In dit artikel, verschenen in TexPress (augustus 2014), besteedt Anton Luiken, lid van de Kenniskring Smart Functional Materials van Saxion en directeur van Texperium, aandacht aan ReBlend. ReBlend is een Nederlands upcycling-initiatief om van textielafval van bepaalde samenstelling door mechanische recycling nieuwe g…
Uranex Ltd is a company on the rise. Since diverting its attention from uranium and coal in early 2013, the company has been 100% focused on developing its Tanzanian Nachu graphite project, which it first discovered during a regional exploration programme in 2012.
Abstract : Numerous functionalized carbon nanotube materials, utilizing a variety of means, were prepared and characterized with respect to their charge storage capability. These materials exploit the high surface area and dc conductivity of carbon nanotubes, while introducing a pseudo-capacitive charge storage mechan…
Telah dipelajari kitosan sebagai inhibitor korosi pada kaleng tinplate dalam media 3% NaCl menggunakan metode pengurangan berat dan polarisasi potensiodinamik. Pada penelitian ini kitosan yang digunakan hanya larut dalam media asam organik, contohnya asam asetat. Tetapi akibat penggunaan asam asetat ini berpengaruh te…

In this paper, a computation model is proposed to study the growth diffusion of two layers (FeB/Fe2B) of St41 low carbon steel during the powder pack boriding in the temperature of 9000C fo 8 hours of treatment time. This computation model based on the Fick’s Law was solved under the certain assumptions with the parab…
Phase-change metamaterials combine the sharp resonant dispersions afforded by metamaterials with the optical switching characteristics of phase-change chalcogenides to create a high-contrast, non-volatile planar optical modulator. Spectroscopic ellipsometry was used to accurately determine the highly-contrasting compl…
Industri kecil yang memproduksi pagar teralis, saat ini masih menggunakan alat manual dalam proses pembuatan bentuk profil teralis, sehingga memakan waktu yang cukup lama dalam pembuatannya. Maka untuk lebih mempermudah proses pembuatan dan menghemat waktu produksi dibuat mesin fence bender untuk membuat bentuk profil…
The results of experimental researches obtained for a varistor ceramics on the basis of zinc oxide are reported. The influence of the sintering time of the ceramics on its electric properties and microstructure is studied. The increase in the sintering time of ceramics is found to result in a broadening of the grain d…
Accurate detection, tracking and classification of micro structures through high speed imaging are very important in many biomedical applications. In particular, visualization and characterization of hydrodynamic cavity bubbles in breaking kidney stones have become a real challenge for researchers. Various micro imagi…

Di Indonesia banyak pengusaha yang membutuhkan kelapa sebagai bahan dasar produksi dan membutuhkan jumlah kelapa yang tidak sedikit. Jika proses pengupasan batok kelapa dilakukan dengan cara menggunakan sabit/berang itu akan menghabiskan waktu, jadi dengan adanya mesin pengupas batok kelapa akan sangat membantu menghe…
The thermodynamics properties of pure epoxidised natural rubber (ENR-50) and epoxidised natural rubber/N, N-M-Phenylenebismaleimide (ENR-50/HVA-2) compound were measured by differential scanning calorimeter (DSC) at a heat rate 10 K/min and at temperatures ranging from 273.15 to 453.15 K. The equations and values of h…
Die Versteifung von Flächen ist in der Entwicklung und Konstruktion eine vielfach zu \n \nbewältigende Herausforderung. Die Schalenstrukturen von Planktonorganismen, sogenannten Diatomeen, \nwerden als Inspiration für neue Lösungen dieser Herausforderung untersucht. Der bionische Prozess \nresultiert in vier von Diato…
In this work we report the results of structural and electrical characterization realized on zinc oxide single crystal samples with (001) orientation, which were doped with antimony. Doping was carried out by antimony thermal diffusion at 1000 °C for periods of 1 and 2 hours under nitrogen environment from a solid sou…
The use of flexible fuels has been increased during the last years making essential to run compatibility tests with those materials exposed to them. In this work the effect of the flexible fuels M15A (Volume Mixture of 85% fuel C and 15 % Aggressive methanol) and M30A (Volume mixture of 70% fuel C and 30 % Aggressive…
Kennedy Space Center scientists developed a hydrogen leak sensor utilizing a combination of chemochromic pigment and polymer that can be molded or fiber spun into rigid or flexible shapes such as tape. The sensor turns a dark color when exposed to hydrogen gas. This sensor has proven to be very effective for pinpointi…
We report magic angle spinning, dynamic nuclear polarization (DNP) experiments at magnetic fields of 9.4 T, 14.1 T, and 18.8 T using the narrow line polarizing agents 1,3-bisdiphenylene-2-phenylallyl (BDPA) dispersed in polystyrene, and sulfonated-BDPA (SA-BDPA) and trityl OX063 in glassy glycerol/water matrices. The…
Porfirin merupakan suatu makromolekul organik yang memiliki potensi sebagai zat pemeka cahaya. Sehingga senyawa ini dapat digunakan pada aplikasi optoelektonik, sebagai alat organic photovoltaic dan elektroluminesensi. Namun, deposisi senyawa porfirin pada permukaan film tipis bukan hal yang mudah karena interaksi yan…
