Bandages light up when in contact with certain chemicals

February 17, 2017

A new ‘living material’—a tough, stretchy, biocompatible sheet of hydrogel injected with live cells that are genetically programmed to light up in the presence of certain chemicals has been designed by a team of engineers and biologists at MIT. In a paper published this week in the Proceedings of the National Academy of Sciences, the researchers demonstrate the new material’s potential for sensing chemicals, both in the environment and in…


Timely diagnosis of serious diseases with smart mobile tool

February 17, 2017

A key challenge for researchers worldwide for decades has been finding practical solutions to detect proteins, cancer biomarkers, viruses and other small objects. These solutions hold promise for saving lives through more timely diagnosis and treatment of serious infections and diseases. Now a UCLA team’s new research shows how such detections might be done for a fraction of the cost by using ‘smart’ mobile devices designed by machine learning. One…


3D printing produces gas turbine blades

February 6, 2017

Siemens has run a successful test of power generation gas turbine blades produced wholly by metal-based 3D printing by UK-based Materials Solutions, which it bought last year. Siemens said on Monday it was the first to test such blades under full-load engine conditions at 13,000 revolutions per minutes and temperatures above 1,250°C (2,282°F). It called the test a “breakthrough”. 3D printing, also called additive manufacturing, involves making a three-dimensional object…

Hydrogel robots go fishing with great success

February 1, 2017

Transparent, gel-based robots that move when water is pumped in and out of them, have been fabricated by engineers at MIT. The bots can perform a number of fast, forceful tasks, including kicking a ball underwater, and grabbing and releasing a live fish. The robots are made entirely of hydrogel — a tough, rubbery, nearly transparent material that’s composed mostly of water. Each robot is an assemblage of hollow, precisely…


Framework to design reconfigurable metamaterials developed

January 19, 2017

Metamaterials—materials whose function is determined by structure, not composition—have been designed to bend light and sound, transform from soft to stiff, and even dampen seismic waves from earthquakes. But each of these functions requires a unique mechanical structure, making these materials great for specific tasks, but difficult to implement broadly. But what if a material could contain within its structure, multiple functions and easily and autonomously switch between them? Researchers…


Tech for the skyscrapers of the future

January 16, 2017

Materials science is always an interesting field of research, looking at novel materials and how they might change the way we live—-or looking at traditional materials but in novel applications. Now Arconic, which does business in engineering materials and solutions, is turning heads with their vision of what future skyscrapers could look like. It is worth thinking about flexible components “that can make buildings more than just static giants,” said…


3D printing technique allows polymers to be added retrospectively

January 13, 2017

By depositing layer upon layer of polymers in a precisely determined pattern, three-dimensional printing technology makes it possible to rapidly manufacture objects. Once these objects are completed, the polymers that form the material are ‘dead’ — that is, they cannot be extended to form new polymer chains. MIT chemists have now developed a technique that allows them to print objects and then go back and add new polymers that alter…


Membrane technology could be transformed with 3D printing

January 13, 2017

Developments in 3D printing techniques could open the door to the advancement of membrane capabilities, researchers at the University of Bath suggest. This work is part of the University’s Centre for Advanced Separations Engineering (CASE) and is the first time the properties of different 3D printing techniques available to membrane fabrication have been assessed. Membranes are a semi-permeable selective barrier that separate the molecules in a mixture within a gas or…


3D printing machine uses liquid metal

January 13, 2017

A liquid metal printing machine that could represent a significant transformation in manufacturing has been invented by a father and son team in the START-UP NY program. A breakthrough idea five years ago by former University at Buffalo student Zack Vader, then 19, has created a machine that prints three-dimensional objects using liquid metal. Vader Systems is innovating and building the machines in a factory in the CrossPoint Business Park in Getzville….
