The free energy and conformational properties of a wormlike chain confined inside a spherical surface are investigated. We show that in the weak-confinement limit, the wormlike chain model exactly reproduces the confinement properties of a Gaussian chain; in such a case the confinement entropy dominates the free energy; in the strong-confinement limit, the free energy is dominated by the bendin...

Two different experimental approaches based on ellipsometry and zeta potential measurements have been employed to determine the dispersion and polar surface free energy components of glass. From ellipsometry the adsorption isotherms of n-octane and water have been determined, yielding values for the film pressures of n-octane and water and the dispersion and polar surface free energy components...

The primary aim of this study was to analyse the correlation between topographical features and chemical composition with the changes in wettability and the surface free energy of microstructured titanium (Ti) surfaces. Periodic microscale structures on the surface of Ti substrates were fabricated via direct laser interference patterning (DLIP). Radio-frequency magnetron sputter deposition of u...

The conformation of a polymer on a curved surface is high on the agenda for polymer science. We assume that the free energy of the system is the sum of bending energy of the polymer and the electrostatic attraction between the polymer and surface. As is also assumed, the polymer is very stiff with an invariant length for each segment so that we can neglect its tensile energy and view its length...

Nowadays, appearance is an important factor in vehicles. For this reason, paint application widely used plastic parts. Surface energy a key parameter for the adhesion of on surface polymers. Among thermoplastic polymers, polycarbonate and acrylonitrile butadiene styrene are commonly materials due to their higher energies. low materials, energies can be increased using streamer, plasma, corona, ...

introduction: acute myeloid leukemia (aml) is a clonal disease characterized by heterogeneous involvement of hematopoietic bone marrow cell populations. in aml patients, a variety of clinical and biologic parameters, including surface markers, have been examinedfor potential value in predicting treatment response and survival. by checking the myeloid, lymphoid and nonspecific markers on the bla...
