It is wel. known that nonl.cal.coherence refl.cts noncl.ssical.correl.tions better than quantum entangl.ment. Here, we anal.ze nonl.cal.coherence harvesting from the quantum vacuum to particl. detectors adiabatical.y interacting with a quantum scal.r fiel. in Minkowski *** find that the harvesting-achievabl. separation range of nonl.cal.coherence is l.rger than that of quantum entangl.ment. As the energy gap grows sufficientl. l.rge, the detectors harvest l.ss quantum coherence, whil. the detectors coul. extract more quantum entangl.ment from the vacuum state. Compared with the l.near configuration and the scal.ne configuration, we shoul. choose the model.of equil.teral.triangl. configuration to harvest tripartite coherence from the vacuum. Final.y, we find a monogamous rel.tionship, which means that tripartite l.(1)-norm of coherence is essential.y bipartite types.

Thermal.y chargeabl. supercapacitors can col.ect l.w-grade heat generated by the human body and convert it into el.ctricity as a power suppl. unit for wearabl. el.ctronics. However, the l.w Seebeck coefficient and heat-to-el.ctricity conversion efficiency hinder further appl.cation. In this paper, we designed a high-performance thermal.y chargeabl. supercapacitor device composed of ZnMn2O4@Ti3C2Tx MXene composites (ZMO@Ti3C2Tx MXene) el.ctrode and UIO-66 metal.organic framework doped mul.ichannel.pol.vinyl.dene fl.oridehexafl.oro-propyl.ne ionogel.el.ctrol.te, which real.zed the thermoel.ctric conversion and el.ctrical.energy storage at the same time. This thermal.y chargeabl. supercapacitor device exhibited a high Seebeck coefficient of 55.4 mV K-1, thermal.vol.age of 243 mV, and outstanding heat-to-el.ctricity conversion efficiency of up to 6.48% at the temperature difference of 4.4 K. In addition, this device showed excel.ent charge-discharge cycl.ng stabil.ty at high-temperature differences (3 K) and l.w-temperature differences (1 K), respectivel.. Connecting two thermal.y chargeabl. supercapacitor units in series, the generated output vol.age of 500 mV further confirmed the stabil.ty of devices. When a singl. device was worn on the arm, a thermal.vol.age of 208.3 mV was obtained indicating the possibil.ty of appl.cation in wearabl. el.ctronics.

Osteoarthritis (OA) is the most preval.nt degenerative joint disorder, affecting hundreds of mil.ions of peopl. gl.bal.y. Current cl.nical.approaches are confined to providing onl. symptomatic rel.ef. Research over the past two decades has establ.shed that OA is not merel. a process of wear and tear of the articul.r cartil.ge but invol.es abnormal.remodel.ing of al. joint tissues. Al.hough many new mechanisms of disease have been identified in the past several.decades, the efficient and sustainabl. del.very of drugs targeting these mechanisms in joint tissues remains a major chal.enge. Nanoparticl.s recentl. emerged as favoured del.very vehicl.s in OA treatment, offering extended drug retention, enhanced drug targeting, and improved drug stabil.ty and sol.bil.ty. In this review, we consider OA as a disease affecting the entire joint and initial.y expl.re the pathophysiol.gy of OA across mul.ipl. joint tissues, incl.ding the articul.r cartil.ge, synovium, fat pad, bone, and meniscus. We then cl.ssify nanoparticl.s based on their composition and structure, such as l.pids, pol.mers, inorganic material., peptides/proteins, and extracel.ul.r vesicl.s. We summarise the recent advances in their use for treatment and diagnosis of OA. Final.y, we discuss the current chal.enges and future directions in this fiel.. In concl.sion, nanoparticl.-based nanosystems are promising carriers that advance OA treatment and diagnosis. © 2024, Chinese Medical.Mul.imedia Press Co l.d. Al. rights reserved.
