Selective Benzene Capture by Metal‐Organic Frameworks
Advanced Functional Materials, EarlyView.Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.

Vertical Distributions of Some Trace Metals in Lake Nurume, Antarctica
Antarctic Record, 1977 The concentration of some trace metals (Fe, Mn, Cu, Zn, Pb, Cd) in Lake Nurume was measured vertically. The concentration of trace metals in surface water decreases with increasing depth to the intermediate water layer.

Biospheric traumas caused by large impacts and predicted relics in the sedimentary record [PDF]
When a large asteroid or comet impacts the Earth the supersonic plume ejected on impact causes severe shock heating and chemical reprocessing of the proximal atmosphere.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions
Advanced Functional Materials, EarlyView.This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Advanced Functional Materials, EarlyView.This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.

Fattori del suolo che influenzano la disponilità dei metalli per le piante [PDF]
, 1993 The knowledge of the interactions between metals and soil components is of great importance to evaluate the availability of the trace elements to plants as well as the potential danger of metals to soil and water beds.

Advanced Functional Materials, EarlyView.This work presents self‐propelled CRISPR/Cas9‐functionalized Au–MRs for rapid, amplification‐free, “on‐the‐fly” DNA detection. By harnessing motion‐assisted signal recovery, the platform achieved the limit of detection in low fM DNA concentrations, enabling detection across a wide dynamic range within only 5 min, which is significantly faster than any ...

The exploitation of nutrient metals by bacteria for survival and infection in the gut.
PLoS PathogensTrace transition metals are required for cellular life processes, such as respiration, metabolism, and DNA replication. At high levels, nutrient metals can be toxic due to oxidative stress and mismetallation of critical metalloenzymes.
