Predicting Collagen Triple Helix Stability through Additive Effects of Terminal Residues and Caps
Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023 Collagen model peptides are like a construction set. The stability of collagen triple helices is critically determined by the frame, terminal residues, capping groups, and their charge state. The effects are additive and can be used to predict the melting temperatures of new collagen trimers.

Advanced Functional Materials, EarlyView.Copper sulfide based electrocatalysts for CO2 conversion are selective for production of formate as major product. Transformations under electrochemical conditions result in significant sulfur loss, and this study examines the nature of how persistent, residual sulfur (observed as surface SO42– species and S dissolved in the electrolyte) can sustain ...

UNCERTAINTY MANAGEMENT IN SEISMIC VULNERABILITY ASSESSMENT USING GRANULAR COMPUTING BASED ON COVERING OF UNIVERSE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 Earthquake is an abrupt displacement of the earth's crust caused by the discharge of strain collected along faults or by volcanic eruptions. Earthquake as a recurring natural cataclysm has always been a matter of concern in Tehran, capital of Iran, as a ...

Multiresolution analysis for efficient, high precision all-electron density-functional calculations [PDF]
, 2001 Multiresolution analysis of electronic structure affords the opportunity to capture the full physics of atomic cores in a systematically improvable manner. Applying new techniques, we demonstrate for the first time that multiresolution analysis of all-electron calculations within density-functional theory can be carried out to high precision with a ...

A Flexible Photovoltaic Fatigue Factor for Quantification of Mechanical Device Performance
Advanced Functional Materials, EarlyView.The flexible Photovoltaic fatigue factor (F) quantifies mechanical and photovoltaic performance as a function of the power conversion efficiency (PCE), the strain (ε${\varepsilon}$), and the number of bending cycles (NBC) in bending tests. The strain depends on the bending radius (R) and the thicknesses of the substrate (ts) and the photovoltaic device

High mobility two-dimensional electron system on hydrogen-passivated silicon(111) surfaces [PDF]
, 2005 We have fabricated and characterized a field-effect transistor in which an electric field is applied through an encapsulated vacuum cavity and induces a two-dimensional electron system on a hydrogen-passivated Si(111) surface. This vacuum cavity preserves the ambient sensitive surface and is created via room temperature contact bonding of two Si ...
