III The use ofdiode lasers instead ofHashlamps as optical pump sources for solid state lasers offers significant advantages such as higher efficiency and longer lifetime. We have demonstrated three novel lasers based on this technology. The first is a zig-zag slab laser pumped by hybrid planar microchannel-cooled diode arrays that allow high-repetition-rate operation in a pulsed mode. The secon...

Solid-state drives (SSDs) are a potentially revolutionary new storage technology, but it is not clear that current generation drives are inherently superior to hard disks. In order to understand the performance of these new technologies, we measure two commercial SSDs, one from Intel, the other from Kingston, on a workload of 4K writes to randomized addresses across the entire address space of ...

Dramatic improvement in the efficiency of inorganic and organic light emitting diodes (LEDs and OLEDs) within the last decade has made these devices viable future energy efficient replacements for current light sources. However, both technologies must overcome major technical barriers, requiring significant advances in material science, before this goal can be achieved. Attention will be given ...

631 Photonic technologies are becoming increasingly prevalent in our daily lives. After decades of rapid advances, light sources — especially lasers and light-emitting diodes — have become high-performance, yet low-cost and reliable components, driving the Internet and lighting cities. A new frontier of research is the development of non-classical light sources: sources that produce streams of ...

A laboratory-testable, solid-state Maxwell demon is proposed that utilizes the electric field energy of an open-gap p-n junction. Numerical results from a commercial semiconductor device simulator (Silvaco International – Atlas) verify primary results from a 1-D analytic model. Present day fabrication techniques appear adequate for laboratory tests of principle.

A Pulsed Power System is characterized by its energy storage system, the energy can be released in the form of a high power pulse to the load, by means of a switching device. The energy storage is usually either of an inductive or a capacitive nature. The limiting device in a Pulsed Power System is often the switch, which limits the pulse peak power and the repetition rate. The conventional app...

The purpose of this investigation is to characterize nevirapine from commercial samples and samples crystallized from different solvents under various conditions. The solid-state behavior of nevirapine samples was investigated using a variety of complementary techniques such as microscopy (optical, polarized, hot stage microscopy), differential scanning calorimeter, thermogravimetric analysis, ...

The idea of engineering cooling systems and generators based on thermal transformations and energy conversion in solids has been exciting scientific minds already for several decades. In recent years, a possibility of coolers production based on the electrocaloric effect (ECE) began to become of special interest [1]. This interest is related to the substantial progress made in investigations of...

Following a brief historical review of solid-state photochemistry current research is discussed under four parallel headings: first, analysis of the topochemical postulate according to which the course of the solid-state reaction and the stereochemistry of the photodimer (if any) can be predicted from the configuration and nearest-neighbour geometry of closest monomer molecules in the crystal l...
