Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

From the Fibonacci Icosagrid to E₈ (Part II): The Composite Mapping of the Cores

Crystals
This paper is part of a series that describes the Fibonacci icosagrid quasicrystal (FIG) and its relation to the E8 root lattice. The FIG was originally constructed to represent the intersection points of an icosahedrally symmetric collection of planar ...

Coherent States for Fractional Powers of the Harmonic Oscillator Hamiltonian

Universe, 2021
Inspired by special and general relativistic systems that can have Hamiltonians involving square roots or more general fractional powers, in this article, we address the question of how a suitable set of coherent states for such systems can be obtained ...

Surfactants as a Tool for Coupling Light Into Hydrodynamic Flow: The Influence of Surfactant Hydrophobicity and Head Polarity

Advanced Materials Interfaces, EarlyView.
Reversible light‐induced gradients at solid–liquid interfaces enable controllable interfacial transport via light‐driven diffusioosmosis. We demonstrate directed particle manipulation based on dynamically generated concentration gradients. The mechanism is broadly applicable to cationic, anionic, and non‐ionic surfactants with varying hydrophobicity ...

Quantum gravity: a hypothesis

Europhysics Letters (EPL), 1992
Erratum for Europhys. Lett., 17 (1), pp. 1-4 (1992) On the bottom of page 2, one should replace ρ = p by ρ = − p. As a result the vacuum energy density ρ around matter is increased (not lowered as was mentioned on page 3). The corrected equations were applied in [1].

Visions in quantum gravity [PDF]

SciPost Physics Community Reports
To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is crucial. The Nordita Program “Quantum Gravity: From gravitational effective field theories to ultraviolet complete approaches” created a platform for extensive discussions ...

Evolution of OLED Lamination Technology With Development of Display Form Factors

Advanced Materials Technologies, EarlyView.
This review evaluates the evolution of organic light‐emitting diode (OLED) lamination technologies alongside advancing display form factors. It contrasts optically clear adhesives and resins, highlighting uniformity control for rigid screens, bubble‐free optimization for bended architectures, and visible‐light curing for foldable layers.

Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Toward the Unification of Physics and Number Theory [PDF]

Reports in Advances of Physical Sciences, 2019
This paper introduces the notion of simplex-integers and shows how, in contrast to digital numbers, they are the most powerful numerical symbols that implicitly express the information of an integer and its set theoretic substructure.

RESUMMED QUANTUM GRAVITY

International Journal of Modern Physics D, 2007
We present the current status of the new approach to quantum general relativity based on the exact resummation of its perturbative series as this series was formulated by Feynman. We show that the resummed theory is UV-finite and we present some phenomenological applications as well.
