Published Controlling electric double layer dynamics for next generation all-solid-state batteries
(via sciencedaily.com) Development of all-solid-state batteries is crucial to achieve carbon neutrality. However, their high surface resistance causes these batteries to have low output, limiting their applications. To this end, researchers have employed a novel technique to investigate and modulate electric double layer dynamics at the solid/solid electrolyte interface. The researchers demonstrate unprecedented control of response speed by over two orders of magnitude, a major steppingstone towards realization of commercial all-solid-state batteries.
Published Extreme fast charging capability in lithium-ion batteries
(via sciencedaily.com) Lithium-ion batteries dominate among energy storage devices and are the battery of choice for the electric vehicle industry. Improving battery performance is a constant impetus to current research in this field. Towards this end, a group of researchers has synthesized a lithium borate-type aqueous polyelectrolyte binder for graphite anodes. Their new binder helped improve Li-ion diffusion and lower impedance compared to conventional batteries.
Published Deforestation in the tropics linked to a reduction in rainfall
(via sciencedaily.com) Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.
Published Flower power: The role of ants in forest regeneration
(via sciencedaily.com) Ants play a key role in forest regeneration, according to a new article.
Published Australia's rarest bird of prey disappearing at alarming rate
(via sciencedaily.com) Australia's rarest bird of prey -- the red goshawk -- is facing extinction, with Cape York Peninsula now the only place in Queensland known to support breeding populations.
Published The rediscovery of an ethereal fairy lantern brightly illuminates their mysterious past
(via sciencedaily.com) After more than 30 years, botanists have rediscovered Thismia kobensis, a type of mysterious-looking rare plant commonly referred to as 'fairy lanterns'. Thismia kobensis was presumed extinct and the surprise rediscovery of this Japanese variety has illuminated hidden aspects of fairy lanterns that have puzzled and fascinated botanists for centuries.
Published Corralling ions improves viability of next generation solar cells
(via sciencedaily.com) Researchers have discovered that channeling ions into defined pathways in perovskite materials improves the stability and operational performance of perovskite solar cells. The finding paves the way for a new generation of lighter, more flexible, and more efficient solar cell technologies suitable for practical use.
Published New method creates material that could create the next generation of solar cells
(via sciencedaily.com) Perovskites, a family of materials with unique electric properties, show promise for use in a variety fields, including next-generation solar cells. A team of scientists has now created a new process to fabricate large perovskite devices that is more cost- and time-effective than previously possible and that they said may accelerate future materials discovery.
Published Marine heatwaves decimate sea urchins, molluscs and more at Rottnest
(via sciencedaily.com) Researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.
Published A new chip for decoding data transmissions demonstrates record-breaking energy efficiency
(via sciencedaily.com) A new chip called ORBGRAND can decode any code applied to data transmitted over the internet with maximum accuracy and between 10 and 100 times more energy efficiency than other methods.
Published Effort to help pollinators shows successes, limitations
(via sciencedaily.com) A three-year effort to conserve bee populations by introducing pollinator habitat in North Carolina agricultural areas showed some positive effects, as bee abundance and diversity increased in the studied areas. But results of a study examining the program's effectiveness also showed that the quality of the habitat played a key role in these positive effects, and that habitat quality could be impacted by the way the areas are maintained over time.
Published Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state
(via sciencedaily.com) Original source Researchers have tested models of edge conduction with a device built on top of the semiconductor heterostructure which consists of gold gates that come close together. Voltage is applied on the gates to direct the edge states through the middle of the point contact, where they are close enough that quantum tunneling can occur between the edge states on opposite sides the sample. Changes in the electrical current flowing through the device are used to test the theorists' predictions.
Published Urban ponds require attention to ensure biodiversity
(via sciencedaily.com) New research suggests aquatic plants can be utilized as a tool to enhance the co-existence between aquatic invertebrates and their fish predators in urban ponds.
Published Fungi that causes pine ghost canker detected in southern California trees
(via sciencedaily.com) Original source Fungal pathogens that cause pine ghost canker are infecting conifer trees in urban forests of Southern California, scientists found.
Published New design for lithium-air battery could offer much longer driving range compared with the lithium-ion battery
(via sciencedaily.com) Scientists have built and tested for a thousand cycles a lithium-air battery design that could one day be powering cars, domestic airplanes, long-haul trucks and more. Its energy storage capacity greatly surpasses that possible with lithium-ion batteries.
Published Sea stars able to consume kelp-eating urchins fast enough to protect kelp forests, research shows
(via sciencedaily.com) Researchers have provided the first experimental evidence that a species of endangered sea star protects kelp forests along North America's Pacific Coast by preying on substantial numbers of kelp-eating urchins.
Published Ramping up domestic graphite production could aid the green energy transition
(via sciencedaily.com) Given the growing importance of graphite in energy storage technologies, a team of esearchers has conducted a study exploring ways to reduce reliance on imports of the in high-demand mineral, which powers everything from electric vehicles (EVs) to cell phones.
Published First transient electronic bandage speeds healing by 30%
(via sciencedaily.com) Researchers have developed a small, flexible, stretchable bandage that accelerates healing by delivering electrotherapy directly to the wound site. The bandage also actively monitors the healing process and then harmlessly dissolves -- electrodes and all -- into the body after it is no longer needed.
Published New technology turns smartphones into RFID readers, saving costs and reducing waste
(via sciencedaily.com) Imagine you can open your fridge, open an app on your phone and immediately know which items are expiring within a few days. This is one of the applications that a new technology would enable.
