Plasticizers01:31

Plasticizers

156
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Threats to Biodiversity

24.7K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Types of Toxins

2.7K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

Plastic Behavior01:21

Plastic Behavior

335
A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and...

Global Climate Change

27.0K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Plastic Deformations01:19

Plastic Deformations

235
Plastic deformation represents a fundamental concept in materials science, which explains the irreversible change in the shape of a material when it experiences stress beyond its elastic capability. This phenomenon is important in structural engineering, especially in designing and analyzing cantilever beams—structures that are securely fixed at one end and bear loads at the opposite end. When these beams are subjected to loads within their elastic range, they will return to their...

Área de la Ciencia:

  • Ciencias del medio ambiente
  • Ecotoxicología
  • Recuperación medioambiental

Sus antecedentes:

  • La contaminación por plásticos plantea un importante desafío medioambiental debido a su persistencia.
  • El plástico acumulado en los ecosistemas es a menudo "poco reversible", lo que significa que la degradación natural es lenta y la remediación es difícil.

Objetivo del estudio:

  • Definición de la contaminación plástica "poco reversible".
  • Describir las repercusiones ambientales y sociales potenciales de dicha contaminación.
  • Proponer estrategias racionales para hacer frente a esta amenaza global.

Principales métodos:

  • Análisis conceptual de la persistencia y la reversibilidad del plástico en contextos ambientales.
  • Identificación de las posibles consecuencias ecológicas y sociales.
  • Formulación de estrategias de respuesta basadas en las características de la contaminación.

Principales resultados:

  • La contaminación plástica se considera "poco reversible" cuando la mineralización natural es lenta y las soluciones de ingeniería son improbables.
  • Dicha contaminación puede conducir a resultados negativos irreversibles, incluidos los ciclos biogeoquímicos alterados, la degradación del hábitat, la ecotoxicidad y los impactos en las especies clave.
  • Las repercusiones sociales son también una preocupación importante.

Conclusiones:

  • La acumulación de contaminación plástica poco reversible presenta una amenaza grave y prácticamente irreversible.
  • Se requiere una acción global urgente, centrada en la reducción del consumo de plástico virgen.
  • Las estrategias de gestión de residuos coordinadas a nivel internacional son esenciales para la mitigación.
