Tetragallium(III) complex in [Ga4(L4-Py)2(dpm)6] ⋅ EtOH, with H3L4-Py=2-(hydroxymethyl)-2-(pyridin-4-yl)propane-1,3-diol and Hdpm=dipivaloylmethane, was investigated as a diamagnetic analogue of tetrametallic, propeller-like single-molecule magnets (SMMs). The chiral molecular structure partitions the six CH2 protons each tripodal (L4-Py)3− ligand into two diastereotopic sets. signals were clea...

BACKGROUND AND OBJECTIVES The authors produced a historical analysis of nine anesthesia-related premises described in the Bible more than 3,500 years ago (Old Testament). Anesthetic drugs and adjuvants, patients, anesthesiologists attitudes and techniques are discussed in the light of Biblical and modern science. CONTENTS To help understanding, the nine premises evaluated are correlated to th...

Reduction of phytate is a major goal of plant breeding programs to improve the nutritional quality of crops. Remarkably, except for the storage organs of crops such as barley, maize and soybean, we know little of the stereoisomeric composition of inositol phosphates in plant tissues. To investigate the metabolic origins of higher inositol phosphates in photosynthetic tissues, we have radiolabel...

Two isomeric molecules, 1,2-cyclohexanediol and isohexide (isosorbide isomannide) demonstrated potential as rigid building blocks in PLA plasticizer design with tunable material performances. Six candidates were synthesized via Fischer esterification bulk of the cores green platform chemicals levulinic acid valeric acid. The structures confirmed by 1H NMR ESI-MS. Based on calculated Hansen solu...

Abstract The relationship between extractant stereochemistry and their extraction performance has only poorly been established. In order to address a part of this concern, we investigated the Pu(IV) liquid‐liquid (LLE) by using N , ‐di‐(2‐ethylhexyl)butyramide (DEHBA), as well those its position isomers. DEHBA ( ββ ‐isomer) ‐(2‐ethylhexyl)‐ ‐(oct‐3‐yl)butyramide (EHOBA or αβ were synthesized mi...

The environmental carcinogen benzo(a)pyrene-7,8-diol-9,10-epoxide (BPDE) forms DNA adducts with unique stereochemistries that may have divergent biological fates, depending on how they are processed within a cell. To investigate the effect of DNA bulky adduct stereoisomerism on the mutagenic outcome of translesion DNA replication in a human cell extract, oligonucleotides were synthesized that c...

We report a molecular modeling study to investigate the polymer-carbon black (CB) composite-analyte interactions in resistive sensors. These sensors comprise the JPL electronic nose (ENose) sensing array developed for monitoring breathing air in human habitats. The polymer in the composite is modeled based on its stereoisomerism and sequence isomerism, while the CB is modeled as uncharged napht...
