Organic retinomorphic sensors offer the advantage of in-sensor processing to filter out redundant static backgrounds and are well suited for motion detection. To improve this promising structure, here, the key role of interfacial energetics in promoting charge accumulation to raise the inherent photoresponse of the light-sensitive capacitor is studied. Specifically, incorporating appropriate interfacial layers around the photoactive layer is crucial to extend the carrier lifetime, as confirmed by intensity-modulated photovoltage spectroscopy. Compared to its photodiode counterpart, the retinomorphic sensor shows better detectivity and response speed due to the additional insulating layer, which reduces the dark current and the RC time constant. Lastly, three retinomorphic sensors are integrated into a line array to demonstrate the detection of movement speed and direction, showing the potential of retinomorphic designs for efficient motion tracking.

Advanced oxidative processes of persulfate (PS-AOPs) have promising applications in antibiotic wastewater treatment due to their strong oxidation capacity and good selectivity. In this study, Sargassum fusiforme was selected as a raw biomass, and ZnCl2 carbonation-pyrolysis was adopted to prepare zinc chloride modified sheep sorrel biochar which was used as a catalyst to catalyze persulfate (PDS) to degrade the norfloxacin (NOR) in the water. The results showed that different ratios of ZnCl2 doping would significantly affect the performance of biochar, and the catalytic efficiency of the prepared biochar was optimal when the ratio of algal powder to ZnCl2 was 1∶1. Moreover, SEM, BET, XRD characterizations were employed to investigate the physical and chemical properties of YQZn in order to further explore the modification mechanism of ZnCl2. The catalytic efficiency result of YQZn under different conditions showed that the biochar had the best NOR removal rate of 95.09% under the conditions of PDS concentration was 1 mmol·L-1, modified biochar addition was 0.3 g·L-1, pH=9 and NOR concentration was 10 mg·L-1. SO4·-, HO· radicals, and 1O2 played a leading role in activating PDS in the system by free radical quenching. To solve the difficulties in biochar powder recovery YQZn geopolymer composite catalyst (GB) was prepared by using biochar loaded on porous geopolymer. The results showed that GB had excellent degradation activity and reuse performance, which successfully realized the loading and recycling of biochar, and thus had great potential for continuous treatment of norfloxacin in water.(过硫酸盐高级氧化工艺（PS-AOPs）因具有氧化能力强、选择性高等优点在抗生素废水处理方面具有广阔的应用前景。选取羊栖菜为研究对象，采用氯化锌（ZnCl2）共热裂解法，制备了ZnCl2改性羊栖菜生物炭（YQZn），并将其作为催化剂活化过二硫酸盐（PDS），降解水体中的诺氟沙星（NOR）。结果显示，不同的ZnCl2添加量对生物炭催化活性的影响不同，当ZnCl2与羊栖菜的质量比为1∶1时，催化活性最佳。采用扫描电镜（SEM）、Brunauer-Emmet-Teller（BET）方法、X射线衍射（XRD）分析等表征YQZn的理化性质，探究了ZnCl2的改性机理，同时研究了不同反应条件对YQZn催化活性的影响。结果表明，在PDS浓度为1 mmol·L-1、改性生物炭添加量为0.3 g·L-1、pH为9、NOR浓度为10 mg·L-1的条件下，NOR的去除率最高，可达95.09%。自由基淬灭实验结果表明，SO4·-和HO∙自由基在氧化作用中占主导地位，1O2的作用较为有限。针对粉末生物炭回收困难的问题，将YQZn负载至多孔地质聚合物上，制备了复合物GB。重复利用性实验表明，GB具有良好的降解活性和优良的重复利用性，可有效去除96.68%的NOR。)

The variation rule of deformation structure and magnetic properties of high strength non-oriented electrical steel with cold rolling were studied by field emission scanning electron microscopy(SEM+EBSD), rapid temperature tube furnace and AC magnetic properties measuring instrument. The results show that the rough strips with a large number of substructures and smooth strips with a small amount of deformation are formed in cold-rolled high strength non-oriented electrical steel. The rough strip has a γ orientation, mainly {111}〈110〉, and the smooth strip has a {112}〈110〉 and {001}〈110〉 orientation. In the rough strips, there are a lot of shear bands with width of about 2-3 μm, which show an angle of 20°-35°to the rolling direction. And the quantity increases gradually with the increase of the reduction rate. There is a certain misorientation between the shear band and the matrix. With the increase of the reduction rate, the shear band gradually changes from {111}〈110〉 to {223}〈110〉, and the misorientation between the shear band and the matrix gradually increases. After annealing, the texture of Goss and {111} increases, while the texture of {001} decreases. The rolling direction magnetic induction intensity increases, the transverse magnetic induction intensity decreases, the magnetic anisotropy is significant, and the iron loss decreases.

Non-intrusive sensors that can be attached to marine species offer opportunities to study the impacts of environmental changes on their behaviors and well-being. This work presents a thin, flexible sensor tag to monitor the effects of dissolved oxygen and salinity on bivalve gape movement. The measurement range studied was 0.5-6 ppm for the dissolved oxygen sensor and 4-40 g kg-1 for the salinity sensor. The curvature strain sensor based on electrodeposited semiconducting fibers enabled measurements of an oyster's gape down to sub-mm displacement. The multiplexed sensors were fabricated by low-cost techniques, offering an economical and convenient platform for aquaculture studies.

Nitrate is an important marker of water quality that can be challenging to detect in seawater due to the presence of multiple chemical interferants and high background chloride. Here, we demonstrate a compact microfluidic device that incorporates electrochemical desalination to selectively remove the interfering chloride ions and improve the detection limit of the downstream potentiometric nitrate sensor. The microfluidic platform was fabricated by a low-cost cut-and-lamination approach, and the detection mechanism was based on potentiometric measurements at an Ag/AgCl electrode coated with a nitrate-selective membrane. The sensor system achieved a detection limit of 0.5 mM with a sensitivity of 11.3 mV/dec under continuous flow.

Objective To establish a simple and rapid qualitative and quantitative detection method of dexmedetomidine in blood. Methods Blood was separated on the Allure PFP Propyl liquid chromatography column with isocratic elution after it was precipitated by acetonitrile and filtered. Qualitative and quantitative analysis of dexmedetomidine was performed using positive ion scan mode and multi-reaction monitoring mode. Results The limit of detection of dexmedetomidine in blood was 0.2 ng/mL and the limit of quantification was 0.5 ng/mL. The linearity of the method was good in the range of 0.5-1 000 ng/mL, and the correlation coefficient was greater than 0.99. The accuracy of the method was 90.34%-112.67% and the extraction recovery was 50.05%-91.08%, with no significant matrix effect. Conclusion This method is simple, selective and suitable for the qualitative and quantitative analysis of dexmedetomidine in blood, which can provide a reference for drug-facilitated cases involving dexmedetomidine.
