Published Long in the Bluetooth: Scientists develop a more efficient way to transmit data between our devices
(via sciencedaily.com)
Original source 
Researchers have developed a more energy efficient way of connecting our personal devices. New technology consumes less power than Bluetooth and can improve battery life of tech accessories, including earbuds and fitness trackers. Future applications could see us unlocking a door by touching its handle or shaking hands to exchange phone numbers.
Published Pushing the boundaries of eco-friendly chemical production
(via sciencedaily.com)
Original source 
A team of pioneering researchers has made a significant leap forward in the complex world of molecular chemistry. Their focus? Azaarenes, unique molecular puzzle pieces crucial to many everyday products, from eco-friendly agrochemicals to essential medicines. The team developed an innovative way to modify these molecules using light-powered enzymes -- a groundbreaking discovery that holds promise for new industrially relevant chemical reactions and sustainable energy solutions.
Published Hydrogen fuel can be a competitive alternative to gasoline and diesel today
(via sciencedaily.com)
Original source 
Energy researchers posit hydrogen fuel can potentially be a cost-competitive and environmentally friendly alternative to gasoline and diesel, and that supplying hydrogen for transportation in the greater Houston area can be profitable today.
Published Reforms needed to expand prescribed burns
(via sciencedaily.com)
Original source 
A new paper pinpoints obstacles and suggests strategies for getting more prescribed fire on the ground in the wildfire-prone U.S. West.
Published No one-size-fits-all solution for the net-zero grid
(via sciencedaily.com)
Original source 
As power generation from sources like solar and wind increases, along with the introduction of devices such as heat pumps and batteries, a new optimization tool will help the UK plan for a greener electricity network. The researchers developed an algorithm to model how these smaller networks distributed electricity -- factoring in how local grids could become unbalanced by adding too many heat pumps in a single area or generating more electricity than the grid could accept.
Published Nuclear expansion failure shows simulations require change
(via sciencedaily.com)
Original source 
A team of researchers looked back at a model that predicted nuclear power would expand dramatically in order to assess the efficacy of energy policies implemented today.
Published Water splitting reaction for green hydrogen gas production improved
(via sciencedaily.com)
Original source 
Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have now designed an electrode with Schottky Junction formed at the interface of metallic Ni-W5N4 and semiconducting NiFeOOH. The proposed electrode shows excellent catalytic activity and can facilitate industrial seawater splitting continuously for 10 days.
Published Using cosmetic ingredient for battery protection
(via sciencedaily.com)
Original source 
A research team has devised a battery electrode protective film using biopolymers sourced from cosmetic ingredients.
Published New water treatment method can generate green energy
(via sciencedaily.com)
Original source 
Researchers have designed micromotors that move around on their own to purify wastewater. The process creates ammonia, which can serve as a green energy source. Now, an AI method will be used to tune the motors to achieve the best possible results.
Published Putting sound waves to work to create safer public spaces
(via sciencedaily.com)
Original source 
Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors built a system of piezoelectric sensors that can be installed in walls, floors, and ceilings to absorb sound waves and collect their energy. They used computer simulations to fine-tune variables including the voltage needed to power the main device component, the frequency and intensity of the input sound, and piezoelectric sensors tested in parallel and serial configurations.
Published 'Cooling glass' blasts building heat into space
(via sciencedaily.com)
Original source 
Researchers aiming to combat rising global temperatures have developed a new 'cooling glass' that can turn down the heat indoors without electricity by drawing on the cold depths of space. The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5 degrees Celsius at noon, and has the potential to reduce a mid-rise apartment building's yearly carbon emissions by 10 percent.
Published Ammonia for fertilizers without the giant carbon footprint
(via sciencedaily.com)
Original source 
Green ammonia has the potential to drastically reduce the carbon footprint needed to produce fertilizer vital for crop-growing.
Published Wildfire, drought cause $11.2 billion in damage to private timberland in three Pacific states, study finds
(via sciencedaily.com)
Original source 
Wildfires and drought have led to $11.2 billion in damages to privately held timberland in California, Oregon and Washington over the past two decades, a new Oregon State University study found.
Published Low-intensity fires reduce wildfire risk by 60%
(via sciencedaily.com)
Original source 
High-intensity, often catastrophic, wildfires have become increasingly frequent across the Western U.S. Researchers quantified the value of managed low-intensity burning to dramatically reduce the risk of such fires for years at a time.
Published 'Indoor solar' to power the Internet of Things
(via sciencedaily.com)
Original source 
From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled electrical cords or batteries that need to be replaced. Now, researchers have brought solar panel technology indoors to power smart devices. They show which photovoltaic (PV) systems work best under cool white LEDs, a common type of indoor lighting.
Published Advances in lithium-metal batteries, paving the way for safer, more powerful devices
(via sciencedaily.com)
Original source 
The boom in phones, laptops and other personal devices over the last few decades has been made possible by the lithium-ion (Li-ion) battery, but as climate change demands more powerful batteries for electric vehicles and grid-scale renewable storage, lithium-ion technology might not be enough. Lithium-metal batteries (LMBs) have theoretical capacities an order of magnitude greater than lithium-ion, but a more literal boom has stymied research for decades.
Published Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage
(via sciencedaily.com)
Original source 
Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
