Wearable electronic skins capable of overcoming sweat interference and leveraging sweat biomarkers are crucial for clinical-grade monitoring. Here, we report a holistic hydration-triggered whole-body E-Skin (HTWB-E-Skin) constructed from a biocompatible composite of nanofibrous silk fibroin and silver nanowires (Ag NWs). The elegance of this design lies in its structurally simple, multifunctional architecture, which leverages the hydration-triggered mechanism to synergistically enhance both biomechanical and biochemical sensing. On one hand, the design leverages silk's hydration-triggered conformational transition, as confirmed by theoretical and experimental studies, to achieve rapid sweat absorption (<10 s), exceptional water retention (>600% mass increase), and stable adhesion on wet skin. On the other hand, the embedded Ag NWs with silk fibroin concurrently enable motion-robust electrocardiogram (ECG) monitoring and generate plasmonic hotspots for surface-enhanced Raman spectroscopy (SERS). Through passive capillary action, trace sweat is autonomously channeled to sensing zones, enabling label-free, real-time continuous metabolic dynamics analysis of clinically relevant biomarkers (e.g., uric acid and urea) at ultralow concentrations, facilitating personalized nutritional oversight and health management. Integrated with a portable 12-lead Cloud-ECG module, the platform supports motion-adaptive ECG, speech recognition, and whole-body motion sensing, outperforming commercial electrodes, offering a practical methodology for long-term personalized health monitoring and point-of-care diagnostics.

A silk inspired triple hydrogen bonding gelator, NASA with multiple functional groups was synthesized. • PNASA supramolecular coating showed strong antifouling abilities. • A triple hydrogen-bond engineered hydration layer was formed on the PNASA coating surface. Hydration layer formed by strong hydrogen bonding is an alternative candidate strategy for antifouling coating used for implanted biomedical device. Inspired from the high serine content and low immune reaction of silk, N-Acryloyl serinamide (NASA) was successful synthesized to prepare triple hydrogen-bonded-engineered poly(N-Acryloyl serinamide) (PNASA) supramolecular coating. The chemical structure of NASA showed active triple hydrogen bond sites that easily bonded with itself, water, and other molecules. Therefore, PNASA supramolecular coating was self-assembly formed by chain entanglement and hydrogen bond, and the crosslinking network was filled with triple hydrogen bonding domains. The results revealed PNASA supramolecular coating was endowed with tunable hydrophilicity and superior antibiofouling due to the strong surface hydration abilities, which resisted non-specific protein adsorption, platelets adhesion, bacterial and cell attachment effectively. Additionally, the low hemolysis and high viability proved the good biocompatibility of PNASA supramolecular coating. Therefore, PNASA supramolecular coating shows great potential in biomedicine containing tissue engineering, implanted biomedical devices, and organoids.

Sodium gluconate (SG) is a commonly used concrete retarder, but its impact on the hydration of tricalcium aluminate (C3A) is not fully understood. This study investigates the effects of SG on the hydration products of the C3A-gypsum system, including ettringite (AFt), monosulfate (AFm), and hydrogarnet (C3AH6), by isothermal calorimetry, XRD, TG-DSC, ICP analysis, and thermodynamic modeling. Results reveal that there is no concentration threshold for the inhibitory effect of SG on C3A hydration. SG concentrations of 0.2% to 1% inhibit the formation of AFt, AFm, and C3AH6 to varying degrees, with higher SG concentrations resulting in greater inhibition. The inhibitory effect is attributed to SG adsorption on C3A and hindrance of gypsum dissolution. These findings contribute to the understanding of admixture interactions in cement and offer guidance for concrete additive development.

Although methane-dense storage is anticipated in wet nanoporous materials using the synergy of adsorption and hydration (the so-called adsorption–hydration natural gas, AHNG), the understanding of this technology is still insufficient, which limits its large-scale application. Here, new insights into the AHNG technology are presented, including new findings, phenomena, problems, and solutions, which are helpful to improve the understanding of this technology, enhance methane storage density, and pave the way for its application. Both synergy and antagonism between adsorption and hydration were observed; the synergy increases methane storage capacity, while the antagonism weakens the adsorption and hydration efficiency. In addition, two special phenomena were discussed, which have never been noticed by the hydrate community, and artificial intelligence was thought to provide an effective method for material design, while a storage cell was suggested to improve inner mass transfer of AHNG storage tanks.

Molten salt hydrates (MSH) are efficient, environmentally friendly solvents widely used in polysaccharide dissolution and catalysis. This study thus exquisitely designed a series of acidic ZnCl 2 ·nH 2 O MSH systems with different hydration levels, and investigate their effect toward the selective fractionation of wheat straw components. With the increase in the hydration level of the acidic ZnCl 2 .nH 2 O MSH system, the hemicellulose removal rate gradually decreases, while cellulose retention improves. Among all, the ZnCl 2 ·6H 2 O system, under optimal conditions (5 % sulfuric acid, 100 °C for 20 min), achieved the best performance with 90.34 % cellulose retention, 93.32 % hemicellulose removal, and 34.07 % lignin removal, resulting in 80.55 % enzymatic digestibility of cellulose. The dissolution mechanism of hemicellulose in the acidic ZnCl 2 ·6H 2 O system was then elucidated by the computational simulations, where the results indicate that hemicellulose molecular chains exhibit greater extension and stability within the ZnCl 2 ·6H 2 O system, accompanied by stronger non-bonded interactions and a more uniform distribution of ions and water molecules. These factors enhance the interaction between the solvent and hemicellulose molecules, leading to higher solubilization efficiency. Further calculations revealed that hemicellulose has the strongest interaction energy with the ZnCl 2 ·6H 2 O/H 2 SO 4 system, confirming its superior selectivity for hemicellulose removal.

Swelling of clay minerals is one of the main factors restricting the efficient exploration and development of shale oil and gas. To solve this issue, the free radical induction method was employed to synthesize a polymer grafted with dopamine derivatives, P(AM-DA). This study aimed to evaluate the inhibitory properties of P(AM-DA) on the hydration and swelling of clay and analyze its mechanism. Firstly, P(AM-DA) was characterized by FTIR, HNMR, and TGA. Subsequently, anti-swelling, anti-disintegration, and immersion tests were conducted to evaluate its inhibitory properties. Then, the inhibitory mechanism was further elucidated through Zeta potential tests, particle size analysis, XRD tests, and SEM analysis. Finally, the properties of P(AM-DA) on mud rheology and fluid loss were evaluated. The experimental results showed that the dopamine derivatives were successfully grafted onto the polymer's side chains. Additionally, the result of TGA demonstrated the polymer's good thermal stability below 200℃. P(AM-DA) showed a superior inhibitory effect, and the swelling rate of cores was much lower than that of KCl and polyetheramine. Despite the clay mineral content of shale cuttings being as high as 51.1 %, the anti-disintegration rate could be increased by 66.45 %. The Na-BT core retained its shape and structural integrity after 72-hours immersion, and it could support a weight of 200 g. Regarding the inhibitory mechanism, P(AM-DA) could adsorb onto the surface of clay particles through hydrogen bonding and electrostatic interaction, which reduced the dispersion of clay particles. The protonated amine groups could neutralize the electronegativity of the clay particles, reducing the electrostatic repulsion between the layers. Besides, P(AM-DA) exhibited a series of special behaviors, such as adsorption on the core surface to form a homogeneous layer and insertion into the crystal layer of clay. Both of these behaviors could decrease the passage of water molecules, and the intercalation behavior could also reduce and stabilize the interlayer spacing. In addition, P(AM-DA) could dramatically increase the viscosity of the fluid at higher concentrations and unexpectedly reduce fluid loss. In conclusion, P(AM-DA) showed considerable promise in inhibiting hydration and swelling of clay.

Belite-Ye’elimite-Ternesite (BYT) clinker has many advantages compared to Portland cement (PC) clinker, including low sintering temperature and low carbon emission. In this study, we systematically investigated the hydration reaction of BYT clinker in the present of gypsum (CaSO 4 ·2 H 2 O) and compared the properties of BYT clinker with different gypsum additions. The results showed that the gypsum additions of 5 % and 10 % promoted the early exothermic reaction of BYT clinker. In the hydration process of BYT clinker, an inhibitory effect of gypsum was found on the hydration of belite. In addition, the mechanism for the influence of gypsum additions on the hydration behavior of BYT clinker was illustrated that when the content of gypsum was more than 15 %, the production of AFm (C 6 A$H 12 ) and strätlingite (C 2 ASH 8 ) was limited due to the massive formation of AFt (C 6 A$ 3 H 32 ). The addition of gypsum improved pore size distribution and compressive strength. Especially, the 1-day and 56-day compressive strength of BYT clinker increased by 41.6 % and 47.4 %, with gypsum additions of 5 % and 20 %, respectively.

Frequent wellbore instability issues caused by shale hydration and dispersion are encountered in water-based drilling fluids. In order to mitigate shale hydration, a hydrophobic graphene oxide (HGO) was prepared as a new shale inhibitor and characterized. The effectiveness of HGO in inhibiting shale hydration was evaluated through hydration expansion, hydration dispersion, and bentonite sheets immersion tests. The expansion height of bentonite in HGO (3.87 mm) was lower than that of commercial shale inhibitors potassium chloride (KCl, 4.64 mm) and polyether amine (PA, 4.33 mm). The shale recovery rate in HGO at 80 °C was 86.25 %, which was superior to KCl (46.60 %) and PA (78.25 %). Furthermore, the morphology of bentonite sheet remained more intact after immersion in HGO. Additionally, the inhibitory mechanism of HGO was studied in-depth, employing zeta potential, particle size, surface tension, wettability, capillary rise height, and scanning electron microscopy (SEM) tests. By virtue of electrostatic attraction, HGO could tightly adsorb to the shale surface, resulting in a hydrophobic blocking membrane, thereby greatly reducing water infiltration. Following interaction with shale at a concentration as low as 0.5 %, the water contact angle exhibited a notable enhancement, rising from 22.49° to 86.69°. And it could also decrease the capillary self-suction capacity of shale, further reducing water adsorption. Consequently, HGO exhibited significant potential for inhibiting hydration in shale drilling.

In response to the high water sorptivity of alkali-activated slag–red mud–steel slag cementitious material (AASRSS), water and aggressive ions are easily transferred to the interior of cementitious materials, which poses a significant threat to their durability. In order to limit the transfer of moisture and aggressive ions to the interior of AASRSS, sodium stearate (NaSt) was utilized in this paper to reduce its water sorptivity. The aim of this study was to elucidate the role of NaSt in the AASRSS system. The changes in the compressive strength and water sorptivity of AASRSS mortar were tested by mixing different amounts of NaSt into the mortar. The changes in the hydration process and microstructure of AASRSS after mixing with NaSt were analyzed by using the test methods of the isothermal calorimetry, resistivity, SEM and MIP. The results showed that NaSt plays an important role in the pore structure characteristics of AASRSS and that the use of NaSt significantly reduces its water sorptivity. The improvement in the water sorptivity was caused by two main mechanisms, namely the optimization of the pore structure (reduction in defects of the microstructure and alteration of pore size distribution) and the introduction of a hydrophobic film on the pore surface. The addition of NaSt did not change the type of AASRSS hydration product, but it inhibited the hydration reaction, leading to a reduction in the hydration product. The combination of the increased porosity and reduced hydration products mainly accounts for the decrease in the compressive strength of AASRSS due to NaSt.

Protein aggregation is believed to be a significant biological mechanism related to neurodegenerative disease, which makes the early-stage detection of aggregates a major concern. We demonstrated the use of terahertz (THz) time-domain spectroscopy to study protein-water interaction of monomeric and dimeric bovine insulin in aqueous samples. Regulated by changing pH and verified by size-exclusion chromatography and dynamic light scattering, we then measured their concentration-dependent changes in THz absorption between 0.5 and 3.0 THz and quantitatively deduced the extended hydration shell thickness by cubic distribution model and random distribution model. Under a random distribution assumption, the extended hydration thickness is 15.4 ± 0.4 Å for monomeric insulin and 17.5 ± 0.5 Å for dimeric insulin, with the hydration number of 6700 and 11,000, respectively. The hydration number of dimeric insulin is not twice but 1.64 times that of monomeric insulin, further supported by the ratio of solvent-accessible surface area. This “1.64-times” relation probably originates from the structural and conformational changes accompanied with dimerization. Combined with the investigations on insulin samples with different single amino acid mutations, residue B24 is believed to play an important role in the dimerization process. It is demonstrated that THz time-domain spectroscopy is a useful tool and has the sensitivity to provide the hydration information of different protein aggregates at an early stage.

Graphene nanoplates (GNPs) own the growth-potential application in high performance composites materials, and its homogeneously dispersion shows a significant impact on properties of composites. In this paper, GNPs were highly dispersed in aqueous solution with dispersants and treated by ultra-sonication and then incorporated in cement composites. The dispersion effect of different dispersants with ultrasonic treatment on GNPs was represented by UV-absorbance. The effect of dispersion GNPs on rheological properties of GNPs/cement pastes were studied by viscometer. And the early hydration process analysis of GNPs/cement composites was monitored by isothermal calorimetry (TAM Air) and 29Si NMR analysis. In addition, the microstructure and morphology of GNPs and cement composites were shown by SEM, which was the strong support of mechanism of GNPs dispersion in aqueous solution, and effect of dispersed GNPs on hydration and enhancement in cement composites. As a conclusion, GNPs can be dispersed uniformly in aqueous solution with the CO890 concentration of 0.7 g l−1, and viscosity of GNPs/cement pastes decreased because of high specific surface area of GNPs. And early hydration process had been accelerated owning to the free ions exchange resulting from the high adsorption capacity of GNPs for calcium ions and more supererogatory reaction area of GNPs.

Hydration of nitriles has been practically used for the production of amides, wherein the homogeneous catalysts including acids/bases and metal complexes are generally employed. Here, we report that nanorod manganese oxide (NR-MnO2) as a sustainable and low-cost heterogeneous catalyst is highly active and selective for the hydration of aromatic, heterocyclic, and aliphatic nitriles into the corresponding amides. The catalytic properties of NR-MnO2 significantly outperform that of commercial Pd/C and Ru/C catalysts and even the state-of-the-art homogeneous catalysts in the literature. In the continuous recycling tests, the NR-MnO2 catalyst exhibited excellent durability with negligible deactivation, which offers a good opportunity for practical production of these chemicals in the future.
