Water-modulated conformational heterogeneity underlies multiple timescales of primary charge separation in photosystem II [PDF]
Nature CommunicationsThe kinetics of charge separation in Photosystem II, initiated within the reaction center, remain debated due to spectral congestion and overlapping timescales with energy transfer.

Charge-Based Separation of Micro- and Nanoparticles [PDF]
Micromachines, 2020 Deterministic Lateral Displacement (DLD) is a label-free particle sorting method that separates by size continuously and with high resolution. By combining DLD with electric fields (eDLD), we show separation of a variety of nano and micro-sized particles

Interfacial Charge-Transfer Transitions for Direct Charge-Separation Photovoltaics
Energies, 2020 Photoinduced charge separation (PCS) plays an essential role in various solar energy conversions such as photovoltaic conversion in solar cells. Usually, PCS in solar cells occurs stepwise via solar energy absorption by light absorbers (dyes, inorganic ...

An extended RΨm(2)(ΔS2) correlator for detecting and characterizing the Chiral Magnetic Wave
Physics Letters B, 2020 The extended RΨm(2)(ΔS2) correlator is presented and examined for its efficacy to detect and characterize the quadrupole charge separation (ΔS2) associated with the purported Chiral Magnetic Wave (CMW) produced in heavy-ion collisions.

Spontaneous Separation of Charged Grains [PDF]
Physical Review Letters, 2007 In 1867, Lord Kelvin described an experiment in which two streams of water droplets were connected so that each stream amplified the charge on the second stream [W. Thomson, Proc. R. Soc. London 16, 67 (1867)]. We present here a complementary effect in flowing grains that spontaneously separates similar and well-mixed grains into two charged streams of

The Charging Events in Contact-Separation Electrification [PDF]
Scientific Reports, 2018 AbstractContact electrification (CE)—charging of surfaces that are contacted and separated, is a common phenomenon, however it is not completely understood yet. Recent studies using surface imaging techniques and chemical analysis revealed a ‘spatial’ bipolar distribution of charges at the nano dimension, which made a paradigm shift in the field ...
