Quantum Black Hole Force Cosmic Expansion
This work presents the Quantum Black Holes Force Cosmic Expansion (QBHFCE) theory, which resolves the cosmological constant problem through quantum black hole dynamics. The framework introduces 50+ equations with falsifiable predictions, including: - High-redshift galaxy excess (N=1.8×ΛCDM at z>10) observable by JWST - TeV-scale quantum black hole ...

On the Preparation of Nickel Porphyrins Bearing Two to Four Nitro Groups at β‐Positions
European Journal of Organic Chemistry, EarlyView.The preparation and unambiguous identification via NMR spectroscopy of all six β$\beta$,β‐dinitrometalloporphyrin isomers and three out of fourβ$\beta$,β,β‐trinitrometalloporphyrin isomers are described, along with attempts to prepare β,β,β,β‐tetranitrometalloporphyrins via both direct nitration and condensation of nitropyrroles.

Synthesis of Rare‐Bacterial Sugar Analogs: Thomosamine and Fluorinated Thomosamine
European Journal of Organic Chemistry, EarlyView.We present the synthesis of protected thomosamine (4‐amino‐4,6‐dideoxy‐d‐galactopyranose), 3‐deoxy‐3‐fluoro‐thomosamine, and 2,3‐dideoxy‐2,3‐difluoro‐thomosamine from levoglucosan (1,6‐anhydro‐β‐d‐glucopyranose). Bacterial carbohydrates that include unusual deoxy amino sugars represent interesting targets in drug discovery.

Food Frontiers, EarlyView.Two water‐soluble polysaccharides were isolated and purified from Tricholoma flavovirens (TF‐P) and Trametes versicolor (TV‐P), respectively. The structures of the two polysaccharides were identified by combining GPC, FT‐IR, HPLC, GC–MS, and NMR, and the structure–activity relationship has also been studied using immune cells and tumor cells. TV‐P with
