Dark Blue

Poly(3,4-ethylenedi-oxythiophene) (PEDOT) derivatives conducting polymers are known for their great electrochromic (EC) properties offering a reversible blue switch under an applied voltage. Characterizations of symmetrical EC devices, built on combinations of PEDOT thin films, deposited with a bar coater from commercial inks, and separated by a lithium-based ionic membrane, show highest performance for 800 nm thickness. Tuning of the color is further achieved by mixing the PEDOT film with oxides. Taking, in particular, the example of optically inactive iron oxide Fe2O3, a dark blue to reddish switch, of which intensity depends on the oxide content, is reported. Careful evaluation of the chromaticity parameters L*, a*, and b*, with oxidizing/reducing potentials, evidences a possible monitoring of the bluish tint.

Control Framework

This paper proposes and experimentally validates a hierarchical control framework for fluid flow systems performing thermal management in mobile energy platforms. A graph-based modeling approach derived from the conservation of mass and energy inherently captures coupling within and between physical domains. Hydrodynamic and thermodynamic graph-based models are experimentally validated on a thermal-fluid testbed. A scalable hierarchical control framework using the graph-based models with model predictive control (MPC) is proposed to manage the multidomain and multi-timescale dynamics of thermal management systems. The proposed hierarchical control framework is compared to decentralized and centralized benchmark controllers and found to maintain temperature bounds better while using less electrical energy for actuation.

The Future

The goal of power sector in Nigeria is to efficiently and reliably transmit electrical power to all parts of the country which are made up of thirty-six states of the federation and the federal capital territory. The constituents of electrical power system are the generation, transmission, distribution and the utilization of electrical energy. There is gross power imbalance between the generation and the required power demand which has culminated into a defective economy in the last three decades. This paper therefore examines the power imbalance between the generation and power demand by the consumers and therefore stresses the need to harness the opportunity of renewable energy generation close to the gap between the power generation and power demand. This will help in transmitting and distributing efficient, effective, reliable power to consumers and improve both human and capital development. The availability of renewable energy sources such as sun, wind and small hydro power will be explored for the future of power generation in the country to fill in the gap between power generation and demand in Nigeria
