Residual stress and distortion analysis of laser powder bed additive manufactured parts using the incremental hole drilling method and the cantilever method

open access: yesJournal of Advanced Joining Processes
This study investigates residual stresses and distortion in additively manufactured 316L austenitic steel and M350 martensitic high strength steel produced by laser powder bed fusion under varying process parameters.

Very High Cycle Fatigue Behavior of TA11 Titanium Alloy

open access: yesJournal of Aeronautical Materials, 2017
The conventional fatigue test method was used to obtain the very high cycle fatigue (VHCF) limits of 3×107 and 1×108 cycles for TA11 titanium alloy in different temperatures and stress ratios.

Hulk Smash”™ Busting the OAA Silo! [PDF]

open access: yes, 2015
This poster focuses on Lavery Library’s collaboration with the Office of Academic Affairs, OAA. At St. John Fisher College students with learning disabilities testing accommodations take their exams in the library instead of a testing center.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

open access: yesFEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

Testing of typical spacecraft materials in a simulated substorm environment [PDF]

open access: yes, 1977
The test specimens were spacecraft paints, silvered Teflon, thermal blankets, and solar array segments. The samples, ranging in size from 300 to 1000 sq cm were exposed to monoenergetic electron energies from 2 to 20 keV at a current density of 1 NA/sq ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Bond line shear strength of structural wood adhesives at high temperatures up to wood carbonization – A classification approach

open access: yesResults in Engineering
The European timber fire design code EN 1995-1-2 presently specifies that adhesives for timber construction products shall provide integrity throughout the intended fire exposure time, yet no test or requirement specifications are given.

Squaraine Planar-Heterojunction Solar Cells

open access: yesInternational Journal of Photoenergy, 2009
The photovoltaic performance of squaraine-based organic solar cells is investigated. Two squaraine derivatives with extraordinarily high extinction coefficients are used as electron donors in bilayer heterojunctions with fullerene C60 as electron ...

Friction and Wear Behaviour of Graphite Filled Polymer Composites in Hydrogen Environment

open access: yesTribology Online, 2015
High performance polymer composites have been intensively investigated for tribological applications in air, but rarely in hydrogen environment. Author’s previous benchmark of composites in liquid hydrogen (LH2) showed that graphite filled polymers have ...
