Heat Isolators on a Vacuum Flask [PDF]

open access: yes, 2010
The thing which makes the vacuum flask system useful is the vacuum between the two bottles. Producers of the vacuum flask try to create a perfect vacuum between the two bottles, but it is impossible. Little air goes inside, too.

Leveraging Life Cycle Assessment for Informing Packaging Eco‐Design and Eco‐Modulation

open access: yesSustainable Development, EarlyView.
ABSTRACT Eco‐modulation is designed to promote the adoption of eco‐design. However, in practice, its application is mostly concentrated on end‐of‐life (EoL) optimization. This study addresses the gap by proposing a framework to assess product–packaging systems as integrated units throughout the full life cycle.

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

open access: yessteel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

open access: yesStructural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

open access: yesStructural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...
