A soft hybrid multi‐wavelength PPG wearable acquires neonatal signals. Synchronized PPG and invasive ABP data are segmented into fixed windows. A 1D‐EfficientNet model predicts segment‐level SBP and DBP. Model performance is examined with retrospective subgroup analysis across acquisition conditions.

Single‐Atom‐Enhanced Fully Inkjet‐Printed Electrochemical Sensor for Dopamine Detection
Fully inkjet‐printed paper‐based dopamine sensors are fabricated using nitrogen‐doped graphene acid functionalized with copper single atoms. The copper sites uniquely enhance dopamine oxidation through strong molecular adsorption, as verified by electrochemical measurements and DFT calculations. The approach highlights the potential of single‐atom inks

Long‐Chain Molecule Reconstruction of Novel Solvation Structure to Stabilize Zinc Metal Anode
Triethylene glycol diacetate (TGD), with unique long‐chain characteristics and rich oxygen‐containing functional groups, was used as an electrolyte additive to reconstruct the solvation structure. TGD can reduce the erosion of H2O molecules on the Zn anode, effectively homogenize the electric field distribution. Therefore, the Zn//Zn symmetric cell can

Atomically correlated phosphorus–sulphur sites are introduced into graphitic carbon nitride to regulate charge distribution, suppress localized trapping, and enhance oxygen activation. The resulting metal‐free photocatalyst selectively promotes the two‐electron oxygen reduction pathway, enabling efficient hydrogen peroxide production in pure water ...
