Preparação e caracterização de blendas elastoméricas totalmente verdes [PDF]
, 2021 In this work, blends of starch, carboxymethyl cellulose and hydroxypropyl methylcellulose with latex were produced and characterized according to their physicochemical properties. The blends were prepared in the proportions in percentage of 12.5%/87.5%; 25%/75%; 37.5%/62.5%; 50%/50%; 62.5%/37.5%; 75%/25%; 87.5%/12.5%.

Avaliação de blendas de PAN/polímeros biodegradáveis por calorimetria [PDF]
Matéria (Rio de Janeiro), 2012 Blendas de copolímero de poliacrilonitrila (PAN) com polímeros biodegradáveis foram obtidas pelo método convencional da indústria plástica de processamento via extrusão. O processo de produção destes materiais em extrusora convencional era um método que até pouco tempo atrás era inviável de se produzir, devido ao fato do polímero de PAN iniciar um ...

A review on egg pasteurization and disinfection: Traditional and novel processing technologies
Comprehensive Reviews in Food Science and Food Safety, Volume 22, Issue 2, Page 756-784, March 2023., 2023 Abstract Salmonella Enteritidis is a pathogen related to many foodborne outbreaks involving eggs and egg products. Regulations about whether eggs should be pasteurized are very different and inconsistent worldwide. In the United States, eggs are not required to be pasteurized. Hence, less than 3% of the eggs in the country are pasteurized. The standard

Energy Technology, Volume 10, Issue 8, August 2022., 2022 Recently, non‐fullerene acceptors (NFAs) have revolutionized organic photovoltaics (OPVs) research. Three star‐shaped NFAs are herein reported and tested in flexible OPVs upon blending with the standard P3HT donor. The molecules have different terminal units (indene malononitrile and barbiturate) and one or two thiophene spacers. The most promising NFA

Cibalackrot Dendrimers for Hyperfluorescent Organic Light‐Emitting Diodes
Macromolecular Rapid Communications, Volume 43, Issue 16, August 2022., 2022 1st‐Generation Cibalackrot dendrimers with new highly‐twisted mesityl dendrons are synthesized, enabling high solubility and low aggregates in blend films. Hyperfluorescent dendrimer organic light‐emitting diodes (OLEDs) are first demonstrated to process external quantum efficiencies (EQEs) of >10% (@ 100 cd m−2), high current densities (>200 mA cm−2),

DEHT is a suitable plasticizer option for phthalate‐free storage of irradiated red blood cells
Vox Sanguinis, Volume 117, Issue 2, Page 193-200, February 2022., 2022 Abstract Background and Objectives Due to increasing concerns about possible endocrine‐disrupting properties, the use of the plasticizer di(2‐ethylhexyl) phthalate (DEHP) will be banned in future blood storage. Di(2‐ethylhexyl) terephthalate (DEHT) provides sufficient red blood cell (RBC) quality during conventional blood bank storage.

Journal of Medical Virology, Volume 93, Issue 7, Page 4592-4596, July 2021., 2021 Abstract With the emergence of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), a need for diagnostic tests has surfaced. Point‐of‐care (POC) antibody tests can detect immunoglobulin (Ig) G and M against SARS‐CoV‐2 in serum, plasma, or whole blood and give results within 15 min. Validation of the performance of such tests is needed if they
