed to describe diffusion limitation in a catalytic filter wall. The model considers transport limitations in both flowing gas inside free pores and in the coated catalyst, as well as Langmuir-Hinshelwood reaction kinetics with inhibition effects. By comparing the computed 1D concentration profiles with detailed 3D pore-scale simulations, the best agreement is achieved when gas-in-pores and intra-catalyst diffusion with LH effectiveness factor are considered. The extended model predicts the presence of undesired reactant slip at high flow rates, which was not possible with previously published models.

Summary: By combining wide-field and point detection modalities, this study explores the dynamics of optical trapping under femtosecond pulsed excitation. The radial trajectories of trapped particles are mapped from backscatter fluctuations, while the temporal evolution of two-photon fluorescence marks the onset of trapping involving multiple particles. The simultaneous confocal detection of backscatter and two-photon fluorescence estimates axial trap stiffness, revealing short-time trapping dynamics and inter-particle interactions within the trap. These findings are crucial for achieving controlled manipulation using optical nonlinearity under femtosecond pulsed excitation.
