Inactivation of Coxiella burnetii by Gamma Irradiation

Microbiology, 1989
The gamma radiation inactivation kinetics for Coxiella burnetii at -79 degrees C were exponential. The radiation dose needed to reduce the number of infective C. burnetii by 90% varied from 0.64 to 1.2 kGy depending on the phase of the micro-organism, purity of the culture and composition of suspending menstruum.

Exploration of Pseudobinary Alloys (Al–Mn)‐(Co–Fe–Ni) to Design High‐Entropy and Compositionally Complex Alloys to Stabilize the τ Phase in Al–Mn‐Based Ferromagnetic Alloys

Advanced Engineering Materials, EarlyView.
This experimental study investigates the thermodynamic limits of the Al–Mn τ ferromagnetic phase within complex‐composition alloys (CCAs). Using nine rare‐earth‐free compositions, it explores a broad region of the pseudobinary AlMnCoFeNi system. The results reveal intricate links between composition, phase stability, and magnetic behavior, highlighting

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Effect of gamma irradiation on the mechanical properties of PVC/ZnO polymer nanocomposite

, 2017
Polyvinyl Chloride (PVC) based nanocomposite with different weight ratios of Zinc oxide (ZnO) nanoparticles is prepared by using a gel-like technique. The weight-ratio of ZnO nanoparticles, in a range of 2.5–10 wt%, is used to prepare nanocomposites' in ...

The Effect of Gamma Irradiation on the Physiochemical Properties of Caesium-Selective Ammonium Phosphomolybdate-Polyacrylonitrile (AMP-PAN) Composites

, 2019
Managing certain by-products of the nuclear fuel cycle, such as the radioactive isotopes of caesium: Cs-134, Cs-135 and Cs-137 is challenging due to their environmental mobility and radioactivity.

Advanced Electron Microscopy and Microcomputed Tomography Analysis of Single‐Crystal Ni‐Base Superalloys After Short‐Term Multiaxial Creep

Advanced Engineering Materials, EarlyView.
This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Comparison of radiosensitivity response to acute and chronic gamma irradiation in colored wheat

Genetics and Molecular Biology, 2018
We aimed to investigate the biological responses induced by acute and chronic gamma irradiation in colored wheat seeds rich in natural antioxidants. After acute and chronic irradiation, the phenotypic effects on plant growth, germination rate, seedling ...

Effect of gamma-irradiation on fish meal.

Agricultural and Biological Chemistry, 1983
The irradiation effect on components of a commercial fish meal and their storage effect were investigated. The numbers of contaminating microorganisms in the fish meal were as follows : total aerobic bacteria, 3.5×105 ; coliforms, 1.4×103 ; osmophilic moulds, 4.8×102 ; and fungi, 2.8×102 per gram.
