Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

STM carbon nanotube tips fabrication for critical dimension measurements

, 2005
Reconstruction errors due to the finite shape of the tip remain the major limitation of scanning probe microscopy for nanometer scale measurements. Carbon nanotubes are ideal SPM probes thanks to their nanometric diameter, high aspect-ratio and strength.

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

Advanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Exosome-mediated repair of spinal cord injury: a promising therapeutic strategy

Stem Cell Research & Therapy
Spinal cord injury (SCI) is a catastrophic injury to the central nervous system (CNS) that can lead to sensory and motor dysfunction, which seriously affects patients' quality of life and imposes a major economic burden on society.

A Novel Method for Quantifying The Sensitivity of a Non-Ideal Explosive

, 2017
High costs and safety risks are incurred when large-scale characterization tests on non-ideal explosives are performed, and may not be feasible with some explosives due to the lack of available material required to sustain a steady detonation.
