The global demand for sustainable materials and carbon-neutral technologies drives innovations in biochar, a carbon-rich material for energy storage, pollution mitigation, and carbon sequestration. Conventional biochar, limited by poor conductivity and porosity, relies on fossil fuel-dependent activation. Recent advances in gene-editing technologies enable the precise reduction of lignin and enhance cellulose in woody biomass, improving its processability for biochar production.

Torrefied biochar, a promising solid biofuel produced via moderate thermal biomass processing, enhances energy density and hydrophobicity but remains vulnerable to microbial degradation under humid, warm storage conditions. This review explores the mechanisms and risks of microbial corrosion, emphasizing the roles of bacteria, fungi, and actinomycetes in biochar deterioration through enzymatic breakdown, acid production, and biofilm formation. Feedstock composition, particularly lignin and mineral content, and environmental parameters critically influence microbial activity.

We describe steps for delivering GCaMP6f and ChrimsonR viruses and implanting the gradient-index (GRIN) lens for use with an Inscopix microscope. We then detail procedures for single-neuron tracking over an extended period through longitudinal recording and data smoothing and processing to enhance analysis.

Non-contact human respiration rate monitoring can be used for sleep apnea detection and home care. Typically, the human body does not remain stationary for long periods, and body movement can significantly affect the performance of non-contact respiratory monitoring. Because the breathing rate generally remains stable over short periods, using measurements from only a portion of the radar echo signals does not result in significant errors, and these errors will be smaller than those caused by body movement.

This research focused on examining how various UV light wavelengths (UVC, UVB, and UVA) influence the adsorption behavior of aged polyethylene (PE) MPs toward tetracycline (TC). To explore the adsorption mechanism in detail, adsorption kinetics were studied under different UV light wavelengths.

Very few studies have utilized artificial neural network (ANN) modeling for plastic thermal conversion, such as predicting fuel yield from mixed plastics and performing sensitivity analyses to identify which plastics produce more oil. Meanwhile, no study has conducted a comparative analysis of different models for catalytic and non-catalytic thermal conversion of various plastics, nor has a sensitivity analysis of process parameters using ANN for oil production.

Here, we show that formalin-induced pain behaviors coincide with increased responses in glutamatergic neurons within the anterior paraventricular nucleus of the thalamus (PVA). Furthermore, we describe non-overlapping subpopulations of PVAVgluT2 neurons involved in sensory and affective pain processing, whose activity varies across different pain states.

As an emerging two-dimensional (2D) material, MXene has garnered significant interest in advanced energy storage systems, yet the stackable structure, poor mechanical stability, and lack of moldability limit its large-scale applications. To address this challenge, herein, the self-assembly of MXene on carbonization-free wood was obtained to serve as high-performance electrodes for symmetrical all-wood eco-supercapacitors by a steam-driven self-assembly method. This method can be implemented in a low-temperature environment, significantly simplifying traditional high-temperature annealing processes and generating minimal impact on the environment, human health, and resource consumption.
