Self-assembly of copolyesters into stereocomplex crystallites tunes the properties of polyester nanoparticles

Self-assembly of polyesters like PlLA and PdLA into stereocomplexes (SCs) is an interesting approach to tailor physical properties of polymeric nanoparticles without affecting their hydrophilicity. Here,...

1,7,9,10-tetrasubstituted PMIs accessible via decarboxylative bromination: Synthesis, Characterization, Photophysical Studies and Hydrogen Evolution Catalysis

In this work, we present a new synthetic strategy for fourfold substituted perylene monoimides via tetrabrominated perylene monoanhydrides. X-Ray diffraction analysis unveiled intramolecular stacking orientation...

Plasma-based VAD process for multiply doped glass powders and high-performance fiber preforms with outstanding homogeneity

An innovative approach using the vapor axial deposition (VAD), for the preparation of silica‐based high‐power fiber laser preforms, is described in this study. The VAD uses a plasma deposition system...

Synchronous single-photon detection with self-resetting, GHz-gated superconducting NbN nanowires

We demonstrate a GHz-gated operation of resonator-coupled superconducting nanowire single-photon detectors suitable for synchronous applications. In comparison with conventional dc-biased nanowire detectors,...

Surface damage resistance and yielding of chemically strengthened silicate glasses: From normal indentation to scratch loading

We report on surface elasticity, plastic deformation and crack initiation of chemically strengthened soda- lime silicate and sodium aluminosilicate glasses during lateral indentation and scratch testing....

FN 3-5 | Automatic segmentation and classification of fungal infected tissue using Deep learning

When the human immune system is weakened, fungal infections can lead to a life-threatening condition in humans. In order to determine the type of fungus, pathologists perform tissue biopsies for further...

Multi-wavelength, handheld laser speckle imaging for skin evaluation

Objective: A handheld device was developed and qualified for in vivo human skin evaluation using laser speckle imaging technology. Methods: Each laser speckle device prototype allows the choice of up to...

Scalable Functionalization of Optical Fibers Using Atomically Thin Semiconductors

Atomically thin transition metal dichalcogenides are highly promising for integrated optoelectronic and photonic systems due to their exciton-driven linear and nonlinear interactions with light. Integrating...

Material-specific imaging of nanolayers using extreme ultraviolet coherence tomography

Staphylococcus aureus and Methicillin Resistant S. aureus in Nepalese Primates: Resistance to Antimicrobials, Virulence and Genetic Lineages

Staphylococcus aureus is a ubiquitous pathogen and colonizer in humans and animals. There are few studies on the molecular epidemiology of S. aureus in wild monkeys and apes. S. aureus carriage in rhesus...
