Study on the Adsorption Effect of Renewable Biochar Based on Energy Gain by Zhanghang Yang, Qixiang Xu, Ruiqin Zhang, Qianming Huang, Mingxin Liu

“…Since the crop-residual-derived charcoal could effectively restore the nutritional structure of the soil, which contributes to preventing the decrease in grain yield, and it is also a kind of renewable environment-friendly resource by itself, which could be used in control the pollution of heavy metal ions, it is expected that the crop-residual-derived charcoal will be a new adsorption material that could be used to control the heavy metal pollution in the future; the adsorption effect of biochar as new adsorption material on heavy metal ions has a distinct advantage over traditional adsorbent materials, and biochar is a renewable energy source, which is cheap and better for recycling resources.…”

Optical Properties of Er3+-Doped CdIn2O4 and CdIn2O4 Crystals by Tae Hwan Bang, Jong Wuk Kang, Jin Jeong

“…The photoluminescence (PL) spectra of CdIn2O4:Er3+ acquired in the wavelength range of 630–700 nm at 294 K showed peaks in the region of 651–686 nm and eight sharp emission peaks due to the Er3+ ions. These PL peaks were attributed to radiative transitions between the split electron energy levels of the Er3+ ions occupying the In3+ sites of the CdIn2O4 host lattice.…”
