Exploring Thermal and Mechanical Strains During Laying Down Process in Fused Filament Fabrication

Macromolecular Materials and Engineering, EarlyView.
This study analyzes strain evolution and thermal behavior during FFF of PLA using strain gauges and infrared imaging. Microstrain levels depend on printing conditions, with adhesion‐induced compression during cooling and peak strains in early layers. Microtomography shows minimal porosity, while thermal imaging reveals rapid heat penetration, strong ...

Enhancing Crystallinity of Electrospun Polylactic Acid Fibers: Insights into Formation Mechanisms and Property Modulation–A Review

Macromolecular Materials and Engineering, EarlyView.
Controlled processing, nucleating agents, and monitored post‐treatments improve electrospun PLA nanofiber crystallinity. Additionally, stereocomplexation of PLLA and PDLA further enhances this property. Together, these strategies enable scalable, sustainable fabrication of high‐performance PLA nanofibers, expanding their applicability across industrial,

A Peridynamic Framework for Modeling Progressive Failure in Porous Sandstone Indentation

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT A state‐based peridynamic model is proposed to simulate the failure mechanisms in porous rocks, using Bentheim sandstone as a specific example. Experimental observations reveal a transition from brittle to ductile failure under increasing triaxial compression. This behavior is attributed to pore compaction. The peridynamic model is enhanced to

Infrared Thermography in Pain Medicine

The Korean Journal of Pain, 2013
Since BC 400 when Hippocrates used temperature in a diagnosis by applying mud to a patient's body and speculating that dry areas had disease, temperature has been an important area of interest in medicine. The skin is a very important organ in temperature regulation, and body temperature is controlled by the combined control of the central and ...

Ru‐Ag Dual Atom Sites for Methane Detection Enabling Intelligent Thermal Runaway Warning in Lithium‐Ion Batteries

Rare Metals, EarlyView.
ABSTRACT Early detection of thermal runaway (TR) is essential for lithium‐ion battery (LIB) safety, as unchecked TR risks catastrophic failures in energy storage systems. Gas‐based sensing offers a faster and more direct approach by detecting decomposition products at the molecular level.

NIR‐Responsive Nano‐Integrated Magnesium Phosphate Cement Promotes Bone Regeneration via Osteoblast‐Exosome‐Osteoclast Crosstalk

Rare Metals, EarlyView.
ABSTRACT The limited osteogenic capacity of magnesium phosphate cement (MPC) has constrained its biomedical applications, underscoring the necessity to develop MPC with enhanced physical properties and bone‐forming capabilities. In this study, a multifunctional MPC system was developed by incorporating zoledronic acid‐loaded near‐infrared (NIR ...

Bifunctional Competitive Structure of Biomass Carbon‐Derived Metacomposites for Tunable ε′‐Near‐Zero and ε′‐Negative Responses

Rare Metals, EarlyView.
ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...
