Aromatic Polyimine‐Derived Carbon Membranes for Efficient Hydrogen Separation

open access: yesSmall, EarlyView.
A polyimine with free‐volume‐introducing kinked structures was used as a precursor for high‐performance carbon membranes. Changing the pyrolysis protocol affects the carbon structure, yielding membranes with high permeance and enhanced selectivity for key industrial gas pairs (H2/N2, H2/CH4), offering a practical route toward efficient and reliable ...

Freeform Nanopatterning of Hydrogel Surfaces

open access: yesSmall Methods, EarlyView.
We present a method for fabricating grayscale surface topographies with nanometer‐scale features on hydrogel surfaces. Patterns are transferred from a silicon wafer to a hydrogel via replica molding. Controlled dehydration induces hydrogel shrinkage, miniaturizing the original structures.

Influence of calcination temperature on the durability of metakaolin concrete and limitations of conventional testing methods

open access: yesStructural Concrete, EarlyView.
Abstract Incorporating metakaolin (MK) as a partial cement replacement offers a viable pathway to reduce carbon emissions while improving concrete performance. However, its durability behavior remains inconsistent, and the applicability of durability test methods to MK‐based concrete is not well established.

Closed‐form solutions for dynamic punching shear assessment in flat slabs subjected to sudden column removal

open access: yesStructural Concrete, EarlyView.
Abstract Simplified closed‐form equations are commonly used in structural design to prevent punching shear failures of concrete flat slabs supported on columns in permanent and transient situations, whereas more advanced methods are generally used in verifications at accidental design situations due to the lack of suitable equivalent approaches ...
