Materials Sciences

Materials management deals with the research, development, manufacturing and processing of raw and industrial materials. Key aspects here are biological and medical issues, which play an increasingly important role in this field.

innovations-report offers in-depth articles related to the development and application of materials and the structure and properties of new materials.

Lithium battery cathodes being made using novel sol-gel method

Preparation and characterization of Li1-xNi1+xO2 powder used as cathode materials

Lithium batteries increasingly permeate our lives in all manner of electrical devices. Researchers from Thailand report on a study that investigates the use of the sol-gel method to produce battery cathodes from a new material. They describe their findings in the online materials journal AZojomo*.

For some time LiNiO2 has been a promising cathode material due to its large discharge capa

Motorcyclists keep their cool

A motorcycling jacket using space technology is on hand to chill MotoGP riders racing this weekend in Malaysia and next weekend in Qatar, should the heat require it.

The Anatomic Intercooler System (AIS) jacket was developed by Italian bike clothing company Spidi and was used last year by Spanish rider Sete Gibernau at the world’s hottest motorbike Grand Prix at the Sepang circuit in Qatar.

It keeps the rider cool inside the suit, helping to maintain a low body temperature

World’s smallest universal material testing system

The design, development and manufacturing of revolutionary products such as the automobile, airplane and computer owe a great deal of their success to the large-scale material testing systems (MTS) that have provided engineers and designers with a fundamental understanding of the mechanical behavior of various materials and structures.

In the world of nanotechnology, however, where the mechanical characterization of materials and structures takes place on the scale of atoms and

Helping Out a High-Temperature Superconductor

Researchers at the U.S. Department of Energy’s Brookhaven National Laboratory have discovered a way to significantly increase the amount of electric current carried by a high-temperature superconductor, a material that conducts electricity with no resistance. This is an important step in the drive to create superconductor-based electric and power-delivery devices, such as power transmission lines, motors, and generators. The results are explained in the September 12, 2005, online edition of

Hygienic surfaces, biocidal and self-cleaning coatings

Microbian evolution on a wide variety of surfaces can produce phenomena such as corrosion, dirt, smells and even serious hygiene and health problems.

It is well known there is a great interest in the design and development of the so-called “hygienic surfaces”, referring to surfaces that not only provides biocidal activity but also to those that are easy to clean and even self-cleaning.

Achieving these properties on a surface is possible by means of coatings and treatments

The ESRF tests the hardest and least compressive material in the world

Nanorods of many materials are proving very successful, and their properties often exceed that of nanotubes, making them excellent candidates for industrial applications. Theoretical calculations predicted that diamond nanorods too would have properties superior to that of carbon nanotubes. But, so far, nobody had been able to actually synthesize diamond nanorods. This is no longer true. A team from the Bayerisches Geoinstitut (Universität Bayreuth) has just reported the synthesis of these aggregat
