A Mass Spectrometry-Machine Learning Approach for Detecting Volatile Organic Compound Emissions for Early Fire Detection.
Kingsley S, Xu Z, Jones B, Saleh J, Orlando TM. Kingsley S, et al. J Am Soc Mass Spectrom. 2023 May 3;34(5):826-835. doi: 10.1021/jasms.2c00304. Epub 2023 Apr 20. J Am Soc Mass Spectrom. 2023. PMID: 37079759 Free PMC article.
CO(2), CH(3)CHO, and C(6)H(6) were the main volatiles detected during Mylar thermal decomposition, while Teflon's thermal decomposition yielded CO(2) and a set of fluorocarbon compounds including CF(4,) C(2)F(4,) C(2)F(6), C(3)F(6,) CF(2)O, and CF(3)O. PMMA p …

Detecting Hexafluoroisopropanol Using Soft Chemical Ionization Mass Spectrometry and Analytical Applications to Exhaled Breath.
Weiss F, Chawaguta A, Tolpeit M, Volk V, Schiller A, Ruzsanyi V, Hillinger P, Lederer W, Märk TD, Mayhew CA. Weiss F, et al. J Am Soc Mass Spectrom. 2023 May 3;34(5):958-968. doi: 10.1021/jasms.3c00042. Epub 2023 Mar 30. J Am Soc Mass Spectrom. 2023. PMID: 36995741 Free PMC article.
HFIP shows no observable reaction with H(3)O(+) and NO(+), but it does react efficiently with O(2)(+) via dissociative charge transfer resulting in CHF(2)(+), CF(3)(+), C(2)HF(2)O(+), and C(2)H(2)F(3)O(+). A minor competing hydride abstraction channel results in C(3)HF(6)O …

Pre-existing humoral immunity and complement pathway contribute to immunogenicity of adeno-associated virus (AAV) vector in human blood.
Smith CJ, Ross N, Kamal A, Kim KY, Kropf E, Deschatelets P, Francois C, Quinn WJ 3rd, Singh I, Majowicz A, Mingozzi F, Kuranda K. Smith CJ, et al. Front Immunol. 2022 Sep 16;13:999021. doi: 10.3389/fimmu.2022.999021. eCollection 2022. Front Immunol. 2022. PMID: 36189251 Free PMC article.
Interestingly, both full and empty viral particles were equally potent in inducing complement activation and cytokine secretion. By using a compstatin-based C3 and C3b inhibitor, APL-9, we demonstrated that complement pathway inhibition lowered CD86 levels on APCs, AAV upt …

Controllable Single and Double Difluoromethylene Insertions into C-Cu Bonds: Copper-Mediated Tetrafluoroethylation and Hexafluoropropylation of Aryl Iodides with TMSCF2H and TMSCF2Br.
Wang X, Pan S, Luo Q, Wang Q, Ni C, Hu J. Wang X, et al. J Am Chem Soc. 2022 Jul 13;144(27):12202-12211. doi: 10.1021/jacs.2c03104. Epub 2022 Jul 5. J Am Chem Soc. 2022. PMID: 35786906
The selective difluoromethylene insertion into a C-Cu bond is a challenging task and is currently limited to either a single CF(2) insertion into CuCF(3) or double CF(2) insertions into CuC(6)F(5) (or (Z)-CF(3)CF = CFCu). ...The synthetic value of the …

Blatter Radicals as Bipolar Materials for Symmetrical Redox-Flow Batteries.
Steen JS, Nuismer JL, Eiva V, Wiglema AET, Daub N, Hjelm J, Otten E. Steen JS, et al. J Am Chem Soc. 2022 Mar 23;144(11):5051-5058. doi: 10.1021/jacs.1c13543. Epub 2022 Mar 8. J Am Chem Soc. 2022. PMID: 35258956 Free PMC article.
Cyclic voltammetry shows that these radicals also retain reversible bipolar electrochemistry in the presence of water. The redox potentials of derivatives with a C(3)-CF(3) substituent are the least affected by water, and moreover, these compounds show >90% capacity ret …

Experimental and Computational Studies on the Ruthenium-Catalyzed Dehydrative C-H Coupling of Phenols with Aldehydes for the Synthesis of 2-Alkylphenol, Benzofuran, and Xanthene Derivatives.
Pannilawithana N, Pudasaini B, Baik MH, Yi CS. Pannilawithana N, et al. J Am Chem Soc. 2021 Aug 25;143(33):13428-13440. doi: 10.1021/jacs.1c06887. Epub 2021 Aug 16. J Am Chem Soc. 2021. PMID: 34428913
The Hammett plot from the coupling reaction of 3-methoxyphenol with para-substituted benzaldehydes p-X-C(6)H(4)CHO (X = OMe, Me, H, F, Cl, CF(3)) displayed a V-shaped linear slope. Catalytically relevant Ru-H complexes were observed by NMR from a stoichiometric reaction mi …

Internuclear Ophthalmoplegia as the First Manifestation of Pediatric-Onset Multiple Sclerosis and Concurrent Lyme Disease.
Chao J, Saleem S, Tausif HN, Levasseur K, Stec LA. Chao J, et al. Am J Case Rep. 2020 Oct 7;21:e925220. doi: 10.12659/AJCR.925220. Am J Case Rep. 2020. PMID: 33027244 Free PMC article.
MRI of the spinal column also demonstrated multiple areas of increased signal intensity from the C3 to C7-T1 region. Inflammatory and autoimmune studies were negative. However, her serum IgM and IgG studies were positive for Borrelia burgdorferi with negative CSF titers. …
