Polyethylene-Glycol-Modified Halide Perovskite for Enhancing the Switching Ratio and Cycling Stability of Resistive Random Access Memory

open access: yes, 2023
As a result of the apparent hysteresis caused by ion migration, halide perovskites (HPs) are used as the active layer of resistive devices. Here, polyethylene glycol (PEG) is used to form an organic network in the Cs3Bi2Br9 precursor solution to ...

Methods for microbial DNA extraction from soil for PCR amplification

open access: yesBiological Procedures Online, 1998
Amplification of DNA from soil is often inhibited by co-purified contaminants. A rapid, inexpensive, large-scale DNA extraction method involving minimal purification has been developed that is applicable to various soil types (1).

Bacteriophage Precipitation with Polyethylene Glycol (PEG)

open access: yes, 2023
Abstract This protocol can be employed to both purify and concentrate bacteriophages (phages) after their production. As a hygroscopic substance, polyethylene glycol in combination with its co-precipitant sodium chloride binds water molecules leading to the precipitation of the phages.
