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

A comparison study has been made on thermal degradation of poly(L-lactide) (PLLA) to investigate the influences of two different zeolites filled through thermogravimetric analysis. Non-isothermal degradation measurements are conducted at a N2 flow rate of 30 ml/min along with a constant heating rate of 5–30 K/min. The thermal degradation features of PLLA/zeolite composites are compared in terms of some specific degradation temperatures. With the selected kinetic method, the activation energy E a values of two different zeolite-filled composites have been calculated. Calculation results indicated that the zeolite addition has rendered PLLA more thermally stable, requiring higher E a values for thermal degradation. ZSM-5 zeolite has shown higher effect on PLLA thermal properties than Hβ zeolite.
