Spin- and valley-dependent transports through ferromagnetic 8-pmmn borophene monolayer
Fatemeh Imanian Mofrad Bidgoli, Hossein Nikoofard, Narges Nikoofard +1
We study spin and valley-dependent transport properties in an n-p-n junction of 8-pmmn borophene monolayer. An external gate voltage and exchange magnetic field, induced by the pro…
Dynamics of Polymer Ejection from a Nano-sphere
Farzaneh Moazemi, Samaneh Ghanbari-Kashan, Narges Nikoofard
Polymer ejection from nano-confinement has been of interest due to its relation to various fundamental sciences and applications. However, the ejection dynamics of a polymer with d…
Topology Sorting and Characterization of Folded Polymers Using Nano-pores
Narges Nikoofard, Alireza Mashaghi
Here we report on the translocation of folded polymers through nano-pores using molecular dynamic simulations. Two cases are studied; one in which a folded molecule unfolds upon pa…
Flexible polymer confined inside a cone-shaped nano-channel
Narges Nikoofard, Hossein Fazli
Nano-scale confinement of polymer in cone-shaped geometries occurs in many experimental situations. A flexible polymer confined in a cone-shaped nano-channel is studied theoretical…
Accuracy of the blob model for single flexible polymers inside nanoslits that are a few monomer sizes wide
Narges Nikoofard, S. Mohammad Hoseinpoor, Mostafa Zahedifar
The de Gennes' blob model is extensively used in different problems of polymer physics. This model is theoretically applicable when the number of monomers inside each blob is large…
Distribution of counterions and interaction between two similarly charged dielectric slabs: Roles of charge discreteness and dielectric inhomogeneity
Weria Pezeshkian, Narges Nikoofard, Davood Norouzi +2
The distribution of counterions and the electrostatic interaction between two similarly charged dielectric slabs is studied in the strong coupling limit. Dielectric inhomogeneities…
Directed translocation of a flexible polymer through a cone-shaped channel
Narges Nikoofard, Hamidreza Khalilian, Hossein Fazli
Entropy-driven directed translocation of a flexible polymer through a cone-shaped channel is studied theoretically and using computer simulation. For a given length of the channel,…
Electric-field-driven polymer entry into asymmetric nanoscale channels
Narges Nikoofard, Hossein Fazli
The electric-field-driven entry process of flexible charged polymers such as single stranded DNA (ssDNA) into asymmetric nanoscale channels such as alpha-hemolysin protein channel…
Free Energy Barrier for Electric Field Driven Polymer Entry into Nanoscale Channels
Narges Nikoofard, Hossein Fazli
Free energy barrier for entry of a charged polymer into a nanoscale channel by a driving electric field is studied theoretically and using molecular dynamics simulations. Dependenc…
