Reduced sea ice protection period increases storm exposure in Kivalina, Alaska

Arctic Science, 2018
On Arctic coasts, erosion is limited by the presence of nearshore sea ice, which creates a protective barrier from storms. In Kivalina, an Alaskan Inupiaq Inuit community, decreasing seasonal sea ice extent and a lengthening of the open-water season may ...

Unlocking High‐Performance in All‐Organic Solar Cells by the Development of Organic Electrodes with No Acid and High‐Temperature Treatment and the Effective Preparation Thereof on Organic Multilayer Films

Advanced Functional Materials, EarlyView.
The developed all‐organic solar cells achieve a power conversion efficiency of 8.7%, more than double the previous record. In addition, bioplastic substrates are used to produce environmentally friendly solar cells with an efficiency of 8.6%. These results are achieved by developing high‐performance organic electrodes without acid doping or high ...

Enhancing UV Stability and Charge Extraction in Organic Solar Cells with Phenyl‐Linked Aromatic Self‐Assembled Monolayer

Advanced Functional Materials, EarlyView.
The phenyl‐linked self‐assembled monolayer exhibits robust intrinsic stability and hole extraction capability compared to the alkyl‐linked counterparts, thus facilitating the device stability with T80 over 1000 h and efficiency of 19.7% in advancing organic solar cells.

Enriching Surface‐Accessible CO2 in the Zero‐Gap Anion‐Exchange‐Membrane‐Based CO2 Electrolyzer

Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
A descriptor called the surface‐accessible CO2 concentration ([CO2]SA) is developed, which enables to indicate the transient state of the local [CO2]/[OH−] ratio and helps define the limits of CO2‐to‐CO conversion. Three general tactics are developed to enrich [CO2]SA for high current electrolysis: (1) increasing the catalyst layer thickness, (2 ...

Protura in Arctic Regions, with Description of Mastodonentomon n. gen. (Acerentomidae, Nipponentominae) and a Key to Known Arctic Taxa

Insects, 2020
Protura are widespread, but their presence in the Arctic was first noted only ca. 70 years ago and is still little acknowledged. This work compiles taxonomic information on proturans in the Arctic regions and adds unpublished data from Northern Siberia ...

Multiplier Sequences for Generalized Laguerre Bases [PDF]

The Rocky Mountain J. of Math., {\bf 43} (4), 2013, 1141-1159, 2010
In this paper we present a complete characterization of geometric and linear multiplier sequences for generalized Laguerre bases. In addition, we give a partial characterization of the generic multiplier sequence for such bases, and pose some open questions regarding polynomial type multiplier sequences.

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Engineering Novel DNA Nanoarchitectures for Targeted Drug Delivery and Aptamer Mediated Apoptosis in Cancer Therapeutics

Advanced Functional Materials, EarlyView.
Designer DNA Architecture‐templated Drug Conjugates (DDA‐DCs) are comprised of a DNA nanomaterial decorated with multiple drug‐loaded DNA aptamers. DDA‐DCs use a combination of multiple aptamer types, each recognizing a different membrane protein to achieve precise targeting of cancer cells.

The complete mitogenome of the rockweed Fucus distichus (Fucaceae, Phaeophyceae)

Mitochondrial DNA. Part B. Resources, 2017
The rockweed F. distichus is a one of the most common intertidal seaweeds in the northern hemisphere. The systematics of F. distichus however remains open to discussion. Here, we contribute to the bioinformatics and systematics of F.
