- Definition(s)
- A sub-microscopic aggregate of molecules. In the context of cleaners, these molecules are surfactants usually arranged in sphere or rod shapes with their hydrophilic ends facing outward into the water solution and hydrophobic ends facing the inside of the aggregate. Micelles can hold hydrophobic oil molecules at their centers to create stable emulsions. Alconox, Inc.
- Example sentence(s)
- Grease and oil are nonpolar and insoluble in water. When soap and soiling oils are mixed, the nonpolar hydrocarbon portion of the micelles break up the nonpolar oil molecules. A different type of micelle then forms, with nonpolar soiling molecules in the center. Thus, grease and oil and the 'dirt' attached to them are caught inside the micelle and can be rinsed away. - About.com
by - Using micelles for cleaning is not a new idea. Common household detergents contain micelles, which dramatically increase the capacity of the washwater to pick up organic contaminants. Micelles could likewise be used to remove organic contaminants from industrial waste streams. - Massachusetts Institute of Technology
by - In a micelle, the tails of the soap molecules are oriented toward and into the grease, while the heads face outward into the water, resulting in an emulsion of soapy grease particles suspended in the water.

- Definition(s)
- Micely jsou shluky molekul tenzidů dispergované v kapalném médiu. Typická micela ve vodném roztoku vytváří agregáty s hydrofilní částí molekuly orientovanou do vodného prostředí a hydrofóbní částí skrytou uvnitř. wikipedia - by David König
- Example sentence(s)
- Hydrofobní konce molekul se snaží minimalizovat kontakt s vodným prostředím, což vede ke tvorbě micel – tvorbou micel se snižuje energie systému. - wikipedia

- Micele su agregati molekula u vodi, sa nepolarnim delovima u unutrašnjosti i polarnim na površini koaj je izložen vodi. Institut tehničkih nauka SANU - by V&M Stanković
- Example sentence(s)
- Masne kiseline sa većim brojem C atoma su praktično nerastvorne u vodi. Njihove Na i K- soli se zovu sapuni. One obrazuju micele u vodi kod kojih he negativan COO- kraj okrenut ka vodi, a nepolaran C- niz je okrenut ka unutrašnjosti micele. U celini micele su naelektrisane negativno i u rastvoru ostaju suspendovane jer se međusobno odbijaju. - Wikipedia
by V&M Stanković - Мало радова обрађује утицај мицела на брзину хемијске реакције. Овде је одабран натријум-додецилсулфат (SDS) као активан тензид, који при одређеним условима гради мицеле. - Универзитет у Крагује
by V&M Stanković - Фундаментална истраживања протеина млека, посебно казеина (утицаја параметара технолошког процеса) применом савремених инструменталних метода, електронске микроскопије, гелелектрофорезе, ултрацентрифуговања и друго резултирала су значајним публикацијама и побудила велико интернационално интересовање научне јавности, дајући нове податке везане за хемију казеинске мицеле. - Univerzitet u Novom Sadu

- misel Alm. Mizelle
Genelde organik yapıda büyük moleküllerin bir araya gelmesiyle oluşan elektrik yüklü kolloidal sistem. Sabun ve diğer deterjanların oluşturduğu kolloidal boyuttaki tanecikler.
BSTS / Kimya Terimleri Sözlüğü (II) 2007 www.tdk.gov.tr - by harun parpucu (X)
- Example sentence(s)
- Sabun molekülü hidrokarbon zinciri nedeniyle suda tam olarak çözünmez, ama miseller oluşturarak suda kolayca suspense olur. misel 5-150 sabun molekülünün hidrokarbon kısmının biraraya geldiği, iyonik ucun suya yöneldiği kümelerdir. - Avantgarde Soaps Marketing blogspot

- Definition(s)
- Micela je guľovitý zhluk molekúl chemických látok, ktoré prejavujú takú či onakú povrchovú aktivitu, v kvapaline. Naznámejšie sú zrejme micely v čistiacich a pracích saponátoch.

- Example sentence(s)
- Jeden typ agregátu sa nazýva micela. Koncentrácia, pri ktorej začína tenzid tvoriť micely vnútri rozpúšťadla, sa nazýva kritická micelárna koncentrácia. - Wikipedia
