SignificanceThe pinch-off of a liquid drop extruded from a nozzle is a canonical situation that involves a series of self-similar regimes ending in a finite-time singularity. This configuration allows for exploring capillary flows over a large range of scales. In the case of suspension drops, the presence of particles breaks the self-similarity by introducing a length scale that can be much larger than the particle diameter. This length scale is a signature of the heterogeneities and delimitates a regime, in which a continuum approach of a suspension can be used from a regime where the discrete nature of the particles is involved.

In addition to the basic and main parts of hospital equipment, 316 L stainless steel is widely utilized in futures such as nails and screws, wires and medical bone clips, dental implants, heart springs (stents), needles, surgical scissors, etc. In the present study, the electrophoretic deposition of a composite based on chitosan (CS), gelatin, nano and microparticles of hydroxyapatite on a 316 L stainless steel substrate was investigated. Hydroxyapatite particles are added to it due to the ossification abilities of steel and due to an enhanced adhesion and bone production, CS and biocompatible gelatin polymer particles were also added to hydroxyapatite.

Fungal keratitis (FK), a severe eye infection that leads to vision impairment and blindness, poses a high risk to contact lens users, and remains the most common underpinning fungal pathogen in temperate climates. Patients are initially treated empirically (econazole 1% drops hourly for 24-48 h), and if there is no response, amphotericin B (AmB) 0.15% eye drops (extemporaneously manufactured to be stable for a week) are the gold-standard treatment.

Human eyes have the most complex and advanced physiological defense barriers. Due to these barriers, efficient delivery of ocular drugs is a major challenge in the treatment of eye diseases and disorders. Posterior eye diseases such as retinopathy are the leading causes of impaired vision and blindness globally.
