Bioink for 3D printing of human tissues

13.02.2020

Bioengineers from Rutgers University (USA) have developed "bioink" for 3D printing of materials that could serve as a scaffold for growing human tissues. Printed fabrics can repair or replace damaged human tissues.

In the new system, hyaluronic acid and polyethylene glycol serve as the main "ink cartridges" for 3D printing. Hyaluronic acid, a natural molecule found in many body tissues, has properties that are ideal for creating custom tissue scaffolding, but it lacks the necessary strength. So engineers at Rutgers University used modified versions of hyaluronic acid and polyethylene glycol to make a gel that is strengthened by chemical reactions and acts as a scaffold for tissue growth.

In the future, the new system will have other "ink cartridges" with various cells and ligands, which serve as binding elements for tissue cells. The system will print gel scaffolds with the right stiffness, cells and ligands, depending on the type of tissue to be obtained.

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. ... >>

MCP1811/12 - a family of linear regulators with ultra-low quiescent current 30.12.2019

When developing portable devices, special attention should be paid to the choice of voltage converters. They should be small, have low self-consumption, and have a minimum of passive components in the harness.

Microchip offers a solution - a new family of LDO controllers MCP1811/12.

Despite the UDFN's tiny 1mm x 1mm package, the regulator can deliver up to 300mA of output current. At the same time, the quiescent current is only 250 nA, and in the Shutdown mode it can drop to 5 nA. With these features, the MCP1811/12 is well suited for small, portable, battery powered applications.

The regulators are available with nine fixed standard output voltages: 1, 1,2, 1,8, 2,0, 2,5, 2,8, 3,0, 3,3 and 4.0 V. The voltage drop at 300 mA is 400 mV.

Another feature of the MCP1811/12 is that only one ceramic capacitor with a capacity of 1 uF is sufficient for stable operation. It takes up little space on the board and provides a stable output voltage with minimal noise.

Key features of the MCP1811/12 family:

output current up to 300 mA;
quiescent current 250 nA;
case UDFN 4-lead, SOT-23-3/5, SC70-3/5;
input voltage range 1.8...5,5 V;
output voltage range 1...4 V;
fixed voltage drop (400 mA);
binding from one ceramic capacitor 1 μF (2,2 μF).
