Morphological plasticity of astroglia: Understanding synaptic microenvironment

, 2015
Memory formation in the brain is thought to rely on the remodeling of synaptic connections which eventually results in neural network rewiring. This remodeling is likely to involve ultrathin astroglial protrusions which often occur in the immediate ...

Micromechanical analysis of kinematic hardening in natural clay

, 2009
This paper presents a micromechanical analysis of the macroscopic behaviour of natural clay. A microstructural stress-strain model for clayey material has been developed which considers clay as a collection of clusters.

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Applying biologically anchored subtypes to advance precision medicine in autism spectrum disorder

Neurobiology of Disease
Autism spectrum disorder (ASD) is heterogeneous at every level, from behavior to molecular pathways, limiting the value of subgrouping schemes built on surface phenotypes alone.

Ductile fracture simulations using a multi-surface coupled damage-plasticity model

, 2017
In this paper, an isotropic porous metal plasticity model accounting for both void growth by diffuse plastic deformation and void ‘coalescence’ by localization of plastic flow in the inter-void ligaments is presented. Predictions for the effective stress-strain response, evolution of damage and the strains to failure are obtained by integrating the model ...

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Low molar mass ionic liquid’s modified carbon nanotubes and its role in PVDF crystalline stress generation

Nanotechnology Reviews
In this work, the question is whether the positive charge or the confirmation of side chain of an ionic liquid l-methylimidazolium bromide or the modified solid support multi-walled carbon nanotubes affects the heterogeneous crystallization of melt ...

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

Advanced Materials, EarlyView.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

An integrated multiscale simulation guiding the processing optimisation for additively manufactured nickel-based superalloys

Virtual and Physical Prototyping
Microstructural defects in laser powder bed fusion (LPBF) metallic materials are correlated with processing parameters. A multi-physics model and a crystal plasticity framework are employed to predict microstructure growth in molten pools and assess the ...
