Have you ever wondered why blue light-emitting perovskite materials aren't as efficient as they could be? The problem lies in intrinsic defects that trap charge carriers. Scientists have found a clever solution: wrap CsPb(Cl/Br)3 nanocrystals in silica. This combination, known as CsPb(Cl/Br)3 NCs@Si
Imagine you're a business leader in China. Would you believe that paying taxes on pollution could actually boost your exports? Well, that's what happened with the Environmental Protection Tax Law (EPTL) introduced in 2018. This law charged companies for the pollution they produced, and the result? A
Imagine walking through the streets of Colorado during the COVID-19 pandemic. You might have noticed that some counties were hit harder than others. Why was that? Researchers found a surprising link between the outcome of the 2020 presidential election and COVID-19 mortality rates. Let's break it d
Have you ever wondered what drives the population of disease-carrying mosquitoes, like Aedes aegypti, along the U. S. -Mexico border? This mosquito species, known for spreading viruses like dengue, Chikungunya, Zika, and yellow fever, is becoming more common in temperate regions. Our study aimed to
A strange thing happened in Alaska. Around half of the common murres, those tuxedo-looking seabirds, died between 2014 and 2016. This isn't the first time they've had trouble, but it's the worst. Scientists blamed a big heat wave in the ocean, called "the Blob, " which made their food scarce. And ev
Think about this: the things we do to stay active might not be so great for the planet. This study dives into how people choose to travel for their workouts and what gear they use. It's like asking, "Can we be fit and eco-friendly at the same time? " The researchers looked at how people see themselv
The world of online retail is booming, but so is the pile of packaging waste. A recent study took a closer look at two types of reusable packaging in Canada's apparel eCommerce market. They compared these with disposable options using something called Life Cycle Assessment (LCA). In the first scena
Changing people's habits to be more eco-friendly is a common goal for many projects. But how do you make sure these interventions work and can be compared to each other? The key lies in a well-thought-out plan. Let’s dive in! First, you need a solid experimental design. This is like the blueprint o
As the world's population gets older, the role of community environments becomes crucial for healthy aging. A recent study, using data from a Chinese health survey between 2011 and 2020, looked into how suitable communities are for seniors aged 60 and above. The study divided these communities into
As technology moves forward, traditional electronics face limits. For instance, Boltzmann's law and short-channel effects pose issues for metal-oxide-semiconductor field-effect transistors (MOSFETs). But there's a new kid on the block: nanoscale air channel transistors (NACTs), which use a vacuum-li
