Validation of Boron Analytical Methods on Standard Reference Material Tomato Leaves from NIST No. 1573a with Isothermal Distillation by UV-Vis Spectrophotometry

Kovalen: Jurnal Riset Kimia, 2022
Boron analysis by UV-Vis spectrophotometry has been developed through distilling triethoxy borane into the curcumin solution. In the distillation of ester borane, an esterification reaction occurs between borate and ethanol.

COMPARATIVE CHARACTERISTICS OF AROMA PROFILE OF WILD AND CULTURED EDIBLE MUSHROOMS

Harčova Nauka ì Tehnologìâ, 2022
The increased consumption of edible mushrooms is not only due to their nutritional value, but also to their unique taste and specific flavor. The aroma of cultivated mushrooms is different from wild ones, it is often less pronounced. The aim of the study

Contribution to Casein Determination by UV Spectrophotometry

Acta Chemica Iasi, 2017
Abstract In the present paper, the interaction between copper ions and proteins is presented, in order to elaborate a simple and rapid spectrophotometric assay of casein in milk. Under alkaline conditions, copper ions form the biuret complex with the proteins, which can be used in protein determination. Although very specific, the biuret

with tetracycline: Combining UV‐visible spectrophotometry with principal component analysis

, 2021
UV-visible spectroscopy (UV-Vis) is routinely used in microbiology as a tool to check the optical density (OD) pertaining to the growth stages of microbial cultures at the single wavelength of 600 nm, better known as the OD600.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Affinity‐Tuned Albumin Hitchhiking Extends the Bioorthogonal Capture Window in Pretargeting Radiotheranostics

Advanced Healthcare Materials, EarlyView.
Pharmacokinetic engineering of clickable radioligands was achieved via albumin hitchhiking approach within a pretargeted radiotheranostics delivery platform. This approach reduced rapid renal elimination, expanded bioorthogonal capture window, boosted tumor uptake by ∼3.5‐fold, and improved the tumor‐to‐liver ratio by ∼6‐fold.

Transient Laser‐Shocked Synthesis of Amorphous Layer‐Supported Metal Nanocrystals for Efficient Nitrate Reduction

Advanced Materials, EarlyView.
A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...
