Interdigitated Horizontal Electrodes for Organic Solar Cells

IEEE Access, 2018
We first introduce a new electrode structure for organic solar cells (OSCs), the so-called interdigitated horizontal electrode (IHE), in which an electron-collecting electrode and a hole-collecting electrode are horizontally separated.

Harvesting of microalgae by bio-flocculation [PDF]

, 2010
The high-energy input for harvesting biomass makes current commercial microalgal biodiesel production economically unfeasible. A novel harvesting method is presented as a cost and energy efficient alternative: the bio-flocculation by using one ...

Energy harvesting from vibrations with a nonlinear oscillator

, 2009
In this paper we present a nonlinear electromagnetic energy harvesting device that has a broadly resonant response. The nonlinearity is generated by a particular arrangement of magnets in conjunction with an iron-cored stator.

To Harvest or Not to Harvest: Mapping and Decision-Making for a Selective Table Grape Harvesting Robot

IEEE Robotics and Automation Letters
This letter focuses on robotic harvesting of delicate crops such as table grapes, featuring selective harvesting based on individual product properties. The robot detects grape bunches and estimates their positions and quality attributes. However, sensor limitations and occlusions affect data completeness and accuracy, reducing the cost-effectiveness ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
