Permanent Deformation Characteristics of Beach Sand as a Subgrade Filler Integrating Dynamic Triaxial Testing and Machine Learning

Applied Research, Volume 5, Issue 5, October 2026.
Dynamic triaxial tests, field FBG monitoring, and machine‐learning analysis reveal that beach‐sand subgrade deformation is governed primarily by deviatoric stress and moisture. Fine sand deforms more than medium sand, while overload and wet‐side moisture deviation sharply amplify permanent deformation.

Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

Advanced Physics Research, Volume 5, Issue 10, October 2026.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...

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

ChemCatChem, 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

Land 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

Laser &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

Laser &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 ...
