The present study reports the synthesis of ZnO-NPs using Acantholimon serotinum extracts followed by characterization and evaluation of biological activities. The X-ray diffraction analysis confirmed the synthesis of highly pure ZnO NPs with a hexagonal shape and a crystalline size of FT-IR confirmed the presence of phytocomponents in the plant extract, which was responsible for nanoparticle synthesis. The well diffusion method did not show effective growth inhibition activities of the ZnO-NPs against bacteria.

Synthesis, Characterization, and Spectroscopic Properties of ZnO Nanoparticles

Government Kalasala, Jangareddygudem , India. ZnO nanoparticles have been synthesized by precipitation method from Zinc nitrate. The powder was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, selected-area electron diffraction, UV-vis optical absorption, and photoluminescence spectroscopy analyses. XRD patterns showed that ZnO nanoparticles have hexagonal unit cell structure. The synthesis method has potential for application in manufacturing units due to ease processing and more economical reagents. Nowadays, there has been an increasing demand for the development of nanosized semiconductors due to their significant electrical and optical properties which are highly useful in fabricating nanoscaled optoelectronic and electronic devices with multifunctionality [ 1 — 3 ].

In this work, nanoparticles of zinc oxide ZnO-NPs were synthesized using acetic acid, ethanol and ethylene glycol as solvents. To determine the physicochemical and structural characteristics of the synthesized nanoparticles, IR spectroscopy, X-ray diffraction, UV—Vis spectroscopy and transmission electron microscopy were used. The band gap of ZnO-Nps depends of synthesis solvent used: 3.

Zinc oxide nanoparticles were synthesized using a simple precipitation method with zinc sulfate and sodium hydroxide as starting materials. The synthesized sample was calcined at different temperatures for 2 h. SEM images show various morphological changes of ZnO obtained by the above method.

Беккер последовал в указанном направлении. Он очутился в огромной комнате - бывшем гимнастическом зале. Бледно-зеленый пол мерцал в сиянии ламп дневного света, то попадая в фокус, то как бы проваливаясь. Лампы зловеще гудели. На стене криво висело баскетбольное кольцо. Пол был уставлен десятками больничных коек.

Должен быть способ убедить его не выпускать ключ из рук. Мы обязаны утроить самое высокое сделанное ему предложение. Мы можем восстановить его репутацию. Мы должны пойти на. - Слишком поздно, - сказал Стратмор.

 - С руки Танкадо исчезло кольцо.

El cuerpo de Jesus, el pan del cielo. Молодой священник, причащавший Беккера, смотрел на него с неодобрением. Ему было понятно нетерпение иностранца, но все-таки зачем рваться без очереди.

 Говорите. - Где мой ключ? - прозвучал знакомый голос. - Кто со мной говорит? - крикнул Стратмор, стараясь перекрыть шум.

Она глупейшим образом попала в ловушку, расставленную Хейлом, и Хейл сумел использовать ее против Стратмора. Она понимала, что коммандер заплатил огромную цену за ее избавление. - Простите меня, - сказала .
