Synthesis of dehydrated zinc borates using the solid

Additionally at 600C two other types of dehydrated zinc borate compounds are obtained: Zn 3 (BO 3) 2 (ZB 2) (pdf no 01-071-2063) and ZnB 4 O 7 (ZB 3) (pdf no 00-016-0283) in which ZB 1 and ZB 3 exhibit different crystallographic properties even though they have the same structural formula

Structural properties of vegetables during air drying

The effect of moisture content on structural properties such as apparent density true density and porosity was investigated in this work for various vegetables after conventional drying Samples of twelve different fresh vegetables (mushroom green pepper courgete spinach celery leek onion tomato garlic carrot pea and corn) were dehydrated with conventional drying and the

Structural investigation of ribosomally synthesized

Ribosomally synthesized and posttranslationally modified peptides (RiPPs) constitute a promising repertoire of natural products with potentially useful properties Several tools have been developed in recent years to facilitate RiPP discovery and to connect genetic information with the chemical entities produced by microorganisms Structure elucidation remains challenging for the RiPP field
