Matsumoto K, Takayanagi M, Suzuki Y, Koga N, Nagaoka M
J Comput Chem . 2018 Oct; 40(2):421-429. PMID: 30351517
We have realized the microscopic simulation of olefin polymerization, that is, the simulation of the catalytic polymerization (CP) reaction system composed of (pyridylamido)hafnium(IV) complex as the catalyst. For this purpose,...

Le Ouay B, Watanabe C, Mochizuki S, Takayanagi M, Nagaoka M, Kitao T, et al.
Nat Commun . 2018 Sep; 9(1):3635. PMID: 30194388
Separation of high-molecular-weight polymers differing just by one monomeric unit remains a challenging task. Here, we describe a protocol using metal-organic frameworks (MOFs) for the efficient separation and purification of...

Saha S, Takayanagi M, Matsumoto K, Karakkadparambil Sankaran S, Tanaka Y, Koga N, et al.
J Phys Chem A . 2018 Feb; 122(8):2198-2208. PMID: 29394059
The possibility of coexistence of multiple isomers for zirconium bis(phenoxy-imine) catalyst has been systematically studied by computational approaches. The energetics among the five different isomers of neutral Zr-catalyst have been...

Nat Commun . 2018 Jan; 9(1):329. PMID: 29362404
The design of monomer sequences in polymers has been a challenging research subject, especially in making vinyl copolymers by free-radical polymerization. Here, we report a strategy to obtain sequence-regulated vinyl...

Takayanagi M, Ito S, Matsumoto K, Nagaoka M
J Phys Chem B . 2016 Jul; 120(29):7174-81. PMID: 27376786
Ring-opening polymerization of lactones initiated by cyclodextrins has been reported as a promising polymer synthetic method. To investigate the unknown molecular level mechanism of the initiation reaction, we executed molecular...

Kurisaki I, Takayanagi M, Nagaoka M
J Phys Chem B . 2016 May; 120(20):4540-7. PMID: 27164318
Thrombin has been studied as a paradigmatic protein of Na(+)-activated allosteric enzymes. Earlier structural studies suggest that Na(+)-binding promotes the thrombin-substrate association reaction. However, it is still elusive because (1)...

Kurisaki I, Barberot C, Takayanagi M, Nagaoka M
J Phys Chem B . 2015 Dec; 119(52):15807-12. PMID: 26634958
Upon protein-substrate association reaction, dewetting of the substrate-binding pocket is one of the rate-limiting processes. However, understanding the microscopic mechanism still remains challenging because of practical limitations of experimental methodologies....
