Abstract
Venous/arterial thrombosis poses significant threats to human health. However, drug-enabled thrombolysis treatment often encounters challenges such as short half-life and low bioavailability. To address these issues, the design of erythrocyte-membrane (EM) camouflaged nanocapsules (USIO/UK@EM) incorporating ultra-small iron oxide (USIO) and urokinase (UK) drug, which exhibits remarkable photothermal/magnetothermal effects and drug delivery ability for venous/arterial thrombolysis, is reported. USIO, UK, and EM are coextruded to fabricate USIO/UK@EM with average sizes of 103.7 nm. As USIO/UK@EM possesses wide photoabsorption and good magnetic properties, its solution demonstrates a temperature increase to 41.8-42.9 °C within 5 min when exposed to an 808 nm laser (0.33 mW cm-2) or alternating magnetic field (AMF). Such photothermal/magnetothermal effect along with UK confers impressive thrombolytic rates of 82.4% and 74.2%, higher than that (≈15%) achieved by UK alone. Further, the EM coating extends the circulating half-life (t1/2 = 3.28 h). When USIO/UK@EM is administered to mice and rabbits, tail vein thrombus in mice and femoral artery thrombus in rabbits can be dissolved by the synergetic effect of thermothrombolysis and UK. Therefore, this study not only offers insights into the rational design of multifunctional biomimetic nanocapsules but also showcases a promising thrombolysis strategy utilizing nanomedicine.

Abstract
The distinctive thermal energy storage properties of phase change materials (PCMs) are critical for solving energy issues. However, their inherently low thermal conductivity and limited energy conversion capability impede their applications in advanced thermal energy harvesting and storage systems. Herein, we developed magnetic composite PCMs with enhanced thermal conductivity for anisotropic photothermal and magnetic-to-thermal energy conversions. The hierarchically interconnected ferroferric oxide-coated boron nitride/poly(vinyl alcohol) (BN@Fe3O4/PVA) porous scaffolds were constructed by a unidirectional freeze-casting method to enhance the directional heat transfer capability of the composite PCMs with a through-plane thermal conductivity of 1.84 W m-1 K-1 at a BN@Fe3O4 loading of 25.4 wt %. The superparamagnetic Fe3O4 nanoparticles endow the composite PCMs with unique solar absorption and magnetic response properties, and the energy conversion efficiency can be regulated by controlling the orientation of the synthesized magnetic particles in the composite PCMs. As a consequence, the resulting composite PCMs exhibit superior photo/magnetic-to-thermal energy conversion efficiency along the direction of orientation of magnetic particles. These novel findings provide an instructive guide to yield composite PCMs for efficient energy conversion.

Abstract
As a minimally invasive heat source, radiofrequency (RF) ablation still encounters potential damages to the surrounding normal tissues because of heat diffusion, high power, and long time. With a comprehensive understanding of the current state of the art on RF ablation, a magnetic composite using porous hollow iron oxide nanoparticles (HIONs) as carriers to load dl-menthol (DLM) has been engineered. This composite involves two protocols for enhancing RF ablation, that is, HION-mediated magnetothermal conversion in RF field and RF solidoid vaporation (RSV)-augmented inertial cavitation, respectively. A combined effect based on two protocols is found to improve energy transformation, and further, along with hydrophobic DLM-impeded heat diffusion, improve the energy utilization efficiency and significantly facilitate ex vivo and in vivo RF ablation. More significantly, in vitro and in vivo RSV processes and RSV-augmented inertial cavitation for RF ablation can be monitored by T1-weighted magnetic resonance imaging (MRI) via an RF-sensitive longitudinal relaxation tuning strategy because the RSV process can deplete DLM and make HION carriers permeable to water molecules, consequently improving the longitudinal relaxation rate of HIONs and enhancing T1-weighted MRI. Therefore, this RF-sensitive magnetic composite holds a great potential in lowering the power and time of RF ablation and improving its therapeutic safety.

Abstract
A novel magnetic hydrogel is formed via the field-directed assembly of magnetic nanomaterials during the gelation process. The novel magnetic hydrogel exhibits direction-dependent thermogenesis in an alternating magnetic field. The specific absorption rate value in the direction along the assemblies can be 2.1-fold as much as that in the direction normal to the assemblies while the heating rate is 6-8-fold. Due to the anisotropic thermogenesis, the novel magnetic hydrogel also shows a direction-dependent release of drugs that has a 3.4-fold difference between the two directions.

Abstract
The presence of a quantum-critical point (QCP) can significantly affect the thermodynamic properties of a material at finite temperatures T . This is reflected, e.g., in the entropy landscape S (T ,r ) in the vicinity of a QCP, yielding particularly strong variations for varying the tuning parameter r such as pressure or magnetic field B . Here we report on the determination of the critical enhancement of ∂S /∂B near a B -induced QCP via absolute measurements of the magnetocaloric effect (MCE), (∂T /∂B )S and demonstrate that the accumulation of entropy around the QCP can be used for efficient low-temperature magnetic cooling. Our proof of principle is based on measurements and theoretical calculations of the MCE and the cooling performance for a Cu2+-containing coordination polymer, which is a very good realization of a spin-½ antiferromagnetic Heisenberg chain—one of the simplest quantum-critical systems.
