Summary: To achieve higher output power with a smaller core volume, it is crucial to design the core and coil parameters of the freestanding magnetic field energy harvester (FSMFEH). However, the absence of an FSMFEH power model hinders the detailed design process. To address this issue, this article establishes an accurate power model of FSMFEH based on the H-shaped core, by quantifying coil mutual inductance and internal resistance as core and coil parameters. The proposed model allows for the design of optimal values for core column size, core lamination size, coil turns, and wire diameter. Experimental results demonstrate that the proposed model maintains high accuracy with a power density deviation within 5% compared to theoretical values, and the optimized parameters effectively improve power density, with a maximum power density of 4.182 mW/cm(3) and corresponding maximum output power of 13.25 mW achieved when the current of the busbar is 100 A.

Summary: We introduce a high-resolution white light quantitative phase nanoscopy (WLQPN) system for visualizing nanoparticles and subcellular features in biological specimens. The system utilizes the five-phase shifting technique and deconvolution to achieve super-resolution phase imaging. Compared to the Fourier analysis method, the phase shifting technique provides full detector resolution. The technique was tested on various samples and showed significant improvement in resolution.

Summary: Zinc oxide (ZnO) based nanomaterials are commonly used as heterogeneous catalysts, with twinned ZnO nanomaterials showing unique catalytic activities. The study found that O-Zn-terminated polar nanostructures have the highest stability, potentially serving as active sites for catalytic reactions. Structural and electronic calculations revealed that the total energies of twinned ZnO nanostructures are influenced by both surface and twinning boundary energetics, with the latter playing a more significant role.

Summary: This study proposes a method to design lead-free relaxors by using a combination of ferroelectric and paraelectric components, to achieve high capacitive energy storage. By selecting ferroelectric materials with large structural distortion and paraelectric components, relaxors with a tolerance factor close to 1 can be obtained, thus eliminating hysteresis and achieving large polarization under high electric breakdown. Through experiments, it is demonstrated that relaxors based on the Bi0.5Na0.5TiO3-SrTiO3 solid solution exhibit a slush-like structure and strong local polar fluctuations, resulting in a giant recoverable energy density of 13.6 J cm(-3) and an ultra-high efficiency of 94%.

Summary: Having an accurate model and well-estimated parameters is crucial for the photovoltaic system to increase conversion efficiency. Existing methods for identifying photovoltaic model parameters suffer from issues such as high computational cost and difficulty in achieving the best performance. To address these problems, a hunter-prey optimization algorithm is proposed, which incorporates mutual benefit and sharing mechanisms to improve the precision and convergence rate of the algorithm.

Summary: The IOTA blockchain system is a lightweight platform for Internet of Things applications, without heavy proof-of-work mining. It uses a directed acyclic graph (DAG) called Tangle to organize ledger data, rather than a traditional chain structure. This article presents the first theoretical model for the evolving IOTA tangle based on stochastic analysis. The analysis of real-world IOTA ledger data reveals a non-typical double Pareto Lognormal (dPLN) degree distribution in the IOTA tangle.

Summary: A synergistic two-step optimization strategy is proposed to improve the recoverable energy storage density, efficiency, and temperature stability of Sr0.7Bi0.2TiO3 (SBT)-based relaxor ferroelectrics. The strategy involves composition optimization to induce high activity and ultrafine polar nanoregions, and a two-step sintering process to produce ultrasmall grain size and compact grain boundaries. Competitive SBT-based lead-free relaxor ferroelectrics with high performance in capacitive energy storage are achieved.

Summary: The main challenges hindering the widespread use of organic-inorganic lead halide perovskites in modern technology are their long-term instability and lead contamination. Among environmentally friendly alternatives, Cs2SnX6 compounds have shown potential as ambient-stable, lead-free materials for energy harvesting and optoelectronic applications. The incorporation of Cs2SnX6 into polyvinylidene-fluoride (PVDF) boosts the electroactive phase in PVDF, leading to enhanced piezoelectricity in the composites.

Summary: In this paper, a novel algorithmic improvement framework is proposed to mitigate the impact of equifinality on hydrological model parameter calibration. The improved algorithm, HSRS_SCE, combines a hierarchical search and range shrinkage with the widely used SCE_UA algorithm. Results show that the HSRS_SCE algorithm outperforms traditional schemes in terms of calibrated parameter results and objective function values, while also reducing the search time through parallel computing.

Summary: Due to safety concerns with Li ionic batteries, solid electrolytes have been extensively researched. Li-rich anti-perovskite Li3OBr is considered a promising candidate, but achieving high ionic conductivity is challenging due to the crystal lattice's high intrinsic symmetry. This study presents a design strategy that introduces various point defects and grain boundaries to break the high lattice symmetry of Li3OBr crystal, and explores their effect and microscopic mechanism in promoting Li-ion migration.

Summary: The study found that leukocytes become significantly stiffer and more viscous when stimulated by microbeads mimicking target cells, with these mechanical changes starting within seconds and rapidly evolving over minutes. The elastic and viscous properties of leukocytes evolve in parallel, maintaining a specific ratio that constitutes a mechanical signature unique to each cell type.

Summary: The research designed a strategy to control the positioning, shape, spreading, mechanics, and activation state of T cells through protein microstamping. It was found that T cell activation capabilities were not affected by adhering onto different substrates, and expressing specific receptors in T cells led to similar activation capabilities. The system proposed in the study provides a way to test the activation or anergy of T cells with defined adhesion and mechanical characteristics.
