Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

Benchmarking Organic Photodiodes at the Noise Floor

Advanced Optical Materials, EarlyView.
A precise measurement framework based on a calibrated, ultra‐low‐noise automated setup with open‐source Python scripts enables accurate benchmarking of photodiodes. The unique combination of time‐dependent current measurement under dark conditions, followed by continuous‐wave faint illumination, facilitates reliable extraction of photocurrent near ...

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, EarlyView.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

Nanoscale Mapping of the Subcellular Glycosylation Landscape

Advanced Science, EarlyView.
Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

Enhanced Photocatalytic Wastewater Purification and Bacterial Elimination via Copper Ion Irradiation‐Induced Modification of BiOCl

Advanced Science, EarlyView.
This study presents a copper ion irradiation method to achieve the modification function of BiOCl. By using high‐energy ion beams to introduce impurity ions inside the material, the intrinsic electric field of BiOCl is optimized, promoting the separation of photogenerated carriers and enhancing the photocatalytic activity.

Two Schemes Based on the Collocation Method Using Müntz–Legendre Wavelets for Solving the Fractional Bratu Equation

Axioms
Our goal in this work is to solve the fractional Bratu equation, where the fractional derivative is of the Caputo type. As we know, the nonlinearity and derivative of the fractional type are two challenging subjects in solving various equations.
