USAJOBS Being Made More User Friendly

USAJOBS, the federal government’s website for job openings, is being revised to make it easier to find and apply for openings.

More than 500 federal agencies use USAJOBS to

post job opportunities covering over 600 occupations ranging from student and entry-level jobs to federal executive positions.

Last year in excess of 325,000 jobs that received 17.5 million applications were posted on the site.

Early in this federal fiscal year, which started the first of this month, the portal is planned to include a job status indicator for each listing that would include the number of applicants, the when the job was filled and other information, according to a new report from the Government Accountability Office on the site.

The change would improve transparency and accountability and provide applicants with updates at each stage of the hiring process, the Office of Personnel Management, which runs the site, told GAO.

New findings pave the way to environmentally friendly supercapacitors — ScienceDaily

Limited safety, sustainability and recyclability are key drawbacks of today’s lithium-ion battery technology, along with restricted availability of starting materials (e.g. cobalt). In the search for alternative electrochemical energy storage systems for use in e-mobility and for storing energy from renewable sources, a combination of battery and capacitor is very promising: the “hybrid supercapacitor.” It can be charged and discharged as quickly as a capacitor and can store almost as much energy as conventional batteries. In comparison to the latter, it can be charged and discharged much faster and much more frequently: while a lithium-ion battery achieves a service life of a few thousand cycles, a supercapacitor manages around one million charging cycles.

System made of carbon and salt water

A particularly sustainable, but so far quite unexplored variant of such a hybrid supercapacitor consists of carbon and aqueous sodium iodide (NaI) electrolyte, with a positive battery electrode and a

New Value Together: Making data centres more friendly to Earth

Data explosion has inevitably been triggered by digital transformation as more services go online, especially in the post COVID-19 era. Apparently, we are fully connected  from different devices on our side while we are reading news, playing games, or streaming videos. However, the importance of data centres is often overlooked.

Data centres serve as more than just data transfer hubs or service support platforms. It is indeed a critical infrastructure for the global digital economy, raising concerning of the increasing energy consumption.

According to the 2020 figures from Data Centre Knowledge, energy consumption of data centres is expected to triple over the next decade, compared to the current level of around 1% of global energy consumption.

Energy consumption is a common concern

Greenpeace provided a similar prediction in 2019, saying that data centres in China will consume as much as 266.79 Terawatt hours (TWh) of energy by 2023, compared to
