Experimental and numerical study of AA5086-H111 aluminum plates subjected to impact [PDF]
An experimental and numerical study of medium-velocity impact (within the range of 120 m/s) has been conducted on thin AA5086-H111 aluminum square plates. Targets with different thicknesses (between 2.5 and 4 mm), stratifications and aluminum alloys have

Flexographic Printed Flexible Thermochromic Stickers for Smart Sensing Applications
Thermochromic complexes of 1‐butyl‐3‐methylimidazolium chloride and 4‐chloronickelate are synthesized and incorporated in hydroxypropyl cellulose‐based water inks. Films with 40 wt.% thermochromic complexes and three layers are flexographic printed on polypropylene tags in a process compatible with roll‐to‐roll manufacturing. After encapsulation with a

This study explores the development of sol–gel coatings for archaeological glass conservation. By formulating silica‐based solutions with low acid concentrations and applying them via dip coating, protective films are prepared at room temperature. Analysis reveals that hybrid coatings with methyl and octyl groups provide superior protection against ...

Zinc Chalcogenide Based Shell Layers for Colloidal Quantum Wells
A new synthetic route is developed for the synthesis of CdSe/ZnSe/ZnS multi‐shell nanoplatelets (NPLs) with emissions between 615 and 630 nm and photoluminescence quantum yields up to 90%. Control over the lateral size of the starting CdSe core enabled the narrowing of the emission linewidth to 20 nm.

In order to better understand the complex crystallization dynamics of starch‐assisted metal halide perovskites (MHPs), the properties of colloidal precursor suspensions and the thermodynamic evolution of the crystallization reaction are investigated by a comprehensive set of characterization techniques, from solutions to films.

This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...
