Temperature Monitoring of Iron Molybdate Catalysts during ODH Reactions Using Coupled Operando Raman/XRD Analysis

open access: yesChemCatChem, Volume 18, Issue 19, 14 October 2026.
Exothermic reactions can cause a temperature increase in the catalyst bed under operating conditions. We introduce a novel approach to measure the catalyst temperature based on operando Raman/X‐ray powder diffraction (XRD) analysis and illustrate its application to the depth‐dependent temperature monitoring of iron molybdate catalysts during oxidative ...

Moderate Biochar–Compost Mixture Is More Effective in Improving Biomass, Nutrient Fluxes, and Photosynthetic Outputs for Sustainable Land Restoration and Soil Fertility

open access: yesLand Degradation &Development, Volume 37, Issue 16, Page 12004-12017, October 2026.
ABSTRACT Soil nutrient depletion severely constrains crop productivity in degraded and saline environments. Strategies such as biochar–compost integration could be useful for sustainable agriculture and land restoration on a global scale. This study evaluated the effects of biochar (1% Bc), compost (1% Co), and their blends (0.5% Bc + 0.5% Co and 1% Bc

High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands

open access: yesLaser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
E/O modulators typically face a trade‐off between bandwidth and modulation efficiency. An integrated E/O modulator is presented that simultaneously achieves wideband, large bandwidth, and high modulation efficiency operation by embedding a partially overlapped double‐layer graphene on a compact silicon slot‐waveguide microring resonator.

Femtosecond‐Laser‐Inscribed Cladding Fiber Bragg Gratings: Architectures, Design Trade‐Offs and Future Sensing Opportunities

open access: yesLaser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
Femtosecond‐laser inscription enables precise positioning of fiber Bragg gratings within the cladding, introducing new spatial and modal design freedoms. Auxiliary‐waveguide, near‐core evanescent‐field, and direct cladding‐mode‐excitation architectures provide complementary pathways toward multiparameter, vector, distributed, and environmentally ...

A Review of Robotic Surgery: Engineering Considerations and Future Directions From Surgeons' Perspectives

open access: yesThe International Journal of Medical Robotics and Computer Assisted Surgery, Volume 22, Issue 5, October 2026.
ABSTRACT Introduction Since its initial inception, robotic‐assisted minimally invasive surgery (RAMIS) is continually being applied to a wider array of procedures. However, there are significant limitations in current surgical subsystems, including a large learning curve, lack of effective haptic feedback, decreased surgical intuition, and decreased ...

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
