Nanoparticles display a very large surface-area. Therefore, coatings of functional nanoparticles adsorbed to a solid substrate yield an enlarged interface per footprint-area which is highly appreciated for probe-immobilization in bio-chip technology [1,2]. Silica nanospheres, equipped [...]

The fabrication of surfaces and films with controlled nanometer features is currently an active area of research. The design of complex nanoarchitectures with novel physical properties has potential applications in many existing and emerging fields [...]
The present study deals with cobalt-doped vanadium oxide thin layers prepared by pulsed laser ablation. Variation of the preparation parameters allows one to synthesize films with a variety of properties. The chemical composition of the [...]
The combination of surface chemistry and roughness on multiple scales imbues enhanced repellency to the lotus leaf surface when in contact with a high surface tension liquid such as water. This understanding has led to [...]
Self-cleaning surfaces have wide applications in architectural and automotive windows and solar panels, etc. The development of superhydrophobic surfaces was inspired by observation of lotus and other plant leaves. Many existing hydrophobic coatings either have [...]
A method consisting of electrochemical anodization and self-assembling of hydrophobic-hydrophilic mixture has been employed to fabricate superhydrophobic sponge-like nanostructured TiO2 surfaces with remarkably controllable adhesion. Water adhesion ranged from ultra-low (5.0 N) to very high [...]
In addition to its civil engineering properties, concrete also has an architectural and aesthetic function. When the concrete structure ages, the visible appearance of the surface gradually changes as it is exposed to the environment, [...]
New titanium alloys with improved biocompatibility have been developed for dental and biomedical applications. The osseointegration of implants depends on surface properties of these alloys; nature of the oxide film at the metal-oxide-bone. Also stress [...]
In this study, the phenomena of nanotube formation on the surface of Ti alloys by electrochemical method. Nanotube layer formed on Ti alloys in 1 M H3PO4 and 1 M H2SO4 electrolyte with small additions [...]
In this paper, Ti-Zr(10, 20, 30 and 40 wt%) alloys were prepared by arc melting and nano-structure controlled for 24 hr at 1000 °C in argon atmosphere. Formation of oxide nanotubes are conducted by anodizing [...]
In the present study, we chose Nb as a binary alloying element because it has excellent biocompatibility and be expected to act as a -stabilizer. The purities of the starting raw materials were 99.99% for [...]
Laser-induced phase transition and sintering of nano-diamond powders (4-8nm) was used to produce a thick (10-50um) strongly adherent nano-diamond/diamond-like carbon (nD-DLC) coatings on aluminum alloy 319. A transition to diamond-like carbon produced a Vickers hardness [...]
When the meniscus of liquid is subject to strong electric field, electric charge is induced on the meniscus and electrostatic force elongates the liquid to form a cone-jet. This electrospray phenomenon can be applied to [...]
Hydrogenated amorphous carbon (a C:H) films are good candidates for biomedical applications, requiring smooth surfaces, biocompatibility and singular tribological characteristics. The addition of elements to a C:H films, such as oxygen, silicon, fluorine or metals, [...]
In order to overcome the sensitivity limitation of SPR, nanoparticle-coupled SPR biosensors have explored since nanoparticles may significantly enhance the sensitivity by 1-2 orders of magnitude. Although the nanoparticle conjugated method contributes to the enhancement [...]
Gold nanoparticles are synthesized by direct reduction of an aqueous solution of the metal salt with a surface regulating polymer N-polyvinyl pyrrolidone (PVP), which bind on the gold surface, insulate the particles from Au3+ and [...]
This paper presents an easy and efficient fabrication method of plastic replicas of micro/nano combined structures using an aluminum stamp with micro/nano combined structures (ASMNCS) on its surface. ASMNCS could be fabricated by two steps: [...]
In this work, we employed MD simulation to investigate the details of the surface structure evolution during high energy Ar bombardment on Pd (001) surface. From the statistical manner by summing up for 1,000 independent [...]
The use of macromolecular scaffolds for hierarchical organization of molecules and materials is a common strategy in living systems that leads to emergent behavior. One characteristic of this strategy is that it generates micron-scale structures [...]
