Summary Zinc-loaded whey protein nanoparticles were prepared by enzymatic cross-linking whey protein followed by ethanol desolvation. Whey protein isolate (WPI) was denatured by heating (80 °C for 15 min) at pH 7.0 and then cross-linked by transglutaminase at 50 °C for 4 h while stirring. Transglutaminase was inactivated by heating at 90 °C for 10 min, and then, ZnSO 4 ·7H 2 O (1–10 m m ) was added. Zinc-loaded whey protein nanoparticles were formed by adding ethanol at one to five times the volume of the protein solution at pH 9.0. The desolvated solutions were diluted by adding distilled water at ratio of 1:100 (w/v) immediately after desolvation. Dynamic light scattering (DLS) data showed that the particle size of zinc-loaded whey protein nanoparticles increased with the amount of zinc and the volume of ethanol. Scanning electron microscopy micrographs revealed an almost spherical morphology for zinc-loaded whey protein nanoparticles. The zinc loading efficiency was determined ranging from 76.7% to 99.2%. In vitro test data showed that the zinc release rate was low in simulated gastric fluid but high in simulated intestinal fluid. The results indicated that enzymatic cross-linked whey protein nanoparticles may be used as a good vehicle to deliver zinc as a supplement.

The depth-separation of arsenic from antimony is crucial for achieving high-purity antimony metal. Chlorinated distillation has shown to effectively lower arsenic levels to just a few ppm, making it a promising method for arsenic impurity removal. However, many aspects of the deep separation mechanism of arsenic remain unexplored, posing technical barriers to effective arsenic removal in high-purity antimony production. This work introduces a “chlorine/oxygen affinity selective distillation” model to elucidate the mechanism underlying arsenic and antimony separation in chloride systems. Through thermodynamic analysis and quantum chemistry calculation, we demonstrate that arsenic species in different oxidation states exhibit markedly distinct affinities for chlorine and oxygen. The critical factor is the change in the solvation structure of As 3+ as it interacts with Cl − , while the strong binding affinity between As 5+ and oxygen inhibits chloride-mediated desolvation. Thus, HCl concentration plays a pivotal role in enhancing the separation efficiency of As 3+ from Sb 3+ . Experimental results reveal that increasing HCl concentration from 5 mol/L to 7 mol/L boosts arsenic removal efficiency by 5.7 %. This mechanism may offer broader applications for the efficient separation of similar elements in chloride systems.

In this study, an alkaline earth metal doped molybdenum disulfide composite (AEM@MoS 2 , AEM = Ca, Sr, Ba) was presented, which can convert the desolvation process from non-spontaneous to spontaneous during heavy metal adsorption. The doping of MoS 2 by AEM not only increases the ratio of surface-active phases, but also modulates the energy band structure, so that Pb 2+ in solution was spontaneously exposed from the hydrated clusters and was more easily adsorbed on the AEM@MoS 2 surface. Among them, the maximum adsorption amount of Ba-MoS 2 reached 147.84 mg/g and the selectivity coefficient for Pb 2+ was as high as 254.58. The precipitation experiments yielded a Pb 2+ precipitation rate of 10.94 % under the condition of pure water, and molecular dynamics simulation (MD) yielded the diffusion coefficient of Pb 2+ being adsorbed on the surface of Ba-MoS 2 to be only 2.00 × 10 -4 Å 2 ·ps −1 . It was verified that it has excellent anchoring ability for Pb 2+ and effectively avoids the secondary pollution caused by desorption. This work can provide a new idea for improving the mechanism of the heavy metal hydrated ion adsorption process.

Resmetirom (MGL-3196) can form masses of solvates with a variety of solvents. In this study, a series of solvates, including those reported in patents and newly discovered solvates, were prepared by experimental screening. Hansen solubility parameters (HSPs) were used to investigate the formation rules of MGL-3196 solvates, and the results showed that the formation of MGL-3196 solvates was most related to the parameter Δ δ t . When the Δ δ t value between MGL-3196 and solvent was less than 14.23 MP0.5 a, MGL-3196 tended to form solvate with an accuracy of 84.09%. The precise crystal structures of six solvates and one solvent-free form (form A) were acquired by single crystal X-ray diffraction (SCXRD). After analyzing the structures of obtained solvates in-depth from the aspects of conformation, dimeric synthon, molecular packing, porosity and isostructuralism, the six solvates were classified into alcohol solvates (group 2), ester solvates (group 3) and other types of solvates (group 1). Generally, these three groups of solvates had completely different crystal structures. The solvates in group 1 and group 3 were channelized and isostructural in which solvents could be substituted without great influence on the structure, while in the alcohol solvates (group 2) solvents were fixed by strong hydrogen bonds to be a part of the crystal structure. Moreover, when solvates were desolvated, two metastable solvent-free forms (i.e., B and C) were crystallized and then transformed to form A through a structural rearrangement. The possible mechanisms for the phase transformation during different desolvation processes were finally proposed. All results shall provide an understanding and inspiration on the screening and production of polymorphic and pseudopolymorphic forms of MGL-3196 for the pharmaceutical industry.

Aqueous zinc-ion hybrid capacitors (ZIHCs) are a promising new type of energy storage device, but there is a plight that the unsatisfactory Zn 2+ storage capability of carbonaceous cathodes limits further application. To address this issue, desolvation strategy is employed to tailor the solvation sheath of Zn 2+ in the ultra-micropores (0.59 nm) nanospheres , where H 3 PO 4 acts as phosphorus source for forming C-P bonds and enhancing C=O bonds to further reduce the desolvation energy barrier. In practical application, a quasi-solid-state flexible ZIHC is constructed, which provides a battery-level energy density (293.4 Wh kg −1 ) at a power density (180 W kg − 1 ) and a remarkable capacity retention of 93.4 % after 10 000 cycles. Electrochemical analyses, DFT calculations and structural characterization reveal that ultra-microporous is proved to be a prerequisite for C-P/C=O that are expected to further deplete solvent molecules within a Zn 2+ solvation sheath. Also, the coupling effect between the strong adsorption of Zn 2+ by C-P/C=O and the hydrophobic effect of C-P play an important role in facilitating desolvation process. This work creates a precedent for the application of ultra-microporous carbon materials in ZHICs and provides a brand-new approach for breaking the bottleneck of the low energy density and poor lifespan of ZHICs.

High-performance sodium storage at low temperature is urgent with the increasingly stringent demand for energy storage systems. However, the aggravated capacity loss is induced by the sluggish interfacial kinetics, which originates from the interfacial Na+ desolvation. Herein, all-fluorinated anions with ultrahigh electron donicity, trifluoroacetate (TFA−), are introduced into the diglyme (G2)-based electrolyte for the anion-reinforced solvates in a wide temperature range. The unique solvation structure with TFA− anions and decreased G2 molecules occupying the inner sheath accelerates desolvation of Na+ to exhibit decreased desolvation energy from 4.16 to 3.49 kJ mol−1 and 24.74 to 16.55 kJ mol−1 beyond and below −20 °C, respectively, compared with that in 1.0 M NaPF6-G2. These enable the cell of Na||Na3V2(PO4)3 to deliver 60.2% of its room-temperature capacity and high capacity retention of 99.2% after 100 cycles at −40 °C. This work highlights regulation of solvation chemistry for highly stable sodium-ion batteries at low temperature.

Aqueous zinc-ion batteries (ZIBs) have received extensive attention due to the intrinsic advantages of high safety, low cost and environmental friendliness. But detrimental side reactions and dendrite problems resulting from high desolvation penalty and inhomogeneous Zn 2+ flux at the interface severely hindered their practical applications. Herein, a novel polyacrylamide-poly (ethylene glycol) diacrylate-carboxymethyl cellulose (PMC) hydrogel electrolyte is designed to overcome these obstacles through reducing the desolvation energy barrier and guiding the preferential orientation of Zn deposition simultaneously. Theoretical calculation and experimental results reveal that the desolvation activation energy of the PMC hydrogel electrolyte (36.42 kJ mol −1 ) is substantially lower than that of conventional ZnSO 4 aqueous electrolyte (62.31 kJ mol −1 ) due to the regulated Zn 2+ solvation structure. Based on the high binding energy between amide groups and Zn 2+ , polymer chains in PMC also serve as facile Zn 2+ transport channels to guide the uniform deposition behavior on the Zn (002) crystal surface, which is verified by the grazing incidence XRD analysis . Consequently, an ultra-long cycle life of 5000 h with a high coulombic efficiency of 99.5% is achieved by using the PMC hydrogel electrolyte. Considering the simple one-pot synthesizing method, the PMC hydrogel electrolyte provides new opportunities for developing practical ZIBs .

Rechargeable Mg batteries have gained great interest thanks to the abundant resources and high theoretical capacity of Mg metal anode. However, it suffers from severe passivation and extremely poor plating/stripping kinetics. Herein, a simple salt electrolyte system of Mg(OTf) 2 /MgCl 2 -DME is studied, and the poor Mg affinities on typical metal current collectors are revealed as the key factor for rapid cell failure. Accordingly, an interphase modification on Cu current collector by the in situ generation of a magnesiophilic Cu-thiourea (CuTU) complex is presented. It provides active sites for solvated Mg 2+ as well as Mg. This not only homogenizes Mg 2+ flux but also helps with the release of solvated species to lower the desolvation barrier. The high affinity with Mg further enables the dense and uniform growth of Mg deposits. Thanks to these merits, the facile and reversible plating/stripping of Mg is realized. As a result, the symmetric cells with Mg pre-deposited on CuTU-Cu electrodes stably operate for over 2600 h, which is a 34-fold increase in comparison to the standard Mg foil. Full cells coupling the Mg-CuTU-Cu anode and a PDI-EDA cathode with an N/P ratio of 3 deliver a high capacity of 251 mAh g −1 as well as stable cycling.

The large desolvation energy barrier of [Zn(H 2 O) 6 ] 2+ in aqueous zinc ion batteries (AZIBs) results in the undesirable [Zn(H 2 O) 6 ] 2+ formation, which leads to the uncontrollable water-induced side reactions and the intricately dendrites growth, thereby severely hindering the practical applications of AZIBs. Herein, we proposed boron-doped graphitic carbon nitride quantum dots (B-C 3 N 4 QDs) as an electrolyte additive for AZIBs. Experimental and theoretical calculations revealed that the doped B atoms could modulate the electron structure of the C 3 N 4 QDs, thus B-C 3 N 4 QDs played an enhanced catalytic role in efficiently decreasing the [Zn(H 2 O) 6 ] 2+ desolvation energy barrier to accelerate its desolvation kinetics in AZIBs, which led to releasing more free Zn 2+ , thereby suppressing side reactions and achieving highly reversible zinc plating/stripping to avoid the formation of zinc dendrites. Benefiting from these merits of B-C 3 N 4 QDs, the corresponding asymmetric Zn||Cu cell realized a high average Coulombic efficiency of 99.29 %. More importantly, the Zn||V 2 O 5 full cell with B-C 3 N 4 QDs still maintained a high specific capacity of ∼149.88 mAh g −1 at 5 A g −1 after 500 charging/discharging cycles, which was much higher than the battery without B-C 3 N 4 QDs at the same current density. This innovative design conception would inject new vitality to innovation of the low-cost, dendrite-free, and high-performance AZIBs and beyond.

Aqueous zinc-ion batteries (AZIBs) hold significant promise for energy storage; however, the high dissociation energy barriers of bulky hydrated zinc ions ([Zn(H2O)6]2+) induce uneven Zn deposition, leading to severe capacity degradation and a limited cycle life. Herein, an effective desolvation-enhanced zinc anode protective layer is constructed using Mo4/3B2–X nanosheets, in which the etching-induced metal vacancies and –F zincophilic sites endow the layer with a strong affinity for Zn2+ and effectively catalyze the desolvation of [Zn(H2O)6]2+. Experimental and theoretical calculations demonstrate that under the action of Mo4/3B2–X, the desolvation energy of [Zn(H2O)6]2+ can be effectively reduced from 38.99 kJ mol–1 of bare Zn to 27.67 kJ mol–1, significantly promoting greater flux and rapid diffusion of free Zn2+. As a result, this configuration achieves a dendrite-free Mo4/3B2–X-Zn anode with an ultralong cycling life exceeding 2000 h, which is 18 times that of bare Zn. Even under low-temperature conditions at 0 °C, the Mo4/3B2–X-Zn anode maintains stable cycling for over 2800 h with a low overpotential of 58 mV at 0.5 mA cm–2. Pairing with the KVO cathode, the full cell delivers a capacity of up to 291.2 mA h g–1 at 0 °C and the pouch cell achieves 256.9 mA h g–1 under a high mass loading of 9.5 mg cm–2, demonstrating promising commercial potential.

Calcium ion batteries (CIBs) are considered as an important candidate for post-lithium energy storage devices due to their abundance of resources and low cost. However, CIBs still suffer from slow kinetics due to the large solvation structure and high desolvation energy of Ca 2+ ions. Here, a solvation regulation strategy based on donor number (DN) is reported to achieve easy-desolvation and rapid storage of Ca 2+ in sodium vanadate (Na 2 V 6 O 16 ·2H 2 O, NVO). Specially, the solvent with a low DN, represented by propylene carbonate (PC), forms the first solvation shell of calcium ions with weak binding energy and small shell structure, which facilitates the migration of Ca 2+ in the electrolyte. More importantly, the low DN solvent is preferentially desolvated at the cathode/electrolyte interface, promoting the insertion of Ca 2+ into the NVO electrode. Mechanism studies further confirm the highly reversible uptake/release of Ca 2+ in the NVO cathode, along with the V O distance change in the coordination structure. Therefore, the NVO cathode achieves high capacity (376 mAh g −1 at 0.3 A g −1 ) and high-rate performance (151 mAh g −1 at 5 A g −1 ). The weak solvation effect strategy further improves the electrochemical performance and provides great importance for the design of the long-term development of CIBs.

A crystal engineering strategy has been adopted to prepare a porous high explosive, cyclotrimethylenetrinitramine (RDX). Raw RDX was crystallized with TMS, CAM, and HMPT (TMS = tetramethylene sulfone, CAM = ε-caprolactone monomer, and HMPT = hexamethylphosphoramide), forming three solvates, RDX·TMS, RDX·CAM, and RDX·HMPT, respectively. After desolvation by vacuum pyrolysis and antisolvent extraction, porous RDX containing micro- and nanoscale pores was successfully prepared. The porous RDX exhibits remarkably reduced impact, friction, and electrostatic spark sensitivity in comparison to raw RDX. A mechanism of the reduced sensitivity of porous RDX has also been proposed.
