Valorization of Garcinia humilis Residues in Active Collagen/Starch Films for Biodegradable Packaging Applications

Packaging Technology and Science, EarlyView.
Residues from Garcinia humilis were used to obtain a phenolic‐rich extract (GHRE) and incorporated into collagen–starch films. The addition of GHRE improved antioxidant activity, thermal stability and elasticity, while reducing water vapour permeability.

Canopy Position Influences CIELAB Coordinates of Peach Color [PDF]

HortScience, 1993
Differences in color development between exposed and shaded fruit during the growing season were determined for `Loring' and `Raritan Rose' peach (Prunus persica L. Batsch). The surface color of fruit exposed to sunlight in the upper canopy, and in the shade in the lower canopy, was measured with a tristimulus calorimeter, and L* a* b* values were ...

Segmentation and semantic labelling of RGBD data with convolutional neural networks and surface fitting [PDF]

, 2017
We present an approach for segmentation and semantic labelling of RGBD data exploiting together geometrical cues and deep learning techniques. An initial over-segmentation is performed using spectral clustering and a set of non-uniform rational B-spline ...

High Sensitivity Cardiac Troponin I Detection via MP‐Locked Aptamer and Multimeric DNAzyme‐Coupled Hyperbranched Hybridization Chain Reaction

Small, EarlyView.
We report a magnetic particle anchored locked aptamer platform integrated with hyperbranched HCR and DNAzyme amplification for enzyme‐free, ultrasensitive detection of cardiac troponin I. The assay achieves a 0.25 ng/L detection limit within 25 minutes and enables cross‐species MI detection, with machine learning classification reaching 90% accuracy ...

Tile Classification Using the CIELAB Color Model [PDF]

, 2005
An image processing algorithm was developed for tile shade classification on the basis of quantitative measurements in CIELAB color space. A total of 50 tile images of 10 types were recorded, and evaluated with the proposed algorithm in comparison with the conventional classification method. The objectivity of the method is based on the fact that it is

Record‐Low Compressibility in [N(C2H5)3CH3]FeCl4 Expands Phase Engineering Horizons in Hybrid Molecular Ferroelectrics

Small, EarlyView.
High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

Sustainable dyeing of silk with curled dock (Rumex crispus) extract for trace element removal, ultraviolet protection, antimicrobial and anti‐oxidant activity

Coloration Technology, EarlyView.
Abstract This study investigated the dyeability and functionality of silk dyed with curled dock leaf extract. The effects of sugar content and turbidity in the extracted dye solution on dyeing were analysed, along with K/S values and colour fastness, under varying temperatures and times.

Red era: Dyeing yak hair fibres red with in situ generated silver nanoparticles using silver nitrate and a flavonoid‐containing plant extract

Coloration Technology, EarlyView.
Abstract Plants and their extracts have been used for dyeing fabrics, skin and hair for thousands of years and have been experiencing a revival in the last years due to increasing health risks arising from oxidative hair dye precursors. We developed a novel two‐step method to dye keratin fibres based on in situ formed silver nanoparticles including a ...
