Environmental Levels and Human Body Burdens of Per- and Poly-Fluoroalkyl Substances in Africa: A Critical Review
(Elsevier, 2020-06-05)
Per- and polyfluoroalkyl substances (PFASs) are known organic pollutants with adverse health effects on humans and the ecosystem. This paper synthesises literature about the status of the pollutants and their precursors, ...
Magnetocaloric Effect and Sign Reversal of Magnetic Entropy Change Across the Spin Reorientation Temperature in R3Fe5O12 (R = Gd, Dy)
(Elsevier, 2020-04-15)
The cubic structure with space group Ia3‾d for Gd3Fe5O12 and Dy3Fe5O12 are successfully synthesized and the magnetic behaviors are studied in details. The dc magnetization measurements show that an obvious negative ...
Spin Reorientation, Normal and Inverse Magnetocaloric Effects in Heavy Rare-Earth Iron Garnets
(Elsevier, 2020-08-01)
Experiments for heavy rare-earth iron garnets Ho3Fe5O12 and Er3Fe5O12 show a compensation effect characterized by a near zero magnetization at 134 K and 80 K, respectively. The magnetic entropy change calculated according ...
Use of Semiochemicals for Surveillance and Control of Hematophagous Insects
(Chemoecology, 2020-06-23)
Reliance on broad-spectrum insecticides and chemotherapeutic agents to control hematophagous insect vectors, and their related diseases is threatened by increasing insecticide and drug resistance, respectively. Thus, ...
