Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment
Advanced Functional Materials, EarlyView.Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Paraquat, diuron and atrazine for the renewal of chemical weed control in northern Cameroon [PDF]
, 1997 Au Nord-Cameroun, le paraquat est vulgarisé depuis 1987 et le diuron et l'atrazine depuis 1992, à la suite des recommandations de la SODECOTON et des tests réalisés par l'IRA en collaboration avec le CIRAD. Le paraquat montre une efficacité importante et

Advanced Functional Materials, EarlyView.The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

PECCI Code (Python Estimation for Carbon Concentration and Isotopes) for Calculating the Concentration and Stable Carbon Isotopic Composition of Dissolved Inorganic Carbon (DIC) in Precipitation for northwestern Arkansas [PDF]
, 2014 In karst settings, hydrograph separations using isotopic tracers are commonly and effectively used to quantify the proportions of rain rapidly delivered to springs along fractures and conduits during storm events.

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing
Advanced Functional Materials, EarlyView.Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D
