Nonmetallic plasmonic Al-doped W18O49 drives pure CO production from formic acid dehydration

As a vital industrial feedstock, carbon monoxide (CO) is widely employed in pharmaceutical, electronic and fine chemical synthesis, yet its efficient production in high purity remains challenging. Here we report a solar-driven route to high-purity CO from formic acid using a nonm...

Spatiotemporal Synergetic Control of Roof Stability in Longwall Paste Backfill Mining: An Analytical Model Considering Time-Varying Backfill Characteristics

To address the difficulty of roof control in longwall paste backfill mining and to better capture the backfill’s ‘sequential bearing’ effect, this study proposes an elastic foundation beam model. Based on the Gaohe Coal Mine, the “coal-support-backfill” model incorporates the tim...
