A Bibliometric‐Based Review of Biochar for Salt‐Affected Soil Restoration: Mapping Research Trends and Future Directions

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT In recent years, biochar has been studied for its range of applications. Recognized by the IPCC as a key Carbon Dioxide Removal (CDR) strategy, it also stands out as an important tool for reclaiming degraded lands, including vast global areas affected by salinity, such as those in China, India, and Australia.

Photons as Working Body for Photovoltaic Devices: Conversion of Photon to Electron from a Simplified Perspective

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 1, January 2026.
In this work two models to study the photovoltaic response of solar cells are reported. The first model considers the bandgap effect to quantify the conversion of photons into electrons that makes up the photocurrent in the maximum electrical output power condition. The second model quantifies photocurrent in the short circuit condition from the energy
