Mylonite coal is a representative of tectonically deformed coal and is a result of crushing original coal into fine coal grains under strong shear or long‐low tectonic stress. Because of its granular nature and the resultant inferior mechanical property, it is difficult to initiate fluid‐driven fractures within mylonitic coal reservoirs for enhancing coalbed methane recovery. The following explores a biomineralization method of microbially mediated calcium carbonate precipitation (MICP) to enhance the structural integrity and mechanical strength of mylonitic coal, enabling potential success for hydrofracturing. The experimental results indicate that the mechanical properties of mylonite coal are significantly enhanced after a short period of MICP treatment with ten cycles of treatments yielding a maximum uniaxial compressive strength (UCS) of 8.7 MPa and a maximum brittleness index of 0.218 approaching that of the hard coal. The increments in UCS and brittleness of biocemented mylonite coal show a positive correlation with the generated calcium carbonate content. Scanning electron microscopy (SEM) imaging indicates that the generated calcium carbonate precipitates first randomly occur on the particle surfaces, and then occupies the interstitial space until particle‐particle bonds are developed. The irregular morphology of coal particles results in two contact relations between particles, point contact and planar contact, causing a significant difference in biocementation effectiveness. Two microfailure patterns of biocemented coal with uniaxial compression are observed. One is that the coal particles are crushed, and the other occurs at the biocemented interface between the coal particles and calcium carbonate crystals.

BACKGROUND: Sericin (SS) induces nucleation of bone-like hydroxyapatite (HAp) when used as an organic matrix. HAp/SS nanocomposites have been conventionally synthesized through precipitation in stirred tank reactors (STs). Despite its simplicity, this process is time consuming and presents difficulties in scale-up. In our study, HAp/SS nanocomposites were successfully synthesized in a ST and in a meso-oscillatory flow reactor (meso-OFR), to compare the efficiency of both reactors and to study HAp mineralization using SS as a template. RESULTS: The production of stable HAp, indicated by pH stabilization, was achieved after 180 min in the ST and after 30 min in the meso-OFR. X-ray diffraction and Fourier transform infrared analyses showed that the particles obtained in both reactors are HAp/SS nanocomposites with low crystallinity. Scanning electron microscopy evidenced the formation of rod-and plateshaped nanoparticles and revealed that the presence of SS led to the production of larger particles. The latter observation was confirmed by laser diffraction. Additionally, increasing SS concentration resulted in the formation of more plate-like particles. CONCLUSIONS: Precipitation is more efficient in the meso-OFR, HAp/SS being obtained four times faster. The presence and concentration of SS led to differences in the size and morphology of the synthesized particles, suggesting a critical role of SS in the mineralization process. This work reports a new approach for the manufacture of high-added-value nanocomposites with similar characteristics to biological bone and the results of a study of the influence of SS as an organic component in HAp nucleation. Further, the use of this protein and technology leads to significant waste minimization.

“…Additionally, chiral compounds have attracted significant attention in a variety of fields such as photonics, biosensing, catalysis, medicine, and nanotechnology. [18][19][20][21][22][23][24][25][26][27][28][29] For example, Williams et al 30 reported that a spiroborate with a chiral anion could be a promising candidate for chiral resolution. In addition, conducting chiral polymers such as polypyrrole (PPy), polythiophene (PTh), and polyaniline (PAn) have demonstrated promise in electrochemical chiral sensing and electrochemical asymmetric synthesis.…”

Solid polymer electrolytes (SPEs) with both excellent processability and flexibility have been deemed as an auspicious alternative to develop safe solid-state lithium metal (Li°) batteries (SSLMBs). The electrochemical performance of SSLMBs is ultimately associated with the nature of the Li-salt anion and the widely used bis(trifluoromethanesulfonyl)imide anion (TFSI) is "slippery" due to its perfluorinated nature and therefore highly mobile, which leads to severe polarization upon battery cell charge/discharge cycles. In this work, we report on a new type of chiral salts, synthesized from commercially available camphorsulfonic acid, used in poly(ethylene oxide) (PEO)-based SPEs. The impact of the chirality of the anions on the fundamental physical properties of the SPEs is extensively studied in terms of thermal stability, phase transition and ionic conductivity, etc. We demonstrate that the resulting SPEs exhibit agreeable ionic conductivities (ca. 10 -4 S cm -1 ) accompanied by high cation transference numbers (ca. 0.5) at 70 °C. Whether either the R or the S enantiomers are used the ion transport properties are the same, as expected, but rather surprisingly the artificial racemic mixture is within the errors of the measurements just as conductive. We discuss how this opens a new avenue to design novel salts for reaching high-performant SSLMBs.
