(2+1) Resonance Enhanced Ionization Spectroscopy of a State Selected Beam of OH Radicals [PDF]

, 2005
A state-selected beam of hydroxyl radicals is generated using a pulsed discharge source and hexapole field. The OH radicals are characterized by resonance-enhanced multiphoton ionization (REMPI) spectroscopy via the nested D  and 3  Rydberg states ...

Free Radicals [PDF]

, 2010
Commissioned article looking back at London's printmaking workshops of the 1960s and 70s, DIY sites of political and community activism that rejected the role of the artist to participate in a network of campaign groups, radical publishers and ...

A Class of Periodic Continued Radicals [PDF]

, 2012
We compute the limits of a class of periodic continued radicals and we establish a connection between them and the fixed points of the Chebycheff ...

Electrochemical synthesis of peroxomonophosphate using boron-doped diamond anodes [PDF]

, 2008
A new method for the synthesis of peroxomonophosphate, based on the use of boron-doped diamond electrodes, is described. The amount of oxidant electrogenerated depends on the characteristics of the supporting media (pH and solute concentration) and on ...

Identification of Peroxiredoxin (PRX) Genes from Pepper Fruits: Involvement in Ripening and Modulation by Nitric Oxide (NO)

Antioxidants
Peroxiredoxins (Prxs; EC 1.11.1.15) are a group of thiol peroxidases that catalyze the detoxification of H2O2 and other organic hydroperoxides. The ripening of pepper (Capsicum annuum L.) fruit involves significant phenotypic, physiological, and ...

Combined Electron Magnetic Resonance and Density Functional Theory Study of Thermally Induced Free Radical Reactions in Fructose and Trehalose Single Crystals [PDF]

, 2009
Both as models for studying the effects of radiation on the DNA sugar unit and for applications in dosimetry, radiation-induced defects in sugars have in the past few decades been intensively studied with electron magnetic resonance (EMR) techniques ...

Dichloromethylation of enones by carbon nitride photocatalysis

, 2020
Small organic radicals are ubiquitous intermediates in photocatalysis and are used in organic synthesis to install functional groups and to tune electronic properties and pharmacokinetic parameters of the final molecule.

Radicals of 0-regular algebras [PDF]

, 2006
We consider a generalisation of the Kurosh--Amitsur radical theory for rings (and more generally multi-operator groups) which applies to 0-regular varieties in which all operations preserve 0.

Stressful Events Reported by Childhood Cancer Survivors and Community Controls From the St. Jude Lifetime (SJLIFE) Cohort: A Mixed Method Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.

Populations and Dynamics of Guanine Radicals in DNA strands—Direct versus Indirect Generation

Molecules, 2019
Guanine radicals, known to be involved in the damage of the genetic code and aging, are studied by nanosecond transient absorption spectroscopy. They are generated in single, double and four-stranded structures (G-quadruplexes) by one and two-photon ...
