Progress towards synthetic modelling of humic acid: Peering into the physicochemical polymerization mechanism

, 2011
Oxidative copolymerization of gallic acid (GA) and protocatechuic acid (PA) at 1:1 ratio provides a water soluble humic-acid-like polycondensate (HALP) which mimics fundamental physicochemical and spectroscopic properties of natural humic acid (HA).

ASSESSING ELECTRICAL AND PHYSICOCHEMICAL PERFORMANCE OF CHEMICALLY MODIFIED PALM OIL AS AN ALTERNATIVE TRANSFORMER LIQUID

, 2023
Numerous studies have been conducted on enhancing the dielectric properties of palm oil (PO) with the addition of nanoparticles (NPs). However, insufficient emphasis was given to its physicochemical properties, which are also critical for the function of

CHANGES IN C : N : Р RATIOS IN PLANT BIOMASS, SOIL AND SOIL MICROBIAL BIOMASS DUE TO THE WARMING AND DESSICATION EFFECT OF FLARING

Бюллетень Почвенного института им. В.В. Докучаева, 2018
Climate warming results in significant changes in the structure and functioning of terrestrial ecosystems. The ecosystems situated near oil-well gas flares may be used as model ones for studying warming effect on soil and vegetation.

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,
