With the increasing demand of high energy and power density for energy storage devices, aqueous zinc-based batteries with high safety and low-cost battery system, have attracted wide attention due to their inherent advantages. Herein, for the first time, fluorinated carbon (CF 0.95 ) materials are reported as cathodes for alkaline zinc batteries and exhibit unprecedented power and energy density. The results show that the material exhibits a very high specific capacity of 703.5 mAh/g as well as an ultrahigh energy density up to 795.5 Wh/kg at a current rate of 50 mA/g (0.071C). Besides, it still holds high capacity of 416.7 mAh/g when discharged at a rate of 50000 mA/g (71C), indicating an outstanding power performance of 25066.0 W/kg. The corresponding capacity can even reach to 170.6 mAh/g, 706 mAh/g and 562.6 mAh/g when it is evaluated at a current rate 0.71C under −20 °C, 0 °C and 50 °C respectively. Finally, electrochemical discharge mechanism based on the conversion reaction is also further uncovered by XRD and SEM characterization and EDS elemental analysis. In conclusion, the alkaline Zn/CF x new-type primary battery systems with excellent properties developed here might show broad application prospects.

Spin excitation continua observed in neutron scattering studies are often considered to be strong evidence of quantum spin liquid formation. In a disorder-free magnetic compound with a quantum spin liquid ground state, the elementary excitation is no longer the conventional spin waves (magnons). Instead, the magnons fractionalize into spinons, producing a characteristic two-spinon continuum. However, it remained uncertain whether a clean, ordered antiferromagnet could exhibit a continuous spectrum similar to that of a quantum spin liquid. This paper presents evidence of a spin excitation continuum in the magnetically ordered state of Na 2 BaCo(PO 4 ) 2 , where free spinons are absent. This challenges the interpretation of such a continuum as a definitive signature of a quantum spin liquid in new material studies.

Radiative cooling textiles dissipate human body heat without any energy input, providing a sustainable means for personal thermal management. However, there is still a lack of textile materials to support efficient cooling in varied outdoor and indoor environments. Here we show a polyoxymethylene (POM) nanotextile design that not only achieves selective emission in the atmospheric window (8–13 μm) but also shows transmission in the remaining mid-infrared wavebands and reflection of sunlight (0.3–2.5 μm). As a result, the POM textile achieves efficient radiative human body cooling both outdoors (under sunny and cloudy conditions) and indoors (0.5–8.8 °C lower than typical textiles). Moreover, the textile design shows favourable wearability and outperforms its commercial counterparts when used as protective clothing. The POM material provides both indoor and outdoor human body cooling and introduces new possibilities in the rational design of next-generation smart textiles and other applications supporting sustainability.

Lysosomes maintain an acidic pH of 4.5–5.0, optimal for macromolecular degradation. Whereas proton influx is produced by a V-type H + ATPase, proton efflux is mediated by a fast H + leak through TMEM175 channels, as well as an unidentified slow pathway. A candidate screen on an orphan lysosome membrane protein (OLMP) library enabled us to discover that SLC7A11, the protein target of the ferroptosis-inducing compound erastin, mediates a slow lysosomal H + leak through downward flux of cystine and glutamate, two H + equivalents with uniquely large but opposite concentration gradients across lysosomal membranes. SLC7A11 deficiency or inhibition caused lysosomal over-acidification, reduced degradation, accumulation of storage materials, and ferroptosis, as well as facilitated α-synuclein aggregation in neurons. Correction of abnormal lysosomal acidity restored lysosome homeostasis and prevented ferroptosis. These studies have revealed an unconventional H + transport conduit that is integral to lysosomal flux of protonatable metabolites to regulate lysosome function, ferroptosis, and Parkinson’s disease (PD) pathology.

A tandem Hexadehydro-Diels–Alder (HDDA)/[2 + 2] cycloaddition/aryl migration reaction of iodonium ylide with tetrayne is described, in which iodonium ylide served as a unique double bond and reacted with aryne to form a four-membered iodonium(III) cycle, then converted to iodoarene after aryl group migration from iodine to adjacent carbon. This strategy allows the efficient construction of fully substituted iodoarene compounds.

Despite the critical role actinide decorporation agents play in the emergency treatment of people in nuclear accidents and other scenarios that may cause internal contamination of actinides, new ligands have seldom been reported in recent decades because the current inventory has been limited to only a handful of functional groups. Therefore, new functional groups are always being urgently sought for the introduction of advanced actinide decorporation agents. Herein, a tropolone derivative, 2-hydroxy-6-(propan-2-yl)cyclohepta-2,4,6-trien-1-one (Hinokitiol or Hino), is proposed to be a promising candidate for this purpose by virtue of its well-demonstrated high membrane permeability and high affinity for metal ions. The coordination stoichiometry of Hino with uranyl is demonstrated to be 3:1 both in an aqueous solution (pH 7.4) and in the solid state. The results of a liquid–liquid extraction experiment further show that Hino exhibits strong chelating ability and selectivity toward uranyl over biological essential metal ions (i.e., Mn2+, Zn2+, Co2+, and Ni2+) with an extraction efficiency of >90.0%. The in vivo uranyl removal efficacies of Hino in kidneys and bone of mice are demonstrated to be 67.0% and 32.3%, respectively. On the basis of the observations described above, it is highly possible that further modification of Hino will lead to a large family of multidentate agents with enhanced uranyl decorporation ability.

Electrolyte regeneration is an important goal for environmental protection and sustainable development efforts. Herein, we report a facile strategy inspired by the transformation of edible dough from flour to regenerate hydrogel electrolytes from their dehydrated copolymer granules (CGs) via direct addition of water or salt solution. With the aid of heating, this procedure is efficient, relatively quick, and easily implemented. The dehydrated CGs are lightweight, reusable and stable under long-term storage. Even after 5 cycles of dehydration and regeneration, the regeneration efficiency of the hydrogel electrolytes, as evaluated based on retention of mechanical strength, is over 60%. The regenerated electrolytes possess considerable ionic conductivity, reprocessability, and 3D-printability. Furthermore, an all-gel supercapacitor assembled from the regenerated hydrogel electrolyte and activated carbon electrode with CGs as binder demonstrates excellent interfacial compatibility. The assembled all-gel supercapacitor can maintain 98.7% of its original specific capacitance after 100 bending tests, and can operate in a wide temperature range spanning from −15 to 60°C. This work may provide a new access to the development of renewable materials for various applications in the fields of intelligent devices, wearable electronics and soft robotics.

Birefringent materials play a key role in modulating the polarization of light and thus in optical communication as well as in laser techniques and science. Designing new, excellent birefringent materials remains a challenge. In this work, we designed and synthesized the first antimony(III) fluoride oxalate birefringent material, KSb 2 C 2 O 4 F 5 , by a combination of delocalized π-conjugated [C 2 O 4 ] 2− groups, stereochemical active Sb 3+ cations, and the most electronegative element, fluorine. The [C 2 O 4 ] 2− groups are not in an optimal arrangement in the crystal structure of KSb 2 C 2 O 4 F 5 ; nonetheless, KSb 2 C 2 O 4 F 5 exhibits a large birefringence (Δ n =0.170 at 546 nm) that is even better than that of the well-known commercial birefringent material α-BaB 2 O 4 , even though the latter features an optimal arrangement of π-conjugated [B 3 O 6 ] 3− groups. Based on first-principles calculations, this prominent birefringence should be attributed to the alliance of planar π-conjugated [C 2 O 4 ] 2− anions, highly distorted SbO 2 F 2 and SbOF 3 polyhedra with a stereochemically active lone pair. The combination of lone-pair electrons and π-conjugated systems boosts the birefringence to a large extent and will help the development of high-performance birefringent materials. Graphical A synergistic combination of different functional groups has led to the first antimony(III) fluoride oxalate material, KSb 2 C 2 O 4 F 5 , to exhibit a birefringent response (Δ n =0.170 at 546 nm); this value is larger than that of the commercial α-BaB 2 O 4 , despite its suboptimal anisotropic structure.

In this paper, coenzyme Q 10 (Ubiquinone, CoQ 10 ) was used for the first time as a transducer to construct electrochemical biosensor for effectively detecting γ- l -glutamyl- l -cysteinyl-glycine (glutathione, GSH). CoQ 10 modified electrode was fabricated by attaching its gel mixed with multi-walled carbon nanotubes (MWNTs)/ionic liquid (IL). In the optimum conditions, based on the increasing of reduction peak current of CoQ 10 caused by GSH through voltammetric technology, it was found that the peak current of CoQ 10 was linear with the concentration of GSH in the range from 4.0×10 −9 to 2.0×10 −7 mol L −1 at the pH 7.00, and the limit of detection was 3.2×10 −10 mol L −1 ( S / N =3). The results revealed that this method could be used to determine GSH in actual blood samples with the superiority of excellent selectivity , high stability and sensitivity. The strategy explored here might provide a new pathway to design novel multi-function transducers for detecting GSH, which has unique characteristic and potential application in the fields of sensor and medical diagnosis.

In this study, Tm 3+ -doped Ca 2 MgWO 6 (CMWO) phosphors were prepared and thoroughly analyzed. The structure, luminescent and temperature-dependent behavior of the phosphors were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), photoluminescence (PL) and excitation (PLE) spectra, along with temperature-dependent PL spectroscopy . XRD and SEM analysis confirmed the successful preparation of a pure-phase double perovskite structured Ca 2 MgWO 6 phosphor with successful Tm 3+ doping. The PL spectrum indicates that the phosphor emits light under both 285 nm and 361 nm excitation. The PLE spectrum reveals that the optimal doping concentration of Tm 3+ for 285 nm excitation is 0.007, while for 361 nm excitation, it is 0.08. The phosphor was then tested for variable-temperature emission spectra , and its temperature-sensing performance was evaluated using the fluorescence intensity ratio (FIR) method. Under 361 nm excitation, the CMWO:0.08 Tm 3+ phosphor exhibited a maximum relative sensitivity ( S r(max) ) of 2.33 % K −1 at 348 K, within the temperature range of 198–348 K. When excited at 285 nm, the CMWO:0.007 Tm 3+ phosphor displayed strong temperature dependence in the range of 98–223 K, with an S r(max) of 14.71 % K −1 at 223 K, surpassing many thermometric phosphors reported in the literature. These results highlight the significant potential of CMWO:Tm 3+ phosphors as highly sensitive optical temperature sensors, particularly for low-temperature applications.

Potassium (K) cannot be produced by molten-salt electrolysis due to its high vapor pressure and erosion of the graphite anode by K. To overcome this problem, a liquid tin (Sn) electrode was employed to enable the electrolysis by accommodating K in the form of K-Sn alloy that can be separated into K gas and Sn by a following distillation approach. The so-called electrolysis-distillation (ED) approach was conducted in molten K 2 CO 3 -KCl along with a nickel (Ni)-based inert oxygen-evolution anode at 150 to 700 mA/cm 2 at 700 °C. The K-Sn alloys were obtained with a current efficiency of >70 pct at 350 mA/cm 2 without harmful chlorine gas (Cl 2 ) generation, and the chemical diffusion coefficient of K in liquid Sn is ~ 5.21×10 −5 cm 2 /s. Moreover, the Ni-based alloy inert anode was stably served for over 100 hours. The vacuum distillation was conducted at 650 °C for 90 minutes to obtain K metal with a purity of 99.99 pct and a recovery rate of 93.5 pct. Therefore, the ED approach developed here is an efficient and clean route to produce K metal.

Natural halloysite nanotubes (HNTs) modified with 3-aminopropyltriethoxysilane were used as an aspirin carrier. The structure, drug loading and release profiles of samples were characterized by X-ray diffraction (XRD), thermogravimetry-differential scanning calorimetry (TG-DSC), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and UV-spectrophotometry. The Higuchi model Q = kt0.5 was employed to analyze the dissolution data in detail. The results indicated that the modification of HNTs could improve the amount of aspirin from 3.84 to 11.98 wt%. The physical state of aspirin was nanocrystalline and amorphous affected by the confined space of HNTs, which significantly enhanced the dissolution rate created by a burst release within the first hour. The linearity of the Higuchi equation indicated that the aspirin release mechanism for modified HNTs was fitted to Fick's diffusion and the dissolution rate was slower than that of natural HNTs. The as-synthesized N-HNTs could have interesting potential application in drug carrier systems.
