Next‐Generation Aerogel Electrocatalysts for Oxygen Reduction Reaction
Small, EarlyView.ABSTRACT Aerogel‐based electrocatalysts have become a groundbreaking class of materials for the oxygen reduction reaction (ORR), distinguished by their ultralight nature, pore networks, and outstanding electrical conductivity. Their interconnected three‐dimensional frameworks offer abundant active sites, efficient diffusion channels, and continuous ...

Lightweight aggregates for structural concrete [PDF]
, 1955 "April 8, 1955.""Reprinted from the Proceedings of the AMERICAN SOCIETY OF CIVIL ENGINEERING, Vol. 81, January 1955.""In recent years interest in lightweight concrete has become widespread, not only on account of its light weight, which is desirable in ...

Dynamics of loop quantum gravity and spin foam models in three dimensions
, 2004 We present a rigorous regularization of Rovellis's generalized projection operator in canonical 2+1 gravity. This work establishes a clear-cut connection between loop quantum gravity and the spin foam approach in this simplified setting.

International Journal of Urban and Regional Research, EarlyView.Abstract The Beqaa Valley in Lebanon has become increasingly polluted, and residents are attributing illness to improper waste disposal and dumping. This article explores local epistemologies of pollution’s causes and effects in three films, which were researched and produced by local residents of Bar Elias, a small town in the Beqaa, which has rapidly

Regularization and finiteness of the Lorentzian LQG vertices
, 2009 We give an explicit form for the Lorentzian vertices recently introduced for possibly defining the dynamics of loop quantum gravity. As a result of so doing, a natural regularization of the vertices is suggested.

Macau as Method: Recombinant Urbanism in Post‐Socialist China
Asia Pacific Viewpoint, EarlyView.ABSTRACT In ‘Asia as Method’, Chen Kuan‐Hsing argues for the value of an indigenous inter‐Asian approach to analysing the effects of European imperialism on the countries and citizens of Asia. This article mobilises both Chen's inter‐Asian referencing strategy and the city‐state of Macau to explore Macau's role in China's engagements with global ...
