Coral reef limestone at different depositional depths and facies differ remarkably on the textural mineralogical characteristics, owing to complex sedimentary diagenesis. To explore effects of pore structure mineral composition associated with diagenetic variation mechanical behavior limestone, a series quasi-static dynamic compression tests along microscopic examinations were performed shallow deep burial depths. It is revealed that (SRL) classified as porous aragonite-type carbonate rock...
The linear-infrared and two-dimensional infrared (2D IR) spectra in the amide-I' region of alanine dipeptide its 13C isotopomers aqueous solution (D2O) are reported. two IR transitions have been assigned unambiguously by using isotopic substitution carbonyl group; amide unit at acetyl end shows a lower transition frequency unlabeled species. ratio their dipole strengths remains almost unchanged upon substitution, indicating absence intensity transfer between vibrators. 2D cross peaks...
With the increasing demand for higher gene carrier performance, a multifunctional vector could immensely simplify delivery disease treatment; nevertheless, current non- viral vectors lack self-tracking ability. Here, type of novel, dual-functional cationic carbon dots (CDs), produced through one-step, microwave-assisted pyrolysis arginine and glucose, have been utilized as both self-imaging agent non-viral chondrogenesis from fibroblasts. The CDs condense model plasmid SOX9 (pSOX9) to form...
Graphene oxide has widely been employed in various fields, but its structure and composition still not fully understood. Here we report that freshly prepared graphene exhibits a large number of π-conjugated carbon radicals at π-network plane, which result from the addition reaction hydroxyl H2O2 onto conjugated double bonds oxide. The can directly initiate long-lasting visible chemiluminescence luminol, is even stronger than obtained when horseradish peroxidase are used. Previously, was...
An electronic nose can detect highly volatile chemicals in foods, drugs, and environments, but it is still very much a challenge to the odors from crystalline compounds (e.g., solid explosives) with low vapor pressure using present chemosensing techniques such way as dog's olfactory system do. Here, we inkjet printed silver nanoparticles (AgNPs) on cellulose paper established Raman spectroscopic approach of explosive trinitrotoluene (TNT) crystals residues open environment. The...
Superstretchable materials have many applications in advanced technological fields but are difficult to stretch more than 1000× their original length. A superstretchable dynamic polymer network that can be stretched 13 000× its length is designed. It revealed superstretchability of the derived from synergistic effect two different types bonds, including a small number strong imine bonds maintain integrity during stretching and large weak ionic hydrogen dissipate energy. This approach...
This paper concerns a higher-dimensional Keller-Segel model with signal-dependent motility and logistic growth. It is shown that the strong damping can prevent blow-up in higher dimensions.
Establishing a direct correlation between interfacial water and heterogeneous ice nucleation (HIN) is essential for understanding the mechanism of nucleation. Here, we study HIN efficiency on polyvinyl alcohol (PVA) surfaces with different densities hydroxyl groups. We find that increases decreasing group density. By explicitly considering molecules PVA films consist "tightly bound water," "bound "bulk-like reveal bulk-like can be correlated directly to surfaces. As density groups decreases,...

Osteoporosis is a systemic skeletal disease caused by an imbalance between bone resorption and formation. Current treatments primarily involve medication hormone therapy. However, these lack directionality are often ineffective for locally severe osteoporosis, with the potential complex adverse reactions. Consequently, treatment strategies using bioactive materials or external interventions have emerged as most promising approaches. This review proposes twelve microenvironmental targets...
