Engineering Photonic Pigments From Titania–Block Copolymer Composites

open access: yesMacromolecular Rapid Communications, EarlyView.
Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.

Tailored for Binding: Alanine‐Modified Poly(1‐Naphthylamine) Targets Serum Albumins

open access: yesPolymer Engineering &Science, EarlyView.
Alanine modified poly(1‐naphthylamine). ABSTRACT This study presents a new approach for modifying the structural and functional properties of poly(1‐naphthylamine) (PNA) by incorporating the amino acid alanine (Ala) in different molar proportions (80/20, 50/50, and 20/80 for PNA/Ala) through an ultrasound‐assisted polymerization process.

Detailed analysis of iso-Pentanol combustion chemistry in flames [PDF]

open access: yes, 2013
In this study, two flames of iso-pentanol were stabilized on a 60-mm flat flame burner at a low pressure of 15 Torr and analyzed by a flame-sampling molecular-beam setup coupled to a mass spectrometer (MBMS).

Kerosene combustion in a supersonic flow

open access: yesJournal of Physics: Conference Series, 2019
Abstract A new approach is proposed to the initiation of kerosene combustion in a supersonic airflow with the stagnation temperature below 2000 K, which consists of a pulsed-periodic gas-dynamic action on the flow. The experiments have shown that it is possible to implement a quasi-steady pulsed combustion mode by choosing the parameters

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Automated Lawn Maintenance: An Agronomic and Operational Review of Turf Health, Biodiversity, and Field Performance

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Grass mowing is one of the most resource‐consuming activities in green maintenance, whether in private areas such as home gardens or in public spaces like urban parks. In recent years, concerns related to climate change, human health, and sustainability have become increasingly prominent in green maintenance, leading manufacturers and industry

Development and Validation of a Compressible Reacting Gas-Dynamic Flow Solver for Supersonic Combustion

open access: yesDynamics
An approach based on the OpenFOAM library has been developed to solve a high-speed, multicomponent mixture of a reacting, compressible flow. This work presents comprehensive validation of the newly developed solver, called compressibleCentralReactingFoam,
