Predictive value of thrombin–antithrombin III complex and tissue plasminogen activator–inhibitor complex biomarkers in assessing the severity of early‐stage acute pancreatitis

Chushu Liao, Guanghua Liu, Lingqian Li, Juan Wang, more

Journal of Gastroenterology and Hepatology > 39 > 10 > 2088 - 2096

Background and Aim The development of acute pancreatitis (AP) is strongly linked to blood clotting and fibrinolysis issues. Modern clinical practices now utilize advanced blood markers like thrombin–antithrombin III complex (TAT), plasmin‐α2‐plasmin inhibitor complex, thrombomodulin (TM), and tissue plasminogen activator–inhibitor complex (t‐PAIC) to assess thrombosis risk. Our study used a highly...

Fabrication of Si₃N₄ ceramics with improved thermal conductivity by carbothermal reduction and two‐step sintering

Binbin Fan, Zunlan Hu, Shuo Zhao, Dengke Zhao, more

Journal of the American Ceramic Society > 107 > 11 > 7319 - 7330

Si3N4 ceramics with improved thermal conductivity and mechanical properties were prepared by carbothermal reduction and two‐step sintering. The addition of 2 wt% C led to the development of an intergranular phase YNSiO2 with reduced oxygen content. Notably, setting the pre‐sintering temperature at 1450°C promoted the formation of a rough bimodal morphology within the Si3N4 ceramics. Furthermore, an...

Structure and property evolution of LaYbZr₂O₇/YSZ heterogeneous interface in double‐layer thermal barrier coatings after thermal exposure

Yang Lu, Jian Sun, Guanghua Liu, Wei Liu, more

Journal of the American Ceramic Society > 107 > 11 > 7253 - 7262

Double‐layer thermal barrier coatings are one of the development directions of thermal barrier coatings technology. LaYbZr₂O₇ (LYZO) has high toughness and low thermal conductivity, making it promising for use as a high‐temperature thermal barrier coating. However, its relatively poor mechanical properties, especially low fracture toughness, limit its further application. Therefore, we prepared a...

Bofeng Zhu, Kangxin Li, Jian Sun, Guanghua Liu, more

Journal of the American Ceramic Society > 107 > 11 > 7263 - 7273

The increase in operating temperature contributes to improving the performance and fuel utilization efficiency of gas turbines. However, it also places thermal barrier coatings (TBCs) in a more demanding working environment, requiring higher sintering resistance and better mechanical properties. In the present study, HfO₂ was introduced into the dual‐phase LaYbZr₂O₇ system as a doping oxide to form...

Highly dense α‐silicon nitride (Si₃N₄) ceramics were densified at a lower temperature of 1450°C under a moderate mechanical pressure of 50 MPa from commercial α‐Si₃N₄ powder and with conventional Al₂O₃–Y₂O₃ sintering additives. The fabricated α‐Si₃N₄ ceramics exhibited a hardness of 19 GPa, which is higher than that of the β‐Si₃N₄ ceramics usually obtained. The effect of sintering temperature and...

Journal of the American Ceramic Society > 107 > 4 > 2556 - 2564

Silicon nitride (Si₃N₄) ceramics with initial β‐Si₃N₄ content from 3% to 88% were prepared by spark plasma sintering from 1450 to 1700°C. The effect of initial β‐Si₃N₄ content on the phase transition, microstructure evolution, and mechanical properties of the Si₃N₄ ceramics was studied. The existence of initial β‐Si₃N₄ accelerated the α–β phase transition. When the initial β‐Si₃N₄ content was 12%...

Zhaobo Tian, Siyuan Sun, Songmo Du, Dengke Zhao, more

Journal of the American Ceramic Society > 106 > 10 > 5628 - 5634

Hexagonal boron nitride (h‐BN) has received considerable attention, due to its high thermal conductivity and electrical insulation. However, the intrinsic platelike structure with the strong anisotropic property restricts its applications, and it is necessary to synthesize isotropic spherical h‐BN particles (SP‐BNs) with submicron size. Till now, methods to prepare (SP‐BN) still exist problems, such...

Dimerized Nitrogen‐Annulated Perylene Synthesized from 1,6‐Diazecine as Chiral Emitter

Guiru Liu, Wenhao Zhang, Yao Xiao, Jing Cao, more

Chemistry – A European Journal > 29 > 19 > n/a - n/a

In this work, nitrogen‐annulated perylene (NP) was dimerized into one framework connected by two nitrogen atoms, generating the target molecule of DNP−DA. Owing to the substructure of 1,6‐diazecine ten‐membered ring, DNP−DA illustrates helical chirality with moderate dissymmetry factor, elevated molecular levels, expanded conjugation and supramolecular interactions with acceptors etc. Notably, DNP−DA...

Angewandte Chemie International Edition > 62 > 15 > n/a - n/a

A quadrupolar compound Pyr‐BA with two pyrrole‐type nitrogen atoms doped externally was prepared in this work. In high contrast with other π ionic radicals, its cationic radical Pyr‐BA⋅⁺ undergoes unusual symmetry‐broken charge separation (SB‐CS), generating the mixed valence complex of Pyr‐BA^+1−q⋅⋅⋅Pyr‐BA^+1+q, where q is the degree of charge transfer. Variable‐temperature (VT) single‐crystal analysis,...

Si₃N₄ powders were prepared by combustion synthesis with 1‐ and 3‐μm α‐Si₃N₄, β‐Si₃N₄ diluent and BN inert diluent. The maximum temperatures of samples with boron nitride (BN) as a diluent are about 1500–1600°C lower than that of samples with α‐Si₃N₄ and β‐Si₃N₄ as diluents are about 1600–1800°C. Moreover, the newly formed α‐Si₃N₄ contents in the synthesized products with BN as diluent over 90 wt%...

In situ combustion synthesis of spherical Si@Si₃N₄ granules

Jie Zhang, Fei Li, Liran Dong, Zhanglin Chen, more

Journal of the American Ceramic Society > 105 > 11 > 6529 - 6536

Spherical Si@Si₃N₄ granules were first prepared by in situ combustion synthesis. The inside of the granules is dense without cracks, and the two phases at the interface are well‐bonded. More significantly, no binder was used between the Si₃N₄ grains on the surface layer, thereby avoiding phonons scattering of metal oxides. In addition, crystallographic orientation relationships between Si and Si₃N...
