Lipids, pots and food processing at Hočevarica, Ljubljansko barje, Slovenia
The paper presents the results of lipid analyses of pottery samples from Ho≠evarica (Ljub- ljansko barje, Slovenia). Total lipid extracts were subjected to high temperature gas chromatography (HT-GC), gas chromatography-mass spectrometry (GC-MS) and ...

The replacement of the anodic OER in CO2RR with energy‐saving methanol oxidation reaction and the creation of a favorable microenvironment through interfacial Cl− ions enable concurrent formate production at industrial‐level current densities. Abstract The efficient electrocatalytic conversion of CO2 to formate is often impeded by the high energy ...

Chemical characterization of liquefaction products of an inertinite enriched northern Alaska coals [PDF]
A Northern Alaskan coal rich in inertinites was further enriched by density gradient separations. The degree of condensation of the enriched coal was estimated to be low, mainly 3 ring.

Hydrogen Evolution on Hydrophobic Aligned Carbon Nanotube Arrays [PDF]
We investigate for the first time hydrophobic carbon nanotube-based electrochemical cells as an alternative solution to hydrogen sorting. We show that the electrically conducting surface of the nanotube arrays can be used as a cathode for hydrogen ...

Analysis of α-lipoprotein cholesterol in 50 μl of plasma
A micromethod for quantitation of α-lipoprotein cholesterol was devised for gas–liquid chromatography to minimize plasma sample size and facilitate lipid studies using capillary blood from children or small animals. α-Lipoprotein cholesterol was measured

Detection and quantification of phytosterols in yogurt using gas chromatography [PDF]
Sterols form the largest proportion of the unsaponifiable fraction of lipids. Plant fats and oils contain phytosterol as naturally occurring constituents.
