However, polymer materials used to prepare hydrogels typically have antioxidant properties, which easily react with RONS and reduce loading efficiency. Here, we propose a simple and low-cost polymer oxidation method based on plasma oxidation pretreatment to enhance the loading capacity of polymers for RONS. Taking hyaluronic acid (HA) as an example, first, through discharge mode control, plasma (main RONS component is N 2 O 5 ) is generated in the transition mode to oxidize HA. The reductive hydroxyl groups adjacent to HA are oxidized to aldehyde groups, and low pH plasma oxidized pretreated HA (PHA) is obtained. To prevent the irritating effects of high concentrations of H + and aldehyde groups on the human body, we prepared acid-base neutralization PHA (NHA), in which we titrated an alkaline solution to neutralize H + and reacted with aldehydes to form hydroxyl and carboxyl groups. Further studies revealed that NHA does not have bactericidal effects by itself, but plasma-activated NHA has a greater RONS loading capacity and bactericidal effect than plasma-activated HA (PAHA), as well as lower irritation (one fifth of the H + concentration of PAHA). This study is expected to provide a strategy for promoting the preparation efficiency, bactericidal effect and biosafety of PAH.","PeriodicalId":16789,"journal":{"name":"Journal of Physics D: Applied Physics","volume":"58 39","pages":"395203-395203"},"PeriodicalIF":0.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147909917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the abrupt dielectric contrast at interlayer interfaces often results in localized electric field distortion, undermining breakdown reliability.

Dry disinfection using high-concentration gaseous high valence NO x risks air pollution, while spraying plasma-activated water (PAW) suffers from uneven coverage and prolonged treatment times. This paper utilizes a hybrid plasma configuration to generate plasma-activated gas (PAG) rich in high valence NO x , which is then combined with water mist for surface disinfection. Experimental results demonstrate that PAG-driven mist achieves complete inactivation of methicillin-resistant S. aureus and E. coli in the shortest time compared to direct PAG exposure or atomized PAW. Pre-spraying deionized water mist followed by PAG achieves comparable efficacy to PAG-driven mist, suggesting synergistic gas–liquid interactions. Mechanism analysis reveals that water mist maximizes the utilization of gaseous reactive species in PAG, enabling surface enrichment of aqueous reactive species (e.g. ONOO – , O 2 – ). Scanning electron microscopy and biomolecule leakage assays confirm bacterial membrane disruption as the primary inactivation pathway. Notably, PAG-driven mist absorbs most gaseous O 3 and NO x with minor post-treatment residues. This paper reveals that water mist can enrich high valence NO x due to its high solubility, thus achieving high-level and low-pollution disinfection, advancing plasma technology for environmental and medical sterilization.","PeriodicalId":16789,"journal":{"name":"Journal of Physics D: Applied Physics","volume":"58 36","pages":"365205-365205"},"PeriodicalIF":0.0,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147884413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray phase contrast imaging, offering superior contrast-to-noise ratios in soft tissues, can in principle overcome this limitation. This study explores the feasibility of x-ray strain imaging for soft tissues using edge illumination (EI), a laboratory-based x-ray phase contrast technique. A phantom mimicking the mechanical properties of healthy and tumorous soft tissues, with a stiff inclusion invisible to conventional x-ray imaging, was tested alongside chicken soft tissue fixed in ethanol. While our study confirmed that EI phase contrast imaging provides improved contrast for such samples compared to absorption imaging, it also revealed a reduction in strain retrieval precision. Artefacts caused by absorbing bridges in the mask design and errors arising from differential phase signal integration, which vary spatially between scans, were identified as key limiting factors. Consequently, EI phase contrast strain imaging was unable to locate phantom inclusions based on mechanical contrast. However, EI's capability to increase spatial sampling frequency without compromising the field of view improved strain retrieval precision using its absorption contrast beyond that achieved with conventional x-ray strain imaging. These findings highlight the potential and challenges of applying EI to strain analysis in soft tissues, providing insights into its limitations and opportunities for further improvement.","PeriodicalId":16789,"journal":{"name":"Journal of Physics D: Applied Physics","volume":"58 31","pages":"315402"},"PeriodicalIF":3.2,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12319699/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144789353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its non-ionizing nature, low background signal from biological matrices, high contrast, and relatively good spatial and temporal resolution, MPI has been actively studied and applied to biomedical imaging and is expected to reach the clinical stage soon. To further improve the spatial resolution limit in MPI, researchers have been working towards optimizing the image reconstruction algorithms, magnetic field profiles, tracer designs, circuitry, etc. Recent studies reported that lower excitation field amplitudes can improve spatial resolution, though this comes at the expense of lower MPI signal and tracer sensitivity. Different excitation field profiles directly affect the collective dynamic magnetizations of tracers recorded by the receiver coil in MPI. However, there is a gap between understanding the relaxation dynamics of MNP tracers, the signal-to-noise ratio (SNR) of MPI signals, and the MPI spatial resolution. In this work, we used a stochastic Langevin equation with coupled Brownian and Néel relaxations to model the magnetic dynamics of different MNP tracers subjected to varying excitation fields. We analyzed the collective time-domain dynamic magnetizations (M-t curves), magnetic-field hysteresis loops (M-H curves), point spread functions (PSFs), higher harmonics, and SNR of the third harmonic to understand how the excitation field affects MPI performance. We employed Full Width at Half Maximum and SNR as evaluation metrics for imaging resolution and signal quality, respectively. Our study supports previous findings on the impact of excitation field amplitude on MPI performance while offering more profound insights into the interplay of nonequilibrium Néel and Brownian relaxation, tracer core size, and SNR.","PeriodicalId":16789,"journal":{"name":"Journal of Physics D: Applied Physics","volume":"58 30","pages":"305002"},"PeriodicalIF":3.2,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12281415/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144698900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In actual use, a surface protective coating and covering layer will always form on the surface of the device, which can affect the photodetection performance. In this paper, single CuO and Fe 2 O 3 layers were first prepared on the surface of a photoconductive detector based on a silicon wafer. The results demonstrate that the CuO and Fe 2 O 3 layers both improve the responsivity of the detector. The maximum responsivity can reach 286 mA W −1 at 515 nm for the device covered by the CuO layer. The heterojunction formed between the oxide layer and silicon wafer is the main reason for the improved performance. After inserting SiO 2 as a dielectric layer, the SiO 2 /CuO layer covered device exhibited weak photoresponse characteristics, while the SiO 2 /Fe 2 O 3 layer covered device still showed enhanced performance in the UV and visible light regions. The maximum responsivity of the SiO 2 /Fe 2 O 3 layer covered device was 61 mA W −1 at 515 nm, which is higher than that of the original detector based on silicon wafer (4.37 mA W −1 at 515 nm). The capacitor effect formed on both sides of the SiO 2 layer is the main reason for this phenomenon.
