Design study of the geometry of a punching/blanking tool [PDF]

, 1992
The cost of tooling in sheet metal industries contributes a considerable part to the overall cost of manufacturing a component. It is therefore imperative to keep down this cost by ensuring that the tool works for a long period in production without ...

Manufacture of 3D Compact Graphene Oxide Macrostructures

Advanced Materials Interfaces, EarlyView.
This article discusses methods to manufacture 3D graphene oxide‐based compact macrostructures, including molding, origami and kirigami, stimuli‐responsive deformation, and 3D printing. The compact morphology makes the graphene oxide‐based structures achieve high mechanical stiffness and strength to satisfy applications that need excellent mechanical ...

Tailor‐Made Vinylogous Urethane Vitrimers Based on Binary and Ternary Block and Random Copolymers: An Approach toward Reprocessable Materials

Macromolecular Chemistry and Physics, Volume 224, Issue 1, January 2023., 2023
Microphase separated block copolymers obtained by photoiniferter reversible addition‐fragmentation chain transfer polymerization are used for the formation of vinylogous urethane vitrimers. Depending on the composition of the block copolymers, crosslink density, and the diamine crosslinkers for the thermoreversible exchange reactions, reprocessable ...

Punching shear in concrete reinforced flat slabs with steel fibers and shear reinforcement

Revista IBRACON de Estruturas e Materiais, 2018
Steel fibers in reinforced concrete increase the performance of slab-column connection once they increase ductility and energy absorption capacity of the concrete. The use of fibers in flat slabs may increase strength and change the mode of failure.

Fast Privacy-Preserving Punch Cards [PDF]

arXiv, 2020
Loyalty programs in the form of punch cards that can be redeemed for benefits have long been a ubiquitous element of the consumer landscape. However, their increasingly popular digital equivalents, while providing more convenience and better bookkeeping, pose a considerable privacy risk.

A Systematic Study of Staphylococcus aureus Biofilm Formation on Thiol‐Ene Polymers: Toward the Development of Microfluidic Bacterial Biofilm Models

Advanced Materials Interfaces, EarlyView.
This work presents a systematic characterization of an emerging polymer platform, off‐stoichiometry thiol‐ene, in terms of its ability to support the formation, growth, and metabolic activity of Staphylococcus aureus biofilms. The findings indicate that thiol‐enes promote S.

Modification of CNF‐Networks by the Addition of Small Amounts of Well‐Defined Rigid Cationic Nanolatexes

Macromolecular Chemistry and Physics, Volume 224, Issue 1, January 2023., 2023
Cellulose nanofibril networks are modified by well‐defined cationic nanolatexes synthesized through reversible addition–fragmentation chain‐transfer‐mediated polymerization‐induced self‐assembly. Minute additions of nanolatexes impact the macroscopic mechanical properties, and the observed effects depend on the integrity of the nanolatexes' core–shell ...

Quantifying structure-property relationships during resistance spot welding of an aluminum 6061-T6 joint [PDF]

arXiv, 2016
Microstructure-property relationships of resistance spot welded 6061-T6 aluminum alloy lap joints were investigated via mechanical testing and microscopy techniques. Quasi-static tensile and novel shear punch tests were employed to measure the mechanical properties of the distinct weld regions.

Epithelial Cell Mechanoresponse to Matrix Viscoelasticity and Confinement Within Micropatterned Viscoelastic Hydrogels

Advanced Science, EarlyView.
Extracellular matrix (ECM) viscoelasticity and spatial confinement regulate cellular processes such as cancer progression, yet their interplay remains poorly understood. By developing fibronectin (FN)‐micropatterned viscoelastic hydrogels mimicking breast cancer mechanics, this study explores breast epithelial cell mechanoresponse to ECM ...

Combining Cryogel Architecture and Macromolecular Crowding‐Enhanced Extracellular Matrix Cues to Mimic the Bone Marrow Niche

Macromolecular Chemistry and Physics, Volume 224, Issue 1, January 2023., 2023
The development of a bone marrow niche model that closely mimics the natural 3D architecture of trabecular bone and the extracellular stromal compartment is reported. Macroporous cryogel scaffolds are functionalized with tissue‐specific, cell‐secreted ECM biopolymers. Macromolecular crowders enhance both ECM production and altered the microstructure of
