Effectively harvesting low-grade waste heat dispersed in the surrounding environment is critical for current energy recovery. Gel thermocells, which use ions as carriers to directly convert heat into electricity, have attracted increasing attention due to their high ionic thermopower and flexibility. However, the limited availability of redox couple poses a challenge to achieving high ionic thermoelectric (i-TE) performance. Herein, we propose a new redox couple, I − /IO 3 - , effectively utilized in the i-TE gel PAM/CMC-I - /IO 3 - -[HeMIM]Cl. By combining the thermogalvanic effect and the thermodiffusion effect, the i-TE performance is enhanced, demonstrating an n-type ionic thermopower of −11.1 mV K −1 and a normalized maximum output power density of 0.47 mW m −2 K −2 at 313 K. The mechanical properties of the i-TE gel exhibit 480% strain and strong adhesion to various materials. In addition, a gel device connecting twenty-five gel thermocells in series generates a high output voltage of 2.2 V, sufficient to drive a buzzer, highlighting the application potential of the i-TE gel with the I − /IO 3 - redox couple. This work broadens the range of redox couples applicable in i-TE systems, offering versatility for designing high-performance gels.

Radioiodine anions (I and IO 3 ) pose a serious threat to the environment and human health due to their high radioactivity and solubility. Therefore, it is important to develop efficient and economical adsorbent materials for radioiodine anions. In this work, combined with the excellent properties of chitosan (CS) and (3-acrylamidopropyl) trimethylammonium chloride (AMPTAC), a novel interpenetrating network hydrogel CS@AMPTAC was synthesized to improve the adsorption efficiency of CS hydrogel for I and IO 3 . Due to the electrostatic interaction and anion exchange ability of the quaternary ammonium group (−N + (CH 3 ) 3 Cl⁻), the introduction of AMPTAC constructs a more complex and effective adsorption sites for CS@AMPTAC. Combined with the protonated amino group (−NH 3 + ) in CS, the CS@AMPTAC showed better adsorption efficiency and anti-interference performance than CS. The CS@AMPTAC hydrogel shows excellent adsorption performance over a wide pH range (pH 2–11), which overcomes the sensitivity of traditional adsorbents to pH. Meanwhile, the maximum adsorption capacities of CS@AMPTAC for I and IO 3 are 359.9 mg/g and 312.64 mg/g, respectively, which exhibits remarkable enhancements of 246.26 mg/g and 267.34 mg/g compared to CS. In addition, based on the synergistic adsorption mechanism and the hydrophilicity of CS@AMPTAC, the hydrogel can reach adsorption equilibrium within 30 min. The synergic strategy shows great potential for application in the treatment of radioiodine anions.

Birefringent crystals are very important optical materials, which are widely used in the fields of optics and communication. In this work, we reported a new iodate, NaGaI3O9F, synthesized by mild hydrothermal method. NaGaI3O9F crystallized in the monoclinic space group P21/c (No. 14) and it featured a novel ∞[Ga2(IO3F)2(IO3)4]2− layer stacked with Na+ cations located in the void maintaining charge balance. Notably, IO3− and IO3F2− anionic units appeared in the same time in the A–Ga–I–O/F (A = alkali metal) system. According to the experimental characterization and theoretical calculations, NaGaI3O9F showed a wide bandgap (4.27 eV) and large birefringence (Δnexp ∼ 0.203, Δncal = 0.197 at 1064 nm), indicating its potential use as a birefringent material.

The synthesis, crystal and band structures and optical characterizations of a new polar thallium(I) vanadyl iodate, namely Tl(VO)2O2(IO3)3, are reported. Tl(VO)2O2(IO3)3 crystallizes in the orthorhombic polar space group Ima2 (No. 46) with a = 14.1143(17), b = 10.2116(12), c = 8.0319(9) Å, V = 1157.6(2) Å3 and Z = 4. The structure of Tl(VO)2O2(IO3)3 exhibits a 1D [(VO)2O2(IO3)3]− chain in which neighboring distorted VO6 octahedra are interconnected by both bridging oxo and iodate anions. The SHG measurements on Tl(VO)2O2(IO3)3, using a 2050 nm laser radiation, showed a moderate strong SHG response of 1.2 × KTP(KTiOPO4). Furthermore, the material is phase-matchable. Theoretical calculations based on DFT methods were performed by using the total-energy code CASTEP.

Aluminum (Al) has been widely used in solid composite propellants (SCPs) to increase the specific impulse. However, Al always subjects to coalescence , sintering to large agglomerations during combustion of SCPs resulting in larger two-phase flow losses. Herein, core-shell μ-Al@M(IO 3 ) x composites have designed and synthesized as a replacement for micron-sized Al (μ-Al) in the Al/AP/RDX/HTPB propellant with tunable combustion behavior. The results show the thermal reactivity and heat releases of SCP are largely enhanced by using these novel metal-based composites. With the inclusion of μ-Al@EGCG@Fe(IO 3 ) 3 (EGCG: Epigallocatechin gallate), the major exothermic peak is reduced by 29.1 °C compared to the reference propellant with a heat release increase up to 5475 J g −1 , exceeding that of the reference sample (86 J g −1 higher). The burn rates are increased with the inclusion of μ-Al@(MIO 3 ) x , while the pressure exponent is higher. The SCP-1 (0.3), SCP-2 (0.18) and SCP-4 (0.25) that have relatively low pressure exponent and high burn rates are good candidates for future applications. The major condensed combustion products (CCPs) of these SCPs are Al 2 O 3 , Al 2.81 O 3.56 N 0.44 , Al 4 C 3 , Al 2 OC, AlN and C 7 H 18 ClN. The agglomeration can be reduced with a minor inclusion of μ-Al@M(IO 3 ) x due to the enhanced interfacial reactions, and the average CCP sizes (0.5 μm for SCP-1 and SCP-4) are even smaller than that of initial μ-Al (1.2 μm).

Two cationic functional woods with highly density nitrogen functional group are synthesized. • Q-BW and Gua-BW exhibit the fast uptake adsorption kinetics (within 5 min) of I - and IO 3 - through strong electrostatic interactions. • Gua-BW containing guanidine groups achieves roughly ten times the maximum IO3- sorption capacity of Balsa wood via electrostatic and redox. • Gua-BW, derived from renewable Balsa wood with low cost, displays excellent adsorption capacity and favorable reusability. Compared to conventional adsorbent carriers, Balsa wood (BW) has the superiority of being low-cost and environmentally friendly. Herein, quaternary ammonium-functionalized Balsa wood (Q-BW) and guanidine-functionalized Balsa wood (Gua-BW), as two cationic functional woods, are synthesized directly from natural Balsa wood via grafting high-density nitrogen-containing groups. The two modified woods exhibited remarkably high adsorption rates for I - and IO 3 - through electrostatic interactions, reaching adsorption equilibrium within 5 min. The maximum adsorption performance reached 120 mg·g −1 for I - and 220 mg·g −1 for IO 3 - , which was 10 times higher than that of natural Balsa wood. Notably, grafting with guanidino groups endows Gua-BW with redox ability, thereby significantly enhancing its adsorption performance for IO 3 - . Furthermore, Gua-BW demonstrates excellent reusability, retaining stable adsorption efficiency after 5 cycles. As a cationic porous wood material with ultrahigh positive charge density, Gua-BW possesses properties of being green, low-cost, renewable, and having significantly higher adsorption rates for I - and IO 3 - , which provides a new approach for applications in the field of iodine-containing wastewater purification.

The first series of metal phosphate iodates, namely, M(IO3)(HPO4)(H2O) (M = Sc 1, Fe 2, Ga 3, In 4), have been obtained through hydrothermal syntheses. The title compounds are isomorphic and crystallize in the monoclinic space group C2/c (No. 15). Their structures feature a three-dimensional (3D) network composed of 1D [M(HPO4)(H2O)]+ chains that are further bridged by IO3 groups, forming 1D tunnels based on eight-membered rings along the b-axis. Magnetic measurements revealed antiferromagnetic coupling interactions between magnetic centers in compound 2. The UV absorption spectra measurements revealed that compound 2 exhibits a broad absorption peak at about 427 nm. The TGA studies and IR spectra for compounds 1–4 were also performed.

Purpose Radioiodine is an inevitable product of nuclear fission during nuclear fuel reprocessing and nuclear accident and finally is brought back to surface soil by fallout. Iodine is very active and mobile in soil and may adversely affect human health due to bioaccumulation through the food chain. The aim of this study was to evaluate the immobilization efficiency of biochar on the mobility of iodine (I − ) and iodate (IO 3
− ) in soil near Qinshan Nuclear Power Plant. Materials and methods Biochar was produced from a widely available agricultural waste (rice husk) at a pyrolysis temperature of 350 °C. Biochar was applied to the soil at five application rates (0, 0.33, 0.67, 1, and 1.33%). The affinities of I − and IO 3
− with soil/biochar, the mobility of I − and IO 3
− in biochar-amended soil, and effects of soil pH and ionic strength on immobilization of biochar were assessed by the standard batch sorption and desorption tests. Results and discussion Rice husk-derived biochar exhibited strong affinities for I − and IO 3
− as compared to that of soil, with immobilization ability ( K
biochar / K
soil ) of 936.6 and 309.9, respectively. Results showed that addition of 1% biochar to soil could significantly reduce desorption of I − and IO 3
− from soil. In addition, immobilization efficiency of biochar was not affected by soil physicochemical properties such as pH and ionic strength. Conclusions Results suggested that the easily synthesized biochar could be a promising and environmentally friendly amendment for the efficient immobilization of soil I − and IO 3
− .

Iodates capable of exhibiting large second-harmonic-generation (SHG) response, wide transparent windows, and ease in crystal growth are an ideal materials class for the design of mid-infrared (IR) nonlinear optical (NLO) crystals. In previous research, we have presented a new strategy for effectively designing noncentrosymmetric iodates on the basis of the structure-directing properties of d0 transition-metal (TM) oxide fluoride anions. However, due to the d–d electronic transition of TM cations, the band gaps of these TM-containing iodates are relatively small. In this study, we substituted TM cations of β-Ba[VFO2(IO3)2] (BVIF) with In3+ cations and successfully synthesized the first F–-containing indium iodate, Ba[InF3(IO3)2]. It has a similar structure and exhibits an SHG response equivalent with that of BVIF. Remarkably, however, the band gap of Ba[InF3(IO3)2] is larger than that of BVIF. The analysis of the structure–property relationship indicates that the enlarged band gap mainly originates from the removal of TM cations. In addition, due to the strong anisotropic polarization of the [IO3]− groups, Ba[InF3(IO3)2] can also exhibit a large birefringence (0.172@1064 nm), which not only is helpful for the phase-matching ability of Ba[InF3(IO3)2] in a wide wavelength range but also suggests that Ba[InF3(IO3)2] may be a potential birefringent crystal.

A new series of platinum iodates, namely, α-(H3O)2Pt(IO3)6, β-(H3O)2Pt(IO3)6, and A2Pt(IO3)6 (A = Na, K, Rb, Cs), have been synthesized. Interestingly, among these six stoichiometrically identical compounds, α-(H3O)2Pt(IO3)6 is polar, whereas other compounds are nonpolar and centrosymmetric. They all consist of zero-dimensional [Pt(IO3)6]2– molecular units separated by H3O+ or A+ cations. All of the lone electron pairs of the IO3– groups are aligned and almost point to one direction for α-(H3O)2Pt(IO3)6, whereas IO3– groups are located trans to each other in other compounds. The material, α-(H3O)2Pt(IO3)6, exhibits very strong second harmonic generation (SHG) effects, approximately 1.2 × KTiOPO4 (KTP), and is phase-matchable. Thermogravimetric analysis, elemental analysis, infrared spectra, UV–vis spectra, nonlinear optical properties, and theoretical calculations are also reported.
