A study by Tohoku University found that depressive symptoms are higher in coastal areas than inland areas affected by the Great East Japan Earthquake. Four percent of participants experienced considerable posttraumatic stress reaction (PTSR). Psychologists have provided support to over 600 residents with psychological problems.
A new study by Tohoku University researchers found that meteorite impacts can create nucleobases and amino acids, essential components of life. The team's hypervelocity impact experiments revealed the formation of two types of nucleobases and nine proteinogenic amino acids.
Researchers found that massive storm systems can cause devastating tsunami-type waves, like in Typhoon Haiyan. The 'surf beat' phenomenon occurs when long wave groups approach shallow areas, breaking and transporting water onshore.
A research team has discovered a new chemical reaction pathway on titanium dioxide that allows hydrogen atoms to tunnel away from the surface. This breakthrough could lead to efficient hydrogen storage technology, addressing the challenge of storing and transporting hydrogen for renewable energy applications.
A new method of converting squalene from microalgae to gasoline or jet fuel has been developed by Tohoku University researchers. The process uses a highly dispersed ruthenium catalyst supported on cerium oxide, producing branched alkanes with high stability and low freezing points.
Researchers at Tohoku University have successfully fabricated an atomically thin, high-temperature superconductor film with a Tc of up to 60 K, exceeding that of bulk FeSe. This finding enables the control and tuning of Tc, opening up new avenues for investigating mechanism and developing next-gen nano-scale superconducting devices.
The researchers developed a novel ultra-compact heterogeneous wavelength tunable laser diode using silicon photonics and quantum-dot technology, achieving a wide-range tuning operation of around 1250 nm wavelength with an ultra-small device footprint. The obtained frequency tuning-range of 8.8 THz is a world record for QD and silicon p...
The study found that axial momentum loss occurs in the helicon plasma thruster due to internal electric fields. This loss significantly affects propulsive performance. The findings suggest more detailed understanding of plasma dynamics is needed for further development of high-power, electrodeless propulsion devices.
A research team led by Tohoku University has discovered a new family of molecular superconductors that achieve the highest known critical temperature. The discovery, published in Science Advances, reveals a new state of matter - the Jahn-Teller metal - where balancing molecular and itinerant character leads to maximum Tc.
