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 tungstenbronze-type-like Single-phase polycrystalline ceramics Ba6−3xSm8+2xTi18O54 (x = 0.5) doping with Ca ions had been prepared through the conventional solid-state reaction process. The phases and structure of the ceramics were analyzed through X-ray diffraction and scanning electron microscopy. The microwave dielectric properties of the ceramics were studied using a network analyzer. In this paper, the quality factor (Q × f) by substituting Ca ions for Ba ions in (Ba1−αCaα) Sm2Ti4O12 solid solutions in A1-sites was reported. In addition, the relationship between crystal structure and microwave dielectric properties was discussed from the viewpoint of structural formula and occupational state of large cations such as Ba, Ca ions in A1-sites.
