Research team enhances hydrogen evolution catalyst through stepwise deposition
In order to enhance the accessibility of hydrogen-powered vehicles and establish hydrogen as a viable energy source, it's imperative to reduce the cost of hydrogen production, thereby achieving economic feasibility. To achieve this goal, maximizing t.....»»
The Impact of Air Condition Timer On Indoor Air Quality
By controlling airflow, humidity, and pollution levels, air conditioning timers may have a major effect on IAQ. Aside from their obvious comfort-enhancing function, air conditioning systems also contribute significantly to a hygienic and pleasant ind.....»»
Study validates the simple view of reading for enhancing second and foreign language learners" experience
The simple view of reading (SVR) is a widely accepted theory that attempts to define the skills that contribute to early reading comprehension. It attributes a person's reading comprehension ability to two skills—word recognition (decoding) and lan.....»»
Researchers design efficient iridium catalyst for hydrogen generation
The energy demands of the world are ever increasing. In our quest for clean and eco-friendly energy solutions, transportable hydrogen energy offers considerable promise. In this regard, proton exchange membrane water electrolyzers (PEMWEs) that conve.....»»
Air pollution linked with global rise in antibiotic resistance
Antibiotic resistance is a growing threat to global health. In 2019, it caused more than 1.27 million deaths worldwide—and it's projected that antimicrobial resistance (which includes bacterial resistance to antibiotics) may contribute to 10 millio.....»»
Researchers visualize novel catalyst at work
A novel catalysis scheme enables chemical reactions that were previously virtually impossible. A method developed at the University of Bonn is also environmentally friendly and does not require rare and precious metals......»»
New calcium material functions as an ammonia synthesis catalyst
Researchers find calcium outshines chromium in the catalytic production of ammonia. Working together, a humble trio of calcium atoms have defied expectations to break apart one of the strongest chemical bonds known. The atoms form the key part of a c.....»»
Land-use strategies, nutrient conditions contribute to oak decline
New research led by a University of Georgia ecologist sheds light, for the first time, on how land-use disturbance and nutrient conditions play a role in the decline of oak forests. The most promising strategy to address this decline is reduced cutti.....»»
Climate protection: Land use changes cause the carbon sink to decline
Forests can bind large amounts of carbon on the land surface. In this way, they decisively contribute to reducing net greenhouse gas emissions. For some areas, however, data are still lacking. In Eastern Europe, in particular, the network of installe.....»»

Researchers look at the role of graphene in space technology
Graphene has long been put forward as a wonder material. Undeniably, it has astounding properties—stronger than steel, a better electrical conductor than copper, and lighter than almost anything else with similar properties. And while it's been par.....»»
What’s going on with the reports of a room-temperature superconductor?
Rumors are flying of confirmation, but the situation is still frustratingly vague. Enlarge / The normal structure of the material (left) and distortions that occur once copper is substituted in (right). (credit: Sinéad Griffin).....»»
Rio Pará found to contribute high trace metal concentrations to the Amazon estuary
The Amazon River is the largest river in the world. It discharges about one fifth of global freshwater runoff, resulting in a freshwater plume rich in nutrients and trace elements entering the Atlantic Ocean......»»
High-resolution scattering imaging reveals vibrational-state-specific mechanisms in paradigmatic ion-molecule reaction
Charged atomic and molecular species are ubiquitous in environments such as planetary atmospheres, interstellar medium and plasma. The collisions between charged ions and neutral molecules play vital roles in determining the chemical evolution and en.....»»
Brown widow spider study shows how invasive species prosper in favorable habitats
Lower parasitism and predation in urban habitats may contribute to the invasion success of brown widow spiders. Dr. Monica Mowery and colleagues at Ben-Gurion University of the Negev compared egg sac parasitism in the urban invasive brown widow spide.....»»
