A review on the influence of drinking water quality towards human health [PDF]
, 2020 An adequate supply of safe drinking water is one of the major prerequisites for a healthy life. Inadequate of safe drinking water produce waterborne disease and a major cause of death in many parts of the world, particularly in children.

A General Strategy for the Synthesis of Jerangolids Enabled by π‐allyl Stille Coupling
Chemistry – A European Journal, EarlyView.A general strategy for the synthesis of jerangolids is established, featuring a late‐stage π‐allyl Stille coupling of two advanced, highly customizable building blocks to form the skipped diene core. The approach provides access to all naturally occurring jerangolids, including jerangolid H, whose configuration is confirmed by NMR analysis.

Chemistry – A European Journal, EarlyView.Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Hammett Correlations in the \u3csup\u3e1\u3c/sup\u3eH NMR Spectra of Some N-Arlydihalonicotinamides [PDF]
, 1992 Excellent linear correlations of amide proton chemical shifts (Snh) (in DMSO-d6 ) with Hammett substituent constants (5) for a series of 4-substituted anilides of four dihalonicotinic acid systems were observed. Dihalonicotinanilides with chlorine in the

An implicit scheme for solving the anisotropic diffusion of heat and cosmic rays in the RAMSES code
, 2015 Astrophysical plasmas are subject to a tight connection between magnetic fields and the diffusion of particles, which leads to an anisotropic transport of energy.

Photolytic Hydrophosphination: Insights Into Catalyzed and Uncatalyzed Processes
Chemistry – A European Journal, EarlyView.Catalyst‐free photolytic hydrophosphination is demonstrated for vinyl arenes and activated alkenes in polar protic (alcohol) solvents. These reactions appear to be closed‐shell, affirming that even ambient light can impact a reaction—a potentially broad influence on even mundane reactions.

Finite Larmor Radius Effects on Weakly Magnetized, Dilute Plasmas [PDF]
, 2010 We investigate the stability properties of a hot, dilute and differentially rotating weakly magnetized plasma which is believed to be found in the interstellar medium of galaxies and protogalaxies and in the low-density accretion flows around some giant ...

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes

An iterative semi-implicit scheme with robust damping
, 2008 An efficient, iterative semi-implicit (SI) numerical method for the time integration of stiff wave systems is presented. Physics-based assumptions are used to derive a convergent iterative formulation of the SI scheme which enables the monitoring and ...
