Formation of Carbonisocyanatidic Amide in Interstellar Ice Analogs as a Candidate Precursor to Prebiotic Pyrimidines

Abstract Understanding how pyrimidine nucleobases form in space is central to prebiotic chemistry, yet the pathways assembling these heterocycles remain unresolved. Carbonisocyanatidic amide (H2NC(O)NCO), an acyclic intermediate with heteroatom connectivity relevant to uracil and...

Dataset Construction of CO2 Flux over Shifting Sand in the Taklimakan Desert and Assessment of Carbon Sequestration Capacity

Desert ecosystems, which cover extensive global regions, play an essential yet often-overlooked role in sequestering atmospheric CO 2 at substantial yet gradual rates, primarily due to insufficient monitoring, data scarcity, and limited research attention. Current assessments of...

Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...

Detection of the elusive cyclo−1,2-dihydrotetrazete (N4H2) in the gas phase

Nitrogen hydrides (NnHm) have attracted significant interest for their potential in developing high-energy-density materials. The synthesis of cyclic nitrogen hydrides is particularly challenging due to their inherently high strain energies. Here we report the preparation of the...
