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”.

Invisible molecules that make a visible impact

As chemical engineers and chemists, we often don’t get to see what we create – molecules are too small to see and chemical processes often happen in closed systems. As such, when we do get to see the fruits of our labor, the result can be incredibly exciting and motivating.

This was the case in the founding of my company, Sironix Renewables. During my PhD at the University of Minnesota, I worked with a team of scientists to develop new, eco-friendly replacements to existing chemicals and fuels. The process involved making renewably-sourced products, like fuels, detergents, and plastics. Finding a suitable replacement to an existing product is great, but for us the ‘holy grail’ was finding something that worked better than what existed.

One of these ‘holy grail’ moments struck us when we were looking at a set of vials – all but one was filled with a cloudy, white liquid. We were looking at the hard water stability of new detergent molecules for things like spray cleaners and laundry detergents, and the cloudy, white liquid meant it didn’t work well. The one clear vial, however, was our new detergent molecule and it performed flawlessly. This was one of the few moments where we got to see the result of our work.

Engineers create plants that glow

Illumination from nanobionic plants might one day replace some electrical lighting.

Imagine that instead of switching on a lamp when it gets dark, you could read by the light of a glowing plant on your desk.

MIT engineers have taken a critical first step toward making that vision a reality. By embedding specialized nanoparticles into the leaves of a watercress plant, they induced the plants to give off dim light for nearly four hours. They believe that, with further optimization, such plants will one day be bright enough to illuminate a workspace.

“The vision is to make a plant that will function as a desk lamp — a lamp that you don’t have to plug in. The light is ultimately powered by the energy metabolism of the plant itself,” says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT and the senior author of the study.

Materials: the ‘stuff’ that makes up our world

Recent weeks have seen festive engineering in full swing as we constructed wrapping paper masterpieces, calculated how the turkey could fit in the oven and tested out our new gadgets.

The one thing that all our decorations, toys, and even the tape holding everything together, have in common is materials engineering. An often-underrated field, materials engineering brings together countless studies of the ‘stuff’ that makes up our world.

Many of the greatest challenges our world is facing are due to the limits of the materials we have available. By improving how existing materials work, and even creating new ones altogether, we can engineer our future. Throughout January, we are meeting the engineers and innovators who make it their job to get to the bottom of these problems.

A young student who designed a trophy that will be presented to some of the world’s leading engineers has been given a behind the scenes tour of BAE Systems’ advanced manufacturing site where the trophy will be made.

Samuel Bentley, 16, of Prestatyn, Wales, visited the New Product and Process Development Centre (NPPDC) at BAE Systems in Samlesbury, Lancashire, where the company is pioneering world-leading technology to revolutionise manufacturing of military aircraft.

Bradley Olsen: Designing polymers with novel features

Chemical engineer seeks to develop and understand materials that behave in radically new ways.

Anne Trafton | MIT News

Tiny sensors made of antibodies, protein nanospheres that can clean up toxic spills, and gels that could be injected into a wound to initiate healing are just a few of the innovations emerging from Bradley Olsen’s lab at MIT.

Olsen’s research is based on exploring the physical properties of new types of polymers, and taking advantage of those properties to design novel materials that could have many useful applications.

Chocolate design – who said precision engineering is boring?

It’s not all Willy Wonka and Oompa Loompas you know. Designing chocolates is serious engineering. Just like when you made jelly as a child (or adult!), every chocolate shape is made by a mould and every mould is created by forming plastic around a metal ‘tool’.  As a result, making ‘tooling’ is at the heart of the chocolate industry.

Leigh Down, Managing Director at DPS Designs, helped bring the M&S Easter egg ‘Bendy Bob’ to life. “As you can see from our bendy friend, it can be a lot of fun and be really creative,” he said. “But behind this fun stuff is a team of engineers who need to be able to make tooling to the nearest 10 micron. That’s about five times thinner than a strand of hair!”

The team at DPS Designs have been honing their craft for over 20 years. Based in the Forest of Dean, we pride ourselves on using creativity and innovation to create fun chocolates. We challenge you to name something that we haven’t worked out how to mould in chocolate!
