Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article introduces a novel, efficient method for synthesizing zinc oxide (ZnO) nanoparticles directly from an alkaline zinc solution using an acidic solution. This approach bypasses the need for calcination, making it a cost-effective and rapid alternative to existing methods. The study delves into the equilibrium analysis of the Zn²⁺–SO₄²⁻ aqueous system, revealing two distinct precipitation paths. The proposed method involves neutralizing sodium zincate with an acidic solution, leading to the direct formation of ZnO crystals. The synthesized nanoparticles exhibit high crystallinity and a specific surface area of approximately 20 m²/g, as determined by XRD and BET analysis. FESEM microscopy reveals spherical particles with a diameter of 30–50 nm, which form platelets by adhering laterally. This method holds promise for the rapid and low-cost production of ZnO, particularly from alkaline leaching solutions of zinc ores and wastes.
