Polymer-assisted enzyme induced carbonate precipitation for non-ammonia emission soil stabilization

Zhen Yan et al.

Summary: This paper presents a novel approach using polyacrylic acid (PAA) to prevent the formation of gaseous ammonia byproducts in the enzyme induced carbonate precipitation (EICP) process. By adjusting the pH to acidic, PAA enhances enzyme activity and prevents the release of ammonia, thus protecting the environment. Experimental results demonstrate the great potential of PAA for large-scale promotion of biocement.

Aerodynamics Effect of Holes in UAV Wings Modified for VTOL Capability

Laith S. Sawaqed et al.

Summary: This research explores the possibility of modifying the X8 Skywalker from a fixed-wing unmanned aerial vehicle into a convertiplane. Computational fluid dynamics and wind tunnel experiments were conducted to analyze the performance of different wing configurations. The results indicate that the proposed modifications can generate enough lift despite reducing the wing area, with the filleted hole configuration demonstrating less drag and turbulence effects at low angles of attack.

Role of Protein in Fungal Biomineralization of Copper Carbonate Nanoparticles

Feixue Liu et al.

Summary: Biomineralization processes play a crucial role in the biogeochemical cycling of metals by microorganisms, with potential applications in nanoparticle synthesis. This study elucidated the association of fungal proteins in the formation of biogenic copper carbonate nanoparticles, particularly identifying triosephosphate isomerase (TPI) as a key protein involved in shaping nanomaterial morphology. The research also highlighted the unfolding of proteins and increased beta sheets within protein structures during biomineralization, providing insights into the mechanisms involved in the formation of complex protein/inorganic systems for nanomaterial synthesis.

Mechanism of carbonate mineralization induced by microbes: Taking Curvibacter lanceolatus strain HJ-1 as an example

Guoguo Yang et al.

Summary: Microbial-induced carbonate precipitation is facilitated by Curvibacter lanceolatus strain HJ-1, extracellular polymeric substances (EPS), and carbonic anhydrase (CA). The presence of CA in EPS contributes to CO2 hydration and eventually leads to carbonate precipitation, particularly favoring aragonite formation. Additionally, HJ-1 and EPS act as nucleation sites for calcite and aragonite formation.

Calcium phosphate biocement using bone meal and acid urease: An eco-friendly approach for soil improvement

Sivakumar Gowthaman et al.

Summary: Biocementation technology is a new soil improvement method which involves the enzymatic formation of calcium carbonate or calcium phosphate. Compared to conventional methods, calcium phosphate biocementation can control the release of ammonium ions and gaseous ammonia at different pH ranges, while improving the soil's compressive strength.

Reduction of ammonia production in the biocementation process for sand using a new biocement

Xiaoniu Yu et al.

Summary: A new biocementation method using a microbially-induced struvite precipitation process is proposed to reduce ammonia discharge and improve the unconfined compressive strength of sand. The main cementation components produced by this method are struvite and basic magnesium phosphate, leading to a significant reduction in ammonia emissions by over 8 times.

Tuning Polymorphs and Morphology of Microbially Induced Calcium Carbonate: Controlling Factors and Underlying Mechanisms

Maryam Khanjani et al.

Summary: This study investigates how bacterial activity, solution chemistry, and precipitation kinetics influence the polymorphism and morphology of microbially precipitated calcium carbonate induced by Sporosarcina pasteurii. The results show that in the presence of sufficient calcium ions and urea, vaterite formation is favored. Morphological observations reveal important information on particle microstructure, with calcite evolving from single crystal to polycrystalline structures and vaterite evolving from spherical to oval-shaped structures. Specific functional groups exert control on the morphology of CaCO3 polymorphs, with calcite being more sensitive to these groups compared to vaterite.

Bio-mineralisation, characterization, and stability of calcium carbonate containing organic matter

Renlu Liu et al.

Summary: This study elucidates the bio-mineralisation and stability of amorphous calcium carbonate and vaterite containing organic matter induced by Bacillus subtilis. The bacteria can induce various structural forms of CaCO3 using bacterial cells as templates. Results show that Ca2+ concentration affects the crystal structure of CaCO3, and organic matter plays a crucial role in the stability of biogenic ACC and vaterite. Our findings provide valuable insights for future research on organic-CaCO3 complexes.
