TanDEM-X for Large-Area Modeling of Urban Vegetation Height: Evidence from Berlin, Germany

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2016
Large-area urban ecology studies often miss information on vertical parameters of vegetation, even though they represent important constituting properties of complex urban ecosystems.

Lake Restoration: Medical Lake, Washington

Journal of Freshwater Ecology, 1981
ABSTRACT For several decades the thick algal scums and offensive odors of Medical Lake have limited its use. High phosphorus levels, resulting from internal cycling of the nutrient, were responsible for the excessive algal growth. Disruption of the cycle was achieved by whole-lake applications of aluminum sulfate.

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

Advanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

High carbon emissions from thermokarst lakes of Western Siberia

Nature Communications, 2019
The Western Siberia Lowland (WSL), the world’s largest permafrost peatland, is of importance for understanding the high-latitude carbon (C) cycle and its response to climate change.

Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

Harmonizing the Pyrene and Ether Groups in Covalent Triazine Polymers for Highly Effective H2O2 Photosynthesis via One‐Step Two‐Electron Oxygen Reduction

Advanced Functional Materials, EarlyView.
The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

Molecular composition of organic matter controls methylmercury formation in boreal lakes

Nature Communications, 2017
A detailed understanding of the formation of the potent neurotoxic methylmercury is needed to explain the large observed variability in methylmercury levels in aquatic systems.

Muskoka Lakes project 1986 progress report: Lake Muskoka, Lake Joseph, Lake Rosseau, Lake of Bays

, 1988
This progress report summarizes the 1986 lake chemistry data for Lake Muskoka, Lake Joseph, Lake Rosseau and Lake of Bays. The nutrient levels show that the lakes are oligotrophic. The alkalinity data indicates the lakes are moderately sensitive to acidic deposition.

Multiple Twinning in Nacre and Aragonite

Advanced Functional Materials, EarlyView.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.
