Optimized control strategy for single-phase multilevel cascaded converter in a distributed PV-BESS system

The paper focuses on the energy management of a single-phase PV-BESS hybrid distributed system sized for residential applications, using a CHB converter topology as grid interface. The CHB is driven with a hierarchical energy management architecture, with ...

Evidence that the Lunar Cycle Influences Human Sleep

Endogenous rhythms of circalunar periodicity (similar to 29.5 days) and their underlying molecular and genetic basis have been demonstrated in a number of marine species [1, 2]. In contrast, there is a great deal of folklore but no consistent association o ...

Application of Cu(II) and Zn(II) coproporphyrins as sensitizers for thin film dye sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Mingkui Wang, Pascal Comte, Joël Teuscher, Davide Di Censo, Leila Alibabaei

We synthesized the Cu(II) and Zn(II) complexes of the 2,7,12,17-tetrapropionic acid of 3,8,13,18-tetramethyl-21H,23H porphyrin (coproporphyrin-I) and successfully employed them as sensitizers in dye-sensitized solar cells. Copper(II) coproporphyrin-I exhib ...

Employ a bisthienothiophene linker to construct an organic chromophore for efficient and stable dye-sensitized solar cells

Shaik Mohammed Zakeeruddin, Peng Wang, Yu Bai, Sophie Wenger

We employed the bisthienothiophene conjugated linker along with a hydrophobic triphenylamine electron-donor and a hydrophilic cyanoacrylic acid electron-acceptor to construct a high molar extinction coefficient organic photosensitizer, exhibiting a power c ...

Multiple-resonance spectroscopy of high vibrational levels in water and methanol

Pavlo Maksyutenko

We have measured the rovibrational levels in the electronic ground state of the water molecule at the previously inaccessible energies above 26000 cm-1. The use of laser double-resonance overtone excitation combined with laser-induced fluorescence (LIF) ph ...

Conformational dependence of intramolecular vibrational redistribution in methanol

Thomas Rizzo, Pavlo Maksyutenko

Previous state-selected spectra of methanol in the 5ν1 OH stretch overtone region [O. V. Boyarkin, T. R. Rizzo, and D. S. Perry, J. Chem. Phys. 110 (23), 11346 (1999)] revealed structure indicating intramolecular vibrational redistribution (IVR) on three t ...
