Optical behavior of Eu2+and Yb2+ doped alkaline earth metatitanate perovskite phosphors

A complete investigation of optical and spectral behavior of Eu2+ and Yb2+ activated ATiO3 (A = Ca, Ba, Sr) alkaline earth metatitanates perovskites phosphors synthesized via conventional solid state reaction technique is done here. The crystallographic analysis show crystalline structure with high phase purity and homogeneity in the synthesized phosphors. The FESEM analysis shows formation of porous globular particles with irregular shape, uniform grain connectivity and variable dimensions in the synthesized phosphors. The TEM micrographs also confirm the irregularity of particle shape along with agglomeration. The functional group analyses done under FTIR spectroscopy set forth the fingerprints of various molecular activities in the phosphors. The PL emission spectra monitored at λ = 230 nm for CaTiO3 :Eu2+,Yb2+, λ = 227 nm for BaTiO3 :Eu2+,Yb2+ and λ = 225 nm for SrTiO3 :Eu2+,Yb2+ phosphors show distinct line emissions at 482 nm, 495 nm, 545 nm, 595 nm and 620 nm attributing to characteristic hypersensitive transitions of Eu2+ (4f-5d) and Yb2+ ions (5d-4f) ions. The chromaticity coordinates were computed and plotted in the two dimensional CIE gamut chart to study the color tunability of the synthesized phosphors. The enhancement in the optical emissions and improved quantum yields were studied in detail under photoluminescent spectroscopy.

A Femtoliter Droplet Array for Massively Parallel Protein Synthesis from Single DNA Molecules.

Advances in spatial resolution and detection sensitivity of scientific instrumentation make it possible to apply small reactors for biological and chemical research. To meet the demand for high-performance microreactors, we developed a femtoliter droplet array (FemDA) device and exemplified its application in massively parallel cell-free protein synthesis (CFPS) reactions. Over one million uniform droplets were readily generated within a finger-sized area using a two-step oil-sealing protocol. Every droplet was anchored in a femtoliter microchamber composed of a hydrophilic bottom and a hydrophobic sidewall. The hybrid hydrophilic-in-hydrophobic structure and the dedicated sealing oils and surfactants are crucial for stably retaining the femtoliter aqueous solution in the femtoliter space without evaporation loss. The femtoliter configuration and the simple structure of the FemDA device allowed minimal reagent consumption. The uniform dimension of the droplet reactors made large-scale quantitative and time-course measurements convincing and reliable. The FemDA technology correlated the protein yield of the CFPS reaction with the number of DNA molecules in each droplet. We streamlined the procedures about the microfabrication of the device, the formation of the femtoliter droplets, and the acquisition and analysis of the microscopic image data. The detailed protocol with the optimized low running cost makes the FemDA technology accessible to everyone who has standard cleanroom facilities and a conventional fluorescence microscope in their own place.

Simple Controlling Ecofriendly Synthesis of Silver Nanoparticles at Room Temperature Using Lemon Juice Extract and Commercial Rice Vinegar

Silver nanoparticles were prepared in an ecofriendly manner at room temperature via the stepwise-modified Tollens route using the lemon juice extract and commercial rice vinegar. In this work, the lemon juice extract—a natural-origin chemical—was used as a reducing and stabilizing agent, and commercial rice vinegar was used to create a low acidic environment to control the silver nanoparticle growth via the stepwise method. The average dimension of silver nanoparticles was qualitatively evaluated through the UV-Vis spectra via the Mie theory. The X-ray diffraction and field emission scanning electron spectroscopy were employed to study the purity, the crystal structure, and the morphology of samples, respectively. Due to the weak activity and low purity of ecofriendly chemicals, the reaction and baking times strongly affect the preparation efficiency in obtaining small-size silver nanoparticles (∼40 nm). The highest efficiency was obtained with 24 h reaction time and 48 h baking time. The bimodal distribution of the size of silver nanoparticles was observed by UV-Vis analysis and field emission scanning electron microscopy. The obtained small-size silver nanoparticles (∼40 nm) have a uniform dimension. The quality of the obtained silver nanoparticles was evaluated through the conducting properties of silver paint made from ecosynthesized silver nanoparticles which showed a promising prospect to develop green-synthesized silver paint working at room temperature.

Nonlinear acoustic crack detection in thermoelectric wafers

An acoustic technique for detecting cracks in bismuth telluride (Bi2Te3) thermoelectric wafers is presented. The technique is based on mechanically exciting the wafers with a low frequency pump signal that drives a crack to “breathe” by opening and closing periodically and a high frequency probe signal that interrogates the breathing crack. Interaction between the pump signal, the probe signal, and the crack leads to generation of acoustic nonlinearities in the wafer. In contrast to existing acoustic crack detection techniques we utilize standing waves within the wafers to facilitate simultaneous crack detection throughout the wafer, which reduces the total inspection time; we do not require uniform dimensions and material properties between wafers; and we do not affix the transmitter/receiver to the wafers, which can lead to wafer damage. We present a technique that integrates multiple damage metrics to identify cracks within the wafers. We demonstrate the technique on 94 Bi2Te3 wafers, of which we correctly identify cracked wafers with 4.3% total error and we correctly identify crack-free wafers with 7.5% total error. This acoustic crack detection technique finds application in manufacturing of thermoelectric wafers and other materials, where identifying cracks early in the manufacturing process results in significant time and cost savings. Additionally, this acoustic crack detection technique has implications for other nondestructive inspection applications where cracks cannot be detected effectively through existing techniques.

Comparison of shear bond strength of light cure mineral trioxide aggregate and light cure calcium hydroxide with nanofilled composite: A stereomicroscopic and scanning electron microscope analysis.

The quest for ideal pulp capping materials has given rise to the development of newer materials such as light cure mineral trioxide aggregate (MTA). The bond strength of the pulp capping materials with overlying restoration is one among the several factors that are critical for the success of vital pulp therapy. Hence, we conducted this study to evaluate and compare the shear bond strength (SBS) of light cure MTA and light cure calcium hydroxide with nanofilled composite. Thirty acrylic blocks each with a central hole were prepared to uniform dimensions and randomly distributed into two equal groups. In Group I, light cure MTA, and in Group II, light cure calcium hydroxide was used as pulp capping materials. After the application of adhesive system, nanofilled composites were applied onto the pulp capping material using a cylindrical plastic matrix. The SBS was tested on a universal testing machine (Instrom 3366, UK) at a crosshead speed of 0.5 mm/min. The samples were examined under stereomicroscope and scanning electron microscope to analyze different modes of failure. The results were statistically analyzed using independent sample t-test. Light cure MTA attained the mean SBS of 6.54 MPa and light cure calcium hydroxide attained the mean SBS of 6.56 MPa. There was no significant difference statistically in SBS of both the materials (P < 0.05). The modes of failure were predominantly mixed failure followed by cohesive failure within the restorative material in both Group I and II. The results of the study suggest that the SBS of light cure MTA and light cure calcium hydroxide is comparable. The modes of failure analyzed in both light cure MTA and light cure calcium hydroxide are not significantly different statistically. Hence, both materials can be successfully used as pulp capping material with nanofilled composite.

Purpose: The aim of this study was to assess and evaluate the retention of conventional retentive sleeve material versus retention.sil in implant-retained overdentures.Methodology: Custom-designed models of uniform dimensions were made from heat-polymerized polymethyl methacrylate resin. The model had two components which comprised a lower member (matrix) and an upper member (patrix). The lower member (matrix) was embedded with two ADIN implant analogs attachment (Adin Implant System Ltd. Israel) of 3.75 mm × 10 mm with prefabricated ball attachment at an interimplant distance of 20 mm. The upper member was prepared to receive two different retention sleeve materials, conventional retentive/plastic sleeve attachment (Adin Implant System Ltd. Israel), and retention.sil 600 (Bredent medical GmbH and Co. KG). Using a universal testing machine, each of the models was subjected to 100 pulls each to dislodge the upper member from the lower member, and the force values as indicated on the digital indicator were tabulated.Statistical Analysis Used: Statistical analysis comprised Kolmogorov–Smirnov test, Friedman test, Mann–Whitney test, and Wilcoxon signed-rank test.Results: The statistical model revealed that when subjected to vertically directed forces, the conventional retentive/plastic sleeve attachment (Adin Implant System Ltd. Israel) developed higher retentive force as compared to the retention.sil 600 (Bredent medical GmbH and Co. KG).Conclusions: The conventional retentive sleeve material maintains their retentive capacity longer than the retention.sil 600. Further research is required to increase the retentive force in retention.sil material, thereby increasing denture retention and stability.

An Examination on Queuing Classification in Non-Destructive Testing

Nondestructive testing (NDT) is the way toward assessing, testing, or assessing materials, segments or gatherings for discontinuities, or contrasts in attributes without pulverizing the usefulness of the part or framework. Today current nondestructive tests are utilized in assembling, creation and in-administration investigations to guarantee item uprightness and unwavering quality, to control fabricating forms, lower generation costs and to keep up a uniform quality dimension. Amid development, NDT is utilized to guarantee the nature of materials and joining forms amid the manufacture and erection stages, and in-administration. NDT assessments are utilized to guarantee that the items being used keep on having the honesty important to guarantee their value and the security of the general population .Test strategy names regularly allude to the kind of entering medium or the hardware used to play out that test. One of the every now and again utilized test techniques is Liquid infiltrating test. The procedure is carried out in such a way that, to begin with, the penetrant is connected on the specimen which is to be tried, next the utilization of developer is done. In any case, before this designer procedure, there is a delay where other distractive procedure to be discounted. Next after the developer procedure, the procedure is rehashed if the aftereffect of the item isn't true to form. Following, maintenance work, for example, pre cleaning process like showering, brushing, inundating and so on is done. At last if in need another primer nondestructive test is additionally done for the item got. The above procedure is totally changed into a Queuing procedure in which the issue is all around concentrated by hypothesis of lining and it is illuminated by beneficial variable strategy. By the utilization of the above strategy, all the presentation proportions of the line in this procedure can be determined. Numerical delineation and graphical portrayal still amplify the model to a great extent.

Process planning strategy for wire-arc additive manufacturing: Thermal behavior considerations

Wire arc additive manufacturing (WAAM) has become a promising metal 3D printing technology for fabricating large-scale and complex-shaped components. One major problem that limits the application of WAAM is the difficulty in controlling the dimensional accuracy under constantly changing interlayer temperatures. During the deposition process, as the wall height increases, the heat accumulates on the upper layers, which leads to the variation of the layer dimensions. Normal practices such as introducing idle time and actively cooling the workpiece to mitigate such problems lack efficiency and practicality, respectively. A novel process planning strategy is proposed in this paper and aims to achieve a continuous deposition process while ensuring dimensional accuracy. With the aid of a finite element model, the typical thermal transfer cycle of the workpiece was analyzed and then divided into different stages. When depositing material, the interlayer temperature of the subsequent layers can be predicted using the developed algorithm. Hence, the process parameters (e.g., wire feed speed and travel speed) can be varied according to the predicted interlayer temperature using the developed adaptive process model, and this will ensure the uniform layer dimensions. The effectiveness of the proposed technique is verified by a large-scale shell-shaped component with a total of 753 layers. The result shows that such technique succeeds in a continuous fabrication of the component with high accuracy and efficiency.

Seaweed biomass waste-derived carbon as an electrode material for supercapacitor

Seaweed fibre is usually discarded as biomass waste after extraction of useful ingredients from seaweed. However this seaweed fibre, a natural abundant cellulose material with uniform dimensions 10 times smaller than other plant-based fibre can be utilized as electrode material for energy storage. In this work, we converted seaweed fibre into conductive carbon electrodes by a thermal carbonisation method. The morphology, chemical composition and conductivity are highly influenced by the carbonisation temperature. In comparison to other biomass sources such as cotton pulp, seaweed fibre is finer, smoother and more conductive at low carbonisation temperature. These carbonized seaweeds were then used as a supercapacitor, giving a high supercapacitance (226.3 Fg−1) at the carbonisation temperature of 900°C, and good stability within 2400 cycles. This specific capacitance is significantly higher than values obtained from filter paper or cotton pulp.

Uniform Dimension Results for the Inverse Images of Symmetric Lévy Processes

We prove uniform Hausdorff and packing dimension results for the inverse images of a large class of real-valued symmetric L\'evy processes. Our main result for the Hausdorff dimension extends that of Kaufman (1985) for Brownian motion and that of Song, Xiao, and Yang (2018) for $\alpha$-stable L\'evy processes with $1<\alpha<2$. Along the way, we also prove an upper bound for the uniform modulus of continuity of the local times of these processes.

On the modeling of heavy metals and rare earth elements adsorption on colloidal carbon-based nanoparticles

Acid-base and metal ions adsorptive properties of colloidal carbon-based nanostructured materials, bearing a variable number of oxygen-containing functional groups at the surface, were investigated and modeled. Hydrophilic carbonaceous nanoparticles (HNPs) with uniform dimensions and a good grade of dispersion in water, were obtained through the oxidation of a carbon black with nitric acid, at a temperature of 100 °C, for different reaction times (2–24 h). The acid-base properties of the functional groups were evaluated in water suspension by potentiometry and infrared spectroscopy. By means of X-ray fluorescence, infrared spectroscopy and differential pulse voltammetry the interaction properties of HNPs with Cd2+, Zn2+, Pb2+ and selected Ln3+ ions have also been investigated. The experimental data, collected in the 2.0–7.0 pH range, suggest that the adsorption of metal ions on HNPs is controlled by chemical adsorption involving the strong complexation of metal ions with the carboxylic groups on the surface of HNPs. Particularly, the high complexation of Ln3+ ions opens the exploitation of HNPs in solid phase extraction for preconcentration, separation and determination of rare earth elements and actinides.

Uniform Biodegradable Fiber-Like Micelles and Block Comicelles via "Living" Crystallization-Driven Self-Assembly of Poly(l-lactide) Block Copolymers: The Importance of Reducing Unimer Self-Nucleation via Hydrogen Bond Disruption.

Fiber-like micelles based on biodegradable and biocompatible polymers exhibit considerable promise for applications in nanomedicine, but until recently no convenient methods were available to prepare samples with uniform and controllable dimensions and spatial control of functionality. "Living" crystallization-driven self-assembly (CDSA) is a seeded growth method of growing importance for the preparation of uniform 1D and 2D core-shell nanoparticles from a range of crystallizable polymeric amphiphiles. However, in the case of poly(l-lactide) (PLLA), arguably the most widely utilized biodegradable polymer as the crystallizable core-forming block, the controlled formation of uniform fiber-like structures over a substantial range of lengths by "living" CDSA has been a major challenge. Herein, we demonstrate that via simple modulation of the solvent conditions via the addition of trifluoroethanol (TFE), DMSO, DMF and acetone, uniform fiber-like nanoparticles from PLLA diblock copolymers with controlled lengths up to 1 μm can be prepared. The probable mechanism involves improved unimer solvation by a reduction of hydrogen bonding interactions among PLLA chains. We provide evidence that this minimizes undesirable unimer aggregation which otherwise favors self-nucleation that competes with epitaxial crystallization from seed termini. This approach has also allowed the formation of well-defined segmented block comicelles with PLLA cores via the sequential seeded-growth of PLLA block copolymers with different corona-forming blocks.

Supramolecular Hexagonal Platelet Assemblies with Uniform and Precisely-Controlled Dimensions.

Geometric structures are commonly encountered in natural and designed systems. However, the bottom-up fabrication of regular geometric assemblies with precise dimensional control, especially from soft materials, poses an outstanding challenge in contemporary materials science and chemistry. Herein, we present a general method for the preparation of colloidally stable, hexagonal platelets via the formation of crystalline inclusion complexes of tris-o-phenylenedioxycyclotriphosphazene and block copolymers bearing interactive blocks. Dictated by the screw dislocation growth of inclusion complexes, uniform hexagonal platelets with precisely controllable dimensions can be prepared. This supramolecular assembly approach is further utilized to produce concentric hexagonal platelets via stepwise seeded growth from various inclusion complexes.

МЕТОДИКА ОЦІНЮВАННЯ ЕФЕКТИВНОСТІ ФУНКЦІОНУВАННЯ ЛІНІЇ ЗВ’ЯЗКУ

The article deals with the actual issue of improving the scientific and methodical apparatus for evaluating the effectiveness of the digital communication line. Recent researches and publications on this issue have been analyzed. The analysis shows that these methods can not provide a sufficient level of accuracy and objectivity of the assessment due to the failure to take into account the experience of using communication lines during the operation and some factors that significantly influence the efficiency of digital lines functioning in these conditions. Another methodological approach for solving the applied problem is considered in the article. The application of the method of vector estimation of the efficiency indicator is proposed. The determined integral indicator of efficiency and the criterion for evaluating the effectiveness of the digital line for solving the problem. The relationships for estimating external and internal factors and their influence on the efficiency of digital communication line operation are presented. The proposed method gives an opportunity to obtain a more objective and adequate assessment of the efficiency of the communication line. The application of this method of vector estimation of efficiency eliminates the need to solve a problematic issue, which consists in the normalization of the components of the evaluation criterion, bringing to uniform dimensions and scales, their ranking or assigning weight coefficients, and also convolutions of individual components, which makes it possible to use the method described in the article for problems evaluation of the efficiency of different kind of lines and communication networks.

Fractional excitations in one-dimensional fermionic systems

We study the soliton modes carrying fractional quantum numbers in one-dimensional fermionic systems. In particular, we consider the solitons in the one-dimensional fermionic superfluids. For the s-wave order parameter with phase twisted by an angle φ, the complex Z2 soliton may occur carrying a localized fractional quantum number φ/(2π). If the system is finite with length L, we show the existence of a uniform background −φ/(2πL) which, though vanishing in the thermodynamic limit, is essential to maintain the conservation of the total integer quantum number. This analysis is also applicable to other systems with fractional quantum numbers, thus providing a mechanism to understand the compatibility of the emergence of fractional quantum number in the thermodynamic limit of a finite system with only integer quantum numbers. For the p-wave pairing case, the Majorana zero mode may occur associated with a real Z2 soliton, and the fractionalized quantum number is the dimension of the single particle Hilbert space, which turns out to be 1/2. Again for a finite system with length L, there is an accompanying uniform dimension density −1/(2L) to maintain the dimension of the Hilbert space invariant. We conjecture a connection of the dimension density of one-dimensional solitons with the quantum dimension of topological excitations.

Self-Assembled Dual Helical Nanofibers of Amphiphilic Perylene Diimides with Oligopeptide Substitution.

We designed an asymmetric amphiphilic perylene diimide (PDI) with the oligopeptide substituting one of the imides. The self-assembly mechanism of this PDI in different solvents was investigated. Right-handed "dual" helical nanofibers/nanowires with a uniform lateral dimension of ∼8 nm are constructively self-assembled. The long-term ordered degree within the nanofibers stems from the delicate balance between π-π stacking of the PDI rings and β-sheet-like hydrogen bond formed by the oligopeptide. The synergistic interplay between the hydrogen bond and π-π stacking rather than competition endows the nanofibers with the controllable longitudinal dimensions by different factors such as the concentration and solvents. The transition from the nanofibers to the small aggregates is also achieved by the addition of trifluoroacetic acid because of breakup of the hydrogen bonds, which is reversed by further addition of trimethylamine. The acid-base stimulation can be extended to different solvents as long as the existence of the unique hydrogen bonds.

Amorphous Manganese Dioxide Coated Polydopamine Nanoparticles for Acid-Sensitive Magnetic Resonance Imaging-Guided Tumor Photothermal Therapy.

Photothermal therapy (PTT) is a powerful technique for tumor ablation. However, there is a problem that PTT cannot accurately locate the tumor site, so it is easy to cause heat damage to the surrounding normal tissues. In this study, PEGylated amorphous manganese dioxide (MnO₂) coated polydopamine (PDA) core-shell nanoparticles (PDA@MnO₂-PEG) with regular morphology and uniform dimensions were prepared for acid-sensitive magnetic resonance imaging-guided tumor photothermal therapy. The results showed that amorphous MnO₂ shell provided markedly acid-sensitive T1-weighted magnetic resonance imaging (MRI). The relaxation rate (r1 value) of PDA@MnO₂-PEG in pH=7.4 was measured to be 0.310 mM-1·S-1, while that in pH=6 became 4.364 mM-1·S-1. In mice tumor models, MRI of tumors exhibited dramatically whitening effects compared with the signal before injection. Besides, the in vivo experiments revealed that the tumors in PTT group with PDA@MnO₂-PEG injection and NIR laser irradiation were almost eliminated within 14 days, indicating the effective photothermal therapy of tumor generated by the PDA core. In conclusion, we successfully synthesized amorphous MnO₂ coated PDA core-shell nanoparticles with the function of acid-sensitive magnetic resonance imaging guided photothermal therapy, which provide a new approach for improving the effect of photothermal therapy of tumors.

On C-co-epi-retractable Modules

In this paper, we introduce the notion of c-co-epi-retractable modules. An R-module M is called c-co-epi-retractable if it contains a copy of its factor module by a complement submodule. The ring R is called c-co-pri if RR is c-co-epi-retractable. Conditions are found under which, a c-coepi-retractable module is extending, retractable, semi-simple, quasi-injective, injective and simple. Also, we investigate when c-co-epi-retractable modules have finite uniform dimension. Finally, right SI-rings, semi-simple artinian rings and quasi-Frobenius rings are characterized in termes of c-co-epi-retractable modules.

Analysis of polymeric materials properties changes after addition of reinforcing fibers

Purpose The issues concerning the prediction of changes in properties of polymer materials as a result of adding reinforcing fibers are currently widely discussed in the field of polymer material processing. This paper aims to present strengths and weaknesses of composites based on polymer materials strengthened with fibers. It touches upon composite cracking at the junction of a matrix and its reinforcement. It also discusses the analysis of changes in properties of chosen materials as a result of adding reinforcing fibers. The paper shows improvement in the strength of polymer materials with fiber addition, which is extremely important, because these types of composites are used in the aerospace, automotive and electrical engineering industries. Design/methodology/approach Comparing the properties of matrix strength with fiber properties is practically impossible. Thus, fiber tensile strength and composite tensile strength shall be compared (González et al., 2011): tensile (glass fiber GF) = 900 [MPa], elongation ΔL≈ 0; yield point (polyamide 66) = 70−90 [MPa], elongation Δ[%] = 3,5-18; tensile (polyamide 66 + 15% GF) = 80-125 [MPa], elongation Δ[%] ≈ 0; tensile (polyamide 66 + 30% GF) = 190 [MPa], elongation Δ[%] ≈ 0; yield point (polyamide 6) = 45-85 [MPa], elongation Δ[%] = 4-15; tensile (polyamide 6 + 15% GF) = 80-125 [MPa], elongation Δ[%] ≈ 0; tensile (polyamide 6 + 30% GF) = 95-130 [MPa] elongation Δ[%] ≈ 0. Comparison of properties of selected polymers and composites is presented in Tables 1−10 and Figures 1 and 2. The measurement methodology is presented in detail in the paper Kula et al. (2018). The increase in fiber content (to the extent discussed) leads to the increase in yield strength stresses and hardness. The value of yield strength for polyamide with the addition of fiberglass grows gradually with the increase in fiber content. The hardness of the composite of polyamide with glass balls increases together with the increase in reinforcement content. The changes of these values do not occur linearly. The increase in fiber content has a slight impact on density change (the increase of about 1 g/mm3 per 10 per cent). Findings The use of polymers as a matrix allows to give composites features such as: lightness, corrosion resistance, damping ability, good electrical insulation and thermal and easy shaping. Polymers used as a matrix perform the following functions in composites: give the desired shape to the products, allow transferring loads to fibers, shape thermal, chemical and flammable properties of composites and increase the possibilities of making composites. Fiber-reinforced polymer composites are the effect of searching for new construction materials. Glass fibers show tensile strength, stiffness and brittleness, while the polymer matrix has viscoelastic properties. Glass fibers have a uniform shape and dimensions. Fiber-reinforced composites are therefore used to increase strength and stiffness of materials. Polymers have low tensile strength, exhibit high deformability. Polymers reinforced by glass fiber have a high modulus of elasticity and therefore provide better the mechanical properties of the material. Composites with glass fibers do not exhibit deformations in front of cracking. An increase in the content of glass fiber in composites increases the tensile strength of the material. Polymers reinforced by glass fiber are currently one of the most important construction materials and are widely used in the aerospace, automotive and electro-technical industries. Originality/value The paper presents the test results for polyethylene composites with 25 per cent and 50 per cent filler coming from recycled car carpets of various car makes. The tests included using differential scanning calorimetry, testing material hardness, material tensile strength and their dynamic mechanical properties.

Determination of compressive strength of 3D polymeric lattice structure as template in powder metallurgy

Powder metallurgy has been developed to fabricate metal foams from various materials including magnesium. One particular challenge on powder metallurgy is fabrication of highly-ordered and interconnected porous products. Pores interconnectivity is important in application of porous magnesium alloy for biodegradable orthopedic implants. Meanwhile, 3D polymeric printing technology offers capability to build precise and rapid lattice wireframe products in a simple and low-cost manner. Here, we design and validate the capability of 3D polymeric lattice as template in powder metallurgy for fabrication of magnesium-based biodegradable implants. Lattice structures were made of ABS, PLA, and PVA filaments. Lattice structures were cubical-shaped with uniform dimension and variations in pore size are included in the study. Both computational and experimental tests are performed to determine the compressive strength of the lattice structures. Uniaxial stress with uniform magnitude is applied to test the lattice structures. The resulting stress, strain, and deformation of the 3D polymeric lattice are observed. Variations in materials and pore size affect the stress, strain and deformation of the 3D polymeric lattice. Parameters can be further optimized to meet the requirement of the design and fabrication process in consideration of the tolerable stress, strain and deformation.
