In all tool making processes the reliable form and geometry measurement of highly reflective components is a crucial demand. InfiniteFocus® allows complex details such as steep flanks, cutting angles and cutting edge radii to be quickly and reliably measured irrespective of reflectivity. Even across large areas with a high vertical and lateral scanning range or at complex geometries such as tool-tips, InfiniteFocus® yields robust surface measurement results. Also, due to the use of an additional rotation system parameters such as circular spacing, release angle or other production relevant parameters in milling and drilling processes are measured. The optical form measurement of cutting tools with InfiniteFocus® increase durability, feed rates and overall machining properties.

Today both, paper manufacturers and the printing industry miss the possibility to correlate the visual appearance of a papers’ surface with robust and accurate 3D measurements, even though the correlation of the surface and its printability reflects an increasing need in quality assurance.This strong requirement is met by InfiniteFocus®. The system provides the highly accurate 3D measurement and 3D true color visualization of the surface. This unique combination of 3D data and full color information opens new possibilities in quality assurance as the direct correlation to a papers’ printability. The system is used for surface measurement of both,coated and uncoated paper.

InfiniteFocus® provides unique solutions to various medical device applications. In pharmaceutical tablet manufacturing the optical system is utilized to inspect tablet surface deviation and counterfeit surface registrations with its full 3D surface scanning capability.

The understanding of tribological processes such as friction and wear analysis is essential for the optimisation of many mechanical processes. In contrast to conventional methods, which are based on the analysis of 2D data,InfiniteFocus® provides numerical quantification and detailed 3D surface characterization. In e.g. wear analysis, the optical system allows easy and reliable abrasion measurement of thin coat. Depth, thickness of the coat as well as the true wear-volume of artificially produced crates are measured. Corroded surfaces can be studied through volumetric material oxidation rate determination.

Electronic components have to be faster,stronger and more compact to meet the increasing industrial requests. Regardless of their use in the automotive sector,medical device development or telecommunication,manufacturers have to face continuously growing requirements in terms of density, complexity, reliability and durability of electronic devices. These demands can only be realized throughout consistent and state of the art quality assurance as provided with InfiniteFocus®.

Today, robust and accurate quality assurance is essential for efficiency in the production environment, but, at the same time, there is an increasing need for automation, flexibility and cost control. Alicona Imaging, leading supplier in optical measurement and inspection, offers with InfiniteFocus an optical 3D measurement system, which has the ability to measure steep flanks and the topography of inhomogeneous surfaces with varying reflectivity to an accuracy of 20 nm vertical resolution. As it can be used for surface studies in the lab as well as a measurement tool during production, it is a very cost effective solution for measurements in the micro and nano range.

The quality of indexable inserts is highly dependent on their geometry and surface properties. Durability, feed rates and overall machining properties are influenced by the cutting geometry such as cutting angle and radius. Traditionally, quality assurance methods for geometry accuracy have been restricted to tactile methods. However, tactile measurement devices do not allow the measurement of specific radii or angles due to the mechanical contact of the stylus to the surface. The optical 3D measurement device InfiniteFocus removes inaccuracies caused by tactile inspection methods. It provides highly accurate measurement of angle and profile plus the additional functionality of roughness, waviness. Also, the analysis of faults such as pits, scratches and contamination is possible. Due to the optical inspection quality, output and tool durability become approved.

Currently technology to utilize laser pulses for the treatment of hard tooth structure is in well underway. Research and development efforts by the Dental Sciences and equipment manufacturers have placed great emphasis on the need to develop accurate methods to characterize and guide the development of this new method of dental treatment. Infinitefocus microscopy is a method of imaging and quantifying microscopic three- dimensional features. This unique optical reconstruction technique is referred to as “Topomicroscopy”. It is ideally suited to the evaluation of laser (and conventional) dental drilling procedures because of its ability to produce geometricallyaccurate, 3D color images and the corresponding volumetric data sets of drilled dental surfaces.

Surfaces with steep flanks and varying reflective properties are usually not measurable with conventional surface measurement techniques, even though there is an ongoing miniaturization of components and rising demand for automation in industry. A solution can be provided by “Focus Variation”, a new optical measurement technique that allows the robust measurement of complex surfaces with vertical resolutions up to 10 nm. In addition to topographic data, true colour information that is perfectly registered to the height data is obtained. The optical 3D measurement device “InfiniteFocus” is based on this new technology and provides a significant improvement in quality assurance. Allowing surface measurements in the micro and nano range as well as relatively large components, the Instrument can be used in the lab and as a measurement tool during production.

The way that the conformation of a liquid drop adhering to a circular, cylindrical fiber changes when the contact angle is increased from a low initial value is discussed in terms of the classical Laplace excess pressure in the drop. It is shown that an axially symmetrical conformation becomes metastable when the contact angle exceeds a critical value which is dependent on the fiber radius and the drop volume. Beyond this point an axially unsymmetrical conformation is favored. The transition between conformations is accompanied by a reduction in the drop/fiber contact area over and above that expected from the contact angle increment bringing about the metamorphosis. The transition described corresponds to the classical roll-up process of detergency first described by N. K. Adam.

We describe the fabrication of roselike microstructures by the direct in situ hydrothermal synthesis method. The as-prepared roselike microstructure film exhibits excellent superhydrophilic properties, absorbing a water droplet of 4 íL in less than 40 ms. Moreover, after a further modification with a self-assembled monolayer of octyltrimethoxysilane, the film changes its wetting properties from superhydrophilicity to superhydrophobicity with a contact angle as high as 154° and a tilt angle lower than 3°.

This paper describes the fabrication of surfaces with different wettability, superhydrophobic/superhydrophilic, and pH-responsive properties. We used a self-assembled monolayer (SAM) of a dendron thiol as the underlying surface for electrodeposition of gold nanostructures. After this modification with a SAM of n-dodecanethiol or 11-mercaptoundecanol, the surface shows remarkable superhydrophobic properties with a contact angle of about 155° and a tilt angle of less than 2° or superhydrophilic properties with a contact angle of about 0°, respectively. Moreover, a large-scale pH-responsive surface was obtained by modification with 2-(11-mercaptoundecanamido)benzoic acid (7) (MUABA). The pH-responsive behavior was amplified by using rough surfaces.

Chitosan nitrate (CTS-HNO3) as an electrorheological (ER) material was synthesized by a simple method. The nontoxic and facile chitosan (CTS) as a substrate of the materials, as well as nitric acid were chosen as starting materials. The ER properties of the suspensions of the CTS and CTS-HNO3 materials were researched. The CTS-HNO3 suspension has much better ER performance than the CTS suspension. The ER effect (relative shear stress, τr = τE/τ0) of the CTS-HNO3 suspension (25 wt%) in silicon oil under a dc electric field reached 94 at a shear rate of 14.5 s−1,which is eight times higher than that of the CTS suspension, where τE and τ0 are the shear stresses at the electric field strengths of 4.2 and 0.0 kV/mm, respectively. The formation of chitosan nitrate helped to decrease effectively the shear stress at zero electric field, and to enhance the ER effect of chitosan material markedly. The influence of the surface energy, conductivity, dielectric constant and dielectric loss tangent on the ER property of the particle materials was investigated, and the results indicate that surface energy played a predominant role. Moreover, the magnitude of the ER effect of the CTS-HNO3 suspension was closely related to the shear rate. In addition, the chitosan nitrate had better thermal stability. The properties of CTS-HNO3 are advantageous in its application as an ER material.

Novel electrorheological materials based on crosslinked chitosan doped with Y2(CO3)3 were synthesized with biocompatible chitosan as the substrate of the materials. The electrorheological performance, surface energy, and thermal decomposition behavior of the materials were investigated as functions of the composition change. The results show that doping Y2(CO3)3 can improve effectively the electrorheological performance of crosslinked chitosan with the formation of a metal–polymer complex when the doping degree is suitable. The surface energy plays an important role in influencing the electrorheological properties of the material.

Using the contact angle measuing unit OCA20 with the SCA22 software and the pendant drop method results in a quick and easy way of charaterizing the netwoking properties of a liquid. The upper surface tension is directly accessible and the polar and dispersed components can easily be calculated after determining the outer surface tension compared with a non polar liquid. In the case of the frequently used solvent DPM the previously unknown polar and dispersed components of the upper surface tension were established, knowledge of which for many networking processes e.g.coatings is of decisive impoutance.

Water striders (Gerris remigis) have remarkable non-wetting legs that enable them to stand effortlessly and move quickly on water, a feature believed to be due to a surface-tension effect caused by secreted wax1–3.We show here, however, that it is the special hierarchical structure of the legs, which are covered by large numbers of oriented tiny hairs (microsetae) with fine nanogrooves, that is more important in inducing this water resistance.

Self-Assembly of Large-Scale Micropatterns on Aligned Carbon Nanotube Films The fabrication of well-defined structures with nanoscale materials is a key technology,[1] and self-assembly is an efficient and often preferred process to build micro- and nanoparticles into ordered macroscopic structures.[2] As carbon nanotubes are attractive materials for nanotechnology because of their interesting physicochemical properties and molecular symmetries,[3–6] it is necessary to control the architecture of carbon nanotubes on the substrates. Most patterned carbon nanotubes are formed on prepatterned substrates or prepatterned catalysts during the fabrication process.[7–9] Herein we report the first use of a long-range force (capillary force) in the self-assembly of three-dimensional (3D) micropatterns on aligned carbon nanotube films through a water-spreading method after the growth of the carbon nanotube. It is considered that low-density regions or vacancies of carbon nanotube films play an important role in the formation of the pattern. Therefore different kinds of highly ordered micropatterned structures have been built in a controlled fashion by introducing vacancies artificially. (请下载全文欣赏)

Controlling Pore Size and Wettability of a Unique Microheterogeneous Copolymer Film with Porous Structure We have fabricated a mesoporous copolymer thin film whose surface pore size can be varied from submicrometer to micrometer. Our fabrication method requires microphase separation induced by a silicone surfactant during the rapid solvent evaporation and polymerizations. The sample films were characterized with atomic force microscopy (AFM), confocalRamanspectroscopy, X-ray photoelectron spectroscopy (XPS), in situ infrared (IR), attenuated total reflection (ATR), and other techniques. The characterization results show that the pore size can be controlled by altering the concentration of silicone surfactant. Furthermore, the mesoporous copolymer film with hydrophobic convex and hydrophilic concave structure exhibits both hydrophobic and oleophobic properties. The unique properties can be attributed to the special heterogeneous porous structure of the polymer film. The resulting porous polymer films can be utilized in many fields, such as self-cleaning, antiadhesives, adsorption, and separation. These mesoscale-patterned surfaces can also provide a model system for investigating the interface properties of actual surfaces. （请下载全文欣赏）
