Microneedles represent promising tools for delivery of drugs to the skin. However, before these microneedles can be used in clinical practice, it is essential to understand the process of skin penetration by these microneedles. The present study was designed to monitor both penetration depth and force of single solid microneedles with various tip diameters ranging from 5 to 37µm to provide insi...

Boron-doped diamond granular thin films are known to exhibit superconductivity with an optimal critical temperature of Tc=7.2 K. Here, we report the measured in-plane complex surface impedance boron-doped in microwave frequency range using a resonant technique. Experimentally inductance values good agreement estimates obtained from normal state sheet resistance material. The magnetic penetratio...

The nature of the pairing states of superconducting LaNiC_{2} and LaNiGa_{2} has to date remained a puzzling question. Broken time reversal symmetry has been observed in both compounds and a group theoretical analysis implies a nonunitary triplet pairing state. However, all the allowed nonunitary triplet states have nodal gap functions but most thermodynamic and NMR measurements indicate fully ...

We report the superconductivity of a new quaternary compound ThMo2Si2C, synthesized with arc-melting technique. The crystallizes in tetragonal CeCr2Si2C-type structure cell parameters = 4.2296 Å and c 5.3571 Å. An interlayer Si-Si covalent bonding is suggested by atomic distance. electrical resistivity magnetic susceptibility measurements indicate Pauli-paramagnetic metal dominant electron-elec...

The vacuum of supersymmetric gauge theories (SQCD) with N = 2 softly broken to N = 1 resembles that of a BCS superconductor in that it has a condensate which collimates flux into vortices, leading to confinement. We embed the SQCD vortex into the BCS theory by identifying the N = 1 vector multiplet mass and lightest massive chiral multiplet mass with the Fermi velocity divided by the London pen...

We have synthesized the polycrystalline samples of Eu1-xKxFe2As2 (x = 0-1) and carried out systematic characterization using x-ray diffraction, ac & dc magnetic susceptibility, and electrical resistivity measurements. We have seen a clear signature of the coexistence of superconducting transition (Tc = 5.5 K) with SDW ordering in our under doped sample viz. x = 0.15. The spin density wave trans...

Recently, it has been demonstrated that particulate substances penetrate preferentially into the hair follicles and that the penetration depth depends on the particle size. In the present study, the influence of the vehicle of the particulate substances on the penetration depth was investigated. Four different formulations (ethanolic suspension, aqueous suspension, ethanolic gel and aqueous gel...
