  2. PCB congener list - Wikipedia

    en.wikipedia.org/wiki/PCB_congener_list

    Congener descriptors give a shorthand notation for geometry and substituent positions. The twelve congeners that display all four of the descriptors are referred to as being "dioxin-like", referring both to their toxicity and structural features which make them similar to 2,3,7,8-tetrachlorodibenzo-p-dioxin (2378-TCDD).

  3. Polychlorinated biphenyl - Wikipedia

    en.wikipedia.org/wiki/Polychlorinated_biphenyl

    The coplanar group members have a fairly rigid structure, with their two phenyl rings in the same plane. It renders their structure similar to polychlorinated dibenzo- p -dioxins (PCDDs) and polychlorinated dibenzofurans , and allows them to act like PCDDs, as an agonist of the aryl hydrocarbon receptor (AhR) in organisms.

  4. Coplanar waveguide - Wikipedia

    en.wikipedia.org/wiki/Coplanar_waveguide

    Coplanar waveguides play an important role in the field of solid state quantum computing, e.g. for the coupling of microwave photons to a superconducting qubit.In particular the research field of circuit quantum electrodynamics was initiated with coplanar waveguide resonators as crucial elements that allow for high field strength and thus strong coupling to a superconducting qubit by confining ...

  5. Coplanarity - Wikipedia

    en.wikipedia.org/wiki/Coplanarity

    In geometry, a set of points in space are coplanar if there exists a geometric plane that contains them all. For example, three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. However, a set of four or more distinct points will, in general, not lie in a single plane.

    A Serie A match between ACF Fiorentina and Inter Milan was abandoned after a player collapsed on the field on Sunday at the Stadio Artemio Franchi in Florence, Italy.

  7. Via fence - Wikipedia

    en.wikipedia.org/wiki/Via_fence

    Via fences use up a lot of valuable substrate real estate and so will increase the overall size of the assembly. Via fences too close to the line being guarded can degrade the isolation otherwise achievable. In stripline, a rule of thumb is to place the fences at least four times the trace to groundplane distance away from the line being ...
