Zinc (Zn) has emerged as a promising biodegradable metal with moderate degradation profile and good biocompatibility. The wider application of Zn in clinics relies on further optimization its biodegradation behavior, biological activity, other functions. In recent years, various surface modification strategies have been applied to the orthopedics cardiovascular fields, significant progress made cytocompatibility, osteogenesis, antibacterial performance, control. this review, we summarized...
The prepared tea residue biochar loaded with Fe<sub>3</sub>O<sub>4</sub> has high-efficiency and environmental potential for activating peroxymonosulfate to degrade tetracycline hydrochloride.
Abstract The advent of additively manufactured biodegradable porous metals presents a transformative opportunity to meet the criteria ideal bone substitutes. Precisely tailoring their degradation behavior constitutes pivotal aspect this endeavor. In study, we investigated effects topological designs on profile laser powder bed fusion (LPBF) Zn scaffolds under dynamic in vitro immersion tests. Specifically, four types Zn-0.4Mn-0.2Mg (beam-based: diamond, face center cubic; surface-based:...
A new state-of-the-art thermoelectric material, Tl2Ag12Te7+δ, which possesses an extremely low thermal conductivity of about 0.25 W m–1 K–1 and a high figure-of-merit up to 1.1 at 525 K, was obtained using conventional solid-state reaction approach. Its subcell is variant the Zr2Fe12P7 type, but ultimately its structure refined as composite Tl2Ag12Te6 framework linear Te atom chain running along c axis. The super-space group determined be P63(00γ)s with = b 11.438(1) Å, 4.6256(5) that...
Zinc alloys have emerged as promising biodegradable metals thanks to their critical physiological roles and encouraging degradation behavior. In this study, calcium phosphate (CaP) coatings were made on micro-arc oxidized Zn alloy using hydrothermal treatment (HT), which was motivated by the CaP-based minerals in natural bone tissue. The coating morphology optimized controlling HT time, resulting a homogeneous micro-CaP structure. CaP significantly increased cell viability adhesion of...
Twitter's user behaviour data is crucial for studying patterns and content recommendation. To achieve this goal, the paper first preprocesses a Twitter dataset obtained from Kaggle. The includes over 40,000 objects in JSON format, focusing on users who tweeted trending topics had at least 100 followers were following other accounts. This filtering helps to exclude spam empty study constructs user-hashtag matrix applies label encoding technology convert it into numerical matrix. Thompson...
ABSTRACT Only one trip planner is needed for a group of friends to enjoy pleasant and only country coordinate on international talks that can be beneficial all participating countries. We study dynamic volunteering dilemma game in which two players choose volunteer or wait given there have not been any actions the past. The procrastinators benefits arrive later than costs. fully characterize stationary Markov Strotz‐Pollak equilibria. When cost sufficiently small agents' present‐bias...
While continuing our investigations of thallium chalcogenides because their outstanding thermoelectric properties, we discovered a new selenide with an interesting pnp switching behavior around 400 K. Tl2Ag12Se7 was prepared via high temperature reaction from the elements in stoichiometric ratio. This crystallizes structure type, namely √3 × 1 super cell Zr2Fe12P7 adopting space group P3̅, = b 18.9153(18) Å, c 4.3783(4) and V 1356.6(2) Å3 (Z 3). The consists complex network...
In this work, polycrystalline n-type Mg2Si0.30Sn0.67Bi0.03 dispersed with x wt % β-SiC nanoparticles (x = 0, 0.5, 1.0, 1.5, and 3.0) thermoelectric materials were fabricated by a solid-state reaction in low-cost container, consolidated hot-pressing. We obtained figure of merit values zT above 1.4 at 773 K along enhanced mechanical properties adding into an matrix. Incorporation SiC has thusly simultaneously increased toughness and, depending on the content, performance. The peak was improved...
Recent studies have indicated a great demand to optimize the biocompatibility properties of pure Zn as an implant material. For this purpose, CaZn2(PO4)2·2H2O (CaZnP) was prepared using hydrothermal treatment (HT) combined with micro-arc oxidation (MAO) on substrate generate biodegradable implants. The polarization test and electrochemical impedance spectroscopy that MAO1−HT coating could modulate corrosion behavior MAO1 by filling crevice between substrate. Immersion evaluation revealed...
