Seiichi Shirai (1905-1983) was an influential architect whose work has affected the designs of significant architects of the 20th century. Associate Professor Kosuke Hato of the Department of Architecture, Faculty of Engineering, Shinshu University has studied the work of Shirai and examined why the architect worked extensively on calligraphy. Hato's strategy is to clarify the relationship between the architect and his activity of calligraphy through Shirai's Theory of Tradition.
Is it possible to drive nanoparticles to orbit below the light diffraction limit using a Gaussian beam? A recent joint research project reported in Nature Communications says yes.
The energy density of traditional lithium-ion batteries is approaching a saturation point that cannot meet the demands of the future - for example in electric vehicles. Lithium metal batteries can provide double the energy per unit weight when compared to lithium-ion batteries. The biggest challenge, hindering its application, is the formation of lithium dendrites, small, needle-like structures, similar to stalagmites in a dripstone cave, over the lithium metal anode.
Nitrogen from agriculture, vehicle emissions and industry is endangering butterflies in Switzerland. The element is deposited in the soil via the air and has an impact on vegetation - to the detriment of the butterflies, as researchers at the University of Basel have discovered.
The 2018 Nobel Prize in Physics was shared by researchers who pioneered a technique to create ultrashort, yet extremely high-energy laser pulses at the University of Rochester.
Now researchers at the University's Institute of Optics have produced those same high-powered pulses--known as chirped pulses--in a way that works even with relatively low-quality, inexpensive equipment. The new work could pave the way for:
Better high-capacity telecommunication systems
Improved astrophysical calibrations used to find exoplanets
Even more accurate atomic clocks
Modelling the financial system as a network is a precondition to understanding and managing challenges of great relevance for society, including the containment of financial crises and the transition to a low-carbon economy.
Researchers from Tokyo Medical and Dental University (TMDU) find that the secretion of uromodulin protein into urine can be induced by treatments that may protect against urinary tract infections and kidney stones, among other diseases
Chemical engineers at the University of Illinois Chicago and UCLA have answered longstanding questions about the underlying processes that determine the life cycle of liquid foams. The breakthrough could help improve the commercial production and application of foams in a broad range of industries.
Findings of the research were featured this month in Proceedings of the National Academy of Sciences.
The glaciers of Nanga Parbat - one of the highest mountains in the world - have been shrinking slightly but continually since the 1930s. This loss in surface area is evidenced by a long-term study conducted by researchers from the South Asia Institute of Heidelberg University. The geographers combined historical photographs, surveys, and topographical maps with current data, which allowed them to show glacial changes for this massif in the north-western Himalaya as far back as the mid-1800s.
A long-term passive rewilding study has shown that natural regeneration could make a significant contribution to meeting the UK's ambitious woodland expansion targets - potentially at no cost and within relatively short timescales.
The research, led by the UK Centre for Ecology & Hydrology (UKCEH), found natural growth due to seed dispersal by birds, mammals and wind can produce biodiverse and resilient woodland.
Woodland development can be rapid, while avoiding the cost, management and plastic tubing involved in planting schemes.
Physicists at Ludwig-Maximilian University in Munich (LMU) and the Max Planck Institute for Quantum Optics (MPQ) have used ultrashort laser pulses to probe the dynamics of photoelectron emission in tungsten crystals.
Light-driven molecular motors have been around for over twenty years. These motors typically take microseconds to nanoseconds for one revolution. Thomas Jansen, associate professor of physics at the University of Groningen, and Master's student Atreya Majumdar have now designed an even faster molecular motor. The new design is driven by light only and can make a full turn in picoseconds, using the power of a single photon.
As pandemic restrictions begin to loosen around the country and summer temperatures rise, more people will be moving about on public rideshare electric scooters. With that comes this warning: Ride with safety.
A Henry Ford Health System study published in The Laryngoscope, shows that head and neck injuries caused by use of e-scooters have been on the rise since rideshare systems were introduced to the public in late 2017.
LOS ALAMOS, N.M., June 17, 2021 -- A research team from Los Alamos National Laboratory and Purdue University have developed bio-inks for biosensors that could help localize critical regions in tissues and organs during surgical operations.
"The ink used in the biosensors is biocompatible and provides a user-friendly design with excellent workable time frames of more than one day," said Kwan-Soo Lee, of Los Alamos' Chemical Diagnostics and Engineering group.
The new biosensors allow for simultaneous recording and imaging of tissues and organs during surgical procedures.
