Abstract A novel biodegradable Mg‐4.0Zn‐1.0Ca‐0.6Zr (wt %) alloy was successfully produced using a series of metallurgical processes; including melting, casting, rolling, and heat treatment. The hardness ultimate tensile strength the sheets increased to 71.2HV 320 MPa after rolling then aging for 12 h at 175°C. These mechanical properties were sufficient load‐bearing orthopedic implants. hydroxyapatite (HA) coating deposited on process combining alkali pretreatment, electrodeposition,...
Two kinds of core–shell structured multifunctional nanocarriers gold nanoclusters (Au NCs) as core and folate (FA)-conjugated amphiphilic hyperbranched block copolymer shell based on poly(l-lactide) (PLA) inner arm FA-conjugated sulfated polysaccharide (GPPS–FA) outer NCs-PLA-GPPS-FA) were synthesized for targeted anticancer drug delivery. The structure properties Au NCs-PLA-GPPS-FA copolymers characterized determined by 1H NMR spectrum, FT-IR spectra, dynamic light scattering (DLS),...
Red-emitting fluorescent transferrin-functionalized copper nanoclusters were synthesized for the targeted bioimaging of HeLa cells.
Laser metal deposition (LMD) is one of the most important laser additive manufacturing processes. It can be used to produce functional coatings, repair damaged parts and manufacture components. Ti6Al4V commonly titanium alloys, since it features a good balance mechanical properties strength ductility. The LMD attracting more attention from both science engineering. interest in processing with industry, especially aerospace medical branches, has been increasing last few years. In this paper,...
Aluminum-magnesium (Al-Mg) alloys containing scandium (Sc) are high-performance lightweight materials. There is still limited research about the additive manufacturing of materials with powder-feeding-based laser metal deposition (LMD). This study aims to develop processing AA5024 (an Al-Mg alloy Sc) LMD. On this basis, TiC nano-particles added powder, in order seek an approach reduce need for Sc enhancing or adjust performance AA5024. Both pure powder and modified used build solid parts....
Zero- to two-dimensional nanomaterials have been incorporated into metal-matrices improve the strength of metals, but challengingly, high-volume-fraction are difficult disperse uniformly in metal matrices, severely degrading ductility conventionally processed metals. Here, a considerably dense uniform dispersion situ formed nanoscale lamellar TiC reinforcement (16.1 wt %) Ti matrix is achieved through laser-tailored 3D printing and complete reaction powder with small amount (1.0 carbon...
Porosity is a limiting factor in the processing of aluminum-alloys with Directed Energy Deposition (DED) and other Additive Manufacturing technologies, such as Laser Powder Bed Fusion. Especially mechanical properties additively manufactured samples are strongly dependent from porosity, thus, understanding parameters influencing porosity crucial. In this work, detailed study factors, which usually not considered but can affect AlMgScZr-alloy DED samples, presented. To end, influence powder...
Photobleaching effects of radiation-induced darkening in phosphosilicate Erbium-Ytterbium co-doped fibers with different laser wavelengths 532 nm, 633 and 1080 nm were studied. Both lasers exhibited photobleaching effects, which the showed superior performance. In contrast, did not exhibit any effect. The attenuation spectra continuous wave electron paramagnetic resonance fiber preform slices tested to analyze evolution P-related color center defects. influencing mechanisms discussed, a...
In the present study, ZnS and ZnO quantum dots (QDs) were synthesized via an all-aqueous process with polyethylene glycol (PEG) chains on their surface, toxicity as well biodistribution evaluated. No haemolysis occurred at a high concentration of 1600 µg/mL in vitro haemolytic assay, which demonstrated that QDs-PEG displayed good blood compatibility. Following intravenous administration 2, 6, 20 mg/kg mice, biodistribution, excretion biocompatibility characterized 1 h, 24 h 7 days,...
In this paper, we design and implement an applied wireless mesh network named MEMO with transparent client access support mobile node mobility management. Unlike traditional design, our proposed solution is based on MAC layer triggered mechanism special routing scheme called AODV_MEMO which combines management into a single solution. The advantages of AODV-MEMO include: (1) no modification required nodes; (2) accomplished in distributed way, central location server needed; (3) cross-...
Three trials were conducted to investigate the effect of RH (35, 60, and 85%) on thermoregulation 1-wk-old broiler chickens at different temperatures 30, 25 ° C). The response humidity in rectal temperature plumage back breast within 24 h after exposure recorded 5 time points (1,4,8,16, h). Humidity affected by redistributing heat body high, low, thermoneutral temperatures. redistribution resulted decreased increased peripheral temperature, which were, respectively, beneficial unfavorable...
Given an image, our proposed model can extract its dominant high-level semantics information through low-level feature extraction and image classification. It contains 3 main parts: segmentation, To knowledge, this is the first that applies Color Edge Directivity Descriptor (CEDD), a multiple algorithm, into field. Further, we also introduce new padding strategy for region representation, which especially suitable widely-used non-arbitrary over-segmentation. Finally, experiment shows CEDD...
Both 3D chromatin architecture and long non-coding RNAs (lncRNAs) play essential roles in pluripotency maintenance. However, whether lncRNAs are involved organizing structure remains largely unexplored. We identified 39 bound by Klf4, among which we further revealed the 5430416N02Rik promoter is a interaction hub. Knockout of locus reduces proliferation rate embryonic stem cells (ESCs). Moreover, deleting both gene body causes more severe defect has profound impact on transcriptome than...
The use of aluminium alloys containing Sc and Zr in additive manufacturing (AM) provides new solutions for lightweight design. Representative thin-wall structured parts were additively fabricated with a commercially available Al-4.55Mg-0.51Mn-0.65Sc-0.30Zr alloy Laser Metal Deposition (LMD) process. A bi-directional uni-directional scan strategy applied laser power from 500 W to 600 was used. Nanohardness tests conducted on specimens aged at 300 °C up 19 h observe the ageing responses....
Transcription factor Krüppel-like 5 (Klf5) plays important roles in the formation of inner cell mass (ICM) and trophectoderm during embryogenesis, as well self-renewal differentiation mouse embryonic stem cells (ESCs). Acetylation KLF5 has been shown to reverse transcriptional activity human epidermal prostate cancer cells. Whether Klf5 acetylation contributes lineage specification blastocyst pluripotency maintenance ESCs remains unexplored. Here, we showed ubiquitous expression acetylated...
Aluminum-magnesium-scandium-zirconium (AlMgScZr) alloys need to be rapidly cooled from the liquid state obtain a high degree of solute supersaturation that helps exploit precipitation hardening potential material. While AlMgScZr have been successfully used in laser powder bed fusion (LPBF) processes, there has little research field directed energy deposition (DED) The limited previous studies shown performance parts fabricated with DED only reached about 60% LPBF. In view breaking through...
