Microfluidic paper-based analytical devices (μPADs) have emerged as viable multiplexable platforms with the potential to transcend existing analytical techniques in resource-limited settings. μPADs are fabricated by patterning hydrophobic materials on hydrophilic paper. Reproducibility in fabrication is essential in a myriad of applications and particularly, in the development of point-of-care ...

In this work, the rheological behavior of a group of model crude oils is experimentally studied at temperatures below their wax appearance temperature (WAT). We consider both a two-component wax-oil system and a three-component oil-water emulsion that is partially stabilized by precipitated wax. We characterize the shear-localization and yielding using a combined approach of bulk rheometry and ...

BACKGROUND Qairooti (Cerate), a medicinal salve or ointment, compounded of wax and oil, is a formulation used alone or as a basis for medicinal dosage forms. It is widely used from the ancient times to the present. Based on its structure, beeswax has unique characteristics. It builds stable emulsions and increases water absorbance of creams and ointments. The aim of this study was to gather all...

Polyaniline and polyamide (nylon 6,6) nanocomposites with Silva were prepared by in-situ oxidativepolymerization of aniline monomers in the presence of Ag salt Nano particles of silver (NPs) were symthesieedby controlled reduction of Ag+ ions kith sodium borohydride at room temperature. Nylon 6,6 wax loaded withAg nanoparfieles by erdrapment of Ag+ ions into the polymer network, followed by red...

The localization of cuticular wax (CW) on the leaf epidermis and its interaction with physiological mechanisms three edible aroids, Alocasia, Colocasia, Xanthosoma, were assessed. CW in tissues was visualized using scanning electron microscopy, which higher Colocasia (10.61 mg·dm?2) Xanthosoma (11.36 than Alocasia (1.36 mg·dm?2). exhibited superhydrophobic properties a static contact angle (CA)...

Objectives: Cuspids migrated medially into the position of lateral incisors create unpleasant esthetic appearances. This kind of a situation and the related disturbances such as the diastemas and the positional and/or proportional irregularities, create major challenges in front of the dental practitioners. Materials and Methods: The diagnostic additive wax-up, gingival esthetic recontouring, v...

Wax-based additives can be added to crumb rubber modified bitumen (CRMB) at different stages enhance the workability. This study aims optimize preparation procedure by investigating effects of on rheological properties CRMB containing wax-based and interaction mechanism. Rubber swelling tests under various conditions were conducted examine temperature process. Rheological thermal characterizati...
