Spectroscopy and RGB-Colorimetry for Quantification of Plant Pigment and Fruit Content in Fruit Drinks

open access: yes, 2018
Collimated Transmission Spectroscopy (CTS) is a technique that is commonly used to study the optical absorption of different media. In this work CTS was used to measure the absorbance of pure raspberry juice in order to investigate how well the fruit ...

Controlled Lattice Distortion and Lattice‐Strain‐Engineered CoCuIr Alloy toward Preferential Chlorine Tolerant Direct Seawater Electrolysis

open access: yesAdvanced Science, EarlyView.
A lattice‐strain‐engineered Co0.28Cu0.67Ir0.05 trimetallic alloy nanoparticle electrocatalyst is rationally designed for efficient alkaline seawater electrolysis. Larger Ir atoms in the CoCu lattice modulate the local coordination environment, generating compressive lattice strain and highly active catalytic sites.

Colorimetry laboratory at NBS

open access: yes
This image is part of the Colorimetry collection. Colorimetry is the science behind the measurement of color. A variety of industries and interest groups pushed the National Bureau of Standards (NBS) to standardize color at the beginning of the 20th ...

Imaging colorimetry using a digital camera

open access: yes, 2000
In this work, we investigate the use of a digital camera for colorimetry. Our system consists of a measurement device and a corresponding calibration mapping. The goal is to design a system that will accurately assess the color of a sample.

A Metal‐Polyphenol Self‐Assembled Coated 3D Sponge With Mild Photothermal Antibacterial, Exudate‐Controlling, and Immunomodulatory Functions for Hemostasis and Chronic Wound Healing

open access: yesAdvanced Science, EarlyView.
A thrombin‐functionalized copper‐polydopamine nanofiber sponge integrates rapid hemostasis, mild photothermal antibacterial therapy, stimulus‐responsive Cu2+ release, chemodynamic oxidative stress, and macrophage immunomodulation. This multifunctional dressing suppresses infection, regulates inflammation, promotes angiogenesis and re‐epithelialization,

Interleukin‐1α Mediates Pancreatic Fibroblast Activation, Regulates Immune Cell Recruitment and Fibrosis in Acute and Chronic Pancreatitis

open access: yesAdvanced Science, EarlyView.
During pancreatitis, IL‐1α is released from necrotic acinar cells. In response to IL‐1α, pancreatic fibroblasts release chemokines and cytokines that regulate the recruitment of immune cells to the damaged organ. Furthermore, IL‐1α primes fibroblasts, resulting in increased tissue fibrosis during chronic pancreatitis.

Functional–Taxonomic Scaling Resolves Conflicting Average Genome Size Estimates Across Environmental Gradients

open access: yesAdvanced Science, EarlyView.
Based on genome size‐functional breadth theory, we introduce and validate a framework that adjudicates conflicting average genome size (AGS) estimates by testing which estimate yields a gap between scaled functional diversity and scaled taxonomic diversity that is consistent with the expected positive association between genome size and gene functional

Mechanophore‐Based Multichannel Colorimetric Force Sensors: Ultrasound‐Driven Stress and Strain Quantification

open access: yesAdvanced Science, EarlyView.
ABSTRACT Mechanophores with mechanochromic properties have attracted significant attention as force‐responsive materials for structural sensing. However, their applications remain mainly limited to qualitative force visualization, as direct and quantitative extraction of mechanical parameters such as stress and strain from mechanochromic responses has ...
