Early detection of people infected of the novel Coronavirus has become an imminent challenge around the world as the epidemic continues to develop.  A team of researchers from the Hong Kong University of Science and Technology (HKUST) recently invented the world’s fastest portable COVID-2019 detection device.  With the latest microfluidic chip technology, the device can detect the virus in just 40 minutes from sampling to testing, compared to the currently-used polymerase chain reaction (PCR) technology which takes between 1.5 to 3 hours. PCR technology is a molecular biotechnology used to amplify specific DNA fragments for the extraction of viral RNA, and the speed of temperature change is the key that determines the efficiency of the DNA’s amplification process, meaning the faster the temperature rises, the shorter the device can come up with a test result.

Fion LEUNG, a 2010 business administration graduate at HKUST, knew she would not want a long-term career in the financial sector while she was working as an analyst at a global investment bank. Rather, getting more people into volunteering and nurturing children and young people gave her much more satisfaction than advancing her coveted career. She soon branched out and pursued entrepreneurship based around what she thought was meaningful, and sought greater exposure and ideas together with her friend WONG Suet-Yi. While attending networking events to make useful contacts and more friends on the same wavelength, both young ladies felt awkward about approaching industry leaders. And they realized that their feelings were common, like her peers, being fresh out of college and also desperate to build a career but having no mentors they could ask for advice.

From fundamental discoveries to knowledge transfer and application, you can find all the latest breakthroughs we have done in this issue of Research@HKUST.

Graduated with a BSc in Mathematics in 2011, Lancelot SHIR has taken a sweet and varied journey in life. A few years after graduation, Lancelot already had success with his first business — a tutorial center teaching mathematics — which he funded with two years of hard work of working. As a local rock star tutor, it could have been all maths for Lancelot with his tutorial business achieving great results. However, he encountered a health problem in 2017 due to massive work pressure, and his life took an unexpected turn.  “I was suffering from a stomach problem and a friend of mine suggested I used raw honey to treat the problem. It worked a treat and I was suddenly catapulted into the world of honey and bees – I couldn’t stop learning and it changed my life,” he says.

Students attending the classes of Prof. Julian GROVES of the Division of Social Science understand that switching off and putting away their electronic devices is mandatory—even the use of laptops or tablets for note-taking are discouraged—because Prof. Groves reckons that while the internet can be an important resource for educators, “mobile devices can be a terrible distraction to classroom learning”. The students might not like it at first, but they rarely complain about it because they are offered “something equally compelling in return” which involves many interactive activities such as surveys, quizzes, simulations, and discussions to keep them engaged.

A research team led by scientists from the Hong Kong University of Science and Technology (HKUST) unveiled a first-in-kind study of nitrogen oxides (NOx) and its role in the rise and fall of airborne sulfates in hazy air pollution, offering policymakers new insights into ways to tackle smoggy weather.  Dense, hazy fog episodes characterized by relatively high humidity, low visibility and extremely high PM2.5 have been a headache to many megacities including those in Mainland China. Among pollutants that are less than 2.5 microns in diameter (PM2.5), airborne sulfate is one of the most common components of hazy air pollution formed atmospherically via the oxidation of sulphur dioxide (SO2).
