TMH assembles first Russian hydrogen passenger train, 435-mile range, ahead of tests
The first low-floor passenger train on hydrogen fuel cells has been assembled at Demikhovo and moves to testing. It is intended for non-electrified lines on Sakhalin.
Chiba University splits 8×8 mm CVD diamond along {100} plane with 10 ps laser pulses
In a laboratory test, Chiba researchers split one 8 mm × 8 mm CVD diamond along the {100} plane after four steps of 10 ps laser pulses.
Beijing team: oxygen in β phase gives Ti-6Al-4V-0.39O alloy 1200 MPa strength and 23.5% ductility
Researchers in Beijing partitioned oxygen between α and β phases of a dual-phase titanium alloy, triggering a β → O' transformation and added plasticity.
Yale and Cornell economists' geospatial model finds steel plants and estimates output, R² above 0.8
Researchers from Yale and Cornell trained models on Chinese data and applied them to South Korea and Iran; the authors propose the method for near-real-time tracking of industrial activity.
Heliopolis flint blades point to skilled part-time knappers in Predynastic Egypt
Reanalysis of 2,869 flint artefacts from Heliopolis, kept in Turin since the 1903–1906 excavations, suggests specialised blade production for other villagers before the Egyptian state.
PUDU Robotics shows six robot lines in Amsterdam, including D7 semi-humanoid with 8-hour runtime
At its European Partner Summit on November 4, the Shenzhen-based company presented all six product lines together for the first time, along with a shared technology strategy.
Humanoid robot completes a full shift on an assembly line without an operator: what the test showed
Eight hours, two operations, one stop because of a dropped part. We publish the timeline and explain why it matters more than spectacular videos.
