Journal ArticleDOI
Observation of fragile-to-strong dynamic crossover in protein hydration water.
TL;DR: It is demonstrated experimentally that this sudden switch in dynamic behavior of the hydration water on lysozyme occurs precisely at 220 K and can be described as a fragile-to-strong dynamic crossover.
Journal ArticleDOI
Influences from solvents on charge storage in titanium carbide MXenes
Xuehang Wang,Tyler S. Mathis,Ke Li,Zifeng Lin,Zifeng Lin,Lukas Vlcek,Lukas Vlcek,Takeshi Torita,Naresh C. Osti,Christine B. Hatter,Patrick Urbankowski,Asia Sarycheva,Madhusudan Tyagi,Madhusudan Tyagi,Eugene Mamontov,Patrice Simon,Patrice Simon,Yury Gogotsi +17 more
TL;DR: In this paper, the authors show how simply changing the solvent of an electrolyte system can drastically influence the pseudocapacitive charge storage of the two-dimensional titanium carbide, Ti3C2 (a representative member of the MXene family).
Journal ArticleDOI
A time-of-flight backscattering spectrometer at the Spallation Neutron Source, BASIS
TL;DR: BASIS is the first silicon-based backscattering spectrometer installed at a spallation neutron source and offers a high-energy resolution and a large and variable energy transfer range, which ensure an excellent overlap with the dynamic ranges accessible at other inelastic spectrometers at the SNS.
Journal ArticleDOI
Effect of Metal Ion Intercalation on the Structure of MXene and Water Dynamics on its Internal Surfaces.
Naresh C. Osti,Michael Naguib,Alireza Ostadhossein,Yu Xie,Paul R. C. Kent,Boris Dyatkin,Gernot Rother,William T. Heller,Adri C. T. van Duin,Yury Gogotsi,Eugene Mamontov +10 more
TL;DR: It is demonstrated that intercalation with potassium cations significantly improves structural homogeneity and water stability in MXenes, suggesting greater stability of hydrated MXene against changing environmental conditions.
Journal ArticleDOI
Multimodality of Structural, Electrical, and Gravimetric Responses of Intercalated MXenes to Water
Eric S. Muckley,Michael Naguib,Hsiu-Wen Wang,Lukas Vlcek,Naresh C. Osti,Robert L. Sacci,Xiahan Sang,Raymond R. Unocic,Yu Xie,Madhusudan Tyagi,Madhusudan Tyagi,Eugene Mamontov,Katharine Page,Paul R. C. Kent,Jagjit Nanda,Ilia N. Ivanov +15 more
TL;DR: It is found that MXene gravimetric response to water is 10 times faster than their electrical response, suggesting that H 2O-induced swelling/contraction of channels between MXene sheets results in trapping of H2O molecules that act as charge-depleting dopants.
