Given the advantages of high energy density and easy deployment, biodegradable primary battery systems remain as a promising power source to achieve bioresorbable electronic medicine, eliminating secondary surgeries for device retrieval. However, currently available biobatteries are constrained by operational lifetime, biocompatibility, biodegradability, limiting potential therapeutic outcomes temporary implants. Herein, we propose fully zinc–molybdenum (Zn–Mo) with prolonged functional...
As nitric oxide (NO) plays significant roles in a variety of physiological processes, the capability for real-time and accurate detection NO live organisms is great demand. Traditional assessments rely on indirect colorimetric techniques or electrochemical sensors that often comprise rigid constituent materials can hardly satisfy sensitivity spatial resolution simultaneously. Here, we report flexible highly sensitive biosensor based organic transistors (OECTs) capable continuous wireless...
Abstract Neuromorphic electronics has demonstrated great promise in mimicking the sensory and memory functions of biological systems. However, synaptic devices with desirable sensitivity, selectivity, operational voltage imitating olfactory system have rarely been reported. Here, a flexible biomimetic synapse based on an organic electrochemical transistor (OECT) coupled breath‐figure derived porous solid polymer electrolyte (SPE) is proposed. The device demonstrates excellent sensitivity...
Abstract Optoelectronic neural interfaces can leverage the photovoltaic effect to convert light into electrical current, inducing charge redistribution and enabling nerve stimulation. This method offers a non-genetic remote approach for neuromodulation. Developing biodegradable efficient optoelectronic is important achieving transdermal stimulation while minimizing infection risks associated with device retrieval, thereby maximizing therapeutic outcomes. We propose biodegradable, flexible,...
In magnetotelluric (MT) simulations, the enforcement of Dirichlet boundary condition (BC) necessitates padding a region extension (ROE) to core interest (ROI) in model. The ROE typically has size several skin depths and hence computational domain can easily be hundreds kilometers for broadband MT surveys. A large number cells are therefore required discretize ROE, wasting computing resources solving electric field ROE. To address this issue, we developed 3D nested finite element algorithm...
Geophysical inversion usually involves ill-posed problem. Regularization is the most commonly used method to mitigate this There are many regularization parameter selection methods, among which adaptive can automatically update parameters during iteration, reducing difficulty of selection. Therefore, it widely in linear inversion. However, there very few studies on use methods stochastic optimization algorithms. The biggest that algorithms, search direction any iteration completely random....
The time-step sizes of the conventional finite-difference time-domain (FDTD) method are severely restricted by Courant-Friedrichs-Lewy stability condition. This may result in excessive iterations, high cost and large runtime, increasing late-stage cumulative errors 3D transient electromagnetic (TEM) forward modeling. At present, modeling speed is a major obstacle development TEM inversion. To address this issue, new algorithm presented. In algorithm, backward Euler (BE) scheme used with view...
Abstract The rapidly expanding severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) and its variants demand a continuous monitoring method through portable wearable devices.

Late-time negative responses in central-loop transient electromagnetic (TEM) data are often linked to the induced polarization (IP) effect. Early methods for modeling IP effect TEM try avoid calculating fractional derivative arising from considering Cole-Cole model by either using Fourier transform convert frequency-domain time domain or approximating directly. The frequency-to-time conversion method suffer accuracy issues if number of frequencies calculated is small. time-domain...
Data security risks of unauthorized access confidential information have attracted considerable attention. Transient electronics capable physical disappearance or disintegration upon external stimuli could potentially offer an alternative solution at the device level. Despite great advances, smart, efficient, wireless, and nonrecoverable degradation foundry‐compatible silicon (Si)‐integrated circuit (IC) chips remains a challenge. Herein, laser‐triggered Si circuits by lithiation moisture...

Subsurface karst features are significantly developed in Guangxi Province, China. This area mainly contains fractured subsurface rock, abundant channels, and widely distributed underground fissure networks. Such adverse geological conditions could potentially create hydrogeological hazards such as collapses, water inrush, mud inrush during infrastructure construction. The Hejing limestone mine is an opencast Pingnan County, Guangxi, that produces cement. Mining activities have altered the...
