Direct Observation of Intermediates Involved in the Interruption of the Bischler–Napieralski Reaction by White, Kolby L., Mewald, Marius, Movassaghi, Mohammad

“…The reversible formation of diiminium ether intermediates was studied, providing insight into divergent mechanistic pathways as a function of the steric environment of the amide substrate and stoichiometry of reagents. Importantly, when considering base additives during electrophilic amide activation, more hindered α-quaternary tertiary lactams require the use of non-nucleophilic pyridine additives in order to avoid deactivation via a competing desulfonylation reaction. …”

Enhanced transport in transistor by tuning transition-metal oxide electronic states interfaced with diamond by Yin, Zongyou, Tordjman, Moshe, Lee, Youngtack, Vardi, Alon, Kalish, Rafi, del Alamo, Jesús A

“…Regrettably, field-effect transistor operation based on this surface doping has been so far disappointing due to fundamental material obstacles such as (i) carrier scattering induced by nonhomogeneous morphology of TMO surface acceptor layer, (ii) stoichiometry changes caused by typical transistor fabrication process, and (iii) carrier transport loss due to electronic band energy misalignment. …”

Temporal gene expression and regulation in T4 phage by Levine, Mandara Alexis

“…Collectively, transcriptional and translational controls lead to precisely tuned protein synthesis rates during infection, as exemplified by the phenomenon that components of T4 protein complexes are synthesized according to their stoichiometry— a principle that has been observed in organisms during steady-state growth. …”

Synthetic incoherent feedforward circuits show adaptation to the amount of their genetic template by Bleris, Leonidas, Xie, Zhen, Glass, David, Adadey, Asa, Sontag, Eduardo, Benenson, Yaakov

“…Natural and synthetic biological networks must function reliably in the face of fluctuating stoichiometry of their molecular components. These fluctuations are caused in part by changes in relative expression efficiency and the DNA template amount of the network-coding genes. …”

Non-Gated Laser Induced Breakdown Spectroscopy Provides a Powerful Segmentation Tool on Concomitant Treatment of Characteristic and Continuum Emission by Myakalwar, Ashwin Kumar, Dingari, Narahara Chari, Dasari, Ramachandra Rao, Barman, Ishan, Gundawar, Manoj Kumar

“…While use of such a system introduces substantive continuum background in the spectral dataset, we show that appropriate treatment of the continuum and characteristic emission results in accurate discrimination of pharmaceutical formulations of similar stoichiometry. Specifically, our results suggest that near-perfect classification can be obtained by employing suitable multivariate analysis on the acquired spectra, without prior removal of the continuum background. …”
