Antimicrobial Titanium–Copper Alloys: The Role of Microstructure in Arc‐Melted Compositions

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐containing titanium alloys show promise in combating orthopedic implant infections. This study explores the influence of heat treatment on Ti‐11.5Cu and Ti‐33Cu alloys, revealing that larger Ti2Cu precipitates (≈5 μm) enhance antimicrobial efficacy through increased surface contact. Results suggest contact sterilization is the primary mechanism,

Predicting Proton-Air Cross Sections at sqrt s ~30 TeV, using Accelerator and Cosmic Ray Data

open access: yes, 1999
We use the high energy predictions of a QCD-inspired parameterization of all accelerator data on forward proton-proton and antiproton-proton scattering amplitudes, along with Glauber theory, to predict proton-air cross sections at energies near \sqrt s ...

The leading proton effect in proton-proton collisions

open access: yesNuclear Physics B, 1973
Abstract The p spectrum data in the range s = 28 to s = 1995 are described with the triple Regge formula. The behaviour of the various couplings at small | t | is explored. It is found that the non-scaling terms, at s ≅ 400 GeV 2 remove the turnover expected if the triple pomeron vanishes at t = 0.

Poly(1,4‐anthraquinone) as an Organic Electrode Material: Interplay of the Electronic and Structural Properties due to the Unusual Lone‐Pair‐π Conjugation

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
In this study, the unique role of the unusual lone‐pair‐π conjugation mechanism in poly(1,4‐anthraquinone) (P14AQ) is explored as an organic electrode material. Unlike traditional π‐π interactions, P14AQ's conjugation involves lone pairs of oxygen atoms interacting with the π cloud of adjacent units, enabling stable charge transport even with minimal π‐

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

open access: yesAdvanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Improving total bone marrow and lymphoid irradiation: feasibility of intensity-modulated proton therapy (IMPT) and dosimetric comparison with helical tomotherapy (HT)

open access: yesRadiation Oncology
Background and purpose This study aims to develop and validate a novel whole-body intensity-modulated proton therapy (IMPT) approach for total marrow/lymphatic irradiation (TMI/TMLI) and compare its efficacy to helical tomotherapy (HT).

The Energy-Dependent Black-Disk Fraction in Proton-Proton Scattering

open access: yes, 2018
Recent work by Block et al on the energy-invariant edge in proton-proton scattering is interpreted by quantitatively introducing a energy-dependent black-disk fraction of the proton-proton interaction.Comment: 7 pages, expanded version, including impact ...
