Summary: Quantum entanglement and squeezing have improved phase estimation and imaging beyond the classical limits in interferometric settings. However, the advantage of quantum in non-interferometric phase imaging methods commonly used in the classical domain, such as ptychography and diffractive imaging, is still lacking. In this study, we demonstrate the enhancement of imaging a pure phase object in a non-interferometric setting by exploiting entanglement, measuring only the phase effect on the free-propagating field.

Summary: A study introduces an ultra-thin dry epidermal electrode that conforms to the skin, accurately measures electrophysiological signals, and exhibits low sheet resistance, high transparency, and mechano-electrical stability. The enhanced optoelectronic performance is attributed to the synergistic effect between graphene and PEDOT:PSS, allowing for the accurate monitoring of electrophysiological signals in humans with reduced motion artifact interference.

Summary: The high performance humidity sensor reported in this letter utilizes nanoforest technology to significantly improve sensitivity by 15 times within a relative humidity range of 10-90%. Integration of a micro-heater reduces humidity response time by 8 seconds, while the use of a reference capacitor helps to eliminate parasitic capacitance and improve accuracy. The sensor's simple fabrication process and compatibility with CMOS processes make it suitable for batch production and potential replacement of existing low-performance sensors.

Summary: Modeling non-electrical processes using equivalent electrical circuits is a well-known and successful technique in research and development. Although finite element methods have become more popular in recent years due to their accuracy and intuitiveness, analogies still have advantages in certain cases. Using lumped circuits and graphs allows researchers to view the system from a different perspective, solve non-electrical systems using standardized electrical circuit methods, and take advantage of the capabilities of electrical circuit simulators.

Summary: In this work, intrinsic noise sources in electrostatic MEMS were investigated and quantified, with a focus on their impact on the mass sensitivity of bifurcation-based inertial sensors. Experiments were conducted to measure the power spectral densities of mechanical-thermal noise and electric-thermal noise, and a stochastic model of the sensor was presented. The model showed that thermal noise caused an uncertainty of 2 Hz in the bifurcation frequency, leading to stochastic switching between stable orbits.

Summary: In this study, CBS glass/Al2O3 composites were developed for LTCC applications based on a CaO-B2O3-SiO2 (CBS) glass system with a high boron content. The study revealed that the softening of glass and interfacial reaction between the glass and Al2O3 were the two most important factors affecting LTCC's densification process. Real-time shrinkage rate of LTCC during sintering was successfully simulated, and it was proven that the formation of the CaAl2(BO3)O phase played a significant role in reducing glass viscosity and promoting dense structure formation. The resulting LTCC composite exhibited excellent performance for high-frequency applications.

Summary: In this study, the disordering caused by swift heavy ion irradiation in two different compositions of pyrochlore structures was investigated. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy were used to analyze the samples before and after irradiation. It was found that both compositions underwent amorphization due to irradiation, with a slower rate observed in Nd1.8Zr2.2O7.1. The irradiation-induced modified track region in Nd1.8Zr2.2O7.1 consisted of defect-rich pyrochlore structure, anion-deficient fluorite structure, and amorphous domains.

Summary: Silicide ceramics, including tantalum disilicide (TaSi2), are known for their exceptional physical properties but are limited in practical applications due to their inherent brittleness at room temperature. In this study, we successfully improved the mechanical properties of TaSi2 ceramics and increased their electrical conductivity by modifying the preparation methods and sintering conditions. These findings provide valuable insights for future applications of TaSi2 and the design of advanced ceramic materials.

Summary: Microstructure design plays a crucial role in regulating the microwave dielectric properties of materials, however, the understanding of frequency temperature stability and related micromechanism remains limited. In this study, a combination of first-principles calculations and experimental observation was used to investigate the correlation among sintering behavior, crystal structure, bonding nature, and microwave dielectric properties of LnPO(4) (Ln = Eu, Pr) ceramics. The research findings systematically clarify the optimized effect and micromechanism of lanthanides on the dielectric properties of monazite ceramics, providing insights into the design and enhancement of microwave dielectric materials.

Summary: The study investigates the frictional and wear behaviors of carbon fiber-reinforced SiC ceramic matrix composites with different fiber orientations mating with ceramic balls. The results show that fiber orientation significantly affects the friction and wear properties of the composites. Pads with randomly arranged fibers demonstrate better friction stability and lower wear volume, potentially suitable for bearing material applications. The research also explores the factors influencing the formation of continuous tribo-film and identifies abrasive wear and oxidation wear as the dominant wear mechanisms for the friction pairs.

Summary: This study reveals the significant influence of resting time on the rheological properties of cement suspensions, which is closely related to non-absorbed polycarboxylate superplasticizers (PCEs) size variation. Adsorbed PCE during resting tends to bridge particles instead of dispersing them, leading to an increased yield stress.

Summary: This study investigates the effect of K/Na ratio on the phase structure, ferroelectric domains, and piezoelectric properties of potassium sodium niobate (KNN)-based ceramics. It reveals that high Na+ content leads to large ferroelectric domains, while high K+ content results in local polarity heterogeneity and distinct dielectric relaxational behavior. The balanced local polarity and stress heterogeneities contribute to improved piezoelectricity.

The results revealed the instability of the muscovite lattice under irradiation, as well as the expansion and shrinkage of the lattice with increasing dose. The study also identified changes in chemical structure and other mechanisms involved. These findings are significant for the design of radiation-resistant silicate materials and the manufacturing of electronic components used in the aerospace industry.
