An amino acid based system for CO2 capture and catalytic utilization to produce formates [PDF]

open access: yes, 2021
Herein, we report a novel amino acid based reaction system for CO2 capture and utilization (CCU) to produce formates in the presence of the naturally occurring amino acid l-lysine.

Sensitive and Facile HCOOH Fluorescence Sensor Based on Highly Active Ir Complexes’ Catalytic Transfer Hydrogen Reaction

open access: yesMolecules, 2022
With several major polarity and weak optical properties, the sensitive detection of HCOOH remains a major challenge. Given the special role of HCOOH in assisting in the catalytic hydrogenation process of Ir complexes, HCOOH (as a hydrogen source) could ...

Palladium(II)-Catalyzed Regioselective Hydroesterification of 1,3-Conjugated Enynes with Aryl Formates

open access: yes, 2023
An effective Pd-catalyzed regioselective hydroesterification of 1,3-conjugated enynes with aryl formates was developed. Under the Pd–CyDPEphos catalytic system, the conjugated enynes reacted with phenyl formates and selectively provided the 2-ester ...

Stereoselective Syntheses of Protected Amino-hydroxy-cyclopentane-carbaldehyde Derivatives from 7-Oxabicyclo[2.2.1]hept-5-en-2-yl Systems

open access: yesCHIMIA, 1990
Cycloaddition of azido formates to the double bond of 7-oxabicyclo[2.2.1]hept-5-en-2-yl derivatives gave mixtures of triazolines that could be separated by chromatography.

Magneto-elastic coupling in multiferroic metal-organic framework [(CH3)2NH2]Co(HCOO)3

open access: yesAIP Advances, 2021
Metal-organic frameworks based on metal-formates have emerged as a intriguing class of multiferroics with wide range of applications. In this work, we present magneto-Raman spectroscopic investigations on [(CH3)2NH2]Co(HCOO)3 belonging to this family ...

‘Copper and Bronze in Art’ and the Search for Rare Corrosion Products

open access: yesHeritage, 2023
The information taken from David A. Scott’s book “Copper and Bronze in Art” was crucial for this research on copper corrosion products in Stuttgart. The examples discussed are: (1) the nature and variability of ‘Black Spots’ (or ‘Brown Fuzzies’), mainly ...

The infrared spectra of several rare-earth formates [PDF]

open access: yes, 1975
The IR spectra in the range of 4000-100 cm-1 of the following rare-earth formates were studied: Ce(HCOO)3, Pr(HCOO)3, Nd(HCOO)3, Nd(HCOO)3, Sm(HCOO)3, Eu(HCOO)3 and Gd(HCOO)3.

Solvent-derived defects suppress adsorption in MOF-74

open access: yesNature Communications, 2023
Defects in metal-organic frameworks (MOFs) have great impact on their nano-scale structure and physiochemical properties. However, isolated defects are easily concealed when the frameworks are interrogated by typical characterization methods.
