Week 28 Research Review Analysis Week 28 produced high nominal Tc values: 302.2 K for the benchmark set, 298.0 K for La/Al-substituted Li2(Mg,Ca)BH16 and 296.3 K for the Na/Be/La variant. These numbers are undermined by a calibration problem. The benchmark

Week 27 Research Review Analysis Week 27's nominal Tc maxima cannot be accepted at face value. The Day 4 top five all sit at exactly 60.0 GPa, the lower bound of the stability window used, and the Day 5 top five are all capped at exactly 280.

Week 26 Research Review Analysis Week 26 produced a clear performance hierarchy. The Be-free analogues (Day 5, 284.1 K at 146.3 GPa) and B-substitution on the Be site (Day 3, 268.2 K at 171.9 GPa) far outperformed the parent Li2(Mg0.55Ca0.45)BeH16
Weekly-Review
Week 25 Research Review Analysis Week 25 produced a sharp methodological contrast that must dominate Week 26 planning: the only campaign with explicit anharmonic phonon validation (Day 1) yielded a modest Tc of 151.9 K at 85 GPa, whereas the harmonic-level screenings escalated to 240.3 K at

Week 24 Research Review Analysis Week 24 produced two standout outcomes: the quaternary Li₂(Mg₁₋ₓCaₓ)(Be₁₋ᵧBᵧ)H₁₆ system reached the highest Tc (432 K) but only at ~198 GPa, while the boron-free Li₂(Mg₁₋ₓCaₓ)BeH₁₆ achieved 377 K at a dramatically lower 69 GPa — by far
Weekly-Review
Week 23 Research Review Analysis Week 23 screening revealed the boron-substituted quaternary hydride Li₂(Mg₁₋ₓCaₓ)(Be₁₋ᵧBᵧ)H₁₆ as the standout system, reaching a remarkable 542.5 K but requiring high pressure (285.9 GPa), suggesting B-substitution dramatically enhances electron-phonon coupling at a steep pressure cost.
Weekly-Review
Week 22 Research Review Analysis Week 22 explored the Li-Mg-Ca-Be-B-H hydride family with promising room-temperature candidates, but the results contain both credible leads and clear artifacts. The most scientifically defensible result is Day 1's Li₂(Mg₁₋ₓCaₓ)BeH₁₆ at Tc=266.6
Weekly-Review
Week 21 Research Review Analysis Week 21 screening explored the H₁₆-cage superhydride family, producing a wide Tc range from 190 K to nominally 594.8 K. The Li₂(Mg,Ca)BeH₁₆ system (Day 4) and the (Ca,Li)₂(Be,B)H₁₆ system (Day 3) yielded the highest predicted Tc
Weekly-Review
Week 20 Research Review Analysis Week 20 results reveal a clear inverse trade-off between predicted Tc and physical plausibility across the H₁₆ superhydride family. The Day 1 (Ca,Li)₂(Be,B)H₁₆ system reports Tc values above 2000 K, which are physically implausible and almost certainly reflect numerical artifacts
Weekly-Review
Week 19 Research Review Analysis Week 19 screening identified several BeH₁₆-based clathrate hydrides with exceptional predicted Tc values, with the (Ca₁₋ₓLiₓ)₂(Be₁₋ᵧBᵧ)H₁₆ system reaching 582.5 K and Ca₂BeH₁₆ reaching 423.9 K, though both require extreme pressures (275-297 GPa). The most practically promising
Weekly-Review
Week 18 Research Review Analysis Week 18 results reveal a critical credibility problem alongside genuinely promising leads. The Day 1 and Day 2 sweeps reporting flat Tc values of exactly 420.0 K and 500.0 K across all top candidates strongly indicate saturation artifacts, hard-coded ceilings, or unphysical

Week 17 Research Review Analysis Week 17 established the Ca₂BeH₁₆ system as a robust near-room-temperature superconductor platform, with SSCHA re-validation confirming Tc≈335.6 K at 180.2 GPa and demonstrating a broad Tc plateau across 168–203 GPa that suggests favorable mechanical stability. The quaternary
