On the interference of 210Pb in the determination of 90Sr using a strontium specific resin [PDF]

Nuclear Technology and Radiation Protection, 2013
We investigated the interference of radiolead in the isolation of radiostrontium using a strontium-specific resin by means of 85Sr and 212Pb radiotracers. The resin was found to be almost equally specific for lead ions as well.

Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

Effect of Scintillation Cocktail and Quenching Calibration Method on Measurement of 55Fe by LSC

He huaxue yu fangshe huaxue
In order to optimize the measurement conditions of 55Fe by liquid scintillation counting, the effect of three kinds of commercial scintillation cocktail and two efficiency correction methods on LSC measurements of 55Fe was tested.

Covalent Peptide‐Graphene Conjugates for Enhanced Cell Spreading, Osteogenic Differentiation, and Angiogenesis in Bone Defects

ChemBioChem, EarlyView.
The three peptides RGD, DGEA, and KKGHK are covalently attached to the 2D nanomaterial graphene oxide (GO) to create new biomaterials for the treatment of severe bone injuries. These GO modifications improve cell spreading, stem cell differentiation into bone cell types, and formation of blood vessel‐like structures.

Novel 4,5‐Dihydrothiazole‐Phenylpiperazine Derivatives: Synthesis, Docking Studies and Pharmacological Evaluation as Serotonergic Agents

ChemMedChem, EarlyView.
The synthesis of a new series of 4,5‐dihydrothiazol‐2‐ylphenylpiperazine derivatives as serotoninergic ligands is described and tested for their affinity toward 5‐HT1A, 5‐HT2A,and 5‐HT2C and selected for further in vivo assays to determine their functional activity. The pharmacological studies highlight that among the developed derivatives, FG‐7 and FG‐

Compression‐Induced Amorphization of ZIF‐62 Leading to Formation of Porous Glass: Overcoming the Limitations of Current Methods

Chemistry–Methods, EarlyView.
Nonhydrostatic compression in steps is applied to transform crystalline zeolitic imidazolate framework‐62 into glass at room temperature. This method overcomes the limitations of existing approaches. This research reveals the mechanism of this phase transformation, including modifications in porosity, using various techniques, particularly positron ...
