25. Tear down academic paywall during pandemic
Zinc hexacyanoferrate (ZnHCF) is a Prussian Blue analog and can be intercalated by both monovalent and divalent ions. ZnHCF/multi-walled carbon nanotube (MWCNT) film could be used as a cathode for zinc ions battery. Carbon nanotubes improved significantly the electrochemical performance of the electrode. It is described the preparation of ZnHCF/MWCNT films b

27. Chemical and Spectroscopic Characteristics of Anthrosol (Amazonian Dark Earth) and Surrounding Soil from the Brazilian Amazon Forest: Evaluation of Mineral and Organic Matter Content by Depth
The chemical and spectroscopic characteristics of soil organic matter (SOM) isolated from Amazonian dark earth (ADE) and surrounding soil (SR) were evaluated according to the soil depth. The results showed opposite trends for the soils. While ADE featured SOM with a greater aromatic condensation degree and greater hydrophobicity in the top layer, the SR show

30. INCREASED ENERGY COGENERATION IN THE SUGAR-ENERGY SECTOR WITH THE USE OF SUGARCANE STRAW, ELECTRIFICATION OF DRIVES, AND HIGH-DRAINAGE ROLLERS IN THE EXTRACTION
ABSTRACT The sugar-energy sector stands out in the production of electrical energy in the Brazilian energy matrix. The updating of Law 9,427 allowed increasing the limit of power injected in the transmission or distribution systems of existing projects from 30 to 50 MW, encouraging studies of expansion and/or implementation of new cogeneration projects. This

31. Development and validation of a simple and rapid way to generate low volume of plasma to be used in point-of-care HIV virus load technologies
ABSTRACT A new point-of-care HIV viral load, mPIMA HIV-1/2 VL, Abbott, USA, has been recently developed. This point-of-care viral load requires no skilled person to run and uses a small plasma volume (50 µL). However, obtaining 50 µL of plasma can be a challenge in limited resource settings. We validated a simple and easy method to obtain enough amount of
