Science for Thought January/February 2018 is out! 

We would like to apologise for publishing this only after the 28th of February due to other complications. February had been a hectic month with lots of things and events happening.  Thank you for understanding.

Click here for the newsletter.

This will be the last newsletter published by the current YSF committee and will soon be taken over by the next YSF committee of 2018/2019. I hope with this, our beloved readers would be able to enjoy one last newsletter from us. We would like to express our gratitude for always keeping up and supporting us.

As usual, we have prepared a quiz for everyone to enjoy and try out!

This newsletter features a very special interview with the high achievers of the latest ‘A’ level Examination of 2017. We would like to emphasise this area in hopes that every other future ‘A’ level exam takers would gain something from reading about it.

Stay tuned and look forward to what our next batch of YSF committee of 2018 has to offer! 

Thank you, everyone.

Kind regards,

PTET YSF team 2017/2018



PTET Science for Thought newsletter utilises digital approach to journalism

Exclusive coverage by the fellas at New Brunei Daily, as part of His Majesty’s visit to PTET last month.

As part of one of the co-curricular activities organised by students of Pusat Tingatan Enam Tutong (PTET), a student committee known as the Youth Science Forum (YSF) share their innovative ideas and scientific knowledge through a series of articles published in their yearly school newsletters called ‘Science for Thought’. The newsletter takes on a greener approach to news publications, as their stories are promoted digitally on their school website.

His Majesty listens to YSF showcase

Tuesday, 20.2.2018

The New Brunei Daily (NBD) did an extensive review for the YSF as part of the visit. 

The PTET Youth Science Forum (YSF) was honoured to have been selected to present to His Majesty about our achievements over the past years. Everyone involved was awe struck by how much His Majesty wished to know more about the forums, the newsletters (going digital) as well as summary of our previous endeavours (Science Outreach with primary school students and also the annual symposiums).

Boost for Solar Cells Also Makes Self-Driving Cars Safer


Engineers working to make solar cells more cost effective ended up finding a method for making sonar-like collision avoidance systems in self-driving cars.

The twin discoveries started, the researchers say, when they began looking for a solution to a well-known problem in the world of solar cells.

Solar cells capture photons from sunlight in order to convert them into electricity. The thicker the layer of silicon in the cell, the more light it can absorb, and the more electricity it can ultimately produce. But the sheer expense of silicon has become a barrier to solar cost-effectiveness.

So the engineers figured out how to create a very thin layer of silicon that could absorb as many photons as a much thicker layer of the costly material. Specifically, rather than laying the silicon flat, they nanotextured the surface of the silicon in a way that created more opportunities for light particles to be absorbed.

Their technique increased photon absorption rates for the nanotextured solar cells compared to traditional thin silicon cells, making more cost-effective use of the material.
