RIBFIND: a web server for identifying rigid bodies in protein structures and to aid flexible fitting into cryo EM maps

open access: yes, 2012
Motivation: To better analyze low-resolution cryo electron microscopy maps of macromolecular assemblies, component atomic structures frequently have to be flexibly fitted into them.

Numerical and experimental study of semi-rigid beam-to-column composite connections in cold-formed steel

open access: yes, 2020
The concept of cold-formed steel has been expanded recently from semi-rigid bolted moment connection to the composite construction. Partial strength beam-to-column composite connection is performed by anchoring reinforcement bars to the column member and

Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays

open access: yesAdvanced Materials, EarlyView.
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...

An Approach for Modelling Accidental Eccentricity Effects in Symmetrical Frame Buildings Exhibiting Semi-Rigid Diaphragm Behavior

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi
The accidental eccentricity effect is specified, in earthquake codes, to account for the possible uncertainties in the mass and stiffness distribution of the structural system and the effect of the torsional component of the earthquake ground motion on ...

Perbandingan penerapan rigid dan semi rigid diaphragm pada bangunan bertingkat

open access: yes, 2017
Diaphragm design is important to be studied and calculated, because the diaphragm serves to tie each vertical elements together to resist the forces. Generally, engineers tend to assume that diaphragm of building structure is rigid, but the architect ...

Strengthened Interfacial Coupling Between Self‐Assembled Monolayers and Bulk Heterojunctions Enables Thermally Stable Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Molecularly engineered self‐assembled monolayers (SAMs) featuring extended conjugated terminals facilitate superior interfacial coupling with the organic solar cell active layer. By physically anchoring the local morphology, this design suppresses thermal degradation, allowing devices to operate at 85°C for 150 h before degrading to 90% of their ...

E. coli Extracellular Matrix: A Tunable Composite With Hierarchical Structure

open access: yesAdvanced Materials, EarlyView.
The complex composite‐like mechanical behavior of E. coli biofilm matrix is the result of a synergic contribution of the rigid curli and swelling pEtN‐cellulose, and emerges from specific ratio and assembly conditions. The interactions between the two fibers govern biofilm hydration and characteristic wrinkling patterns, providing crucial insights for ...
