The relevance of point defects in studying silica-based materials from bulk to nanosystems [PDF]

, 2019
The macroscopic properties of silica can be modified by the presence of local microscopic modifications at the scale of the basic molecular units (point defects).

Enhanced photoluminescence emission from two-dimensional silicon photonic crystal nanocavities [PDF]

, 2009
We present a temperature dependent photoluminescence study of silicon optical nanocavities formed by introducing point defects into two-dimensional photonic crystals. In addition to the prominent TO phonon assisted transition from crystalline silicon at ~

Multi-scale gapped smoothing algorithm for robust baseline-free damage detection in optical infrared thermography [PDF]

, 2020
Flash thermography is a promising technique to perform rapid non-destructive testing of composite materials. However, it is well known that several difficulties are inherently paired with this approach, such as non-uniform heating, measurement noise and ...

Laser Scanning and the Continuous Wavelet Transform for Flatness Control [PDF]

, 2015
Current methods for surface flatness control in construction are based on sparse measurements and therefore may lead to inaccurate and imprecise results.

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Automatic detection of welding defects using the convolutional neural network [PDF]

, 2019
Quality control of welded joints is an important step before commissioning of various types of metal structures. The main obstacles to the commissioning of such facilities are the areas where the welded joint deviates from acceptable defective standards.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
