Biochar as a Strategy to Mitigate Greenhouse Gases in Degraded Drylands of the Brazilian Semiarid Region: Carbon Stocks and CO2 Fluxes

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 6, Page 1014-1026, December 2025.
This study evaluated the effects of pyrolytic biochars derived from co‐pyrolyzed sewage sludge and cashew residues on total organic carbon (TOC) recovery and CO2 emissions in degraded soils under greenhouse conditions. Biochar applications (5 to 40 Mg ha−1) enhanced soil carbon stocks and variably influenced CO2 fluxes over time.

Nonlinear Distortion Equalization in Multi‐Span Optical Links Via a Feed‐Forward Photonic Neural Network

Laser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.
A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.
