Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

open access: yesAdvanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Shaping of Biohybrid Functional Living Materials

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates a strategy for shaping living mycelium into functional materials by directing its natural growth. Nanoparticles armor hyphae, micron‐scale particles entangle within the network, and printed hydrogel architectures steer expansion, creating defined geometries.

Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes

open access: yesAdvanced Functional Materials, EarlyView.
The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

First to Score, First to Win? Comparing Match Outcomes and Developing a Predictive Model of Success Using Performance Metrics at the FIFA Club World Cup 2025

open access: yesApplied Sciences
In the present study, 96 teams’ performances across 48 matches in the group stage of the FIFA Club World Cup 2025 were analyzed. Teams scoring first won 62.5% of matches (p < 0.05), while goals were evenly distributed between halves (p > 0.05) and showed

Espresso coffees, caffeine and chlorogenic acid intake: potential health implications [PDF]

open access: yes, 2012
HPLC analysis of 20 commercial espresso coffees revealed 6-fold differences in caffeine levels, a 17-fold range of caffeoylquinic acid contents, and 4-fold differences in the caffeoylquinic acid:caffeine ratio.

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes

open access: yesAdvanced Functional Materials, EarlyView.
Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

THE HISTORY OF RESEARCH ON LATVIAN CUP-MARKED STONES

open access: yesCulture Crossroads, 2022
The stones known as cup-marked stones stand out among stones with marks of ancient artificial treatment in north-eastern Europe, as well as in the rest of the world. So far in the literature the view has predominated that the number of cup-marked stones in Latvia is small in comparison with neigh- bouring countries.
