Oregon's nutria problem [PDF]

open access: yes, 1974
The nutria or coypu, Myocastor coypus, is a large semi-aquatic rodent that superficially resembles an overgrown muskrat or a stunted beaver. They were introduced into Oregon from about 1930 to the 1950's.

Detrapping and retrapping of free carriers in nominally pure single crystal GaP, GaAs and 4H-SiC semiconductors under light illumination at cryogenic temperatures

open access: yes, 2010
We report on extremely sensitive measurements of changes in the microwave properties of high purity non-intentionally-doped single-crystal semiconductor samples of gallium phosphide, gallium arsenide and 4H-silicon carbide when illuminated with light of ...

Electrochemical‐Doping of Tungsten on Nickel‐Boron‐Phosphide Microspheres for Accelerated Industrial‐Scale Water Electrolysis at High Current Density

open access: yesAdvanced Materials Technologies, EarlyView.
The bifunctional W/NiBP (+) || W/NiBP (−) demonstrates superior overall water splitting (OWS) performance as compared to the benchmark of Pt/C (+) || RuO2 (−). Notably, the W/NiBP (+, −) exhibits an ultra‐low cell voltage of 2.68 V at 2000 mA cm−2 high current density as compared to the benchmark value of 3.29 V.

Total immersion crystal growth [PDF]

open access: yes, 1987
Crystals of wide band gap materials are produced by positioning a holder receiving a seed crystal at the interface between a body of molten wide band gap material and an overlying layer of temperature-controlled, encapsulating liquid.

Electric Field Inhomogeneity in Colloidal QD‐LEDs

open access: yesAdvanced Optical Materials, Volume 13, Issue 19, July 4, 2025.
Variations in the thickness of the quantum dot (QD) active layer in a quantum dot light emitting diode leads to variations in the local electric field strength. Thicker regions insulate the QDs from the applied electric field. Under normal operating conditions, this leads to lower electroluminescence.

Ground squirrel damage and control in Montana [PDF]

open access: yes, 1978
The Columbian ground squirrel (Spermophilus columbianus), Richardson ground squirrel (Spermophilus richardsoni), and blacktail prairie dog (Cynomys ludovicianus) cause millions of dollars of loss to Montana agriculture each year.

Inflating hollow nanocrystals through a repeated Kirkendall cavitation process. [PDF]

open access: yes, 2017
The Kirkendall effect has been recently used to produce hollow nanostructures by taking advantage of the different diffusion rates of species involved in the chemical transformations of nanoscale objects.

Enhanced Stability of Cd‐Free Quantum Dot Light‐Emitting Diodes via Yttrium Acetate‐Modified ZnMgO: Suppressing Mg Migration

open access: yesAdvanced Optical Materials, EarlyView.
A surface passivation strategy using yttrium acetate to suppress Mg ion migration from the ZnMgO electron transport layer is proposed. This treatment restores oxygen vacancies on the ZnMgO surface, enhancing device stability. The Cd‐free quantum dot light‐emitting diodes demonstrate a 65.5% increase in operational lifetime with an external quantum ...
