Electrochemical reaction in single layer MoS2: nanopores opened atom by atom
J. Feng, K. Liu, M. Graf +8
Ultrathin nanopore membranes based on 2D materials have demonstrated ultimate resolution toward DNA sequencing. Among them, molybdenum disulphide (MoS2) shows long-term stability a…
Intermediate DNA at low added salt: DNA bubbles slow the diffusion of short DNA fragments
Tomislav Vuletic, Sanja Dolanski Babic, Ticijana Ban +3
We report a study of DNA (150 bp fragments) conformations in very low added salt mM, across wide DNA concentration range ~mM (bp). We found an intermedi…
Manning free counterions fraction for a rod-like polyion - short DNA fragments in very low salt
Tomislav Vuletic, Sanja Dolanski Babic, Danijel Grgicin +4
We quantified the Manning free (uncondensed) counterions fraction for dilute solutions of rod-like polyions - 150bp DNA fragments, in very low salt mM. Conductivity meas…
Crossover from one-dimensional copper-oxygen chains to two-dimensional ladders charge transport in (La,Y)y(Sr,Ca)14-yCu24O41
T. Ivek, T. Vuletic, B. Korin-Hamzic +8
The charge transport in the copper-oxygen chain/ladder layers of (La,Y)y(Sr,Ca)14-yCu24O41 is investigated along two crystallographic directions in the temperature range from 50 K…
Short-fragment Na-DNA dilute aqueous solutions: fundamental length scales and screening
S. Tomic, S. Dolanski Babic, T. Ivek +4
Dielectric spectroscopy is used to investigate fundamental length scales of 146 bp short-fragment (nucleosomal) dilute Na-DNA solutions. Two relaxation modes are detected: the high…
Collective Charge Excitations below the Metal-to-Insulator Transition in BaVS3
T. Ivek, T. Vuletic, S. Tomic +3
The charge response in the barium vanadium sulfide (BaVS3) single crystals is characterized by dc resistivity and low frequency dielectric spectroscopy. A broad relaxation mode in…
Dielectric relaxation of DNA aqueous solutions
S. Tomic, S. Dolanski Babic, T. Vuletic +4
We report on a detailed characterization of complex dielectric response of Na-DNA aqueous solutions by means of low-frequency dielectric spectroscopy (40 Hz - 110 MHz). Results rev…
Coexistence of Superconductivity and Spin Density Wave orderings in the organic superconductor (TMTSF)_2PF_6
T. Vuletic, P. Auban-Senzier, C. Pasquier +4
The phase diagram of the organic superconductor (TMTSF)_2PF_6 has been revisited using transport measurements with an improved control of the applied pressure. We have found a 0.8…
