Condensation of phenol and acetone on a modified macroreticular ion exchange resin catalyst

Baohe WANG, Lili WANG, Jing ZHU, Shuang CHEN, Hao SUN

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 2,   Pages 218-225 doi: 10.1007/s11705-013-1330-9

Abstract: Macroreticular ion exchange resin catalysts were prepared by suspension polymerization, and then modified by alkylmercaptoamines. The modified catalysts were characterized by N adsorption/desorption measurements, scanning electron microscopy and differential scanning calorimetry. Key factors such as the mercaptan content, the degree of crosslinking and the structures of the promoters were investigated for the synthesis of Bisphenol A (BPA). At optimal conditions, the macroreticular ion exchange resin catalysts modified by alkylmercaptoamines showed high catalytic activity and selectivity for BPA synthesis.

Topology optimization based on reduction methods with applications to multiscale design and additive manufacturing

Emmanuel TROMME, Atsushi KAWAMOTO, James K. GUEST

Frontiers of Mechanical Engineering 2020, Volume 15, Issue 1,   Pages 151-165 doi: 10.1007/s11465-019-0564-8

Abstract: Advanced manufacturing processes such as additive manufacturing offer now the capability to control material placement at unprecedented length scales and thereby dramatically open up the design space. This includes the considerations of new component topologies as well as the architecture of material within a topology offering new paths to creating lighter and more efficient structures. Topology optimization is an ideal tool for navigating this multiscale design problem and leveraging the capabilities of advanced manufacturing technologies. However, the resulting design problem is computationally challenging as very fine discretizations are needed to capture all micro-structural details. In this paper, a method based on reduction techniques is proposed to perform efficiently topology optimization at multiple scales. This method solves the design problem without length scale separation, i.e., without iterating between the two scales. Ergo, connectivity between space-varying micro-structures is naturally ensured. Several design problems for various types of micro-structural periodicity are performed to illustrate the method, including applications to infill patterns in additive manufacturing.
