Advanced Functional Materials, EarlyView.Phase‐field modeling reveals the mechanisms behind short‐term ferroelectric imprint in Hf0.5Zr0.5O2 polycrystalline thin films. Combined with a charge trapping model, the proposed framework accurately reproduces coercive field shifts with pause time and their recovery through field cycling in polarization‐voltage measurements, offering valuable ...

Measurement method of reverberation field reciprocity parameter
Zhongguo Jianchuan Yanjiu, 2017 This paper presents a method for measuring the reciprocity parameter based on the free field. It is able to achieve accurate measurement of the reverberation constant in a narrow band. The method uses the same transmitting and receiving system, and keeps

No Evidence for [O III] Variability in Mrk 142
, 2016 Using archival data from the 2008 Lick AGN Monitoring Project, Zhang & Feng (2016) claimed to find evidence for flux variations in the narrow [O III] emission of the Seyfert 1 galaxy Mrk 142 over a two-month time span.

Reverberation time measurements of a neonatal incubator
Applied Acoustics, 2020 Abstract New-borns are exposed to high noise levels inside infant incubators. Some authors suggest that these noise levels are amplified by the reverberant nature of the materials that compose incubators. In this paper, the impulse response and the reverberation time of an incubator with standard dimensions were calculated.

Kidney Stone Dissolution By Tetherless, Enzyme‐Loaded, Soft Magnetic Miniature Robots
Advanced Healthcare Materials, EarlyView.Wireless magnetic robots are developed for kidney stone dissolution. The robots navigate through a urinary tract model from bladder and ureter to renal pelvis with the help of external magnetic fields. The filaments are loaded with urease enzyme which catalyzes urea to carbon dioxide and ammonia, thereby increasing pH to basic regime and supporting ...

Lymphoid and CXCR4 Cell Targeted Lipid Nanoparticles Facilitate HIV‐1 Proviral DNA Excision
Advanced Healthcare Materials, EarlyView.Advancements in ART improve HIV‐1 patient outcomes but are unable to eliminate latent viral DNA. To address this, CXCR4‐targeted lipid nanoparticles (T‐LNPs) for delivering CRISPR‐Cas9 to excise HIV‐1 DNA in infected cells are developed. These T‐LNPs achieve ≈60% HIV‐1 DNA excision efficacy in blood and splenic tissue, demonstrating promise for ...
