Recent heavy-ion collision experiments reported a surprisingly short lifetime for the hypertriton, which has been recognized as the hypertriton lifetime puzzle. Our J-PARC E73 experiment contributes to solve this puzzle with an independent experimental method by employing 3He(K−, π0) 3ΛH reaction. In this contribution, we will demonstrate our capability to provide 3ΛH binding energy information by deriving the production cross section ratio, σ3ΛH/σ4ΛH. The production cross section data for 3ΛH and 4ΛH are already available as the pilot run of E73 experiment and data analysis is in progress.

Reasonable design of a kind of non-noble metal catalyst with high catalytic performance, good stability and low cost is of great significance to realize the overall water splitting. Herein, a bottom-up method is proposed to synthesize NiFe layered double hydroxides (NiFe LDHs) coated sulfide/phosphide heterostructure on the nickel foam (Ni3S2-NixPy/NF@NiFe LDH) through hydrothermal method combined with electrodeposition. Low overpotentials of only 248 and 298 mV are required to achieve the current densities of 50 and 100 mA cm−2 for OER. Meanwhile, the HER performance only needs 137 mV at a current density of 10 mA cm−2. [ABSTRACT FROM AUTHOR]

Capsicum annuum is one of the oldest domesticated crops in the Americas, which is also the most widely grown spice crop in the world. The complete chloroplast genome of C. annuum has been assembled and annotated in this paper. Its length was 156,781 bp, containing a large single-copy region of 87,367 bp, a small single-copy region of 17,850 bp, and a pair of IR regions of 25,782 bp in each. The whole chloroplast genome of C. annuum contains 135 genes, including 89 protein-coding genes (PCGs), 38 transfer RNA genes (tRNAs), and 8 ribosome RNA genes (rRNAs). The overall nucleotide composition is: A of 30.8%, T of 31.5%, C of 19.1% and G of 18.6%, with a total GC content of the chloroplast genome 37.7% and AT of 62.3%. Phylogenetic relationship analysis was based on 10 plant species using the maximum-likelihood (ML) methods, which showed that the position of C. annuum clustered with C. galapagoense.
