RCA SATCOM Battery in Orbit Performance Update and Accelerated Life Test Results [PDF]

open access: yes, 1984
No significant degradation of nickel cadmium battery performance in SATCOM F1 and F2 after almost 8 and 7-3/4 years in orbit was shown. Battery minimum discharge voltage data are presented for these spacecraft.

All‐Cellulose‐Based Photonic Glitters

open access: yesAdvanced Functional Materials, EarlyView.
Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

Characterization of physio-chemical properties of polymeric and electrochemical materials for aerospace flight [PDF]

open access: yes
Sealed nickel cadmium cells having undergone a large number of cycles were discharged using the Hg/HgO reference electrode. The negative electrode exhibited the second plateau.

High-energy exciton transitions in quasi-two-dimensional cadmium chalcogenide nanoplatelets

open access: yes, 2017
Semiconductor nanoparticles of cadmium chalcogenides are known to exhibit pronounced thickness-dependent $E_0$ series of exciton transitions at the $\Gamma$ point of the Brillouin zone (BZ).

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

open access: yesAdvanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Tailoring Hole‐Blocking Layers Enables a Versatile Approach for Fast Photomultiplication‐Type Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates the role of hole‐blocking layers (HBLs), particularly the combination of two HBLs in photomultiplication‐type organic photodetectors (PM‐OPDs), which results in high gain and record‐fast response. The proposed HBL strategy also allows for the use of photoactive layer with balanced donor–acceptor stoichiometry, which can be ...
