Incorporating Nanoparticles in Porous Foam Templating for Enhanced Sensitivity of Capacitive Pressure Sensors

open access: yesAdvanced Sensor Research, Volume 3, Issue 5, May 2024.
This work introduces the incorporation of silica nanoparticles (SNPs) in the templating process of porous foams for capacitive pressure sensors. The SNPs change the microstructures and porosity of the foams, which results in significant enhancement of sensitivity for pressures below 2 kPa, leading to linearization of sensitivity of the pressure sensor ...

ATPase mechanism of the 5'-3' DNA helicase, RecD2: evidence for a pre-hydrolysis conformation change [PDF]

open access: yes, 2013
The superfamily 1 helicase, RecD2, is a monomeric, bacterial enzyme with a role in DNA repair, but with 5'-3' activity unlike most enzymes from this superfamily. Rate constants were determined for steps within the ATPase cycle of RecD2 in the presence of

tRNA 3\u27-amino-tailing for stable amino acid attachment. [PDF]

open access: yes, 2018
Amino acids are attached to the tRNA 3\u27-end as a prerequisite for entering the ribosome for protein synthesis. Amino acid attachment also gives tRNA access to nonribosomal cellular activities.

Current Approaches on Natural Fiber Reinforcement Surface Treatment for Construction Material Application

open access: yesInternational Journal of Polymer Science, Volume 2024, Issue 1, 2024.
The conversion of waste into value‐added products is critical to long‐term sustainability as waste disposal costs, landfilling space, and climate change would be reduced. Research and production industries investigate the possible use of natural fibers as a substitute for fossil fuels.

PRODUÇÃO DE ETANOL DE SEGUNDA GERAÇÃO PROVENIENTE DO BAGAÇO DE PENDÚCULOS DO CAJU

open access: yesRevista Caatinga, 2015
The use of cashew apple bagasse for bioethanol production aimed at taking advantage of a re-gional culture that has about 85% of waste. Due to the complex structure of the material, it is necessary to sub-mit it to physical pretreatments and/or chemicals

An Effective Sol‐Gel‐Functionalized Polyurethane Foams Solid Platform Packed Minicolumns for Complete Extraction of Chromium (VI) from Water: Kinetic, Sorption Isotherms, Thermodynamic Study, and Analytical Utility

open access: yesInternational Journal of Analytical Chemistry, Volume 2024, Issue 1, 2024.
In the modern era, sol‐gel plays a key role in the progress of a new generation of dispersive solid‐phase microextractors (d–µ SPMEs) for the removal of organic and inorganic pollutants in complex matrices. Thus, the current study reports the use of sol‐gel‐functionalized polyurethane foams (PUFs) as a novel solid platform for complete extraction of ...
