Lime mortars have played an important role in constructing ancient Chinese masonry structures, including city walls, buildings, and tombs. A tomb built with lime mortars and stones belonging a Ming high‐ranking official, Xu Jie, was discovered in Huzhou City of China. Eight different samples from Xu Jie’s tomb, representing four types of lime‐mortar‐based materials: joint mortar between stone bricks,...
Three polysiloxane/epoxy hybrids obtained by evolving cage- or linear-structured polysiloxane into poly glycidyl methacrylate (PGMA) matrix are compared used as coatings. One is the cage-structured hybrid of P(GMA/MA-POSS) copolymer obtained by GMA and methacrylisobutyl polyhedral oligomeric silsesquioxane (MA-POSS) via free radical polymerization, the other two are PGMA/NH2-POSS and PGMA/NH2-PDMS...
In this paper, we present the design of a low-power, high power supply rejection (PSR) voltage regulating circuit in a 0.35μm standard CMOS process. A CMOS full-wave bridge rectifier is designed to generate an unregulated DC voltage. A low dropout (LDO) series voltage regulator converts the unregulated voltage to a stable and clean DC supply voltage. A self-biased wide range and high power supply...
With the rapid development of CMOS-compatible MEMS technology, it has been used to improve the performance of monolithic integrated RF circuits. To take advantages of the MEMS devices in RF circuits, accurate models are needed, with the considerations of important effects that impact the electrical behavior of the devices. In this paper, we explore the modeling methodology for CMOS-compatible MEMS...
