“…472.25 and 449.22 K are the endset and onset of the peak, respectively. The net specific heat capacity ( C p ) in between this temperature range is 4.14 × 10 −2 J/g K. In complex mixture B, the phase change (endothermic) is observed at 459.62 K. The net specific heat capacity in this range of temperature is −4.99 × 10 −2 J/g K. The endset and onset of the peak are 474.83 and 440.87 K. This phase change is due to Cu 3 (PO 4 ) 2 H 2 O 43 . In this peak, from 442.71 to 460.15 K is totally endothermic with specific heat capacity ( C p ) of 1.13 J/g K. This particular heat capacity may be due to the high imidazole composition 47 .…”

Herein, the synthesis, characterization and thermal behaviour of imidazole-based two copper-phosphate mixtures, A = Cu 2 (PO 4 )(OH)ÁCu(HPO 4 )(H 2 O)Á(C 3 H 4 N 2 ) 2 . 3.25 H 2 O and B = Cu 3 (PO 4 ) 2 H 2 OÁ(C 3 H 4 N 2 ) 3 (H 2 O)Á0.1(C 3 H 4 N 2 ).3.25 H 2 O are reported. The characterization was done by adopting various electro-analyticaltechniques such as elemental analysis, X-ray Powder Diffraction (XRD), Thermogravimetric Analysis (TGA) and Derivative Thermogravimetry (DTG), Fourier Transform Infrared (FT-IR) Spectrometry, Absorption Spectrophotometry and Ultraviolet-Visible and near Infrared (UV-Vis-NIR). Differential Scanning Calorimetry performed with the heating rate 10 K/min from 297.96 to 770.46 K in normal atmosphere for both mixtures. DSC data indicated that both mixtures A and B are exhibiting exothermic property by their net specific heat capacities (C p ) −11.11 and −2.83 J/g K, respectively. Therefore, these complex mixtures can be utilized as heat dissipation materials. Both mixtures A and B undergo phase change in terms of hydrated phase to dehydrated phase up to 356 and 392 K, respectively. The specific heat capacity of Mixture A during hydration, C p = 2.54 J/g K, is higher than the tin, lead, stainless steel, glass and aluminium at their respective melting points. This mixture is also found better than the commercial product based on lithium ion battery in terms of specific heat capacity. From UV-Vis-NIR analysis, it is found that the mixtures A and B are showing semiconducting behaviour with band gaps 1.66 and 1.68 eV, respectively. The average crystallite sizes of these nano-complex mixtures are 35.29 and 30.94 nm and these were calculated using the Debye-Scherrer equation and Williamson-Hall method.

“…X‐ray diffraction (XRD) patterns of the synthesized Cu@GOD and Cu 3 (PO 4 ) 2 were consistent with the standard Cu 3 (PO 4 ) 2 •3H 2 O card (the card number is NO. 22–0548) [ 10 ] (Figure S10, Supporting Information), indicating the favorable crystallinity. Scanning transmission electron microscopy mapping of Cu@GOD demonstrated that GOD was uniformly distributed into Cu 3 (PO 4 ) 2 scaffold (Figure 1c).…”

The high proliferation efficiency, redox imbalance, and elevated nucleic acid repair capabilities of tumor cells severely restrict the theranostic efficacy. Selectively interference chaotic tumors with devastating nucleic acid damages (NUDs) properties are expected to overcome theranostic barriers. Here, an exquisite catalytic‐based strategy with comprehensive NUDs mechanisms is demonstrated. In this regard, enzyme (glucose oxidase, GOD) symbioses nanozyme Cu3+x(PO4)2 through biomineralization (abbreviated as Cu@GOD), GOD can disorder the metabolism by consuming glucose, thereby inhibiting the nutrition supply for nucleic acid repair. GOD‐catalyzed H2O2 guarantees the self‐cyclic glutathione depletion and reactive oxygen species generation caused by Cu3+x(PO4)2, resulted the reduced antioxidation defense and enhanced oxidation assault, ensures an indiscriminate NUDs ability. Moreover, the high photothermal effect of Cu3+x(PO4)2 induces effective tumor inhibition. Consequently, this substantial multipath NUDs strategy, with potentials of suppressing the cytoprotective mechanisms, amplifying the cellular oxidative stress, and disrupting the redox balance to ensure substantial irreversible NUDs, completely breaks the obstacle of chaotic tumors, providing new conceptual thinking for tumor proliferation inhibition.
