Carbonate- and silicate-metasomatized mantle beneath Himalayan-Tibetan orogenic belt

Communications Earth & Environment
The extreme geochemical enrichment of post-collisional potassium-rich lava in the Alpine-Himalayan orogenic belt has led researchers to hypothesize that enrichment is inherited from a metasomatized mantle source potentially incorporating crustal ...

Endophyte Inoculation and Elevated Potassium Supply on Productivity, Growth and Physiological Parameters of Spring Barley (Hordeum vulgare L.) Genotypes over Contrasting Seasons

Plants
In recent years, recurrent droughts have significantly affected spring barley production, reducing the quantity and quality of grain. This study aims to identify genotype-specific traits and the drought resilience of six different Hordeum vulgare L ...

Support‐Driven Hydrogen Migration Enhances Ammonia Decomposition in Direct Ammonia Protonic Ceramic Fuel Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Enhanced hydrogen species migration enabled by FN/BZY catalyst mitigates intermediate accumulation and improves DA‐PCFC performance during ammonia decomposition. Ammonia, with its high hydrogen density and carbon‐free nature, serves as ideal fuel for direct ammonia protonic ceramic fuel cells (DA‐PCFCs).

Rigid Ligand Environments at Beryllium, From Spectroscopic Probes to Small Molecule Activation

European Journal of Inorganic Chemistry, EarlyView.
Due to the high rigidity and definition of beryllium scorpionate complexes, they can be used to study metal‐pseudohalide and ‐carbon bonds in detail. Furthermore, these compounds can be used to activate small molecules and exhibit unprecedented transmetalation reactions. In beryllium scorpionate complexes, three of the four available coordination sites

Growth and Nitrogen Fixation in Silicon and/or Potassium Fed Chickpeas Grown under Drought and Well Watered Conditions [PDF]

Journal of Stress Physiology & Biochemistry, 2013
A pot experiment was conducted to study the effects of silicon (Si) and/or potassium (K) on plant growth, nitrogen uptake and N2-fixation in water stressed (FC1) and well watered (FC2) chickpea plants using 15N and 13C isotopes. Three fertilizer rates of

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

FlexMat, EarlyView.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

Geological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Streamlined Synthesis of Triamantane from Readily Available Starting Materials

Helvetica Chimica Acta, EarlyView.
A practical laboratory synthesis of triamantane based on the McKervey modification of the Schleyer stabilomeric synthesis is described. A high‐yielding rearrangement of Binor‐S and a significantly facilitated Diels–Alder step allowed an operationally simple sequence that reliably delivers triamantane on a tens‐of‐grams scale.
