Two‐Photon Fluorescence and Second‐Harmonic Generation Microscopy: Principles and Biomedical Applications

open access: yesJournal of Biophotonics, Volume 19, Issue 10, October 2026.
Compared with single‐photon methods, TPM enables deep‐tissue imaging using near‐infrared light, with excitation confined to the focal plane, thereby reducing photodamage. SHG microscopy images noncentrosymmetric biological structures such as collagen and myosin without fluorescent labels, offering direct structural contrast.

A Reproducible MRI‐Based Pipeline for Longitudinal Tracking of Laser‐Assisted Bioprinted Cells in Three‐Dimensional Constructs

open access: yesNMR in Biomedicine, Volume 39, Issue 10, October 2026.
Laser‐assisted bioprinting was used to deposit iron oxide‐labelled endothelial cells in predefined patterns onto SCAP‐seeded gelatin biopapers to assemble multilayer constructs of increasing thickness. T2*‐weighted MRI monitored constructs for up to 35 days.

Strain‐Dependent Evolution of Fatigue and Oxidation Damage in a Nickel‐Based Single‐Crystal Superalloy: The Dominant Mechanism Under Low‐Cycle and Thermomechanical Fatigue

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Systematic studies on the fatigue deformation and damage mechanisms of nickel‐based single‐crystal superalloys (Ni‐SXs) under combined thermal and mechanical conditions remain limited, particularly regarding the influence of strain amplitude on the relative contributions of fatigue and oxidation damage.

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
