    • Anomalously Rapid Tunneling: Charge Transport across Self-Assembled Monolayers of Oligo(ethylene glycol) 

      Baghbanzadeh, Mostafa; Bowers, Carleen M.; Rappoport, Dmitrij; ?aba, Tomasz; Yuan, Li; Kang, Kyungtae; Liao, Kung-Ching; Gonidec, Mathieu; Rothemund, Philipp Josef Michael; Cyganik, Piotr; Aspuru-Guzik, Alan; Whitesides, George McClelland (American Chemical Society (ACS), 2017)
      This paper describes charge transport by tunneling across self-assembled monolayers (SAMs) of thiol-terminated derivatives of oligo(ethylene glycol) (HS(CH2CH2O)nCH3; HS(EG)nCH3); these SAMs are positioned between gold ...

    • Autocatalytic, bistable, oscillatory networks of biologically relevant organic reactions 

      Semenov, Sergey N.; Kraft, Lewis J.; Ainla, Alar; Zhao, Mengxia; Baghbanzadeh, Mostafa; Campbell, Victoria; Kang, Kyungtae; Fox, Jerome; Whitesides, George McClelland (Springer Nature, 2016)
      Networks of organic chemical reactions are centrally important in life, and were likely to have played a central role in its origins. Network dynamics regulate cell division, circadian rhythms, nerve impulses, chemotaxis, ...

    • Characterizing the Metal–SAM Interface in Tunneling Junctions 

      Bowers, Carleen Morris; Liao, Kung-ching; Zaba, Tomasz; Rappoport, Dmitrij; Baghbanzadeh, Mostafa; Breiten, Benjamin; Krzykawska, Anna; Cyganik, Piotr; Whitesides, George McClelland (American Chemical Society (ACS), 2015)
      his paper investigates the influence of the interface between a gold or silver metal electrode and an n-alkyl SAM (supported on that electrode) on the rate of charge transport across junctions with structure Met(Au or ...

    • Charge Tunneling along Short Oligoglycine Chains 

      Baghbanzadeh, Mostafa; Bowers, Carleen Morris; Rappoport, Dmitrij; Zaba, Tomasz; Gonidec, Mathieu; Al-Sayah, Mohammad; Cyganik, Piotr; Aspuru-Guzik, Alan; Whitesides, George McClelland (Wiley-Blackwell, 2015)
      This work examines charge transport (CT) through self-assembled monolayers (SAMs) of oligoglycines having an N-terminal cysteine group that anchors the molecule to a gold substrate, and demonstrate that CT is rapid (relative ...

    • Interactions between Hofmeister Anions and the Binding Pocket of a Protein 

      Fox, Jerome Michael; Kang, Kyungtae; Sherman, Woody; Héroux, Annie; Sastry, G. Madhavi; Baghbanzadeh, Mostafa; Lockett, Matthew; Whitesides, George McClelland (American Chemical Society (ACS), 2015)
      This paper uses the binding pocket of human carbonic anhydrase II (HCAII, EC 4.2.1.1) as a tool to examine the properties of Hofmeister anions that determine (i) where, and how strongly, they associate with concavities on ...

    • Introducing Ionic and/or Hydrogen Bonds into the SAM//Ga 2 O 3 Top-Interface of Ag TS /S(CH 2 ) n T//Ga 2 O 3 /EGaIn Junctions 

      Bowers, Carleen Morris; Liao, Kung-ching; Yoon, Hyo Jae; Rappoport, Dmitrij; Baghbanzadeh, Mostafa; Simeone, Felice C.; Whitesides, George McClelland (American Chemical Society (ACS), 2014)
      Junctions with the structure AgTS/S(CH2)nT//Ga2O3/EGaIn (where S(CH2)nT is a self-assembled monolayer, SAM, of n-alkanethiolate bearing a terminal functional group T) make it possible to examine the response of rates of ...

    • Odd–Even Effects in Charge Transport across n -Alkanethiolate-Based SAMs 

      Baghbanzadeh, Mostafa; Simeone, Felice C.; Bowers, Carleen Morris; Liao, Kung-ching; Thuo, Martin; Baghbanzadeh, Mahdi; Miller, Michael S.; Carmichael, Tricia Breen; Whitesides, George McClelland (American Chemical Society (ACS), 2014)
      This paper compares rates of charge transport across self-assembled monolayers (SAMs) of n-alkanethiolates having odd and even numbers of carbon atoms (nodd and neven) using junctions with the structure MTS/SAM//Ga2O3/EGaIn ...

    • The Rate of Charge Tunneling Is Insensitive to Polar Terminal Groups in Self-Assembled Monolayers in Ag TS S(CH 2 ) n M(CH 2 ) m T//Ga 2 O 3 /EGaIn Junctions
