Stretchable and energy‐efficient neuromorphic devices based on ionic capacitance for robotic tactile recognition

open access: yesFlexMat, EarlyView.
Abstract Neuromorphic devices with learning and memory functions are critical for enabling human‐like tactile perception and interactive control in humanoid robots. However, existing neuromorphic platforms often struggle to reconcile mechanical flexibility with energy efficiency due to material and mechanism constraints.

Three‐dimensional hybrid perovskite heterostructure single crystals toward highly efficient x‐ray detectors

open access: yesInfoMat, EarlyView.
This study presents for the first time a self‐assembled three‐dimensional perovskite heterojunction single crystal with organic cations and Pb coordination, (MHy)2Pb(2)Cl4·Pb(1)Cl2 (MPC). The MPC possesses carriers with different conformations and undergoes an ordered–ordered structural transition as the temperature increases, which ultimately realizes

Rapid Detection of Klebsiella pneumoniae in Infants With Severe Infection Disease by Instant Nanofluorescent Microspheres‐Immunochromatography Combined With Recombinase Polymerase Isothermal Amplification Technology

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
Schematic illustration of the RPA‐FICTS platform for rapid detection of Klebsiella pneumoniae in infants. Genomic DNA extracted from clinical samples is amplified by recombinase polymerase amplification (RPA) targeting the mdh gene at 37°C, and the biotin‐ and digoxigenin‐labeled amplicons are subsequently detected on a nanofluorescent microsphere ...

Development and Analytical Validation of a Smartphone‐Based Quantitative Lateral Flow Immunoassay for Serum Cystatin‐C

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
We developed a gold nanoparticle‐based lateral flow immunoassay that pairs a fixed‐geometry smartphone reader with an Android application for quantitative serum Cystatin‐C measurement. The 15‐min assay covered 0.32–8.00 mg/L with a 0.15 mg/L detection limit and CVs below 10%.

Machine Learning‐Assisted Prediction and Analysis of Viscosity and Fusion Characteristics for Coal and Biomass Ash

open access: yesMaterials Genome Engineering Advances, EarlyView.
This study develops a machine learning framework for predicting the flow temperature and viscosity of coal and biomass ash with CatBoost and LightGBM as the optimal models. Feature analysis revealed composition‐property mechanisms, and symbolic regression was further applied to derive empirical formulas for rapid and accurate prediction.
