Published Projected loss of brown macroalgae and seagrasses with global environmental change
(via sciencedaily.com) Original source Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.
Published New materials: Synthetic pathway for promising nitride compounds discovered
(via sciencedaily.com) Original source Chemists have successfully synthesized Ruddlesden-Popper nitrides for the first time, opening the door to new materials with unique properties.
Published Antarctic ice shelves hold twice as much meltwater as previously thought
(via sciencedaily.com) Original source Slush -- water-soaked snow -- makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models. The findings could have profound implications for ice shelf stability and sea level rise.
Published Aromatic compounds: A ring made up solely of metal atoms
(via sciencedaily.com) Original source The term aromaticity is a basic, long-standing concept in chemistry that is well established for ring-shaped carbon compounds. Aromatic rings consisting solely of metal atoms were, however, heretofore unknown. A research team recently succeeded in isolating such a metal ring and describing it in full.
Published Scientists use computational modeling to guide a difficult chemical synthesis
(via sciencedaily.com) Original source Researchers have discovered a new way to drive chemical reactions that could generate a wide variety of azetidines -- four-membered nitrogen heterocycles that have desirable pharmaceutical properties.
Published Solar technology: Innovative light-harvesting system works very efficiently
(via sciencedaily.com) Original source Researchers are reporting progress on the road to more efficient utilization of solar energy: They have developed an innovative light-harvesting system.
Published Researchers address ocean paradox with 55 gallons of fluorescent dye
(via sciencedaily.com) Original source Researchers have directly measured cold, deep water upwelling via turbulent mixing along the slope of a submarine canyon in the Atlantic Ocean.
Published El Niño forecasts extended to 18 months with innovative physics-based model
(via sciencedaily.com) Original source As more attention is drawn to possible severe weather around the world scientists are looking to improve planning for possible droughts, floods and other scenarios. A team of researchers created a new tool that will allow forecasting of El Nino Southern Oscillation by up to 18 months.
Published A new study highlights potential of ultrafast laser processing for next-gen devices
(via sciencedaily.com) Original source A new study uncovers the remarkable potential of ultrafast lasers that could provide innovative solutions in 2D materials processing for many technology developers such as high-speed photodetectors, flexible electronics, biohybrids, and next-generation solar cells.
Published An optical lens that senses gas
(via sciencedaily.com) Original source A research team has developed a small optical lens, only a few millimeters in size, whose refractive behavior changes in the presence of gas. This 'intelligent' behavior of the micro-lens is enabled by the hybrid glass material from which it is made. The molecular structure of the lens consists of a three-dimensional lattice with cavities that can accommodate gas molecules, thereby affecting the optical properties of the material.
Published Towards non-toxic antifouling agents: A novel method for total synthesis of scabrolide F
(via sciencedaily.com) Original source Norcembranolide diterpenes, isolated from the soft corals of the genus Sinularia, are important compounds for the development of new drugs, owing to their diverse biological activities. However, total synthesis methods for these compounds are scarce. Now, a team of researchers has achieved the total synthesis of scabrolide F, a norcembranolide diterpene. They also revealed its non-toxic antifouling properties. This novel method can lead to the development of new drugs and antifouling agents.
Published Underwater mountains have a big impact on ocean circulation
(via sciencedaily.com) Original source Colossal undersea mountains, towering up to thousands of metres high, stir up deep sea currents: impacting how our ocean stores heat and carbon. An international team used numerical modelling to quantify how underwater turbulence around these mountains, called seamounts, influences ocean circulation; finding it is an important mechanism in ocean mixing and one that is missing from climate models used in policymaking.
Published Researchers discover new flat electronic bands, paving way for advanced quantum materials
(via sciencedaily.com) Original source Scientists predict the existence of flat electronic bands at the Fermi level, a finding that could enable new forms of quantum computing and electronic devices.
Published Novel application of optical tweezers: Colorfully showing molecular energy transfer
(via sciencedaily.com) Original source Using a novel non-contact approach, a research team has successfully controlled the speed and efficiency of Forster resonance energy transfer between fluorescent molecules by varying the intensity of a laser beam.
Published Novel catalysts for improved methanol production using carbon dioxide dehydrogenation
(via sciencedaily.com) Original source Encapsulating copper nanoparticles within hydrophobic porous silicate crystals has been shown to significantly enhance the catalytic activity of copper-zinc oxide catalysts used in methanol synthesis via CO2 hydrogenation. The innovative encapsulation structure effectively inhibits the thermal aggregation of copper particles, leading to enhanced hydrogenation activity and increased methanol production. This breakthrough paves the way for more efficient methanol synthesis from CO2.
Published Much of the Nord Stream gas remained in the sea
(via sciencedaily.com) Original source Much of the methane released into the southern Baltic Sea from the Nord Stream gas pipeline has remained in the water. This is shown by measurements taken by researchers from the University of Gothenburg.
Published Researchers create new class of materials called 'glassy gels'
(via sciencedaily.com) Original source Researchers have created a new class of materials called 'glassy gels' that are very hard and difficult to break despite containing more than 50% liquid. Coupled with the fact that glassy gels are simple to produce, the material holds promise for a variety of applications.
Published Restored rat-free islands could support hundreds of thousands more breeding seabirds
(via sciencedaily.com) Original source Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.
Published Custom-made molecules designed to be invisible while absorbing near-infrared light
(via sciencedaily.com) Original source Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light.
