Commentary article in Nature, Vol. 544, Issue. 7649, pp. 155-156, “Make perovskite solar cells stable” Summary of article: Since its inception, perovskite solar cells have achieved quantum leaps in light conversion efficiencies from 2.2% in 2006 to 22.1% in 2016; however, their durability remains significantly less than those of conventional silicon solar photovoltaics. Hence, … More How to make perovskite solar cells more stable?
During my travel around Singapore delivering plastic bags to various shops, I noticed that there is a nascent trend of using carbon fibre as material of construction for cars’ axles and suspension unit. Specifically, while carbon fibre is a strong material capable of withstanding significant amount of load before failure, its catastrophic mode of failure … More Carbon fibre as material of construction for car axle and suspension?
Casting a glance at the types and make of automobiles present on Singapore streets, I realized that cars in the city state is increasingly larger and with bigger engine capacity. Compared to the situation ten years ago, cars in Singapore have indeed gone a step up in weight and size. But, what accounts for the … More Feasibility of using aluminium as an alloy to steel in cars manufacturing
