Greenhouse gas emissions are at an all-time high and Earth is warming faster than ever, says researcher
Greenhouse gas emissions are at an all-time high, with yearly emissions equivalent to 54 billion tons of carbon dioxide. Humanity has caused surface temperatures to warm by 1.14°C since the late 1800s—and this warming is increasing at an unprecede.....»»
KISS method for 2D material preparation: Unlocking new possibilities for materials science
It has almost been 20 years since the establishment of the field of two-dimensional (2D) materials with the discovery of unique properties of graphene, a single, atomically thin layer of graphite. The significance of graphene and its one-of-a-kind pr.....»»
Mac Virtual Display is limited in Vision Pro – but there’s a workaround
Apple briefly touched on using Vision Pro as a Mac Virtual Display, which could be a first step toward a true Mac-equivalent spatial computer. But it did this so briefly, and in such a low-key way, that many missed it. I’ve seen quite a few posts.....»»
Experts uncover the water and emissions footprint of snowmaking: Can we rely on it in an era of climate change?
The first-ever national study to assess the impact of developing artificial snow shows the pressure the process is putting on the climate, with the equivalent of nearly 17,000 homes' worth of annual energy needed to produce snow for yearly ski operat.....»»
New study explores phosphorus recovery from sewage sludge in China for environmental sustainability and cost analysis
In a new study published in the journal Environmental Science and Ecotechnology, researchers from Tianjin University evaluate the environmental sustainability and socio-economic costs of recovering phosphorus (P) from sewage sludge by replacing curre.....»»
Producing large, clean 2D materials made easy: Just "KISS"
Ever since the discovery of the two-dimensional form of graphite (called graphene) almost twenty years ago, interest in 2D materials and their special physical properties has skyrocketed. Famously, graphene was produced by exfoliating bulk graphite u.....»»
