Metilasi Asam Galat Menggunakan Agen Metilasi Dimetil Sulfat (DMS) atau Dimetil Karbonat (DMC) [PDF]

open access: yes, 2013
Methylation of gallic acid has been conducted by the use of dimethyl sulfate (DMS) or dimethyl carbonate (DMC) as methylating agents. Methylation of gallic acid using DMS was carried out by various methods, i.e.

Gallic Acid Derivatives From Mezoneuron Benthamianum Leaves

open access: yesPharmaceutical Biology (Formerly International Journal of Pharmacognosy), 2000
The leaves of Mezoneuron benthamianum yielded methyl gallate and gallic acid as the constituents responsible for its antibacterial activity. (-)-Shikimic acid-3-O-gallate, 1-O-methyl-D-chiro-inositol, (-)-epicatechin, (-)-epicatechin-3-gallate and kaempferol-3- (6?-galloyl) glucoside were also isolated.

GeAl2‐2xFe2xO3(OH)4 Nanotubes: New Electrocatalyst for Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
Fe‐doped imogolite nanotubes are synthesized via a one‐step hydrothermal method with varying Fe substitution ratios x. Structural and spectroscopic analyses confirm homogeneous Fe incorporation while preserving tubular shape. Optimal doping at x = 0.05 enhances optical absorption, narrows band gap, reduces charge transfer resistance, and significantly ...

Upconversion Nanoparticles Embedded Photonic Contact Lens for Transepithelial Corneal Crosslinking Using Hyaluronate – Riboflavin Conjugate

open access: yesAdvanced Functional Materials, EarlyView.
A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...

Electroactive Liquid Crystal Elastomers as Soft Actuators

open access: yesAdvanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Electrochemical characterization of gallic acid

open access: yes, 2021
Gallic acid (3, 4, 5 trihydroxybenzoic acid) is a polyphenol, known for strong anticancer, antioxidant, anti-inflammatory and antimutagenic properties. Additional advantage of selective cytotoxicity for cancerous cells, makes gallic acid important additive in food to prevent cancer risks.

Gallic acid alleviates ferroptosis by negatively regulating APOC3 and improves nerve function deficit caused by traumatic brain injury

open access: yesScientific Reports
Traumatic brain injury (TBI) is more common than ever and is becoming a global public health issue. A variety of secondary brain injuries occur after TBI, including ferroptosis characterized by iron-dependent lipid peroxidation.
