The Hemophore HasA from Yersinia pestis (HasAyp) Coordinates Hemin with a Single Residue, Tyr75, and with Minimal Conformational Change [PDF]

open access: yes, 2013
Hemophores from Serratia marcescens (HasAsm) and Pseudomonas aeruginosa (HasAp) bind hemin between two loops, which harbor the axial ligands H32 and Y75. Hemin binding to the Y75 loop triggers closing of the H32 loop and enables binding of H32.

Development of Electrohydraulic Forming Process for Aluminum Sheet with Sharp Edge

open access: yesAdvances in Materials Science and Engineering, 2017
Electrohydraulic forming (EHF), high-velocity forming technology, can improve the formability of a workpiece. Accordingly, this process can help engineers create products with sharper edges, allowing a product’s radius of curvature to be less than 2 mm ...

Mechanical properties of friction stir butt‐welded Al‐5086 H32 plate

open access: yesMaterialwissenschaft und Werkstofftechnik, 2009
AbstractAl‐5086 H32 plates with a thickness of 3 mm were friction stir butt‐welded using different welding speeds at a tool rotational speed of 1600 rpm. The effect of welding speed on the weld performance of the joints was investigated by conducting optical microscopy, microhardness measurements and mechanical tests (i.e. tensile and bend tests).

Biochemical and structural characterization of a tail‐spike protein with depolymerase activity identified in a marine podovirus

open access: yesActa Crystallographica Section D, Volume 82, Issue 7, Page 785-799, July 2026.
The marine tail‐spike protein Dpo31 degrades the exopolysaccharide of its host and has structural features similar to those of other members of this protein class, despite similarity not being detected at the sequence level.Marine phages are, through the infection of their bacterial hosts, key regulators of microbiome and carbon fluxes in the ocean ...

Analysis of Research Trends and Output Effectiveness in the Medical Field Based on the National Natural Science Foundation of China

open access: yesHealth Care Science, Volume 5, Issue 3, Page 231-239, June 2026.
The completion and output of NSFC‐funded medical projects reflect national strategic orientations and disciplinary development laws. It is suggested to establish a dynamic evaluation mechanism, promote the “basic research‐application‐transformation” collaborative model, support small‐scale yet high‐efficiency fields, and conduct long‐term tracking of ...
