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.

Stable wideband ac–dc converter

Review of Scientific Instruments, 1982
This paper describes improvements on a stable wideband ac–dc converter, which is basically composed of a dual junction field effect transistor and a low drift operational amplifier. This converter has a stable square-law transfer characteristic up to 200 MHz for 0–0.5 V output with a drift of less than 0.1 mV/h.

Single-phase AC/DC integrated PWM converter

INTELEC. Twenty-Second International Telecommunications Energy Conference (Cat. No.00CH37131), 2002
The paper proposes a new topology of a boost type AC/DC PWM converter featuring high power factor, full control of the output DC voltage and high-frequency line filter inductor and insulation transformer. Its main advantage is the complete integration of a rectifier and an inverter stage, so that a compact converter with only four IGBTs and six diodes ...
