Investigation of electrical noise in selenium-immersed thermistor bolometers [PDF]

open access: yes
The selenium immersed, thermistor bolometer, IR detector failed due to spurious and escalating electrical noise outburst as a function of time at elevated temperatures during routine ground based testing in a space simulated environment.

Theoretical and Experimental Investigation of the Ligand‐Directed Assembly and Photovoltaic Performance of PbSe Nanorods

open access: yesAdvanced Materials Interfaces, EarlyView.
This study delves into the critical role of ligand type on morphology, photophysical behavior, and optoelectronic performance of PbSe Nanorods (NRs). A combination of computational modelling and experimental techniques reveals that EDT‐capped PbSe NRs exhibit well‐ordered packing with strong interfacial coupling and improved optoelectronic performance.

Development of ZnO Buffer Layers for As‐Doped CdSeTe/CdTe Solar Cells with Efficiency Exceeding 20%

open access: yesAdvanced Materials Technologies, EarlyView.
Highly resistive ZnO has been used as the buffer layer in As‐doped CdSeTe/CdTe solar cells to achieve efficiencies higher than 20%. STEM images and EDX mapping show that the quality of the front interface is dependent on the ZnO deposition temperature. Unusually, chlorine is not observed at the front interface using EDX when the ZnO is deposited at 100

Discovery of Zinc, Selenium, Bromine, and Neodymium Isotopes [PDF]

open access: yesarXiv, 2010
Currently, thirty-two zinc, thirty-two selenium, twenty-nine bromine and thirty-one neodymium isotopes have been observed and the discovery of these isotopes is discussed here. For each isotope a brief synopsis of the first refereed publication, including the production and identification method, is presented.

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 ...

Emerging Therapeutic Strategies for Hearing Loss

open access: yesAdvanced Therapeutics, EarlyView.
Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or

Management of trace elements and vitamins in organic ruminant livestock nutrition in the context of the whole farm system [PDF]

open access: yes, 2008
There is a wealth of information on the vital role of trace minerals in ruminant health. This information gives some reasonable indications of the levels required by dairy and beef animals to maintain good health though there is much less information ...
