Exceptional Thermal Conductivity in Printed Dielectrics through Compositional and Microstructural Design

open access: yesAdvanced Materials, EarlyView.
A multi‐generational compositional design creates a printable low‐loss dielectric composite that achieves over 16 W m−1 K−1. This breakthrough is enabled by thermal post‐processing, which promotes templated crystallization in a polymer matrix from surface‐modified particles, creating a “hetero‐percolated network.” The resulting material is three ...

Mathematical modelling for optimized control of Moscow's sewer network

open access: yesApplied Mathematical Modelling, 1999
Abstract An algorithm for the optimized control of a branching urban head-and-gravity sewer network is proposed. The control consists in redistribution of the sewage flows between the network structural components. The algorithm is based on a mathematical model and presupposes the use of a computer.
