Exciting liquid metals provide many solutions

Human beings, on average, suffer from the unfortunate propensity to overlook many of the significant objects, issues, and phenomena around them – passing them by as they go about their day. There may be something groundbreaking right before you, but there’s every chance that you won’t actually notice it. This is an especially unfortunate penchant when it comes to solving global problems; the solutions may be right before us, but we often fail to them.

Take the world’s growing energy requirements as an example – with each passing year, the number of power-hungry technologies grows. With it, the need to produce more energy similarly inflates, and yet with our focus based on the technologies, we spend less time looking for sustainable solutions.

When buildings breathe: Nature meets architecture

  • Posted by QEPrize Admin
  • 3 May 2018

Architecture has been borrowing from Mother Nature for millennia. The first structures were made from natural materials; wood, straw, stone and soils. Many common objects that we use today are inspired by plant life too – burdock burs inspired George de Mestral to invent Velcro in 1955, and wind turbines are inspired by the fins of humpback whales!

Today, as engineers face the issues caused by climate change and high energy consumption, they are drawing on nature again to change the way we build our homes and offices.

Jessica Middlemiss: My engineering inspirations

My career in materials engineering and management has been possible through a mixture of hard work and a passion for my subject. However, there have been a few people who have made a big difference to my journey:

Unnamed woman: I met a female chartered engineer on holiday in Turkey at the age of 12. She was so enthusiastic about the application of science through engineering. She inspired me to pursue this career.

My parents: I grew up in rural Dorset as an only child. No one in my family is an engineer. They encouraged me to follow my interest in science. With their support I won a place to study mechanical engineering at Imperial College London.

Dr Sean Crofton:  I failed my first year of mechanical engineering at university. Luckily, my senior tutor, Dr. Crofton, threw me a lifeline: “You passed the materials module easily” he said. “If it interests you, why not study materials instead?” I took his advice, and in doing so I found the branch of engineering where I belong.

Abigael Bamgboye: Finding my passion for materials science

Russian-UK Raw Materials Dialogue in St Petersburg (myself with another Imperial Materials Science student, Chimdi Igwe)

My first encounter with materials science was in a Design and Technology classroom when I was 13 years old. Tasked with designing a product that used ‘smart materials’ (materials that respond to stimuli such as pressure, heat and light), my imagination ran wild with ideas about how we could incorporate this into clothing. My friend and I came up with the concept of the ‘novel bra,’ which could grow with its wearer through puberty. We presented our design with a mini marketing campaign, explaining how the bra could alter its shape in response to changes in skin pH induced by hormones. The project ignited a spark in me to ask why materials behave the way they do.

I thought: ‘Why do glasses shatter? Why are metals strong? How can you design materials that can withstand extreme heat, e.g. in airplane turbines or rocket engines? How can you create nanoporous structures which give you ‘breathable fabrics’?’

Reflecting on displays

Electronically displayed information is everywhere; smartphones, laptops, TV, advertising billboards, wearables… the list of devices we use goes on and on. These displays are mostly based on either liquid crystal (LCD) or organic light emitting diode (OLED) technology. These are great technologies, but they are not without limitations. We have all experienced the poor readability of a phone screen in sunlight and short battery life, largely due to the high power consumption of the display. Recent research has also shown that evening use of these light-emitting devices can negatively affect sleep and next-morning alertness.

So how can we design the next generation of displays to address these issues? A promising approach is to develop displays which can reflect natural ambient light or room lights to illuminate the screen, rather than using the powerful backlighting used in LCDs. Deployed in eReader devices, reflective displays provide vastly improved power consumption and outdoor readability. But this current form of reflective display technology cannot render good colour, nor deliver video rate refresh rates – a major limiting factor to wider application.

Khainza Energy: Creating cleaner fuels to reduce smoke exposure in Uganda

Khainza Energy produces clean, affordable, long lasting cooking gas and packages it in cylinders for sale to low income households in Uganda. The gas is produced entirely from organic waste through biochemical processes. Our gas burns with no smoke, no smell and yet costs less than charcoal!

The idea was inspired by a woman living in Eastern Uganda. She gave birth to her first child when she was barely 16 years old. She now has 6 children, whom she has been providing for almost single handedly. Every morning at 4am, the children awake to the loud sound of an axe splitting firewood. They can hear their mother wheezing and coughing in the small kitchen as she prepares their breakfast. Three years ago, this brave woman was diagnosed with an acute respiratory infection. She had spent a large part of her life effectively “smoking”.
