Modeling Biocemented Sands: Hypoplastic Model for MICP‐Based Ground Improvement

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Bio‐cementation offers a sustainable and low‐carbon alternative to conventional ground improvement methods, aligning with the growing demand for green geotechnical solutions. To enable reliable numerical simulation of bio‐cemented soil behavior in engineering applications, advanced constitutive models are required to account for the effects of

Self‐Assembled Conjugated Hollow Fibers for Spongy Monoliths Toward Solar‐Driven Desalination and Hydrovoltaic Electricity Generation

Small, EarlyView.
A self‐assembled conjugated hollow fiber monolith enables simultaneous solar‐driven desalination and hydrovoltaic electricity generation. Metal‐free polymerization produces cross‐linked hollow fibers that entangle into a porous monolith, followed by gradient polypyrrole coating for efficient light absorption and directional water transport.

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

Natural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at

Fractional nonlocal strain-gradient isogeometric analysis of porous functionally graded piezoelectric microplates resting on elastic substrates

African Scientific Reports
Existing strain-gradient models for piezoelectric microplates often capture local microstructural size effects but do not simultaneously represent long-range spatial interactions, porosity-induced material degradation, electromechanical coupling, and ...

Comprehensive Analysis of Aluminum‐Substituted Lithium Nano Ferrites Using Experimental and DFT Approaches

International Journal of Quantum Chemistry, Volume 126, Issue 11, June 5, 2026.
The sol‐gel auto‐combustion‐fabricated Li0.5AlxFe2.5−xO4 nanoferrite with a single phase demonstrated soft magnetic characteristics. Significant changes in band gap and anisotropy were detected in the spin contributions of band structure and density of states, revealing lithium ferrites' potential for photovoltaic and spintronic applications.

Porosity-dependent vibration and dynamic stability of compositionally gradient nanofilms using nonlocal strain gradient theory

, 2017
Porosity-dependent free vibration and dynamic stability of functionally graded nanofilms are studied according to the nonlocal strain gradient theory. Two-scale coefficients are considered to incorporate both nonlocality and strain gradient impacts. The

Optical Pulling Force on Gold Mie Particles via Germanium and Aluminum‐Based Structures

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
This work demonstrates a novel approach to generate optical pulling force on gold Mie objects of two different shapes and studies the effects for different object sizes, incident angles, and the aluminum tetrahedra separation. Using rectangular germanium blocks combined with aluminum tetrahedra, optical pulling force (OPF) is achieved over a broad ...
