Assessment of the cytotoxic effect of carboxymethyl chitosan-loaded amygdalin nanoparticles against human normal and cancer cell lines

Discover Nano
In recent years, the development of antitumor drugs has been dedicated to natural products. Amygdalin is a natural herbal cyanoglycoside that has anticarcinogenic effect on many types of cancers once hydrogen cyanide (HCN) is released. The main objective

On dielectric membranes [PDF]

Journal of High Energy Physics, 2009
By placing a collection of membranes in 11 dimensional background supergravity six form field and considering the non-linear action of multiple membranes we obtain the potential for transverse scalar fields of membranes and study some possible vacuum configurations.

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

Advanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Architecture‐Driven Sensor Stability in Weft‐Knitted Engineering Textiles

Advanced Engineering Materials, EarlyView.
Textile‐integrated sensor architectures are systematically compared to evaluate their electromechanical behavior under combined mechanical and environmental loading. Pocket‐based integration exhibits stable and reproducible signals, whereas tunnel‐based routing shows higher sensitivity accompanied by increased variability.
