one of the important bottle-necks in production of microalgae based biodiesel is thelack of an efficient method for harvesting of microalgae from the culture medium. in thisstudy, the electroflocculation method was developed for harvesting of microalgaedunaliella cells from culture medium. the effect of several parameters such as thecurrent density, electrical conductivity of culture medium, ti...

The efficient water harvesting from air-laden moisture has been a subject of great interest to address world-wide water shortage issues. Recently, it has been shown that tailoring surface wettability can enhance the moisture harvesting performance. However, depending on the harvesting condition, a different conclusion has often been reported and it remains unclear what type of surface wettabili...

The main concern of an olive grower is primarily to achieve more income and profits. A harvesting method having higher efficiency and better fruit and oil quality, but a higher operation cost leads to a lower benefit. A study was carried out to evaluate the techno-economic performances of Trunk Shaker (TS) and Mechanical Harvest Aid (MHA) shaker for harvesting the yellow and Manzanilla olive cu...

The effects of changes in cellular characteristics and dissolved organic matter (DOM) on dissolved air flotation (DAF) harvesting of Chlorella zofingiensis at the different growth phases were studied. Harvesting efficiency increased with Al(3+) dosage and reached more than 90%, regardless of growth phases. In the absence of DOM, the ratio of Al(3+) dosage to surface functional group concentrati...

Energy harvesting, which offers a never-ending energy supply, has emerged as a prominent technology to prolong the lifetime and reduce costs for the battery-powered wireless sensor networks. However, how to improve the energy efficiency while guaranteeing the quality of service (QoS) for energy harvesting based wireless sensor networks is still an open problem. In this paper, we develop statist...

Fucoxanthin is a carotenoid that is mainly found in light-harvesting complexes from brown algae and diatoms. Due to the presence of a carbonyl group attached to polyene chains in polar environments, excitation produces an excited intra-molecular charge transfer. This intra-molecular charge transfer state plays a key role in the highly efficient (∼95%) energy-transfer from fucoxanthin to chlorop...

It is predicted that energy consumption will increase by 56% between year 2010 and 2040. To cope with this upcoming energy demand, innovative technologies have been developed in recent decades to harvest energy from the environment such as wind, solar, tide and vibration. Harvesting energy from structural vibration presents two major challenges: efficiency and vibration control. In particular, ...

ground state geometries have been computed using density functional theory (dft) at b3lyp/6-31g(d,p) level of theory. the excitation energies and spectroscopic parameters have been computed using long range corrected (lc) hybrid functional by time dependent density functional theory (tddft) with lc-blyp level of theory. the polarizable continuum model (pcm) has been used for evaluating bulk sol...
