Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

Advanced Engineering Materials, EarlyView.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

Advanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

An Inkjet‐Printed Platinum‐Based Temperature Sensing Element on Polyimide Substrates

Advanced Engineering Materials, EarlyView.
An inkjet‐printed, meander‐structured, nanoparticle platinum‐based resistive temperature sensors on polyimide substrates are demonstrated as proof‐of‐concept. Optimized sintering at 250°C enables stable conductive structures. The Pt100‐ and Pt1000‐type sensors exhibit linear resistance–temperature characteristics with stable TCR in the 20°C–80°C range,

Tertiary lymphoid structures in cancer

Science, 2022
Tertiary lymphoid structures in cancer Tertiary lymphoid structures (TLSs) are lymphoid formations that are found in nonlymphoid tissues. TLS can develop in inflamed tissues and are associated with chronic inflammatory disorders, autoimmunity, and cancer. In the setting of tumors, TLSs facilitate the influx of immune cells into the tumor site

Tertiary Structure of Ribonuclease

Nature, 1967
A model is proposed of the polypeptide chain in bovine pancreatic ribonuclease based on a 2 A electron density map involving 7,294 reflexions and data from seven heavy atom derivatives. The molecule seems to be roughly kidney shaped with dimensions of about 38 × 28 × 22 A with a deep depression in the middle of one side.

Protein Tertiary Structure Prediction

Current Protocols in Protein Science, 2000
AbstractThis unit addresses how to predict the tertiary structure of a protein from its amino acid sequence using computational methods. Three types of prediction methods‐‐homology modeling, fold recognition, and ab initio prediction‐‐are introduced.

Protein Tertiary Structure Modeling

Current Protocols in Protein Science, 2001
AbstractInsights into the 3D‐structure of a protein have proven useful during experiment design. Experimentally elucidated structures are often not available, but comparative protein modeling provides a viable alternative in many cases. This unit presents comparative protein modeling and how to use the highly sophisticated but easy‐to‐use free software

Serpin tertiary structure transformation

Journal of Molecular Biology, 1991
Previous crystallographic analyses have demonstrated that proteolytic cleavage of the serpins can result in a dramatic transformation of their tertiary structure. Some 16 residues on the amino terminal side of the cleavage site are inserted into a large beta-sheet to become a central strand, separating the two cleaved residues by about 70 A.
