Insights Into the Mechanisms Controlling the Residual Strength of Bio‐cemented Sands

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 6, Page 2711-2726, 25 April 2026.
ABSTRACT Microbially induced carbonate precipitation (MICP) is an emerging technique for enhancing the mechanical properties of granular soils. Although several experimental studies have reported increased shear strength in MICP‐treated soils at both peak and residual states, other findings have shown reductions in residual strength compared to ...

Vaterite Dissolution: Mechanism and Kinetics

The Journal of Physical Chemistry C
The dissolution of porous spherulitic, vaterite particles in aqueous solution is investigated via microscopic monitoring of their size as a function of time. The latter is shown to provide a clear, generic distinction between dissolution controlled either by the rate of a surface-controlled reaction or via dissolution under conditions where the ...

Harvesting the Spin–Orbit Interaction of Light to Generate Helicity‐Dependent Complex Rotational Motion in Optically Trapped Mesoscopic Matter

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
Spin–orbit interaction (SOI) of light is exploited to generate helicity‐dependent complex rotational and revolution dynamics in optical tweezers. At the trap center, particle rotation is governed by the direct helicity that follows the input polarization.

Effect of the tryptone concentration on the calcium carbonate biomineralization mediated by Bacillus cereus

Dyna, 2018
Five tryptone concentrations (0.2%, 0.4%, 0.6%, 0.8% and 1.0%) were evaluated on calcium carbonate biomineralization processes, using 0.5% of calcium acetate.

Bio‐Inspired Nanoarchitected LiFePO4 Cathodes

Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.
Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...

Integrating Direct Air Capture Technology and Plasma Based Calcination for Sustainable Syngas and Concrete – An Experimental Investigation

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.
This study presents an experimental Proof‐of‐Concept of an electrified CO2${\rm CO}_2$ loop that combines DAC and GA‐plasma conversion. Atmospheric CO2${\rm CO}_2$ is captured and solidified as CaCO3${\rm CaCO}_3$, followed by plasma‐based calcination to regenerate CaO and with the possibility to split CO2${\rm CO}_2$ into CO for syngas synthesis. This

Confinement stabilises single crystal vaterite rods

Chem. Commun., 2014
Single-crystals of vaterite, the least-stable anhydrous polymorph of CaCO 3 , are rare in biogenic and synthetic systems. We here describe the synthesis of high aspect ratio single crystal vaterite rods under additive-free conditions by precipitating CaCO 3

Influence of Selected Saccharides on the Precipitation of Calcium-Vaterite Mixtures by the CO₂ Bubbling Method

Crystals, 2019
Calcium carbonate is a compound existing in living organisms and produced for many biomedical applications. In this work, calcium carbonate was synthesized by a CO2 bubbling method using ammonia as a CO2 absorption promotor.
