Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

Advanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

Advanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...

Rocking seismic excitations effect on inelastic response of reinforced concrete building with soft-story

Journal of Materials and Engineering Structures, 2021
Well-known problem with seismic design codes is that it does not take into account the rotational earthquake components. Only Eurocode 8, in Part 6, offers response spectra of rotational accelerations for the seismic design of slender and tall structures

Earthquake Rocking Response of Rigid Bodies [PDF]

Journal of the Structural Division, 1980
Using a computer program, the rocking and overturning response of rectangular blocks of various sizes and aspect ratios is studied under several strong motion earthquakes. The effect of coefficient of restitution and of vertically prestressing the blocks to the floor is also studied.

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

Advanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.
