Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...

Analysis of Water Vapor Characteristics During Heavy Snow in Different Warm Regions of Northern Xinjiang

open access: yesGaoyuan qixiang
This thesis analyzed the data with NCEP/NCAR method, took HYSPLIT (Lagrangian forward trajectory) method to simulate water vapor characteristics of 27 winter snowstorms in northern Xinjiang from 1980 to 2020, and also analyzed the source-sink ...

The Population Status of Cardііdae (Bіvalvіa) as a Bioindicator for Water Quality in the North-western Part of the Sea of Azov [PDF]

open access: yes, 2016
An attempt was made to evaluate the suitability of using mollusc populations from the family Cardiidae as a biological indicator to monitor ecological water quality in the north-western part of the Sea of Azov.

An Energy Focusing Flexible and Lightweight Acoustic Metamaterial for Enhanced Ultrasound Power Transfer

open access: yesAdvanced Materials, EarlyView.
A flexible and lightweight acoustic metamaterial composed of air cavities encased in polydimethylsiloxane (PDMS) is introduced to enhance ultrasound power transfer. The metamaterial leverages the strong reflectivity of air cavity boundaries to concentrate incoming ultrasound, thereby improving the performance of piezoelectric energy harvesters ...

Textiles from Scythian burial complexes

open access: yesTyragetia, 2013
In Northern Black Sea steppes were excavated more than three thousand Scythian burial mounds. In the studied burials were discovered large quantities of artifacts, but leather and textile items are preserved only in a few cases. Some ideas about Scythian

The Marmara Sea Gateway since ~16 ky BP: non-catastrophic causes of paleoceanographic events in the Black Sea at 8.4 and 7.15 ky BP [PDF]

open access: yes, 2007
The Late Quaternary history of connection of the Black Sea to the Eastern Mediterranean has been intensely debated. Ryan, Pitman and coworkers advocate two pulses of outflow from the Black Sea to the world ocean at ~16–14.7 ky BP and ~11–10 ky BP ...

The age and origin of the central Scotia Sea [PDF]

open access: yes, 2010
Opening of the Drake Passage gateway between the Pacific and Atlantic oceans has been linked in various ways to Cenozoic climate changes. From the oceanic floor of Drake Passage, the largest of the remaining uncertainties in understanding this opening is

Electric‐Current‐Assisted Nucleation of Zero‐Field Hopfion Rings

open access: yesAdvanced Materials, EarlyView.
This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external

BLOC: Buildable and Linkable Organ on a Chip

open access: yesAdvanced Materials Technologies, EarlyView.
We developed a “Buildable and Linkable Organ on a Chip” (BLOC) that can construct diverse microphysiological systems (MPSs). The BLOC is standardized to the same size and has one of the functions of “Culture,” “Control,” or “Analysis.” Users can freely configure various MPSs, including developing perfusion, cytotoxicity analysis, and biochemical ...
