High-temperature infrared(IR)camouflage is crucial to the effective concealment of high-temperature objects but remains a challenging issue,as the thermal radiation of an object is proportional to the fourth power of temperature(T4).Here,we experimentally demonstrate high-temperature IR camouflage with efficient thermal *** combining a silica aerogel for thermal insulation and a Ge/ZnS multilayer wavelength-selective emitter for simultaneous radiative cooling(high emittance in the 5-8μm non-atmospheric window)and IR camouflage(low emittance in the 8-14μm atmospheric window),the surface temperature of an object is reduced from 873 to 410 *** IR camouflage is demonstrated by indoor/outdoor(with/without earthshine)radiation temperatures of 310/248 K for an object at 873/623 K and a 78% reduction in with-earthshine lock-on *** scheme may introduce opportunities for high-temperature thermal management and infrared signal processing.

Combinatorial therapies for spinal cord injury repair

引用

Neural Regeneration Research 2025年第5期20卷 1293-1308页

Spinal cord injuries have profound detrimental effects on individuals, regardless of whether they are caused by trauma or non-traumatic events. The compromised regeneration of the spinal cord is primarily attributed to damaged neurons, inhibitory molecules, dysfunctional immune response, and glial scarring. Unfortunately, currently, there are no effective treatments available that can fully repair the spinal cord and improve functional outcomes. Nevertheless, numerous pre-clinical approaches have been studied for spinal cord injury recovery, including using biomaterials, cells, drugs, or technological-based strategies. Combinatorial treatments, which target various aspects of spinal cord injury pathophysiology, have been extensively tested in the last decade. These approaches aim to synergistically enhance repair processes by addressing various obstacles faced during spinal cord regeneration. Thus, this review intends to provide scientists and clinicians with an overview of pre-clinical combinatorial approaches that have been developed toward the solution of spinal cord regeneration as well as update the current knowledge about spinal cord injury pathophysiology with an emphasis on the current clinical management.

Isospin Effect on Nuclear Stopping in Intermediate Energy Heavy Ion Collisions

引用

Chinese Physics Letters 2002年第3期19卷 321-323页

作者：李庆峰李祝霞 ChinaInstituteofAtomicEnergy P.O.Box275(18)Beijing102413

By using the isospin-dependent quantum molecular dynamics model, we study the dependence of nuclear stopping QZZ/A and R in intermediate energy heavy ion collisions on system size, initial N/Z, isospin symmetry potential and the medium correction of two-body cross sections. We find the effect of the initial N/Z ratio and isospin symmetry potential on stopping is weak. The excitation function of QZZ/A and R depends on the form of medium correction of two-body cross sections, the equation of state of nuclear matter. Our results show that the behaviour of the excitation function of QZZ/A and R can provide clearer information of the isospin dependence of the medium correction of two-body cross sections.
