• Consideration of Pseudo Strain Energy in Determination of Fatigue Life and Microdamage Healing of Asphalt Mastics

  Publikacja

  • D. Ryś
  • C. Szydłowski

  - INTERNATIONAL JOURNAL OF FATIGUE - Rok 2024

  Rest periods between cyclic loads can lead to recovery of damage and extension of fatigue life. This phenomenon is referred to as healing. Healing is clearly observed in bituminous materials, such as asphalt mastics, which belong to the components of asphalt mixtures. Due to the nature of road pavement traffic loading, which is characterized by series of intermittent pulses with rest periods, consideration of healing is necessary...

• Mechanochemical Energy Transduction during the Main Rotary Step in the Synthesis Cycle of F1-ATPase

  Publikacja

  • J. Czub
  • M. Wieczór
  • B. Prokopowicz
  • H. Grubmüller

  - JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Rok 2017

  F1-ATPase is a highly efficient molecular motor that can synthesize ATP driven by a mechanical torque. Its ability to function reversibly in either direction requires tight mechanochemical coupling between the catalytic domain and the rotating central shaft, as well as temporal control of substrate binding and product release. Despite great efforts and significant progress, the molecular details of this synchronized and fine-tuned...

  Carnivorous plants are exemplary natural sources of secondary metabolites with biological activity. However, the therapeutic antimicrobial potential of these compounds is limited due to intrinsic resistance of selected bacterial pathogens, among which Pseudomonas aeruginosa represents an extreme example. The objective of the study was to overcome the intrinsic resistance of P. aeruginosa by combining silver nanoparticles (AgNPs)...

• An Ultra-Low-Energy Analog Comparator for A/D Converters in CMOS Image Sensors

  Publikacja

  • W. Jendernalik

  - CIRCUITS SYSTEMS AND SIGNAL PROCESSING - Rok 2017

  This paper proposes a new solution of an ultra-low-energy analog comparator, dedicated to slope analog-to-digital converters (ADC), particularly suited for CMOS image sensors (CISs) featuring a large number of ADCs. For massively parallel imaging arrays, this number may be as high as tens-hundreds of thousands ADCs. As each ADC includes an analog comparator, the number of these comparators in CIS is always high. Detailed analysis...

  Publikacja

  • S. Winczewski
  • J. Dziedzic
  • J. Rybicki

  - MODELLING AND SIMULATION IN MATERIALS SCIENCE AND ENGINEERING - Rok 2016

  Central-force decompositions are fundamental to the calculation of stress fields in atomic systems by means of Hardy stress. We derive expressions for a central-force decomposition of the spline-based modified embedded atom method (s-MEAM) potential. The expressions are subsequently simplified to a form that can be readily used in molecular-dynamics simulations, enabling the calculation of the spatial distribution of stress in...

• Accurate and continuous adhesive fracture energy determination using an instrumented wedge test

  Publikacja

  • M. Budzik
  • J. Jumel
  • K. Imielińska
  • M. Shanahan

  - INTERNATIONAL JOURNAL OF ADHESION AND ADHESIVES - Rok 2009

  The wedge test and the related double cantilever beam test are practical methods of assessing structural adhesive fracture energy. In the former, and to a lesser extent the latter, a recognised problem is the difficulty of following the length of the growing crack, required to calculate fracture energy with any accuracy. We present a novel method of measurement of crack length that has the advantages of being accurate and allowing...

• Cleaner energy for sustainable future using hybrid photovoltaics-thermoelectric generators system under non-static conditions using machine learning based control technique

  Publikacja

  • A. Mirza
  • P. Szczepankowski
  • J. Łuszcz

  - Sustainable Energy Technologies and Assessments - Rok 2022

  In addition to the load demand, the temperature difference between the hot and cold sides of the thermoelectric generator (TEG) module determines the output power for thermoelectric generator systems. Maximum power point tracking (MPPT) control is needed to track the optimal global power point as operating conditions change. The growing use of electricity and the decline in the use of fossil fuels have sparked interest in photovoltaic-TEG...

  • P. Jasiński

  - MEASUREMENT SCIENCE & TECHNOLOGY - Rok 2017

  In this work, a new approach for using a 3D polypyrrole (PPy) conducting polymer as a sensing material for glucose detection is proposed. Polypyrrole is electrochemically polymerized on a platinum screen-printed electrode in an aqueous solution of lithium perchlorate and pyrrole. PPy exhibits a high electroactive surface area and high electrochemical stability, which results in it having excellent electrocatalytic properties. The...
