Thin Layer Chromatography of Marihuana

Journal of AOAC INTERNATIONAL, 1972
The various TLC methods employed in the separation and identification of Cannabis products to date are reviewed. Two solvent systems are recommended for rapid identification of marihuana: multiple development, semiquantitatiom, and wedge and loose-layer chromatographic techniques are discussed.

Origin of Dark Current Robustness in Photomultiplication Organic Photodetectors Enabled by Ionic Conjugated Electron‐Blocking Layers

Advanced Materials, EarlyView.
Ionic conjugated polyelectrolyte electron‐blocking layers enable photomultiplication organic photodetectors with dark current robustness up to −10 V and external quantum efficiencies exceeding 3000%. Fowler–Nordheim tunneling, interfacial dipole, trap density of states, and noise analyses reveal how ionic conjugated polyelectrolytes suppress electron ...

Thin-layer chromatography: An efficient method for the optimization of dispersive liquid-liquid microextraction

Acta Chimica Slovenica, 2018
Thin-layer chromatography (TLC) is an often omitted analytical technique due to its lower sensitivity and separation capacity. Even in the era of high-performance liquid chromatography (HPLC), thin-layer chromatography still offers many advantages, such ...

A High‐Resolution THz‐PCF Sensing Framework: Precise Identification of Food Preservatives Through Refractive Index Analysis

Advanced Materials Interfaces, EarlyView.
As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...

Turning Humidity Into Function: Heterojunction Interfaces for Dual‐Mode Removal of Nonpolar Vapors

Advanced Materials Interfaces, EarlyView.
A wire‐grown MIL–88B(Fe)@Fe3(PO4)2 heterojunction converts ambient humidity into a functional mediator for nonpolar VOC purification. Water forms a hydration layer that enhances cyclohexane uptake while simultaneously promoting •OH generation, resulting in synergistic adsorption–photocatalysis under humid conditions.

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

Advanced Materials Interfaces, EarlyView.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

Reconnaissance Peptide Labeling Grain Boundary of Chemically Grown MoS2 Polycrystalline Monolayer

Advanced Materials Technologies, EarlyView.
Self‐assembled peptides on substrates, through adsorption and aggregation, offer an alternative way to label grain boundaries in chemically grown single‐layer polycrystalline MoS2. During an early nucleation step, peptides preferentially bind to grain boundaries.
