Mass Spectrometry Reviews, EarlyView.ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

An assessment of potential impact of alternative fluorocarbons on tropospheric ozone [PDF]
While the chlorofuorocarbons (CFCs) such as CFC-11 (CFCl3) and CFC-12 (CF2Cl2) are chemically inert in the troposphere, the hydrogen-containing halocarbons being considered as their replacements can, to a large extent, be removed in the troposphere by ...

Small, EarlyView.A patterned dual‐lubricant SLIPS creates interfacial energy asymmetry, guiding droplet migration without external actuation. Condensed droplets formed on the fluorinated‐oil‐infused regions migrate to the silicone‐oil‐infused domains, where rapid growth and coalescence occur.

Investigation of test methods, material properties and processes for solar cell encapsulants [PDF]
The potentially useful encapsulating materials for Task 3 of the Low-Cost Silicon Solar Array project were studied to identify, evaluate, and recommend encapsulant materials and processes for the production of cost-effective, long-life solar cell modules.

Small, EarlyView.A water drop slides over a distance of a few centimeters across arrays whose top surfaces exhibit a contact angle below 10°. The arrays are fabricated with hydrophilic tops and hydrophobic sidewalls and substrate, forming Janus structures. As the drop moves, it generates a spontaneous electric charge and leaves behind tiny satellite droplets that ...

Small Methods, EarlyView.Triboelectrification‐driven self‐assembly of dry colloidal powder offers a promising dry approach to rapidly (<20$<20$ s) attain ordered monolayer colloidal particles for surface‐enhanced Raman spectroscopy applications. ABSTRACT Surface‐enhanced Raman spectroscopy (SERS) amplifies Raman signals on nanostructured metallic surfaces, enabling the ...

The Tropospheric Lifetimes of Halocarbons and Their Reactions with OH Radicals: an Assessment Based on the Concentration of CO-14 [PDF]
Chemical reaction with hydroxyl radicals formed in the troposphere from ozone photolysis in the presence of methane, carbon monoxide and nitrogen oxides provides an important removal mechanism for halocarbons containing C-H and C = C double bonds.

Journal of Anatomy, EarlyView.In this study we show for the first time that the human basilar membrane contains elastin produced by the so‐called tympanic covering layer. It is believed to play an important functional role in human cochlear tuning, particularly low frequencies linked to our remarkable speech and music perception.

Assessment of effects on vegetation of degradation products from alternative fluorocarbons [PDF]
Concern with the effects of fluorides on plants has been devoted to that resulting from dry deposition (mainly with reference to gaseous HF and secondarily with particulate forms).

The Price of Prosperity? A Historical Account of Regulating Industrial Pollution in the Netherlands
Regulation &Governance, EarlyView.ABSTRACT Regulatory governance and state‐corporate crime studies link persistent industrial pollution to long‐term regulatory–industry interactions, yet little is known about how these interactions evolve and become entrenched. This article examines two enduring cases of industrial pollution in the Netherlands—Hoogovens/Tata Steel and DuPont de Nemours/
