We investigate the design of future energy storage systems by exploring one particular solution, in simulations. We use Lithium-ion batteries for storage, a dual active bridge (DAB) for DC to DC conversion and a synchronverter to transfer energy from the DC bus to the utility grid. We show how some recent improvements to the synchronverter algorithm can be combined with a battery management alg...

Herein we report the synthesis and structural characterization of three new europium containing coordination polymers: [Eu(terpy)(2,6-ndc) 1.5 ]·H 2 O (Linus Pauling (LP) 1), [Eu(terpy)(1,4-ndc)(1,4-Hndc)] ( LP- 2), [Eu(phen)(2,6-ndc) ]·DMF 3).

Biomass is identified as one of the major renewable energy sources for electrical power generation. Heavy duty gas turbine engines are preferred for clean and efficient power generation. An extensive literature survey reveals that the governor droop setting of the heavy duty gas turbines varies from 2 percentage to 10 percentage. But it needs to be optimized for analyzing the dynamic response o...

Three indium-oxide organic frameworks, In(2)O(1,3-BDC)(2), 1; In(OH)(2,6-NDC)(H(2)O), 2; and In(OH)(2,7-NDC)(H(2)O), 3 (BDC = benzene dicarboxylic acid and NDC = naphthalene dicarboxylic acid), were synthesized and characterized by thermogravimetric analysis, infrared spectroscopy, and single-crystal X-ray diffraction. Previously, we reported the structure of In(OH)(1,4-BDC).(0.75H(2)BDC), 0, w...

In this paper, several commonly used gage repeatability and reproducibility (R&R) acceptance criteria are discussed. The number of distinct categories (ndc) is equivalent to an acceptance criterion based on another standard metric, the ratio of the estimated measurement system standard deviation to the estimated overall standard deviation of the measurements. This implies that the criterion bas...

In the title compound, [Mn(2)(C(12)H(6)O(4))(2)(C(10)H(14)N(4))(H(2)O)](n) or [Mn(2)(1,4-ndc)(2)(L)(H(2)O)](n), where 1,4-ndc is naphthalene-1,4-dicarboxyl-ate and L is 1,1'-(butane-1,4-di-yl)diimidazole, the coordination polyhedron around each Mn(II) atom is distorted octa-hedral. The water mol-ecule and the L ligand are situated across a twofold rotation axis. The Mn(II) atoms are bridged by ...

The negative differential capacitance (NDC) effect is observed on a titanium-oxide-silicon structure, formed on n-type silicon with embedded germanium quantum dots (QDs). The Ge QDs were grown by an Sb-mediated technique. The NDC effect was observed for temperatures below 200 K. We found that approximately six to eight electrons can be trapped in the valence band states of Ge QDs. We explain th...

Efficiency droop in GaN-based light emitting diodes (LEDs) under high injection current density perplexes the development of high-power solid-state lighting. Although the relevant study has lasted for about 10 years, its mechanism is still not thoroughly clear, and consequently its solution is also unsatisfactory up to now. Some emerging applications, e.g., high-speed visible light communicatio...
