Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

Geological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Integrated pretreatment and fermentation strategies for L‐lactic acid production from brewers' spent grain using native Streptococcus infantarius and Bacillus coagulans

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Brewers' spent grain (BSG) is an abundant lignocellulosic byproduct of the brewing industry with strong potential as a renewable substrate for biotechnological production of lactic acid (LA). This study evaluated integrated pretreatment, enzymatic hydrolysis, and fermentation strategies to enable efficient production of optically ...

Eriope barrinhae (Lamiaceae, Hyptidinae), a new montane species from northern Minas Gerais, Brazil

Nordic Journal of Botany, EarlyView.
In northern Minas Gerais, in the Monte Azul region, the Pico da Formosa mountain remains poorly explored botanically despite recent discoveries of new taxa. During fieldwork at the summit of this mountain, we discovered a distinctive population of Eriope that differs from all known species by a unique combination of morphological characters.

Supramolecular Surface Functionalization of Single‐Walled Carbon Nanotubes With Conjugated Graft Copolymers

Journal of Polymer Science, EarlyView.
Post‐polymerization modification of poly(tetrazine‐co‐fluorene) conjugated polymer via an inverse‐electron‐demand Diels‐Alder reaction (IEDDA) introduces hydroxyl initiators that enable surface‐initiated ring‐opening polymerization (ROP) of lactide.
