Review on ultra-low cycle fatigue of metallic materials: performance, damage, and life evaluation

Journal of Materials Research and Technology
In the structural safety of construction, aerospace, and marine engineering, etc., the ultra-low cycle fatigue (ULCF) performance of metallic materials is critical.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Innovative spatial timber structures: workshops with physical modeling explorations from small to full scale [PDF]

, 2010
Architects and Engineers are educated and work within two separate cultures yet they are both concerned with conceptual structural design. The collaboration between the professions is especially important when designing buildings where the structure ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Tunable Metal–Organic Frameworks for Heat Transformation Applications

Nanomaterials, 2018
Metal–Organic Frameworks (MOFs) are a subclass of porous materials that have unique properties, such as varieties of structures from different metals and organic linkers and tunable porosity from a structure or framework design.

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

Molecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Exploring advanced materials

Trac-Trends in Analytical Chemistry
Inverse gas chromatography (IGC) has emerged as a highly sensitive, adaptable, and effective technology for material analysis. Through employing thermochemical approaches, IGC provides crucial insight into physicochemical information of materials such as dispersive surface free energy, Gibbs surface energy components and Guttamann Lewis acid-base ...

On Materials Imitating Materials: Exploring Historical Decorated Papers

Semiotika, 2023
Crossing the boundaries of any one discipline, the article provides an overview of research into historical decorated paper conducted by the author over the last several years. Examples of this seemingly very specific, ephemeral material, considered as an imitation of other materials, applied in bindings of printed books and manuscripts during the 18th
