Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films
Advanced Functional Materials, EarlyView.Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Hazy Days: Forest Fires and the Politics of Environmental Security in Indonesia
Journal of Current Southeast Asian Affairs, 2015 The Indonesian “haze†that engulfs Southeast Asia is a result of the burning of forests and has a detrimental effect on the health of millions of people. Indonesia is currently the third largest emitter of carbon dioxide in the world.

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries
Advanced Functional Materials, EarlyView.Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Generality, Specificity And Discovery [PDF]
This paper offers a meta-theory concerning the relation between the general and the specific in science. This issue was recently called back to attention by Hodgson (2001). A heuristic of discovery, developed in earlier work (Nooteboom 1992, 1996, 1999b,

Void elimination in screen printed thick film dielectric pastes [PDF]
, 1996 The problem is to understand the mechanisms for the formation and evolution of defects in wet screen printed layers. The primary objective is to know how best to alter the properties of the paste (rather than the geometry of the screen printing process ...
