Nucleosome Array Deformation in Chromatin is Sustained by Bending, Twisting and Kinking of Linker DNA

Fabrizio Cleri, Stefano Giordano, Ralf Blossey

Chromatin in the nucleus undergoes mechanical stresses from different sources during the various stages of cell life. Here a trinucleosome array is used as the minimal model to study the mechanical response to applied stress at the molecular level. By using large-scale, all-atom steered-molecular...

Theoretical Investigation of Capture, Collection, and Targeted Transfer of Underwater Gas Bubbles Using Janus‐Faced Carbon Cloth

Haniyeh Tahzibi, Saeid Azizian, Sabine Szunerits, Rabah Boukherroub

Recently, a straightforward method for the preparation of a Janus carbon cloth (Janus-CC) is reported. The method relies on polydimethylsiloxane (PDMS) coating, followed by flame exposure of one face of the PDMS-coated CC. The nonexposed to the flame face of the Janus-CC is superhydrophobic, while...
