A new design strategy for the development of fluorescent turn-on chemodosimeters toward OCl− was proposed by removal, but not general inhibition, CN isomerization. Accordingly, Flu-1 prepared, which, as shown in picture, exhibited off–on response OCl−, sensitively and selectively.
An enhanced DC-DC converter is proposed in this paper, based on the combination of Cuk and SEPIC converters, which well-suited for solar photovoltaic (PV) applications. The uses only one switch (which ground-referenced, so simple gate drive circuitry may be used), yet provides dual outputs form a bipolar DC bus. output from able to send power grid via any inverter with unipolar or input, leakage currents can eliminated if latter type used without using lossy capacitors load current loop....
Thin-film composite reverse osmosis membranes have remained the gold standard technology for desalination and water purification nearly half a century. Polyamide films offer excellent permeability salt rejection but also suffer from poor chlorine resistance, high fouling propensity, low boron rejection. We addressed these issues by molecularly designing polyester thin-film membrane using co-solvent-assisted interfacial polymerization to react 3,5-dihydroxy-4-methylbenzoic acid with trimesoyl...
The brushless doubly fed induction generator (BDFIG) shows commercial promise for wind power generation due to its lower cost and higher reliability when compared with the conventional DFIG. In most recent grid codes, generators are required be able ride through a low-voltage fault meet reactive current demand from grid. A ride-through (LVRT) capability is therefore important which integrated into this paper, authors propose control strategy enabling BDFIG successfully symmetrical voltage...
Extensive use of amateur drones (ADrs) poses a threat to the public safety due their possible misuse. Hence, surveillance (SDrs) are utilized detect and eliminate potential threats.

To this end, we conceptualize Energy Neutral Internet Drones (enIoD) enable enhanced connectivity between by overcoming energy limitations for autonomous continuous operation. Power provisioning with...
This article presents an analysis and design of a new boost type six-switch five-level (5L) active neutral point clamped (ANPC) inverter based on switched/flying capacitor technique with self-voltage balancing. Compared to major conventional 5L topologies, such as clamped, flying capacitor, cascaded H-bridge, ANPC the topology reduces dc-link voltage requirement by 50%. Whilst reducing requirement, number size passive components are also reduced without compromising reactive power...
