Vanadium flow batteries (VFBs) are promising for stationary large-scale energy storage due to their high safety, long cycle life, and high efficiency.

The cost of a VFB system mainly depends on the VFB stack, electrolyte, and control system. Developing a VFB stack from lab to industrial scale can take years of experiments due to complex factors, from key materials to battery architecture.

Novel methods to accurately predict the performance and cost of a VFB stack and further system are needed in order to accelerate the commercialization of VFBs.

Recently, a research team led by Prof. LI Xianfeng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences proposed a machine learning-based strategy to predict and optimize the performance and cost of VFBs.

“We use AI technology to

Televising school sport could put too much focus on performance, a price too high for young athletes

A new deal to televise and live stream more secondary school sports in New Zealand has attracted significant attention and debate.

First XV secondary school rugby in New Zealand has been televised for some time on Sky Sport. The attraction of new revenue for broadcasters and other sporting organisations is clear, but what might the cost be for young athletes?

The new broadcast deal is a collaboration between the New Zealand Sport Collective (created by former Olympic rowing champion Rob Waddell and representing more than 50 sports) and Sky Sport Next, a YouTube channel run by Sky TV.

The deal evolved after consultation with several bodies including the New Zealand Secondary School Sports Council (NZSSSC), which coordinates secondary school sport.

It is easy to understand why some school students would like to be on television. But there are moral and ethical issues that need to be considered by those charged

Technology can boost your consistency and performance

When most golfers think about custom fitting, they think about drivers. The experience can be magical. A player and a trained fitter tinker with different head and shaft combinations, tweak lofts and adjust moveable weights. Presto, the ideal combination adds 15 yards of distance off tee and the golfer is hitting straighter shots.

Putter Fitting

Putters, on the other hand, rarely come to mind. That’s a huge mistake. Elite golfers will use their driver, typically, fewer than 10 times in a round but roll 27 to 30 putts. Weekend players may reach for their driver more often than pros, but they putt more too, often up to 35-40 times per round. A custom fit putter that augments your natural stroke can enhance your chances of performing better on the greens and lower your scores.
