Epoxy resin dispenser. Tips for a modeller

Modeling

As you know, epoxy glue consists of resin and its hardener. Before use, they are mixed in a ratio of 8: 1 by volume - and this mass turns into a solid synthetic material after three to four hours.

Measuring resin and hardener is easy when it comes to a large enough amount. But at home, sometimes only a few drops of glue are required, and therefore it is difficult to maintain the necessary proportion. We advise you to make the simplest dispenser from two medical syringes with a ratio of their diameters of about 1: 2,8 - 2,9. In this case, it is enough to cut the ends of standard needles and connect them, as shown in the figure. The syringe rods are replaced with new ones bent from steel wire with a diameter of 4 mm. The dispenser is ready.

Epoxy Resin Dispenser

To make a portion of the glue, squeeze the required amount of components onto a clean, dry surface and mix them thoroughly with a wooden or glass stick.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

3D graphene 08.02.2014

Xuebin Wang and Yoshio Bando of the Japan International Center for Nanoarchitectonics of Materials (WPI-MANA) together with colleagues from Japan and China have created a new method for obtaining 3D graphene using bubbles inflated in a glucose polymer solution. The resulting 3D graphene has stability and excellent conductivity.

Graphene plates are very strong, light and have excellent conductivity. Theoretically, macroscopic bulk graphene assemblies should retain the properties of nanosized graphene flakes. However, in recent attempts to create 3D graphene, weak conductivity has been obtained, caused by poor contact between graphene plates. Loss of strength was also a problem, and self-sustaining 3D graphene had not yet been created.

Inspired by the ancient culinary art of "inflated sugar", Bando and his team proved that the compressed, coherent nature of the bonded bubbles would have an impact on strength and conductivity if graphene could be structured in the same way. Scientists have created a syrup from ordinary sugar and ammonium chloride. They heated the syrup to produce a glucose-based polymer called melanoidin, which was then inflated into bubbles using the gases released by the ammonium. The team found that the best quality of the final product is obtained by balancing this stage of ammonium decomposition and glucose polymerization.

As the bubbles grow, the remaining syrup flows off the walls of the bubbles, leaving the intersections of the three bubbles. Upon further heating, deoxidation, and dehydrogenation, melanoidin gradually graphitizes to form "compressed graphene" - a coherent 3D structure consisting of graphene shells bound by the structure of compressed graphene, which, respectively, is formed from the original bubble walls and the intersection framework.

The bubble structure allows the free movement of electrons through the network, which means that the graphene remains completely conductive. In addition, the mechanical strength and resilience of 3D graphene proved to be exceptionally high - the team was able to compress it to 80% of its original size with very little loss in conductive properties or stability.

Expanding on their discovery, Bando and his team in their lab consistently produced $3/gram compressed 0,5D graphene. With low cost and high scalability, the new method can find many applications in engineering and electronics. The product obtained in large quantities was selectively applied in a high-efficiency supercapacitor. Its maximum energy density has become the highest among graphene 3D water supercapacitors - 106 W/kg. This opens up incredible prospects for the rapid development of electric transport and aviation.
