Oxidative Generation and Reactivity of the Cyclopropyl Radical From a Martin Silicate

open access: yesChemistry – A European Journal, EarlyView.
A photoredox strategy employing Martin silicates enables the oxidative generation and controlled capture of cyclopropyl radicals, including the naked one, long considered challenging intermediates. The method affords functionalized cyclopropanes through both Giese‐type additions and dual nickel/photoredox C(sp3)−C(sp2) cross‐couplings.

Common Techniques in Graceful Tree Labeling with a New Computational Approach [PDF]

open access: yes, 2016
The graceful tree conjecture was first introduced over 50 years ago, and to this day it remains largely unresolved. Ideas for how to label arbitrary trees have been sparse, and so most work in this area focuses on demonstrating that particular classes of

A New Spin on Photocatalysis: Vortex Fluidic‐Driven Photooxidations Enabled by Solution‐Processable Microporous Polymers

open access: yesChemistry – A European Journal, EarlyView.
Newly developed polymers with intrinsic microporosity (PIMs) were combined with benzo[c][1,2,5]thiadiazole (BTZ) to be used as visible light photocatalytic coatings on the Vortex Fluidic Device (VFD). The VFD's rapid rotation and continuous flow capabilities enhanced singlet oxygen and superoxide radical reactions, achieving a dramatic eightfold ...

Halogenated Tryptophans Improve Integrin αVβ6 Affinity of Cyclic RGD Peptides and Provide Handles for Late‐Stage Derivatization

open access: yesChemistry – A European Journal, EarlyView.
Lighting up αVβ6: Halotryptophan engineering converts an RGD scaffold into a modular αVβ6 ligand platform, enabling picomolar affinity and late‐stage functionalization. The resulting probes combine high selectivity with fluorescence for FACS and tumor imaging.

Modulation of Epigenetic Control by Advanced Molecular Tweezers

open access: yesChemistry – A European Journal, EarlyView.
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans

open access: yesCytoskeleton, EarlyView.
ABSTRACT Long‐distance intracellular transport of ionotropic glutamate receptors (iGluRs) is essential for proper excitatory synaptic function underlying learning and memory. Many neuropsychiatric and neurodegenerative conditions have abnormal iGluR transport and trafficking, leading to an intense interest in the mechanisms and factors regulating these

Graceful labelings of the generalized Petersen graphs

open access: yesCommunications in Combinatorics and Optimization, 2017
A graceful labeling of a graph $G=(V,E)$ with $m$ edges is an‎ ‎injection $f‎: ‎V(G) \rightarrow \{0,1,\ldots,m\}$ such that the resulting edge labels‎ ‎obtained by $|f(u)-f(v)|$ on every edge $uv$ are pairwise distinct‎.

Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

Edge Odd Graceful Labeling of Some Ladder and Path Related Graphs

open access: yes
An edge odd graceful labeling of graph G with p vertices and q edges is a modular technique of edge labeling, introduced bySolairaju and Chithra in 2008 [9]. It is a bijection f from the edge set E(G) of the graph to {1, 3,…, 2q - 1} such that, when each
