Comparison of quality parameters of Czech and foreign hop varieties
Plant, Soil and Environment, 2003 Market varieties of hops are classified to several groups according to their use in the brewing industry - aroma, bitter (dual-purpose), high-alpha ones. Saaz and other genetically related varieties form a separate group among the aromatic hops.

Dynamics of Isomerization of Hop Alpha-Acids and Transition of Hop Essential Oil Components in Beer
Acta Chimica Slovenica, 2020 Hops’ unique composition of essential oil components and bitter resins are crucial for beer aroma, which is important to consumers’ acceptance of beer. In this experiment the same wort was divided into four portions and each was hopped differently.

“DELTA RESIN,” A WATER-SOLUBLE, BITTER, BACTERIOSTATIC PORTION OF THE RESIN OF HOPS [PDF]
Journal of the Institute of Brewing, 1952 When humulone is heated at 98–100° C. in a stream of oxygen, it is gradually converted to resinous material which is soluble in water, ether, methanol, ethanol and acetone, but insoluble in light petroleum and in benzene. The aqueous solution of this resin has a pleasant bitter taste and yields a lead salt when mixed with an aqueous solution of lead ...

Advanced Engineering Materials, EarlyView.To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

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 ...

Advanced Science, EarlyView.ABSTRACT Bile acids have been implicated in calcium oxalate (CaOx) nephrolithiasis. Here, we employ multi‐omics approaches to identify isoallolithocholic acid (isoalloLCA) as the key bile acid elevated in the feces, serum, kidney, and urine of CaOx rats, confirmed by spatial metabolomics.
