EXPLORING INTERNAL STANDARDS AND MATRIX MATCHING FOR LANTHANIDES DETERMINATION IN TEA BY LA-ICP-MS [PDF]

open access: yesQuímica Nova
Lanthanides (Lns) have been increasingly used in different fields, raising some concerns due to potential adverse effects to human life. In this work, it is proposed a laser ablation-inductively coupled plasma mass spectrometry (LA-ICP-MS) method for Lns

Whole-rock trace element analyses via LA-ICP-MS in glasses produced by sodium borate flux fusion

open access: yesBrazilian Journal of Geology, 2021
Trace elements provide crucial information about the origin and evolution of the Earth. One common issue regarding their analyses is the reduced analyte recovery during hot plate acid digestion for some geological samples. To overcome this, alkali fluxes

An Innovative Platform Merging Elemental Analysis and Ftir Imaging for Breast Tissue Analysis

open access: yesScientific Reports, 2019
Histopathology and immunohistology remain the gold standard for breast cancer diagnostic. Yet, these approaches do not usually provide a sufficiently detailed characterization of the pathology.

Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

open access: yesAdvanced Functional Materials, EarlyView.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Light‐Controlled Reversible Coassembly of Hybrid Functional Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
Light‐responsive hybrid nanostructures are formed by coassembling azobenzene‐ and PAH‐functionalized nanoparticles through reversible an tunable π interactions. The system enables tunable coupling between distinct components such as gold and magnetite or carbon nanotubes, producing switchable optical and magnetic properties under light and magnetic ...
