Centrosymmetric Crystal Displays Surprising Chiral Optical Reactions

Centrosymmetric Crystal Displays Surprising Chiral Optical Reactions

Expectations regarding optical behavior that have been widely accepted since Louis Pasteur’s groundbreaking discoveries in 1848 have been overturned by a recent study. Researchers observed optical behaviors associated with chirality in crystalline lithium cobalt selenium oxide (Li₂Co₃(SeO₃)₄), a centrosymmetric crystal that inherently cannot exhibit chirality. “Within the inorganic crystal community, there’s been a strong belief […]

Italian Industrial Executives Jailed for PFAS Pollution

Italian Industrial Executives Jailed for PFAS Pollution

An Italian court has issued a landmark ruling, sentencing 11 executives to prison due to accusations of contaminating groundwater with per- and polyfluorinated alkyl substances (PFAS) originating from the Miteni fluorochemicals facility located in Trissino, Italy. This plant, which has been operating since the 1960s, became a center of environmental concern after probes indicated it […]

From Ta Physika to Physics – Volume XLIII

Galileo’s conflicts with the Roman Catholic Church commenced with the “Letter to Castelli” in December 1613. At a dinner in Pisa with Grand Duke Cosimo II de’ Medici, philosopher Cosimo Boscaglia opposed the heliocentric theory, referencing the Bible. Benedetto Castelli, who was present and a student of Galileo, defended the heliocentric perspective. Castelli relayed this […]
