Arsenite sorption and co-precipitation with calcite [PDF]
, 2006 Sorption of As(III) by calcite was investigated as a function of As(III) concentration, time and pH. The sorption isotherm, i.e. the log As(III) vs.

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 ...

Microrheology using dual beam optical tweezers and ultrasensitive force measurements [PDF]
, 2005 We investigate the dynamics of microscopic flow vortices. We create flow vortices by rotation of birefringent particles in optical tweezers. We then use either highly sensitive drag force measurements or video tracking to map the fluid velocity around ...

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.

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 ...

Vaterite Dissolution: Mechanism and Kinetics
The Journal of Physical Chemistry CThe 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 ...

Larnite powders and larnite/silica aerogel composites as effective agents for CO2 sequestration by carbonation [PDF]
, 2009 This paper presents the results of the carbonation reaction of two sample types: larnite (Ca2SiO4) powders and larnite/silica aerogel composites, the larnite acting as an active phase in a process of direct mineral carbonation.

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

Sub‐Micrometer Vaterite Containers: Synthesis, Substance Loading, and Release [PDF]
Angewandte Chemie, 2011 Promising candidates for the development of universal nanoscale delivery systems are porous inorganic nanoparticles. Recently, the applications of porous silicon in a multistage delivery system, in polymer coated nanocarriers, and of porous silica as core material for lipid bilayers have attracted great attention. A system with similarly high potential,
