Adhesive, Self-Healing, and Antibacterial Chitosan Hydrogels with Tunable Two-Layer Structures

Hydrogels with multifunctional properties such as biocompatibility, adhesion, and self-healing and inherent antibacterial properties are of great significance in biomedical applications, especially for wound dressings and drug release. However, it remains a significant challenge to combine all of these properties in a one-component hydrogel system. Furthermore, most injectable hydrogels are mechanically weak and not self-healing, which limits their applications as wound dressings. Herein, we designed a hydrogel with a tunable two-layer structure that endows the hydrogel with adhesion, self-healing, and antibacterial properties in different layers. First, chitosan (CHI) was oxidized to aldehyde-chitosan (ACHI). The Schiff base reaction was then used to fabricate the CHI/ACHI hydrogel resulting in the first layer. For the second layer, a physical cross-linking process using phytic acid (PA) as a sequential cross-linker was achieved, resulting in a CHI/ACHI/PA hydrogel. The CHI/ACHI hydrogel exhibited good injectable, adhesion, and self-healing properties. After cross-linking with PA, the CHI/ACHI/PA hydrogel showed enhanced mechanical properties, which enabled it to act as a protective layer. Additionally, the antibacterial test and cytotoxicity tests performed on this two-layer structured CHI/ACHI hydrogel exhibited excellent inherent antibacterial activity and good biocompatibility. The biocompatible injectable hydrogel was endowed with more possibilities relying on its self-healing and antibacterial abilities. These properties endorse the CHI/ACHI two-layer hydrogel as an excellent candidate for biological applications, especially wound dressings.

Estimation of Thermodynamic Properties and Phase Equilibria in Systems of Deep Eutectic Solvents by PC-SAFT EoS

This study examines the capabilities and shortcomings of perturbed-chain-statistical associating fluid theory equations of state (PC-SAFT EoS) applied for predicting properties and phase equilibria in systems of deep eutectic solvents. Treating deep eutectic solvents as pseudo-pure compounds and describing them as mixtures of two independent constituents are explored. Examples of choline chloride as the hydrogen bond acceptor (HBA) and levulinic acid, ethylene glycol, and phenol as hydrogen bond donors (HBDs) in a 1:2 molar ratio are considered. Excess properties of deep eutectic solvents with n-alkanols and water along with solubilities of carbon dioxide and ammonia are also considered. Besides that, liquid-liquid ternary systems of deep eutectic solvents with n-alkanes and 1-alkanols are analyzed. It has been found that although the pseudo-pure compounds approach with 2B associative scheme correctly estimates excess volumes, it exhibits poor accuracy in predicting excess enthalpies, solubility data, and liquid-liquid equilibria in ternary systems. When a temperature-dependent binary interaction between HBA and HBDs is applied, the individual approach predicts these properties in a more accurate manner.

An NIR-II light responsive antibacterial gelation for repetitious photothermal/thermodynamic synergistic therapy

Drug-resistant bacterial infection is a serious threat to the survival and health of human. Clinically, the conventional therapy for subcutaneous infections generally involves the systemic administration of high dose of antibiotics and frequently causes detrimental side effects in normal tissues. To overcome this issue, an acidity-responsive near infrared (NIR) light-triggered injectable hydrogel was designed for non-antibiotic local treatment. Herein, poly(ethylene glycol) diacrylate (PEGDA) was used as hydrogel matrix, polyoxometalate (POM) as acidity-enhanced photothermal agent and 2,2′-azobis[2-(2-imidazolin-2-yl) propane] dihydro-chloride (AIPH) as thermo-responsive initiator. After the hydrogel precursor solution (AIPH/POM/PEGDA) was injected into the acidic infected tissue, the aggregated POM with strong photothermal property was restricted to the site of abscess. Upon excitation at 1060 nm laser, the heat generated from POM would trigger alkyl radical formation from AIPH and thereafter achieving NIR-triggered in situ gel. Consequently, the POM and AIPH were trapped in Gel (AIPH/POM) and exhibited long-term retention in the abscess for further repeated local photothermal/thermodynamic antibacterial therapy. In vitro antibacterial evaluation indicated that the system could effectively eradicate drug-resistant bacteria through destroying bacteria integrity and producing the noxious alkyl radical under NIR light illumination. Moreover, the bacterial burden of abscess was significantly relieved and more collagens were deposited after the administration of Gel(AIPH/POM) and repeated NIR light. Meanwhile, no apparent adverse effect was observed during the treatment. This work not only provides a light-triggered gelation for local photothermal/thermodynamic synergistic therapy, but also offers a novel strategy for the rational design of light-responsive intelligent antibacterial hydrogels.

Kinetic modeling of dynamic changing active sites in a Mars-van Krevelen type reaction: Ethylene oxychlorination on K-doped CuCl2/Al2O3

A kinetic model was developed by taking into account the dynamic nature of the active sites in Mars-van Krevelen type catalytic reactions to predict the evolution of the reactant and product composition in the gas phase and the CuCl2 concentration in the solid catalyst. The kinetic model at the steady-state of ethylene oxychlorination was obtained by combining transient experiments of the two half-reactions in the redox cycle, namely CuCl2 reduced to Cud by ethylene and Cud oxidation by oxygen on the K-promoted CuCl2/gamma-Al2O3 catalyst. The dynamic transitions between CuCl2 and Cud of the active sites during the reactions are also modeled, and the contributions of two active sites, namely Cu coordination numbers of 4 and 3 in CuCl2 were distinguished and included in the kinetic model. The kinetic models describe well the transient response of the reduction and oxidation steps as well as the reaction at the steady-state at different reaction conditions. Moreover, by combining the reactor modeling through a steady-state approach, the spatial-time resolved CuCl2 profile and the C2H4 reaction rate can be well predicted in comparison with the experimental results. The approach of both transient and steady-state kinetic modeling and simulation is supposed to have general relevance for a better understanding of Mars-van Krevelen type reactions.

Microbial carbon use efficiency during plant residue decomposition: Integrating multi-enzyme stoichiometry and C balance approach

Accurate estimation of microbial carbon use efficiency (CUE) in soil is challenged by a high degree of genetic and environmental variability. Different methods vary in their estimates of soil microbial CUE giving the room to select the optimal method for a specific research task, while integrating different methods could improve our understanding of processes controlling CUE variability. Aiming to estimate CUE during plant residue decomposition in different soils, we applied the conventional C-balance method, single C-cycling enzymatic stoichiometry (SCE-STM) and newly proposed multi-C-cycling enzymatic stoichiometry (MCE-STM) methods. The STM approach derives CUE from elemental ratios of microbial biomass, substrate, and activities of C and nutrient (e.g. N) acquiring exoenzymes. The extended MCE-STM is a modification of the SCE-STM method, where we used the sum of three C-cycling enzymatic activities (beta-glucosidase (BGL), beta-D-cellobiohydrolase (BCL), beta-xylosidase (BXL)) as proxy for CUE calculation, instead of using a single C-acquiring enzyme (BGL). We hypothesized that MCE-STM provides a more reliable estimation of microbial CUE in soils amended with complex plant residues than the SCE-STM or the C balance approach. The comparison of methods was done in a laboratory incubation experiment, using two soils differing mainly in acidity level mixed with two specimen of plant residues differing in lignin (L) and polyphenol (PP) content. We anticipated a higher microbial CUE in less acidic (pH 5.1) soil amended with higher quality (lower (L + PP)/N) ratio)) plant residues than in more acidic (pH 4.3) soils amended with medium quality (higher (L + PP)/N ratio) plant residues, due to less energy investment in microbial metabolism in the former case. Microbial CUE estimations were completed at 7, 15, 30, 45 and 60 days. Lower CUE values (0.09-0.18) were recorded by MCE-STM as compare to those (0.24-0.47) obtained by C-balance and SCE-STM methods. Irrespective of applied CUE estimation methods, higher CUE was recorded in less acidic (pH 5.1) soil amended with residues of higher quality than the other three combinations. Microorganisms invested more energy to support growth in low pH soil in order to tolerate soil acidity, which, in turn, suppressed N-acquiring enzymatic activity and further decreased CUE. The modification of the MCE-STM method for CUE determination proposed in this work was capable to quantify the combined effect of soil pH and plant residue quality on efficiency of microbial metabolism. It, therefore, can be considered as viable alternative to the original stoichiometric modeling approach (SCE-STM).

Improvement of thermal energy accumulation by incorporation of carbon nanomaterial into magnesium chloride hexahydrate and magnesium nitrate hexahydrate

Magnesium chloride hexahydrate and magnesium nitrate hexahydrate were tested for their thermal energy storage in a mixture with carbon materials. The graphite, graphene and zeolite-templated carbon replicas were used as a nucleating agent to supress supercooling. The addition of any type of carbon into magnesium chloride hexahydrate did not lead to a decrease in the supercooling and a significant decrease of the enthalpy of fusion and crystallisation was observed. The mixtures after cycling were apparently wet, indicating that some of the magnesium chloride was dissolved in its structural water. In the case of magnesium nitrate hexahydrate, the addition of carbon replicas of zeolite beta, mordenite or faujasite lead to a decrease in supercooling. Nevertheless, graphite and graphene provided the highest supercooling suppression from about 30 to 2.2 K within the fifty cycles. The thermal conductivity measurement of pressed tablets of magnesium nitrate hexahydrate with carbon materials at 2 MPa showed a significant increase of 9% and 15% for the addition of 3 mass% of graphene and 3 mass% of graphite, respectively. Mixing of magnesium nitrate hexahydrate with graphene or graphite improved heat transfer and significantly reduced unwanted supercooling, which is necessary for its use in thermal energy accumulation.

Influence of nano-cementitious materials on improving the corrosion resistance and microstructure characteristics of concrete

Concrete is a building material widely used in construction due to its excellent mechanical properties such as compressive strength and bond strength with steel reinforcement. Strength and durability are the key factors that need to be satisfied in the design of reinforced concrete structures. The objective of this paper is to improve the bond strength and corrosion resistance of concrete by using supplementary nano cementitious materials such as Nano Metakaolin (NMK) and Nano Silica Fume (NSF). The addition of nano cementitious materials will help in enhancing the mechanical properties of concrete by improving the micro-structure. Effective bond between concrete and reinforcing steel ensures the load transformation among structural elements. The specimens are exposed to either chloride-induced acceleration-based corrosion test or chloride-induced immersion-based corrosion test. Investigations were conducted to evaluate the compressive strength, bond strength and corrosion resistance of concrete. Specimens with corrosion inhibitor/anti corrosive coating exhibited poor bond strength when compared to concrete with nano metakaolin and nano silica fume. The corrosion potential was found to be highly negative for control specimens. Specimens exposed to accelerated corrosion test exhibited lower bond strength with higher mass loss and low yield strength in the rebars. Extent of damage due to the effect of corrosion was analysed by physical observations and image analysis. Concrete with Nano Metakaolin exhibited better bond strength and corrosion resistance than those of the other specimens. Effect of nano Cementitious material on improving the micro-structure characteristics of concrete was confirmed by SEM. It was evident from the SEM results that, addition of NMK and NSF in concrete had a significant contribution in improving the bond strength and corrosion resistance.
