- Andrew WadeSenior reporterAs our readers will know, The Engineer is a very broad church that tries to cover all branches of the vast engineering expanse, from automotive and energy, to chemical and marine. Nonetheless, every once in a while we have a week where one sector tends to dominate. For me this week that sector was aerospace, and there were no complaints coming from my direction.
Aerospace is perhaps engineering’s sexiest façade, the manifestation of humanity’s seemin
- Technology embedded in smartphones is being exploited to develop an in vitro diagnostic testing solution that bridges the gap between multi-step manual lab tests and automated test-specific readers.
The user adds a sample and positions the transparent test cartridge on the smartphone touchscreen. The phone app then confirms the correct positioning, starts the test and prompts the user to carry out specific actions42 Technology’s invi concept – an app that works in tandem with a smart
- Australian researchers have increased photon absorption in a semiconductor to almost 99%, according to the University of Sydney. The absorber is a sub-wavelength thin-film semiconductor, and no complex nano-structures, meta-materials, exotic materials or difficult-to-create metal-non-metal combinations have been used. When light falls on a thin film etched with narrow grooves, light is directed sideways and ...

- This month The Engineer looks back to a very dark day in British history, and the worst rail disaster the UK has ever suffered.
On 22 May 1915, five separate trains were involved in a devastating crash at the Quintinshill signal box near Gretna Green in Dumfriesshire, Scotland.
Gretna Green was the UK’s worst ever rail disasterThe collisions and subsequent fire resulted in the loss of at least 226 lives, although a definitive number of victims has never been established.

- Excessive internet use contributes to the development of school burnout. School burnout, in turn, may lead to excessive internet use or digital addiction, according to research by the Academy of Finland. The findings show that, via school burnout, adolescents’ excessive internet use can ultimately lead to depression. Exposure to digital addiction is most likely to ...

- Texas researchers have created a liquid catalyst for lithium-air batteries, perhaps bringing this weight-saving technology nearer, writes Steve Bush. “There’s huge promise in lithium-air batteries. However, despite the research being done by groups all over the world, those promises are not being delivered in real life,” said professor Kyeongjae Cho. “Our collaboration team has demonstrated ...

- Cloud based software that offers real-time air traffic control for drones, could help address the growing safety concerns prompted by recent “near-misses” its developers have claimed.
Airspace Alerts, designed by software engineers at UK startup Altitude Angel, enables drone operators to specify ‘alert regions’ that the firm’s cloud platform monitors in real-time for low-flying manned aircraft, proactively sending a push notification via email or SMS to the drone op
- “Is this the end of the the semiconductor success story?” asked Infineon CEO Reinhard Ploss at ITF2016 in Brussels this week. “”As Moore’s Law is stalling an overall system optimisation is required to achieve further value-add,” argued Ploss. “The physical limits may be pushed further but commercial limits provide a hard ceiling,” said Ploss, adding ...

- This week’s video comes from the US where an energy saving technique from the natural world is being applied to microrobotics.This is the aim of experts at Harvard University who have equipped their RoboBee with the ability to perch using an electrode patch and a foam mount that absorbs shock.
When the electrode patch is supplied with a charge, it can stick to surfaces that include glass, wood and leaves. To detach, the power supply is switched off.
The patch is said to require around 1000
