Chemotaxonomy and Bioactivity of Cupressus sempervirens Varieties Essential Oils: Insights Into Their Antioxidant and Enzyme Inhibitory Potential

open access: yesChemistry &Biodiversity, EarlyView.
This figure summarizes the study on the chemotaxonomy and biological activities of essential oils from three Tunisian Cupressus sempervirens varieties (var. horizontalis, var. numidica, and var. pyramidalis). Essential oils were obtained by hydrodistillation and analyzed by GCMS, revealing 47 identified compounds, with α‐pinene and 3‐carene as the ...

The effect of microstructure and strength on the fracture toughness of an 18 Ni, 300 grade maraging steel [PDF]

open access: yes
Fractography and metallographic sectioning were used to investigate the influence of microstructure and strength on the fracture toughness (KIc) and fracture mechanism of an 18 Ni, 300 grade maraging steel. Increased yield strength from 1442 to 2070 MN/m

The Secrets of Notakto: Winning at X-only Tic-Tac-Toe [PDF]

open access: yes, 2013
We analyze misere play of impartial tic-tac-toe---a game suggested by Bob Koca in which both players make X's on the board, and the first player to complete three-in-a-row loses. This game was recently discussed on mathoverflow.net in a thread created by

Strategic Insights From Playing the Quantum Tic-Tac-Toe

open access: yes, 2010
In this paper, we perform a minimalistic quantization of the classical game of tic-tac-toe, by allowing superpositions of classical moves. In order for the quantum game to reduce properly to the classical game, we require legal quantum moves to be ...

Eperua oleifera Ducke (Fabaceae) Oilresin Chemical Composition and the Isolation of a Natural Diterpenic Acid Methyl Ester

open access: yesChemistry &Biodiversity, EarlyView.
Eperua oleifera (Fabaceae) oilresin presents not only diterpenic acids, but also diterpenic acid methyl ester. ABSTRACT Eperua oleifera Ducke, commonly known as “copaíba‐jacaré,” produces oilresins traditionally used in folk medicine for wound healing and as antifungal and antibacterial agents, similar to those of Copaifera species.

Development of Granzyme A Turn‐ON Fluorescent Activity‐Based Probes

open access: yesChemBioChem, EarlyView.
A quenched activity‐based probe, featuring the Ile–Gly–Asn–Arg recognition sequence, a phenyl phosphinate ester warhead, and a near‐infrared sulfo‐Cy5/QSY21 fluorophore/quencher pair, generates a fluorescence signal only upon reaction with active granzyme A (GzmA). With its high reactivity, selectivity, and cell permeability, this turn‐ON probe enables
