Honeywell Research Chemicals’ history in the industry dates back more than 200 years to when Chemist Johann Daniel Riedel started production of pharmaceuticals in Berlin. Today, Riedel-de Haën™, Fluka™, Hydranal™, Chromasolv™, TraceSELECT™ and many other world leading brands are now part of the Hone more
High-quality and low-moisture products with every application ✓ Double-layered inner septa with 3 large puncture areas ✓ Better handling thanks to the innovative closure design ✓ more
Fraunhofer ISE Demonstrates First Long-Term Methanol Synthesis from Blast Furnace Gas in a Miniplant
Methanol plays an important role for industry as a commodity chemical and is presently considered one of the key energy carriers in the rising hydrogen economy. However, conventional methanol production from coal and natural gas generates large amounts of greenhouse gas emissions. With the project C more
Report lays out future scenarios for global chemical industry
A new report sends a dire warning to the chemical industry, which it says is on track for a future global warming scenario with catastrophic consequences, and sets out tangible, credible pathways for the sector to become an enabler of a sustainable global economy by 2050, while overseeing dramatic g more
Direct conversion of carbon dioxide into bulk chemicals and liquid fuels
High-efficiency utilization of CO2 facilitates the reduction of CO2 concentration in the global atmosphere and hence the alleviation of the greenhouse effect. The chemical utilization of CO2, which refers to converting CO2 into value-added chemicals and liquid fuels, has a distinct and direct CO2 em more
Automated workflow for the determination of fatty acid methyl esters (FAME) in fat and fat containing food samples using a 90 sec. transesterification
The analysis of oils, fat and fat contain- ing food containing food via fatty acid methyl esters (FAME) is a common task in governmental, quality control (QC) or contract research laboratories (CRO). Most often the samples are processed manually, whi more
The second in the ‘Aroma Chemistry’ series, this graphic examines the smell of fresh-cut grass. This is oft-mentioned when discussions of favourite smells come up, so what are the chemical compounds behind it? Grass emits volatile organic compounds normally, even without being cut. Research has show more
Creating Capsules with Cubanes
A sextuply linked capsule incorporating two Ni(II) cubane units is formed when Ni(II) salts are reacted with N-aminoalkyl salicylamidato ligands in a 4:3 ratio in methanol. With a short (propyl) alkyl substituent, additional chloride counter ions are included in the cavity by occupation of one apex more
Versatile coordination of acetazolamide to ruthenium(II) p-cymene complexes and preliminary cytotoxicity studies
The carbonic anhydrase inhibitor acetazolamide (AcmH2) reacted with [(η6-p-cymene)RuCl(μ-Cl)]2 to afford [(η6-p-cymene)RuCl2(κN-AcmH2)], 1A, in near-quantitative yield. In methanol, 1A exists in equilibrium with 1B, being probably a coordination isomer, as established by VT 1H-EXSY NMR spectroscopy. more
Impact of “half-crown/two carbonyl” - Ca2+ Metal Ion Interactions of a Low Molecular Weight Gelator (LMWG) on its Fiber to Nanosphere Morphology Transformation with Gel-to-Sol ...
We report here a smart functional low molecular weight gelator (LMWG) L, containing unusual metal ion coordination site, i.e. “half-crown/two carbonyl”. The gelator L shows excellent gelation behavior with typical fibrillar morphology in acetonitrile, methanol and ethanol medium. Upon Ca2+ ion bindi more
