Dataset of Fourier transform infrared (FTIR) spectra of a primary amine, selected aldehydes, and their Schiff bases acquired using the Invenio-R spectrometer.

This dataset reports on the Fourier-transform infrared (FTIR) spectroscopic analysis of a primary amine and some aldehydes along their corresponding Schiff bases. The dataset presented in this work consists of spectral FTIR data acquired in the 80-6000 cm⁻¹ range, along with the corresponding relative IR intensities of the samples. The primary amine and aldehydes were of high purity and were used to synthesise the corresponding Schiff bases.

Trend of Polymer Research Related to COVID-19 Pandemic: Bibliometric Analysis.

Polymeric materials are used for personal protective equipment (PPE), which is mandatory for clinicians to use when handling coronavirus disease 2019 (COVID-19) patients. The development of diagnostic tools and vaccines for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is also dependent on polymer technology. This current report aims to provide readers with the trend of polymer research regarding the COVID-19 pandemic, by employing bibliometric analysis.

Cacao Pod Husk Extract Phenolic Nanopowder-Impregnated Cellulose Acetate Matrix for Biofouling Control in Membranes.

The ultrafiltration membrane process is widely used for fruit juice clarification, yet the occurring of fouling promotes a decline in process efficiency. To reduce the fouling potential in the membrane application in food processing, the use of natural phenolic compounds extracted from cocoa pod husk is investigated. The cocoa pod husk extract (CPHE) was prepared in phenolic nanoparticles form and added into the polymer solution at varying concentrations of 0.

Synthesis of Polyurethane Membranes Derived from Red Seaweed Biomass for Ammonia Filtration.

The development of membrane technology is rapidly increasing due to its numerous advantages, including its ease of use, chemical resistant properties, reduced energy consumption, and limited need for chemical additives. Polyurethane membranes (PUM) are a particular type of membrane filter, synthesized using natural organic materials containing hydroxy (-OH) groups, which can be used for water filtration, e.g.

Development of Chitosan/Starch-Based Forward Osmosis Water Filtration Bags for Emergency Water Supply.

A forward osmosis (FO) membrane was developed from a mixture of chitosan and starch, cross-linked using glutaraldehyde. The cross-linked chitosan/starch membrane was revealed to have high mechanical properties with an asymmetric structure. The prepared membrane's performance was investigated as an FO filter assembled in a polypropylene water filter bag and aluminum foil plastic.

Facile Approaches of Polymeric Face Masks Reuse and Reinforcements for Micro-Aerosol Droplets and Viruses Filtration: A Review.

Since the widespread of severe acute respiratory syndrome of coronavirus 2 (SARS-CoV-2) disease, the utilization of face masks has become omnipresent all over the world. Face masks are believed to contribute to an adequate protection against respiratory infections spread through micro-droplets among the infected person to non-infected others. However, due to the very high demands of face masks, especially the N95-type mask typically worn by medical workers, the public faces a shortage of face masks.

A novel approach for blood purification: mixed-matrix membranes combining diffusion and adsorption in one step.

Hemodialysis is a commonly used blood purification technique in patients requiring kidney replacement therapy. Sorbents could increase uremic retention solute removal efficiency but, because of poor biocompatibility, their use is often limited to the treatment of patients with acute poisoning. This paper proposes a novel membrane concept for combining diffusion and adsorption of uremic retention solutes in one step: the so-called mixed-matrix membrane (MMM).
