The wetting of droplets plays a critical role in engineering applications. Intensive study on nano-droplets is great significance revealing the characteristics droplets. behavior ethanol/water mixture smooth substrate was investigated through molecular dynamics simulation this paper. Five with different mass fractions placed copper surface energies were simulated to equilibrium at 298.15 K. con...

We propose a novel semiconductor compatible path for nano-graphene synthesis using precursors containing C-Br bonding and liquid catalyst. The unique combination of CBr4 as precursor and Ga as catalyst leads to efficient C precipitation at a synthesis temperature of 200 °C or lower. The non-wetting nature of liquid Ga on tested substrates limits nano-scale graphene to form on Ga droplets and su...

Electrospraying also known as an electrohydrodynamic atomization is a technique for atomizing liquids. The origin of electrospraying is on the base of the charged droplets theory which the interface of the droplets could be deformed by the applied electric field on a liquid droplet which egressing a capillary [1]. Electrospray is a well-known phenomenon which has different applications such as ...

Reactive spinning of nano- and microfibers that involves very fast chemical reactions and ion exchange is a challenge for the common methods for nanofiber formation. Herein, we introduce the reactive magnetospinning method. This procedure is based on the magnetic-field-directed collision of ferrofluid droplets with liquid droplets that contain complementary reactants. The collision, start of th...

ddPCR is a highly sensitive PCR method that utilizes a water-oil emulsion system. Using a droplet generator, an extracted nucleic acid sample is partitioned into ~20,000 nano-sized, water-in-oil droplets, and PCR amplification occurs in individual droplets. The ddPCR approach is in identifying sequence mutations, copy number alterations, and select structural rearrangements involving targeted g...

Magnetodynamical solitons are highly non-linear particle-like textures that derive their stability from an intrinsically dynamical state of their constituent spins. Although magnetodynamical solitons such as spin wave (SW) bullets can be sustained in ultra-low insulating magnetic films, such as YIG, using parametric pumping by external microwave fields [1], the advent of spin transfer torque va...

The dynamical properties of nanogels of xanthan gum (XG) with hydrodynamic radius controlled in a size range from 5 nm to 35 nm, were studied at the different XG concentrations in water/sodium bis-2-ethylhexyl-sulfosuccinate (AOT)/decane reverse micelles (RMs) vs. mass fraction of nano-droplet (MFD) at W = 40, using dynamic light scattering (DLS). The diffusion study of nanometer-sized droplets...

Lipid nanocarriers are considered as promising candidates for drug delivery and cancer targeting because of their low toxicity, biodegradability and capacity to encapsulate drugs and/or contrasting agents. However, their biomedical applications are currently limited because of a poor understanding of their integrity in vivo. To address this problem, we report on fluorescent nano-emulsion drople...

In droplet microfluidics, aqueous droplets are typically separated by an oil phase to ensure containment of molecules in individual droplets of nano-to-picoliter volume. An interesting variation of this method involves bringing two phospholipid-coated droplets into contact to form a lipid bilayer in-between the droplets. These interdroplet bilayers, created by manual pipetting of microliter dro...
