with the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. the novel concept of photovoltaic powered ...

In anticipation of a new era of synchrotron radiation sources based on Energy Recovery Linac techniques we designed, built and tested a short undulator magnet prototype whose features make optimum use of the unique conditions expected in these facilities. The prototype has pure permanent magnet (PPM) structure with 24mm period, 5mm diameter round gap and is 30cm long. In comparison with convent...

In this paper, we present the design and experimental evaluation of an 8-bit energy-recovery multiplier with built-in self-test logic and an internal single-phase sinusoidal power-clock generator. Both the multiplier and the built-in self-test have been designed in SCAL-D, a true single-phase adiabatic logic family. Fabricated in a 0.5m standard n-well CMOS process, the chip has an active area ...

A new Quasi-Static Energy Recovery Logic family (QSERL) using the principle of adiabatic switching is proposed in this paper. Most of the previously proposed adiabatic logic are dynamic and require complex clocking schemes. The proposed Quasi-Static energy recovery logic uses two complementary sinusoidal supply clocks and resembles behaviors of static CMOS. Thus, switching activity is signiican...

This paper presents an overview of existing and emerging technologies on electron sources that can service various energy recovering linacs under consideration. Photocathodes that can deliver average currents from 1mA to 1A, the pros and cons associated with these cathodes are addressed. Status of emerging technologies such as secondary emitters, cesiated dispenser cathodes, field and photon as...

Power consumption is an increasing concern in VLSI circuits. To meet the energy requirements new logic circuits have been developed alternatively to standard CMOS. The so-called adiabatic families reduce energy consumption due to the use of a pulsed power supply. A slowly varying voltage source requires less energy to charge a capacitance if its period is longer than the time constant of the ch...

By harnessing the oxidative power of microorganisms, energy can be recovered from reservoirs of less-concentrated organic matter, such as marine sediment, wastewater, and waste biomass. Left unmanaged, these reservoirs can become eutrophic dead zones and sites of greenhouse gas generation. Here, we introduce a unique means of energy recovery from these reservoirs-a microbial battery (MB) consis...
