Low-heat Solid-state Lasers
The paper discusses the processes that determine the parasitic heat generation and its distribution in the solid-state laser materials. It is inferred that the balance between the laser emission and heat generation is determined by the characteristics of the pumping system and by the partial efficiencies of the various steps of the flow of excitation between the energy levels of the laser mater...
متن کاملImproving System Performance Using Solid-State Disk
Solid-state disk (SSD) provides 100 times the I/O performance of hard drives (HDDs) but at 100 times the cost per gigabyte or more. Compared with other techniques such as in-memory databases and database tuning, SSD can be a cost-effective solution to improving the performance of I/O-bound applications. But in order to achieve the proper balance between cost and performance, it is necessary to ...
متن کاملHeat-accelerated degradation of solid-state andrographolide.
The stability of andrographolide, the major active diterpene lactone from Andrographis paniculata (BURM. f.) WALL. ex NEES., was determined to show that, while crystalline andrographolide was highly stable even at 70 degrees C (75% relative humidity) over a period of 3 months, its amorphous phase degraded promptly. Heat-accelerated conditions revealed second-order kinetics of the decomposition ...
متن کاملHeat-Assisted Multiferroic Solid-State Memory
A heat-assisted multiferroic solid-state memory design is proposed and analysed, based on a PbNbZrSnTiO₃ antiferroelectric layer and Ni81Fe19 magnetic free layer. Information is stored as magnetisation direction in the free layer of a magnetic tunnel junction element. The bit writing process is contactless and relies on triggering thermally activated magnetisation switching of the free layer to...
متن کاملMechanothermal Solid-state Synthesis of Cobalt(II) Ferrite and Determination of its Heat Capacity by MTDSC
Cobalt ferrite (CoFe2O4) has been synthesized by a solid-state mechanothermal process, and its molar heat capacity has been determined. A stoichiometric mixture of CoC2O4 · 2H2O and FeC2O4 · 2H2O was subjected to a combination of mechanical activation (by high-energy milling) and thermal activation (by annealing at temperatures between 300 and 700 ◦C). The process was followed by thermogravimet...
