Fischer-tropsch synthesis on iron-based catalysts: the effect of co-feeding small oxygenates [PDF]

, 1989
Co-feeding experiments have shown that ethers can participate substantially in the Fischer-Tropsch synthesis with iron catalysts. Dimethyl ether is thought to be capable of building up surface complexes which are very similar to those naturally occurring

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

Chemistry – A European Journal, EarlyView.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere

Preparation of organic hydrazides [PDF]

, 1959
Thesis (M.A.)--Boston UniversityDue to the actual high price of hydrazine, this chemical cannot be used in an economical preparation of organic hydrazides. A synthesis of such hydrazides can be envisaged by the reduction of N-nitroamides.

Simple Guanosine—Amino Acid Hybrids as Low Molecular Weight Hydrogelators

Chemistry – A European Journal, EarlyView.
Unexplored guanosine‐amino acid derivatives act as low molecular weight hydrogelators. Gelation is triggered by K+ ions and pH changes and relies on G‐quadruplex formation. Small changes in the amino acid structure have a strong impact on the mechanical properties of the gels.

Fluorinated Glycan Frameshifts: Automated Synthesis Expedites the Study of Glycan‐Protein Interactions by 19F‐BioNMR

Angewandte Chemie, Volume 138, Issue 12, 16 March 2026.
Given the prominence of 19F‐bioNMR in structural research, fluorinated glycans hold enormous potential in glycomimetic frameshift design. However, challenges associated with the stereocontrolled synthesis of these disruptive actors continue to frustrate advances. To address this, the automated synthesis of selectively C‐2 fluorinated glycans related to

Engineering Plant Biomass Lignin Content and Composition for Biofuels and Bioproducts

Energies, 2015
Lignin is an aromatic biopolymer involved in providing structural support to plant cell walls. Compared to the other cell wall polymers, i.e., cellulose and hemicelluloses, lignin has been considered a hindrance in cellulosic bioethanol production due to

Entropy‐Stabilized Pd/HEO Bifunctional Catalyst for Selective Aqueous‐Phase Hydrogenolysis of Cellulose to Ethylene Glycol

EcoEnergy, EarlyView.
An entropy‐stabilized Pd/HEO catalyst integrates Lewis acid and hydrogenation sites within a robust oxide–metal interface, enabling efficient and selective conversion of cellulose to ethylene glycol (68.3%) in water. ABSTRACT The selective conversion of cellulose into ethylene glycol (EG) under aqueous conditions is an attractive yet challenging route ...
