Dec 27, 2016 Ceramic biomaterials have been investigated for several decades, but their potential biomedical applications in cancer therapy have been paid much less attentions, mainly due to their lack of related material functionality for combating the cancer. In this work, we report, for the first time, that MAX ceramic biomaterials exhibit the unique functionality for the
Nov 09, 2021 The SiC-based ceramics with 15 wt% (Hf 0.2 Mo 0.2 Ta 0.2 Nb 0.2 Ti 0.2)B 2 showed the enhanced hardness (21.9 0.7 GPa) and high toughness (4.88 0.88 MPa m 1/2) as compared with high-entropy phase-free SiC-based ceramics, which exhibited a hardness of 16.6 GPa and toughness of 3.10 MPa m 1/2. The enhancement in mechanical properties was
Aug 01, 2021 Moreover, this ceramic shows a high electrical resistivity (ρ) of 1.35 10 8 Ω cm with a small dielectric loss (tan δ) of 1.7% at 400 C. Because of such outstanding piezoelectric performance, it is believed that these Sb–Mn co-doped CBT ceramics could be potential candidates for high-temperature piezoelectric applications
May 02, 2013 Nd:YAG transparent ceramics with different doping concentrations were fabricated by a solid‐state reaction method and vacuum sintering. Powder mixture of α‐Al 2 O 3, Y 2 O 3, and Nd 2 O 3 doped with tetraethoxysilane (TEOS) and MgO were sintered between 1500 o C and 1750 o C to examine the densification behavior in Nd:YAG ceramics. For the high
Oct 01, 2021 The coexisting of micropores, mesopores and macropores endow the AlN ceramics with a hierarchical porous structure. XRD patterns of AlN ceramics show that the main crystalline phase of the ceramic is AlN with a small amount of impurity peaks existing , indicating that a small amount of second phase (Y 3 A l5 O 12, white particles) is formed
The development of thermoelectric (TE) applications is promising due to great advances achieved in recent decades; however, some limitations still exist in the implementation of TE power generation due to its inferior conversion efficiency (η) compared with that of its competitors. Significantly, its low val Journal of Materials Chemistry A Recent Review Articles

The Great Yan Empire exists in a world where respect can only be earned through strength. Within this Great Yan Empire, the four great clans have always stood above the rest. Among them, a particular incident in the Lin Clan resulted in the banishment of a certain individual who went on to start his own family, in hopes of one day being recognized again by the Lin Clan
Abstract: Carbon/carbon(C/C) composites modified with SiCMoSi 2 coating are joined to Li 2 CO 3 Al 2 O 3 SiO 2 (LAS) glass ceramic using MgOAl 2 O 3 SiO 2 (MAS) glass. The effects of joining temperature, joining pressure, and holding time on the shear strength of the sample are studied. The optimal technological parameters obtained by orthogonal experiments are 1 200

An oscillating-plane lapping method, by which pre-sintered ceramic ball blanks are shaped before full sintering, was proposed to improve the precision of the ceramic ball blanks. For good sphercity and diameter consistency of ceramic ball blanks obtained after this shaping process, much less workmaterial is needed to be removed in the following lapping process of the full
