De la Filosofía de la Tecnología a la Filosofía de la Ingeniería

open access: yesRevista Colombiana de Filosofía de la Ciencia, 2021
La creencia generalizada, heredada del inicio del siglo xx, dice que la ingeniería es la aplicación del conocimiento científico. Sin embargo, mediante la comprensión de los conceptos de técnica y tecnología, más allá de un asunto lingüístico, aparece la ...

WSPLK: A systematic approach to the thermodynamic characterization of light and heavy Mexican crude oil

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract A streamlined characterization framework (WSPLK) is presented for modelling complex reservoir fluids using cubic equations of state. The key methodological contribution is the introduction of a single global parameter ε directly into Pedersen's boiling‐point correlation, restoring pure‐component calibration and eliminating the need for ...

Development of a spatial projection map of glacial retreat based on vulnerability maps in the Central Cordillera, Peru

open access: yesJournal of Water and Climate Change
Increase in average global temperature over the last few decades has caused an accelerated retreat of tropical glaciers. Andean populations live in strict dependence on the water services provided by mountains and glaciers.

“Effects of High‐Intensity Ultrasound on the Structural, Technofunctional, and Allergenic Properties of Groundnut (Arachis hypogaea L.) Protein Isolates: A Review”

open access: yesFood Chemistry International, EarlyView.
ABSTRACT The growing global demand for sustainable, nutritionally balanced protein sources has intensified interest in plant‐derived proteins, particularly those derived from oilseeds such as groundnut (Arachis hypogaea L.). However, although groundnut protein isolates (GPIs) have high nutritional quality, they exhibit limitations in technofunctional ...

Engineering Crosslinker‐Free Sericin–Gelatin Hydrogels With Tunable Rheology for 3D Printing Applications

open access: yesJournal of Polymer Science, EarlyView.
Gelatin derived from porcine tissue and sericin extracted from Bombyx mori cocoons are combined to form crosslinker‐free hydrogels with tunable composition, enabling extrusion‐based 3D printing and biocompatible constructs for biomedical applications. ABSTRACT Hydrogels can be processed by 3D printing to manufacture tailor made structures, broadening ...

Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil

open access: yesSustainable Development, EarlyView.
ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing

Mechanochemical Fullerene Nanoencapsulation in Amino‐Functionalized ZIF‐12 for Visible‐Light Disinfection of Waterborne Viruses and Bacteria

open access: yesSmall, EarlyView.
A solvent‐minimized mechanochemical strategy enables the synthesis of C₆₀‐encapsulated amino‐functionalized ZIF‐12 as a visible‐light‐driven bifunctional photocatalyst. Synergistic charge separation enhances hydroxyl radical generation, achieving efficient viral in saline water and bacterial inactivation in river water under environmentally relevant ...

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.
