Prediction‐Based Algorithms for Long‐Range High‐Speed Force Spectroscopy

Journal of Molecular Recognition, Volume 39, Issue 5, September 2026.
ABSTRACT We present a high‐speed force microscopy platform mounted on a confocal microscope with a z sample stage enabling long‐range, high‐speed force spectroscopy measurements on biological samples. The control software is built on a field‐programmable gate array (FPGA)‐based data acquisition and processing system, complemented with a custom ...

Ambient Light‐Activatable Luminescent Particle‐Embedded Conformal Patch for Photochemical Tissue Bonding and Photobiomodulated Healing

Advanced Materials, Volume 38, Issue 44, 7 August 2026.
We report a wearable photonic patch integrating room light‐ and sunlight‐activatable luminescent particles (RSLPs) for both photochemical tissue bonding and photobiomodulation. RSLPs harvest ambient light and emit red luminescence to drive chlorin e6–mediated collagen crosslinking.

Evolutionarily conserved hydrophobicity and sterics in TM3/TM4 balance Orai1 pore opening

Protein Science, Volume 35, Issue 8, August 2026.
Abstract The calcium (Ca2+) channel Orai1—the pore‐forming subunit of the Ca2+ release‐activated Ca2+ channel—is opened by its physiological activator, the endoplasmic reticulum (ER)‐resident Ca2+ sensor stromal interaction molecule 1 (STIM1) upon ER Ca2+ store‐depletion.

Monolithic Stretchable Functional Fibers With Structurally Tunable Percolation Networks for Seamlessly Integrated Wearable Electronics

Small Structures, Volume 7, Issue 8, August 2026.
Monolithic, function‐tunable fibers have been demonstrated by engineering asymmetric AgNW percolation networks on elastic cores. Precise vertical encapsulation induces localized densification, enabling spatial tuning of strain‐sensitive and strain‐insensitive regions within a single architecture.

Techno-economic evaluation of five-level nested neutral point clamped converter topology for transformer-less connection of high-power wind energy conversion systems

Journal of Energy in Southern Africa, 2019
Developers and operators are interested in improving the reliability and reducing the associated costs of wind power plants (WPPs) because of the continuous increase in the power capacity of wind energy conversion systems (WECSs) and the increasing ...

Wood anatomical trait correlations with hydraulic efficiency and safety in an aseasonal wet tropical forest

Functional Ecology, Volume 40, Issue 8, Page 2701-2717, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Xylem anatomy underpins the capacity of trees to transport water while avoiding hydraulic failure, shaping species performance and resilience to climate change. However, the specific ways anatomical traits underpin hydraulic trade‐offs in tropical forests remain debated.

Improved Level Balancing with Diode-Clamped Multi-Level Inverter Configuration Based on Multi-Winding Transformer

Majlesi Journal of Electrical Engineering
A new configuration for a diode-clamped multi-level inverter based on a multi-winding transformer was proposed and simulated. The most important difference between this proposed DC-AC-AC structure and the basic structure is that; in the proposed ...
