Chaotic Direct Ink Writing (ChDIW) of Hybrid Hydrogels: Implication for Fabrication of Micro‐ordered Multifunctional Cryogels

Small Methods, EarlyView.
Multimaterial 3D printing is being used for the development of highly efficient and multifunctional materials capable of meeting both complicated technological needs and addressing the extreme environmental challenges posed by modern life. This study explores the combination of the microdesign dictated by chaotic flows with the macrodesign provided by ...

Probing Viscoelasticity of Polymeric Coatings Using Nonlinear Dynamic Atomic Force Microscopy

Small Methods, EarlyView.
For soft materials it is essential to characterize both the elastic and viscous material properties. Using an atomic force microscope, the hardening nonlinearity induced by a tip‐sample contact and bifurcation points can be used to separately estimate the visco‐ and elastic parts of the tip‐sample interaction force.

A systems‐theoretical exploration for understanding and enhancing policy design: Expanding an analytical locus with implications for policy studies

Systems Research and Behavioral Science, EarlyView.
Abstract Policy design has two analytical domains, policy design‐as‐formulation and policy design‐as‐content. The latter study policies as codified and constructed output of the formulation process, which is an activity directed to the process. The analytical concept ‘structural logic’ emerged as an internal property of policy text and has been ...

Physical structural assessment of a segmented concrete shell building floor prototype

Structural Concrete, EarlyView.
Abstract To reduce the significant environmental impact of the construction industry, building floors designed as concrete shells that work mainly in compression and that are segmented for prefabrication and disassembly offer a promising alternative to reinforced thick flat slabs.

Reactor Design for Chemical Reaction‐Diffusion Systems

ChemSystemsChem, EarlyView.
This review discusses methods for the design of reactors for studying reaction‐diffusion (RD) phenomena. Abstract The experimental study of reaction–diffusion‐driven chemical and biological systems is a key to understanding pattern formation in nature. Starting from experiments performed in a Petri dish or test tube, various reactors have been designed

Woodward and Hoffmann on Secondary Orbital Interactions. How to Make a Fine Two‐Course Meal from Leftovers**

The Chemical Record, EarlyView.
In February through April 1965, Hoffmann devised several MO tools to explain the regiochemistry of the Diels‐Alder and the preference of the Cope reaction to proceed by the chair rather than boat orientations, when both were possible. The secret lay in secondary orbital interactions that were revealed through qualitative perturbation theory.
