A research team led by Dr. Huang Qing from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a new method using low-frequency Raman spectroscopy to detect ...

This property also endows the surface with pinning-free evaporation, which in turn has been exploited for analyte concentration enrichment for Surface Enhanced Raman Spectroscopic applications and ...

The best tilt-shift lenses enable you to tilt the angle of the optical path, relative to the image sensor. They also allow you to shift the optical axis so that it’s off-centre but still parallel to ...

That’s a big shift from eight years ago, when hundreds of thousands of demonstrators gathered in Washington, and Americans flocked to airports at midnight to try to thwart Trump’s travel ban.

Perhaps Mr Trump’s newfound right-hand man, Elon Musk, summarised Snoop’s radical political U-turn best, writing on X: “The vibe shift is real.” Snoop Dogg has raised eyebrows for ...

Khosrowshahi’s itinerary symbolizes a stark shift in corporate America. While many C.E.O.s once distanced themselves from Trump, they are now embracing him. And after years of trumpeting a ...

The ‘Washington Post’ reportedly has a new mission statement, and it’s just one example of a broader shift compared to Trump’s first time around. Democracy no longer dies in darkness ...

Abstract: An efficient inscription method for low insertion loss fiber Bragg gratings in ZBLAN fiber is presented, and the effects of femtosecond laser with different pulse numbers and repetition rate ...

An optical spectroscopic technique, surface-enhanced Raman spectroscopy (SERS), mostly used in the research setting for liquid sample analysis, has recently been applied to breath-based diagnostics.

NATO Secretary General Mark Rutte has called for an urgent "shift to a wartime mindset," warning that the alliance's members are not prepared enough for an increasing security threat posed by Russia.
