Lithium nitrate (LiNO 3 ) has been widely applied as an additive to effectively protect lithium (Li) metal anode via enhancing the interfacial stability. However, few researches have been carried out to protect Li metal anode with LiNO 3 in carbonate electrolyte, because of its sparingly solubility. Herein, we propose a concept of sustainably and controllably releasing NO 3 − in carbonate electrolyte by intercalating superfluous LiNO 3 particles between bi-layer polypropylene (PP) membranes (PP/LiNO 3 /PP). The sandwiched biscuit-like configuration prevents the direct attachment of non-conducting LiNO 3 to active materials, facilitating the battery operation. Moreover, this construction is conductive to form uniform and stable solid electrolyte interphase (SEI) in virtue of Li–N compounds on Li metal by slow but continuous releasing of NO 3 − from LiNO 3 particles. Li metal anode with the PP/LiNO 3 /PP configuration showed a high Coulombic efficiency of over 95.3% after 550 cycles at a current density of 1 mA cm −2 . When paired with LiNi 0.80 Co 0.10 Al 0.10 O cathode, the Li metal full cell with the intercalated LiNO 3 particles could deliver a discharge capacity of 103.8 mAh g −1 at the 500th cycle at 1C current density, which is far superior to the performance of the cell without LiNO 3 additive. More profoundly, the PP/LiNO 3 /PP configuration is also applicable to the commercialized anode such as Silicon-Graphite to improve the electrochemical performance prominently. This strategy is not only a facile and efficient way in protecting Li metal anode, but also a universal method enabling the additives with sparingly solubility to be widely used in modern energy industries.

The research on nonlinear optical (NLO) crystals is mainly focused on two relatively separate systems, π-conjugated or non-π-conjugated systems, respectively. In this work, we report a new NLO crystal Na10Zn(NO3)4(SO3S)4 combining inorganic π-conjugated [NO3] and non-π-conjugated heteroanion [S2O3] groups, which was synthesized by the aqueous solution method. In the structure, the similar coexistence of planar triangular anionic groups (π-conjugated) and heteroanion tetrahedra (non-π-conjugated) is rarely mentioned, which provides a new approach for designing NLO crystals. Notably, this compound exhibits a phase-matching second-harmonic generation (SHG) response 1.2 times that of KH2PO4. In addition, birefringence, absorption edge and theoretical calculations are also reported in this article. This work provides a new designing route to expand NLO systems via combining planar π-conjugated and non-π-conjugated heteroanion groups.

To improve the single-layer all-solid-state ion selective electrode’ defects including poor conductivity of PVC sensitive membrane and interference of water layer between substrate electrode and sensitive membrane, a double-layer all-solid-state ion selective electrode with nanomaterial as the solid contact layer and conductive polymer as the ion sensitive membrane was developed. A gold nanoparticles solid contact layer and a nitrate-doped polypyrrole molecularly imprinted polymer membrane were prepared by electrodeposition. The optimal parameters obtained by electrochemical performance test were 2.5 mmol/L HAuCl 4 electrolyte for solid contact layer and 1800s electrodeposition time for sensitive membrane. The new electrode exhibited a Nernstian response of -50.4 mV/decade and a low detection limit of 5.25×10 -5 mol/L. Potentiometric water layer test showed no water film formed between the gold nanoparticles solid contact layer and nitrate-doped polypyrrole molecularly imprinted polymer membrane. The contact angle between droplet and the surface of solid contact layer was 112.35° and showed good hydrophobic property. Furthermore, the developed electrode exhibited fast response, excellent potential stability and long lifetime. This electrode is suitable for the detection of nitrate concentration in water and liquid fertilizer.

Metal-organic frameworks (MOFs) are promising hosts for quasi-solid electrolytes (QSEs) by integrating liquid electrolytes (MOF@LE QSEs), yet stabilizing lithium metal anodes (LMAs) to enhance electrochemical performance remains a challenge. Here, we introduce a strategy leveraging open metal sites (OMSs) in HKUST-1 (Cu 3 (BTC) 2 ) combined with LiNO 3 to tailor solid electrolyte interphase (SEI) chemistry and lithium deposition. OMSs in HKUST-1 anchor NO 3 − and promote LiNO 3 dissociation, enriching SEI with nitrogen-containing inorganic compounds and enabling uniform and spherical lithium morphology. Consequently, LMAs with LiNO 3 -incorporated HKUST-1 membrane QSE (HM-LN QSE) achieve a critical current density of 2.7 mA cm −2 , with stable lithium plating/stripping over 650 h at 0.2 mA cm −2 and more than 300 h at 0.5 mA cm −2 . Moreover, LiLiFePO 4 cells assembled with HM-LN QSEs delivere a discharge capacity of 81.2 mAh g −1 at 5 C and retain 81.2% capacity after 350 cycles at 2 C, demonstrating superior electrochemical stability and performance. This innovative MOF-based approach significantly enhances SEI stability and LMA performance, advancing lithium metal battery technology.

Plastic scintillators inherently suffer from the limitation of low gamma-ray counting efficiency due to their low atomic number (Z). To address this, this study explored the incorporation of lead (II) nitrate (Pb(NO 3 ) 2 ), a high-Z material, into a photocurable resin. The Pb(NO 3 ) 2 -loaded plastic scintillators were fabricated using Digital Light Processing (DLP) type 3D printing, wherein dimethyl sulfoxide (DMSO) was employed as a co-solvent to ensure uniform dispersion of the Pb(NO 3 ) 2 within the polymer matrix. This uniform dispersion was confirmed by Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy (SEM-EDS) analysis of the scintillator's cutting surface. The evaluation of scintillation properties showed that the scintillator loaded with 5 wt% of Pb(NO 3 ) 2 exhibited a gamma-ray counting efficiency for a 137 Cs source that was 1.64 times higher than that of the commercial plastic scintillator, BC408. Although the optical transmittance decreased due to the addition of Pb(NO 3 ) 2 and DMSO, the 5 wt% Pb(NO 3 ) 2 sample maintained a relative light output of 55.51% compared to BC408. Additionally, the fast timing characteristics were preserved, with the loaded scintillators exhibiting a decay time of 3.23–3.41 ns, nearly identical to that of the unloaded sample.

MgCl 2 ·6H 2 O-Mg(NO 3 ) 2 ·6H 2 O eutectic has a proper melting point and high latent heat for solar water heating systems with latent heat storage . In this paper, the exact composition of the eutectic and the corresponding phase change temperature are determined by measuring the phase change characteristics of mixtures of MgCl 2 ·6H 2 O and Mg(NO 3 ) 2 ·6H 2 O in various ratios. MgCl 2 ·6H 2 O-Mg(NO 3 ) 2 ·6H 2 O eutectics, the melting temperature of which is around 58 °C, can be obtained with the mass fraction of MgCl 2 ·6H 2 O ranging from 35% to 50%. The eutectics are composited with porous fumed silica to improve its thermo-physical properties. The eutectic/SiO 2 composite retains a similar melting point of the pure eutectic, is of no liquid leakage even after melting while the SiO 2 weighs more than 15 wt%, and the specific enthalpy reaches 88.13 kJ kg −1 . The eutectic/SiO 2 composite has a thermal conductivity 5% higher than pure eutectics and better thermal stability and cycle stability. The thermogravimetric analysis shows its weight loss is 8.03% less than pure eutectic at 300 °C. And the eutectics suffers a decrease in phase change enthalpy after 100 thermal cycles by 9.2%, much lower compared with the 37.23% for pure eutectics due to the phase separation during the thermal cycles. Thermo-physical properties and stability of MgCl 2 ·6H 2 O-Mg(NO 3 ) 2 ·6H 2 O eutectic have been enhanced by fumed silica.

Adsorbents including CuCl 2 -AC, CuCl 2 -13X, Cu(NO 3 ) 2 -AC and Cu(NO 3 ) 2 -13X were prepared to remove trace phosphine from recycled hydrogen in the Siemens process of producing polysilicon , and adsorptive mechanisms were determined by X-ray diffraction and intermittent breakthrough experiments. CuCl 2 could disperse better on supporters than Cu(NO 3 ) 2 , and it existed in its original form. However, Cu(NO 3 ) 2 decomposed into copper oxide or basic cupric nitrate, and showed conspicuous thermal aggregation effect after calcination . Interactive effects between cupric components and supporters varied form species to species and deactivated the reactivity of CuCl 2 and Cu(NO 3 ) 2 in different degree, which resulted in disparities of adsorbents’ performances. CuCl 2 -AC and Cu(NO 3 ) 2 -AC had better performances than CuCl 2 -13X and Cu(NO 3 ) 2 -13X because cupric components were deactivated more when loaded on 13X zeolite. Chemical transformation of phosphine made adsorbents’ surface renewable, and the renewed rate depended on the reactivity of cupric components. All of adsorbents showed significant recoveries of efficiencies in intermittent experiments.

5-Aminotetrazole (5AT)/strontium nitrate (Sr(NO 3 ) 2 ), as a novel energetic material and low-emission nitrogen-rich fuel, has been extensively applied to the formulations of solid propellant gas generators (SPGGs) fire extinguishing technology due to its advantageous physicochemical characteristics. However, the shortcomings of high combustion temperature and low burning rate of this energetic material formulation of 5AT/Sr(NO 3 ) 2 restrict its further application and development in SPGGs fire extinguishing technology. To address these existing problems and enhance its combustion behaviors, lead carbonate salts (lead carbonate or basic lead carbonate) are incorporated as combustion modifiers in this study, and systematically investigates the effects of these two modifiers on its thermal decomposition and combustion behaviors. The results show that after adding them, the samples all exhibit three pyrolysis stages. Since the additives exhibit incomplete thermal decomposition during the initial stage, they show little catalytic effect on the first pyrolysis stage, and the catalytic effects are mainly reflected in the latter two stages. In addition, both additives show good cooling effects, significantly reducing the combustion temperature of propellant. The maximum burning rate of the samples with additives is higher than that of 5AT/Sr(NO 3 ) 2 , and the samples with 2PbCO 3 •Pb(OH) 2 demonstrates the superior burn rate over the samples with PbCO 3 . The findings establish both mechanistic understanding and practical guidelines for optimizing 5AT/Sr(NO 3 ) 2 propellant formulations in SPGG fire suppression systems.

Abstract Household water heating systems incorporating phase change materials (PCMs) can store solar thermal energy and reduce energy consumption. MgCl 2 ·6H 2 O–Mg(NO 3 ) 2 ·6H 2 O eutectics have a melting point near 60 °C with a large energy storage density suitable for use in the thermal energy storage unit of a water heating system. However, the low thermal conductivity of the eutectic limits its heat extraction rate. In this study, we combine the eutectic and expanded graphite (EG) to prepare a high thermal conductivity composite PCM and study its cycling performance over 200 thermal cycles. The thermal conductivity of the composite PCM increased from 0.5 to 3.7 W m −1 K −1 , ensuring faster heating and cooling. The images obtained from scanning electron microscopy and leakage testing showed that the maximum loading mass fraction of the eutectic in the EG reached 85 wt %. Infrared spectra and X-ray diffractometry patterns confirm that composites with compositions between those of EG and the eutectic were composed of the physical mixture. Thermogravimetric analysis indicated that the composite PCM lost less mass at 300 °C compared to the pure eutectic, and differential scanning calorimetry demonstrated that the composite PCM had a melting point of 52.3 °C and a small subcooling degree of 2.7 °C, compared to 56.6 and 18.4 °C for the pure eutectic, respectively. All these measurements demonstrated that the composite PCMs changed less after 200 thermal cycles than the pure eutectic, which had an observable stratification caused by phase separation. The composite PCM developed was thermally conductive, shape-stabilized, and more thermally stable during cycling than the pure eutectic. Graphical Abstract

5-Aminotetrazole/strontium nitrate (5AT/Sr(NO 3 ) 2 ) propellant is widely utilized as green gas generating agent in fire extinguishers. To enhance the combustion rate and modify the gas production performance of 5AT/Sr(NO 3 ) 2 propellant, this study investigated the catalytic effects of adding different metal oxides (Bi 2 O 3 , PbO, TiO 2 , and CoO) on its pyrolysis and combustion process. The pyrolysis behavior, pyrolysis mechanism and combustion performance of 5AT/Sr(NO 3 ) 2 propellants were studied by using thermogravimetry (TG), derivative thermogravimetry (DTG), differential scanning caborimetry (DSC), mass spectrometry (MS), fourier transform infrared spectroscopy (FTIR) analysis and closed bomb vessel tests. Experimental results indicated that Bi 2 O 3 and PbO predominantly facilitated the thermal decomposition process of 5AT, while TiO 2 and CoO primarily catalyzed the thermal decomposition of Sr(NO 3 ) 2 . Certainly, the addition of metal oxides as catalysts to 5AT/Sr(NO 3 ) 2 propellant holds significant potential for improving the application as a gas generating agents in fire extinguishers.

The development of robust strategies for designing high-performance ultraviolet (UV) birefringent materials has become a critical challenge. The combination of alkali metal and Ca2+ cations, which do not exhibit d–d or f–f transitions, with [NO3]− anions that possess high polarizability anisotropy results in the synthesis of three hydrated alkali metal calcium nitrates, ACa(NO3)3·2H2O (A = NH4, Rb, Cs). The title compounds were synthesized at room temperature using the water solution–evaporation technique, featuring a unique chain-like structure composed of [CaO9] polyhedra and [NO3]− units. The compounds exhibit notable optical properties, including short UV absorption edges (220–235 nm) and moderate birefringence (0.077–0.086 at 546 nm). Detailed structural investigation and theoretical analyses reveal that the birefringence is primarily due to the planar triangular arrangement of the [NO3]− groups. This research not only increases the structural diversity within inorganic materials but also provides a key approach for further studies of all-inorganic birefringent optical materials in the UV region.

Silver-based adsorbents have demonstrated exceptional performance in capturing gaseous radioactive iodine from nuclear fuel reprocessing plants. However, their widespread industrial applications have been hindered by high costs. In this paper, K 2 Hg(NO 3 ) 4 @SiO 2 was first studied to trap gaseous iodine, which was synthesized by hydrothermal reaction, impregnation treatment and drying processing. K 2 Hg(NO 3 ) 4 was used as the adsorption active sites and was uniformly dispersed in the silica gel. The static adsorption capacities of K 2 Hg(NO 3 ) 4 @SiO 2 for I 2 and CH 3 I were 253.5 ± 2.3 mg/g and 257.7 ± 5.4 mg/g, respectively. The dynamic adsorption capacities of K 2 Hg(NO 3 ) 4 @SiO 2 were 200.2 mg/g and 131.3 mg/g at the inlet concentrations of 20.0 ± 0.5 mg/L and 5.2 ± 0.2 mg/L of I 2 , respectively. Furthermore, the dynamic adsorption capacities of K 2 Hg(NO 3 ) 4 @SiO 2 were 198.2 mg/g and 127.7 mg/g at the inlet concentrations of 7.6 ± 0.3 mg/L and 2.8 ± 0.2 mg/L of CH 3 I, respectively. The adsorption mechanistic analyses revealed that the I 2 was primarily captured through the formation of HgI 2 and Hg(IO 3 ) 2 , while the CH 3 I was predominantly captured in the form of HgI 2 . Regarding stability, K 2 Hg(NO 3 ) 4 @SiO 2 exhibited excellent stability in environments with strong oxidizing, strong radiation and high temperatures. More importantly, the cost of K 2 Hg(NO 3 ) 4 @SiO 2 was less than one-third that of silver-based adsorbents. Generally, the K 2 Hg(NO 3 ) 4 @SiO 2 gained advantages in adsorption performance and application cost, which was a promising alternative to silver-based adsorbents.
