The Front Cover illustrates a schematic representation of the mechanical parameters involved in the mechanocatalytic depolymerization of lignocellulosic materials in a ball mill. Owing to the circular jar movement, a ball follows a defined pathway through the milling vial, which allows the estimation of its velocity and, hence, the determination of the kinetic energy transferred to the substrate. This kinematic modeling approach results in an ultimate equation that is primarily dependent on the mill geometry and characteristics, number of the balls, milling time, and rotational speed. In this work, we demonstrate the existence of correlations between the apparent kinetic energy transfer and the yield of water‐soluble products (oligosaccharides and lignin oligomers) depending on the type of (ligno)cellulose substrate employed. More information can be found in the Full Paper by Kessler et al. on page 552 in Issue 3, 2018 (DOI: 10.1002/cssc.201702060).

封面：α-纤维素和比奇伍德的机械催化解聚的运动学模型（ChemSusChem 3/2018）

封面图1示出了在球磨机中木质纤维素材料的机械催化解聚中涉及的机械参数的示意图。由于圆形广口瓶的运动，球沿着确定的路径通过研磨瓶，从而可以估计其速度，从而确定转移到基材上的动能。这种运动学建模方法得出了最终方程，该方程主要取决于磨机的几何形状和特性，球的数量，磨机的时间和转速。在这项工作中，我们证明了视动能转移与水溶性产品（寡糖和木质素低聚物）的产量之间存在相关性，具体取决于所用（木质素）纤维素底物的类型。可以在Kessler等人的论文全文中找到更多信息。上2018年第3期中的第552页（DOI：10.1002 / cssc.201702060）。
