Working Brigades, Hops Harvests and Hops Production in Czechoslovakia in 1945–1970

Kvasný průmysl, 2016
This article is an introduction of hops harvest working brigade phenomena. In Czechoslovakia there were thousands and thousands of youth who every year worked in hop-gardens. In the paper we can found an answer to question why and how the Czechoslovakian

The evaluation of α- and β-acid contents of Czech and Moravian hops from the 2011 harvest.

Kvasný průmysl, 2012
The contents of α- and β- acids from hops harvested in the Czech Republic in 2011 have been evaluated. The sampling was done in all three growing areas - Žatec (75.9 % of the hop yard areas in the Czech Republic), Úštěk (13.3 %) and Tršice (12.6 %).

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

Advanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

Advanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Technical Feasibility Study of Autonomous Field Robot‐Based on‐the‐go Assessment of Soil Nutrients Using Ion‐Sensitive Field‐Effect Transistors

Advanced Robotics Research, EarlyView.
Autonomous field robots equipped with ISFET‐based sensors enable rapid, spatially resolved soil nutrient analysis directly in the field. An automated system based on the BoniRob platform is presented for standardized on‐site extraction and measurement of key macronutrients and soil pH.

Investigating the impact of on-bine maturity on the chemical, biochemical, and sensorial characteristics of Citra® hops.

Food Chemistry
Decisions on when to harvest hops are crucial for hop growers and brewers, as maturity has been shown to affect hop quality. This study examined Citra® hop quality with weekly harvests at seven time points from three Yakima Valley, WA fields over three ...

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...
