Hiding the cosmological constant
, 2019 Perhaps standard effective field theory arguments are right, and vacuum fluctuations really do generate a huge cosmological constant. I show that if one does not assume homogeneity and an arrow of time at the Planck scale, a very large class of general ...

CFD Analysis of Dual‐Layer PCM Roofs for Thermal Mitigation in Residential Buildings
Heat Transfer, EarlyView.ABSTRACT This study presents a computational fluid dynamics analysis of dual‐layer phase change material (PCM) roofs for passive cooling in residential buildings under the hot and humid climate of Bangladesh. A three‐dimensional transient model was developed in ANSYS Fluent using the enthalpy–porosity approach to simulate coupled heat conduction ...

Concrete Pavement Mixture Design and Analysis (MDA): Evaluation of Foam Drainage Test to Measure Air Void Stability in Concrete [PDF]
, 2015 The stability of air bubbles in fresh concrete can have a profound influence of the potential durability of the system, because excessive losses during placement and consolidation can compromise the ability of the mixture to resist freezing and thawing ...

Interdisciplinary Materials, EarlyView.Since solid‐state sodium batteries (SSSBs) are a promising solution for advancing sodium‐based energy storage, it is necessary to systematically summarize the development process of SSSBs. It focuses on the role of interface engineering in addressing challenges such as materials design, interfacial strategies, and multiscale characterization.

Interdisciplinary Materials, EarlyView.An electron‐donating Ni3N interlayer enables selective anion gating, suppressing Cl− corrosion while preserving OH− reactivity. The resulting seawater oxygen evolution reaction (OER) catalyst achieves 2.12 V at 1000 mA cm−2 and ~550 h stability. This generalizable strategy improves the durability of diverse catalysts by 2–10x.
