“…Tb 2 O 3 /Y 2 O 3 /ZrO 2 = 5:4:2 (TYZ-1) crystal is successfully fabricated with the dimension of Φ5 mm × 20 mm, as shown in Figure a. The crystal was obtained without any cracks because the Zr 4+ -doped crystal has a good thermal insulation property, and it can reduce the thermal stress to obtain the high-quality single crystal. − Upon increasing Zr 4+ -doped concentration, the Tb 2 O 3 /Y 2 O 3 /ZrO 2 = 5:1:8 (TYZ-2) crystal has a higher melting point of 2600 °C . When precursor rods are held for about 3 h with an incident laser of 1.9 kW, which closes the device limitation of 2 kW, it is still difficult to maintain stability in the acquired heating zone due to the insufficient heating power.…”

Magneto-optical (M-O) crystals, with their large Faraday effects, low absorption coefficients, and high magnetic permeabilities, are widely used in the fields of optical modulators, isolators, phase shifters, optical switches, optical storage devices, optical displays, and laser gyroscopes. However, the commercialized terbium gallium garnet crystal has a low Verdet constant of 39−42 rad•m −1 •T −1 at 1064 nm and a laser-induced damage threshold of 1.14 GW/cm 2 (10 ns at 1064 nm), making it unable to meet the requirements of high-power devices. Based on the theoretical derivation of the Verdet constant, the critical factor that affects the Tb 3+ -doped Verdet constant is the number of Tb 3+ ions per unit volume N. Herein, we explore the new M-O crystal in a cubic oxide system with solid-phase sintering powder samples. By analyzing crystal structure and spectrum, calculated theoretical results indicate that the cubic oxide system Tb 2 O 3 /Y 2 O 3 /ZrO 2 crystals have a large Verdet constant. The optimal component of TYZ-1 is grown by the laser floating zone method. The theoretical calculation is consistent with the experimental result of 227 rad•m −1 •T −1 at 633 nm. Verifying the scientificity and rationality of the evaluation scheme was accomplished through experimentation. This work proposes a scheme for evaluating potential M-O crystals. We believe that this work will promote the exploration and development of M-O crystals.

“…Thermal conductivity plays a crucial role in determining the effectiveness of thermal insulation materials. − In accordance with ISO 22007-2:2015, we conducted a study on the thermal conductivity of YbFMs. The YbFMs with an apparent density of 35 mg·cm –3 exhibited a minimum thermal conductivity of 28.9 mW·m –1 ·K –1 , which is comparable to that of other ceramic products (Figure a,b). ,,− In addition, the operating temperature of YbFMs can reach up to 1350 °C, surpassing those of most lightweight insulation materials, such as SiO 2 composite fibrous membranes, , ceramic aerogels, ,− and anisotropic lamellar ceramic sponges .…”

Ultralow-density (35−60 mg•cm −3 ) Yb 2 O 3 nanofibrous membranes (YbFMs) with a multilayer structure were successfully prepared for the first time using Yb-acetylacetone coordination polymer as a precursor. Thanks to the high ceramic yield (62.1%) and excellent spinnability of the precursor, the YbFMs exhibited outstanding flexibility, which does not cause damage even when bent or knotted. The tensile strength of the YbFMs was 1.69 MPa, and the maximum elongation could reach 33%. Notably, the YbFMs exhibited robust fatigue resistance, retaining 87.2% of the initial stress even after 500 buckling cycles and preserving 84.75% of the initial stress in compression resilience. Moreover, the YbFMs exhibited flexibility and compressive performance in the temperature range of −196− 1350 °C. The thermal conductivity of the YbFMs was 28.9−34.6 mW•m −1 •K −1 . At a hot surface temperature of 1350 °C, the 6 mm thick YbFMs could reduce the back temperature by about 1070 °C. Thus, YbFMs are expected to be a flexible insulation material at extremely high temperatures.

“…Such micro-/nanoparticles might aggregate in the environment or natural ecosystems during the detoxication process and it is implausible to recover the adsorbents again. 22 Hence, it is highly desirable to hybridize such catalytically active MOFs with protective modules, such as cartridge lters, 23 selfstanding polymeric membranes, 24,25 packed column beads, 26 and wearable garments with applications as an effective real-time ltration entity. 27 Among these, the development of catalytically active MOF-impregnated fabrics, in combination with air permeability, gives rise to the self-detoxifying ltration fabric.…”
