The influence of d10-d10 interactions in Ag5Te1.8Se0.2Cl and Ag5Te1.6Se0.4Cl on structural and thermoelectric properties

open access: yes, 2011
Measurements of the thermopower and of the thermal diffusivity and a detailed analysis of the structural features by temperature-dependent single-crystal structure determinations of silver ionconducting Ag5Te1.8Se0.2Cl and Ag5Te1.6Se0.4Cl were performed ...

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.

Motives for and Against Engagement in Charity by Older Adults. Empirical Evidence from Poland

open access: yesFolia Oeconomica Stetinensia
Engagement in charity by society appears to be a vital issue. It is crucial due to the limited resources available for non-profit organizations. Older adults seem to be one of the groups that can support the non-governmental sector and may be involved in

Reversible property switching, thermoelectric performance, and d10−d10 interactions in Ag5Te2Cl

open access: yes, 2010
Thermoelectric and phase analytical measurements were performed to investigate the physical properties of trimorphic Ag5Te2Cl. The material is a mixed electron/silver ion conductor featuring drastic property changes during a silver order/disorder phase ...

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

open access: yesAdvanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

Comparison of Changes in Living Standards of Poland’S Population Across Different Classes of Location Over The Years 2000–2011

open access: yesFolia Oeconomica Stetinensia, 2014
The goal of this article is to verify the hypothesis that from 2000 to 2011 the discrepancies between material living standards in the countryside and cities of different sizes blurred in Poland year by year. On the basis of the research conducted it has

Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

open access: yesAdvanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

Preparation and characterization analysis of biofuel derived through seed extracts of Ricinus communis (castor oil plant)

open access: yesScientific Reports, 2022
The current study assesses the prospect of using R. Communis seed oil as a substitute fuel for diesel engines. Biodiesel is prepared from the R. Communis plant seed oil by a single-step base catalytic transesterification procedure.

Redox–transmetalation reactions: easy access to homo- and heterodimetallic d8,d10 complexes [PDF]

open access: yes, 2023
The ability of the imine PyCH═N–CH2Py (Py = 2-pyridyl, bpi) to behave as a heteroditopic ligand, which is suitable for creating two separate compartments to host metals in different oxidation states, has been developed by studying the reactions of the ...

Piezoresistivity Enhancement by Graphite Flake Alignment in Thin Composite Films for Dielectric Elastomer Switches

open access: yesAdvanced Robotics Research, EarlyView.
This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.
