Investigation of Mechanical and Thermal Properties of Modified Silica Aerogels/Epoxy/Aramid Composites

Polymer Composites, EarlyView.
Production process of amine‐modified silica aerogel reinforced aramid/epoxy composite (EAFS). ABSTRACT Due to its high pore size and low density, amine‐modified silica aerogel (XSA) is an excellent candidate for the secondary reinforcement material of polymer matrix composites.

Effect of Different Laundering and Drying Procedures on the Performance of Fire‐Protective Fabrics

Journal of Polymer Science, EarlyView.
ABSTRACT Fire‐protective fabrics play a critical role in keeping firefighters and other workers exposed to heat and flame hazards safe. However, some fibers used in these fabrics are sensitive to laundering, which may lead to significant reductions in their performance.

Integrated Modeling of Digital‐Motor and Clinician‐Reported Outcomes Using Item Response Theory: Towards Powerful Trials for Rare Neurological Diseases

CPT: Pharmacometrics &Systems Pharmacology, EarlyView.
ABSTRACT Robust and highly sensitive outcomes are crucial for small trials in rare diseases. Combining different outcome types might improve sensitivity to identify disease severity and progression, yet innovative methodologies are scarce. Here we develop an Item Response Theory framework that allows integrated modeling of both continuous and ...

Anticlastic Curvature and Material Freedom

physica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

An Extended Hückel Theory Parameter Set for Efficient Electronic Structure Calculations of SiGe Alloys

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
A new parameterization of Si and Ge in the framework of the extended Hückel theory is presented. Bandgap and effective mass are calculated for unstrained and biaxially strained SiGe alloys. In SiGeC alloys with C atoms in close proximity, additional bands are observed, which are related to defect states in real crystals.
