Rapid Joule-heating synthesis of metal/carbon-based electrocatalysts for efficient carbon dioxide reduction
In comparison with conventional pyrolysis processes, the researchers developed a rapid thermal shock method to achieve a uniform dispersion of metal nanoparticles on carbon supports. This approach effectively prevented nanoparticle aggregation, ensuring the full utilization of active sites.
Noise no more: transforming sound barriers with material optimization
In a bid to combat escalating traffic noise pollution, a novel study presents a semianalytical meshless method to optimize the acoustic performance of sound barriers. The research focuses on enhancing the effectiveness of these barriers by refining their shape and material distribution.
Ammonia attracts the shipping industry, but researchers warn of its risks
Switching to ammonia as a marine fuel, with the goal of decarbonisation, can instead create entirely new problems. This is shown in a study from Chalmers University of Technology in Sweden, where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia.
The influence of media narratives on microplastics risk perception revealed
Media narratives play a critical role in shaping public awareness and risk perception of microplastics.
Killer whales’ diet more important than location for pollutant exposure, study says
Both elegant and fierce, killer whales are some of the oceans’ top predators, but even they can be exposed to environmental pollution.
Tracking down environmental toxins
Detection of per- and polyfluoroalkyl substances (PFAS) by interrupted energy transfer
Bitcoin mining has “very worrying” impacts on land and water, not only carbon, UN-led study reveals
As bitcoin and other cryptocurrencies have grown in market share, they’ve been criticized for their heavy carbon footprint: Cryptocurrency mining is an energy-intensive endeavor.
Wildfires threaten environmental gains in climate-crucial Amazon
Despite steps toward decreasing deforestation, uncontrolled wildfires are threatening environmental gains in Brazilian Amazonia, one of the world’s most critical carbon sinks and a region of high biological and cultural diversity.
What is the carbon footprint of a hospital bed?
Researchers from the University of Waterloo completed the first-ever assessment of a Canadian hospital to reveal its total environmental footprint and specific carbon emission hotspots.
The health impact of climate change is not adequately recorded: study
A Monash University-led study has proposed a solution for the urgent need to capture real-time data on the impact of climate change-related events on human health, healthcare workforces, and healthcare systems at the point of care.
Tiny plastic particles also find their way into the brain
Led by Lukas Kenner (Department of Pathology at MedUni Vienna and Department of Laboratory Animal Pathology at Vetmeduni) and Oldamur Hollóczki (Department of Physical Chemistry, University of Debrecen, Hungary) the research team was able to determine that tiny polystyrene particles could be detected in the brain just two hours after ingestion. The mechanism that enabled them to breach the blood-brain barrier was previously unknown to medical science.
Biological invasions as costly as natural disasters
By invading new environments, some alien species have caused disastrous consequences for local species and ecosystems, as well as for human activities – damage to infrastructure, crops, forest plantations, fishing yields, health and tourism. The areas affected are multiple and the damage is costly.
Lynx reintroduction in Scotland? It’s complicated
Plans to reintroduce the lynx in Scotland provoke a complex range of opinions, new research shows.
Microplastics deposited on the seafloor triple in 20 years
The total amount of microplastics deposited on the bottom of oceans has tripled in the past two decades with a progression that corresponds to the type and volume of consumption of plastic products by society.
No ‘Echo Chambers’ in Reddit Climate Debate
Climate change debates on Reddit don’t happen in polarised “echo chambers”, new research suggests.
Research discovers new bacteria that stick to plastic in the deep sea to travel around the ocean
Newcastle University scientists have found new types of plastic loving bacteria that stick to plastic in the deep sea that may enable them to ‘hitchhike’ across the ocean.
Scientists call for cap on production to end plastic pollution
Now, after the United Nations’ historic decision to adopt a global treaty to end plastic pollution earlier this year, governmental negotiations on the agreement are set to begin on May 30th.
Finding Terra Incognita
A combination of atmospheric measurements and fine-scale simulations has improved understanding of the modeling anomalies that arise when the model resolution approximates the length scale of turbulence features — an atmospheric simulation problem known as Terra Incognita.
