乳脂肪球起源于乳腺上皮细胞,脂肪球膜中的脂质和蛋白质通过静电斥力和空间位阻维持脂肪球的稳定性,同时膜上的成分具有特定的营养特性。脂肪球界面的重新构建对液态乳制品的品质至关重要,本文对近年来加工中乳脂肪球界面构建机制的研究进行总结并发掘共通之处。均质会破坏脂肪球膜的原生结构,导致膜结构重新排列。此外,热处理也会改变蛋白质的结构,并引起脂质结构域的侧向分离。同时,脂肪球膜上蛋白质和脂质的热响应会导致原始膜成分的损失。外源添加物通过改善油水界面和增强脂肪球的稳定性,参与体系稳定化的重构建。未来需深入研究脂肪球膜构建机制与宏观体系的联系,并优化特定的加工条件,以获得更高品质的乳制品。

The hierarchical porous N/O co-functionalized carbon(HPNOC)was scalably prepared by using the lowcost and renewable blighted grains as the raw material coupled with mild KHCO_3 activation for electrochemical capacitors(ECs).The elemental N was in situ doped in the obtained HPNOC without any N-containing ***,the obtained HPNOC was endowed with a large specific surface area(about 2 624m^2·g^(-1)),high pore volume(about 1.35cm^3·g^(-1)),as well as high-content N/O functionalization(about 1.9%(in atom)N and about 10.2%(in atom)***,the as-resulted HPNOC electrode with a high mass loading of 5mg·cm^(-2 )exhibited competitive gravimetric capacitances of about 373.6F·g^(-1 )at 0.5A·g^(-1),and even about 260.4F·g^(-1 )at a high rate of 10A·g^(-1);superior capacitance retention of about 98.8%at 1A·g^(-1 )over 10 000consecutive cycles;and high specific energy of about 9.6W·h·kg^(-1 )at a power of 500W·kg^(-1),when evaluated as a promising electrode in 6mol KOH for advanced electrochemical *** encouragingly,the green synthetic strategy we developed holds a huge promise in generalizing for other biomass-derived carbon materials for versatile energy-related applications.

全球慢性病患病率不断上升,给社会的发展和个人健康带来重大挑战。管理慢性病需要长期治疗和监测,对患者的生活方式提出了一定要求。随着人口老龄化和人们生活方式的改变,慢性病防控正变得越发重要。近年来,随着医疗卫生领域科技创新向纵深发展,借助人工智能的智能机器人在医疗领域的应用也逐渐成为国家重要战略方向之一,传统的慢性病管理方法过于依赖医生和患者之间的线下交流,导致医生无法与患者保持长期且有效的沟通和随访,患者病情出现变化时医生可能无法及时发现和监测。此外,传统的慢性病管理方法通常是一种通用化的方法,无法充分考量到每位患者的个体差异。鉴于传统慢性病管理方法的局限性,本文提倡利用智能机器人提供更便捷高效的基层服务。本文认为,通过个性化健康管理方案、辅助医疗诊断、定时提醒服药等功能,使智能机器人能够致力于改善患者生活质量、减轻医疗资源压力,从而推动全球智能化医疗管理的发展。

Tin monosulfide(Sn S), which is composed of earth-abundant elements, holds promise as useful high-performance solar absorber and thermoelectric material. In addition to the ground-state Pnma phase, a series of metastable phases in different crystalline structures have been reported experimentally or theoretically, yet the phase stability diagrams remain elusive. In this article, we provide a comprehensive materials design study of new phases of Sn S using first-principles global optimization structure search calculations. We find that the two-dimensional layered phases are generally more energetically favored than the three-dimensional connected phases. In addition, we discover several new phases with comparable energetics. Four lower-energy phases show clear phonon stabilities evidenced by an absence of imaginary modes. The electronic band structures, carrier transport properties, and absorption spectra of the newly discovered phases are investigated and discussed toward potential applications for solar cells and thermoelectric devices.

Viscoelasticity and poroelasticity commonly coexist as time-dependent behaviors in polymer gels. Engineering applications often require knowledge of both behaviors separated; however, few methods exist to decouple viscoelastic and poroelastic properties of gels. We propose a method capable of separating viscoelasticity and poroelasticity of gels in various mechanical tests. The viscoelastic char- acteristic time and the poroelastic diffusivity of a gel define an intrinsic material length scale of the gel. The experimen- tal setup gives a sample length scale, over which the solvent migrates in the gel. By setting the sample length to be much larger or smaller than the material length, the viscoelasticity and poroelasticity of the gel will dominate at different time scales in a test. Therefore, the viscoelastic and poroelastic properties of the gel can be probed separately at different time scales of the test. We further validate the method by finite-element models and stress-relaxation experiments.
