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

open access: yesDyna, 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.

Revealing growth increments in fossil and modern otoliths with backscattered electron imaging

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract Otoliths, the functional earstones of teleost fishes, record growth in the form of microscopic increments, making them key archives of individual life histories. While increment analysis is commonly applied to modern otoliths, studies of fossil (Holocene) otoliths remain limited.

Development of Protein‐Loaded Layer‐by‐Layer Capsules Using Mesoporous Silica Particle Templates

open access: yesParticle &Particle Systems Characterization, Volume 43, Issue 1, January 2026.
Porous silica particles are prepared by layer‐by‐layer (coating with oppositely charged polyelectrolytes. Capsules are obtained by selective removal of the silica template. Proteins and antibodies can be encapsulated by using this approach. The sensitive biomolecules retain their unique bioactivity in the process, and diffusion of small molecules into ...

Origin and distribution of mineral species in limestone caves [PDF]

open access: yes, 1971
More than 80 mineral species are known to result from secondary chemical reactions in solutional limestone caverns. These minerals are transitional and end-products of carbonate wall rock interactions with ground water and organic residue.
