artificial tooth enamel

11.02.2022

Scientists from Beihang University in Beijing were able to create high-quality artificial enamel. The new material can be used not only in dentistry, but also in the construction of earthquake-resistant buildings, the manufacture of pacemakers, and also for bonding damaged bones.

Tooth enamel is the thin outer layer of teeth and the hardest biological material in the human body. Tooth enamel is an ideal model for developing artificial nanomaterials that mimic the properties of biomaterials, but accurately reproducing enamel is challenging.

Scientists from China have developed an analogue of enamel, consisting of assembled hydroxyapatite nanowires with segments of an amorphous intergranular phase. Artificial tooth enamel has been designed to closely mimic the composition of natural material, replicating the shapes and sizes of biologically found components and the organization of their interfaces.

The scientists tested the new material by applying it to various objects, including human teeth.

The nanocomposite simultaneously demonstrated high rigidity, hardness, strength, viscoelasticity, and toughness, surpassing the properties of enamel and previously manufactured bulk materials based on enamel.

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. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Video in breast pocket 05.06.2002

The Japanese company "Sony" has started production of a subminiature digital video camera DCR-IP5. Dimensions are clear from the photo, weight - 310 grams. The lens is equipped with a tenfold optical zoom, there is also a 12x digital zoom.

A cassette smaller than a matchbox holds an hour of high-quality video (over 500 vertical lines). True, due to the small size of the device, the charge of the standard battery is only enough for 35 minutes of shooting. This means that the entire cassette cannot be removed from one charge. When recording, the MPEG-2 video information compression method developed for computers is used.

Only every 12th frame and information about where and how its individual elements move is recorded on film. When played back, the full picture is restored from this information.
