Journal of Experimental Orthopaedics, 2023 Purpose Robotic‐assisted total knee arthroplasty typically necessitates use of tracking pins, which can vary in diameter. Complications such as infections and fractures at the pin‐site have been observed, but clarification of the effect of pin diameter ...

Influence of pH and sequence in peptide aggregation via molecular simulation [PDF]
, 2015 We employ a recently developed coarse-grained model for peptides and proteins where the effect of pH is automatically included. We explore the effect of pH in the aggregation process of the amyloidogenic peptide KTVIIE and two related sequences, using three different pH environments. Simulations using large systems (24 peptides chains per box) allow us

Biosorption of Ag(I)-Spirulina platensis for different pH [PDF]
arXiv, 2011 Biosorption of Ag(I)-Spirulina platensis for different pH were investigated using dialysis and Atomic-absorbtion analysis. It was shown, that the biosorption constant for Ag(I) Spirulina platensis complex and the capacity depend on the change of pH. In particular, with the increase of pH (pH=5.5. and pH=8.6 cases), the biosorption constant increase and

pH-Sensitive Ultra-thin Oxide-Liquid Metal System: Understanding the Fundamental Sensing Mechanism [PDF]
arXiv, 2020 The pH response of liquid metal (eutectic GaInSn) in the form of a pendant drop is investigated and the sensitivity of 92.96 mV in the pH range from 4 to 10 is obtained. Unlike the fundamental limit of pH sensitivity of 59.1 mV in an electrolyte-site binding surface, the super-Nernstian pH sensitivity originated from a spontaneous electrochemical ...

Fabrication and characterization of pH responsive nanoprobes based on ion current rectification [PDF]
, 2018 In this study, we investigated the ionic current rectification of glass nanopipettes modified with bovine serum albumin - glutaraldehyde (BSA-GA) artificial membrane using solutions with various pHs. Ionic current rectification is a phenomenon that is observed with nanopores as asymmetric I-V curves, where the ionic currents recorded through a nanopore

The Beautiful Physics of LHC Run 2 [PDF]
arXiv, 2014 Run 2 of the LHC offers some beautiful prospects for new physics, including flavour physics as well as more detailed studies of the Higgs boson and searches for new physics beyond the Standard Model (BSM). One of the possibilities for BSM physics is supersymmetry, and flavour physics plays various important r\^oles in constraining supersymmetric models.

Two-photon polymerization of optical microresonators for precise pH sensing [PDF]
Light: Advanced Manufacturing (2024)5:54In water monitoring, environmental analysis, cell culture stability, and biomedical applications, precise pH control is demanded. Traditional methods like pH strips and meters have limitations: pH strips lack precision, while electrochemical meters, though more accurate, are fragile, prone to drift, and unsuitable for small volumes.
