LK-99 Disappoints as Room-Temperature Superconductor.

– LK-99 (modified lead-apatite): claimed revolutionary room-temperature superconductor.

– Labs worldwide attempt recreation, but skepticism grows due to lack of evidence.

– Reproduction of material leads to disappointing results in newly published studies.

– Hoped-for superconductivity missing; resistance observed as temperature drops.

– Initial excitement wanes; doubts arise about the validity of the original claim.

– Critical temperature not reached, contrary to expectations.

– Material's resistivity increases with lowering temperature, acting opposite to superconductors.

– The dream of ambient pressure superconductor fades as evidence contradicts initial claims.
