Freeform Manufacturing of Plant‐Based Structural Colors for Scalable Photonic and Mechanochromic Devices

Advanced Materials, Volume 38, Issue 35, 23 June 2026.
A green, freeform manufacturing approach that utilizes robust aqueous two‐phase systems to create intricate and scalable photonic structures and non‐planar mechanochromic hydrogel actuators from plant‐based hydroxypropyl cellulose. This approach broadens the structural possibilities of sustainable photonic devices and mechanochromic systems, offering ...

Turing Instabilities are Not Enough to Ensure Pattern Formation

Bulletin of Mathematical Biology
AbstractSymmetry-breaking instabilities play an important role in understanding the mechanisms underlying the diversity of patterns observed in nature, such as in Turing’s reaction–diffusion theory, which connects cellular signalling and transport with the development of growth and form.

Turing instability in reaction–diffusion models on complex networks [PDF]

Physica A: Statistical Mechanics and its Applications, 2016
In this paper, the Turing instability in reaction-diffusion models defined on complex networks is studied. Here, we focus on three types of models which generate complex networks, i.e. the Erdős-Rényi, the Watts-Strogatz, and the threshold network models. From analysis of the Laplacian matrices of graphs generated by these models, we numerically reveal

Silicon allotropes by large‐volume high‐pressure techniques: crystal growth mechanisms, phase diagrams and hexagonal nanostructured Si‐6H by in situ X‐ray diffraction and computational methods

Acta Crystallographica Section B, Volume 82, Issue 3, Page 280-298, June 2026.
In situ X‐ray diffraction is used for exploring Si crystallography and for studying phase‐transformation mechanisms in elemental Si and Na–Si systems. We present original results of hexagonal silicon, Si‐6H and a critical analysis of the past‐decade discoveries of silicon Si‐4H and Si24 using large‐volume high‐pressure techniques.Metastable allotropes ...

AI Revolution and Warfare: A New Paradigm Shift in Defence Procurement, Restructuring, Training, and Recruitment

Canadian Public Administration, Volume 69, Issue 2, Page 250-277, June 2026.
Abstract The war in Ukraine and Israel's successful operations have demonstrated the apparent shift in military operations, strategic defence spending, and innovations. Drawing parallels to the industrial revolution and how it slowly transferred military procurement, training, and deployment, the current study also highlights the AI revolution and the ...

The Role of Inducible Defence in Ecological Models: Effects of Nonlocal Intraspecific Competition

Studies in Applied Mathematics, Volume 156, Issue 6, June 2026.
ABSTRACT Phenotypic plasticity significantly influences species interactions, especially via inducible defensive mechanisms in predator–prey dynamics. This work proposes and explores a predator–prey scenario whereby the prey species demonstrates inducible defence mechanisms against predators.
