ELECTRON-INDUCED (EI) MASS FRAGMENTATION IS DIRECTED BY INTRA- MOLECULAR H-BONDING IN TWO ISOMERIC BENZODIPYRAN SYSTEMS

Electron-Induced (EI) Mass Fragmentation is Directed by Intra- molecular H-Bonding in Two Isomeric Benzodipyran Systems

The striking differences observed in the electron-induced (EI) mass fragmentationpathways of two isomeric benzodipyrans are attributable to hydrogen bonding in thesemolecules.In the "angular" isomer, 6-butyryl-5-hydroxy-2,2,8,8-tetramethyl-3,4,9,10-tetra-hydro-2H,8H-benzo[1,2-b:3,4-b1]dipyran (2), H-bonding occurs between the Ear Cleaner aromatic O

Application of a Quality-Specific Environmental Risk Index for the Location of Hives in Areas with Different Pollution Impacts

Honeybees and hive products have long been recognized as excellent bio-indicators, as they provide valuable information on the state of the environments concerned.As yet, however, no tool is capable of contextually assessing the level of pollution of different environmental matrices in order to create maps of areas in which to place hives.In this p

A Hybrid Method for Three-Level T-Type Inverters to Eliminate Neutral Point Voltage Ripple and Control DC-Link Capacitors’ Voltage for Separate MPPT

Nowadays, photovoltaic (PV) systems based on centralized topology with a three-level T-type (3LT2) inverter are used to decrease investment costs and increase conversion efficiency.In this topology, the split capacitors of the DC-link can individually connected to PV arrays.Accordingly, DC-link capacitors’ voltage should separately controlle
