Distinguishing the Monomer to Cluster Phase Transition in Concentrated Lysozyme Solutions by Studying the Temperature Dependence of the Short-Time Dynamics

January 25, 2012

Author(s)

Peter Falus, Lionel Porcar, Emiliano Fratini, Wei-Ren Chen, Antonio Faraone, Kunlun Hong, Piero Baglioni, Yun Liu

Recently experiments that combine both small angle neutron scattering (SANS) and Neutron Spin Echo (NSE) have demonstrated that dynamic clusters can form in concentrated lysozyme solutions when a right combination of a short-ranged attraction and long

Dynamics of Hydration Water in Portland Cement with and without a Superplasticizer Studied by High-Resolution Quasi-Elastic Neutron Scattering

January 25, 2012

Author(s)

Hua Li, Emiliano Fratini, Francesca Ridi, Francesco Bausi, Piero Baglioni, Madhu Sudan Tyagi, Sow-Hsin Chen

The influence of a new comb-shaped polycarboxylate-based superplasticizer (CSSP) on the hydration kinetics and transport properties of aged cement pastes has been investigated by high-resolution Quasi-Elastic Neutron Scattering (QENS) and low temperature

EFFECT OF ETHANOL FUEL AND MICROBIOLOGICALLY INFLUENCED CORROSION ON THE FATIGUE CRACK GROWTH BEHAVIOR OF PIPELINE STEELS

January 25, 2012

Author(s)

Jeffrey W. Sowards, Timothy S. Weeks, Joseph D. McColskey, James R. Fekete, Jain Luke, Charles H. Williamson

Ethanol fuel production and consumption is expected to increase significantly in the near future. Existing pipeline infrastructure could be repurposed to transport ethanol and other biofuels from production sources, such as those located in the Midwest, to

Frequency Characterization of an External-Cavity Quantum Cascade Laser at 4.5 ym using a Frequency Comb

January 25, 2012

Author(s)

Kevin O. Knabe, Paul A. Williams, Fabrizio R. Giorgetta, Chris Armacost, Michael Radunsky, Nathan R. Newbury

We measure the frequency noise spectrum of a free-running external-cavity quantum cascade laser at 4.5 υm through sum frequency generation with a fiber frequency comb.

Quasi-Elastic Neutron Scattering Studies of the Slow Dynamics of Supercooled and Glassy Aspirin

January 25, 2012

Author(s)

Yang Zhang, Madhu Sudan Tyagi, Sow-Hsin Chen

Aspirin, also known as acetylsalicylic acid (ASA), is not only a wonderful drug, but also a good glass-former. Therefore,it serves as an important molecular system to study the near-arrest and arrested phenomena. In this paper, a high-resolution quasi
