Abstract Direct Energy Deposition (DED) 3D printing has gained significant importance in various industries due to its ability fabricate complex and functional parts with reduced material waste, repair existing components. Titanium alloys, known for their exceptional mechanical properties biocompatibility, are widely used DED applications, where they offer benefits such as lightweight design possibilities high strength-to-weight ratio. However, given the cost of titanium certain applications...
The utilization of pore forming agents (PFAs) in digital light processing (DLP) 3D printing to manufacture porous ceramics through their thermal decomposition has received a great deal attention. Nevertheless, even though the inner PFA microstructure green body is an essential precondition for tailoring properties ceramics, approaches established date have only focused on post-processing. To address this gap, present study demonstrates novel DLP approach elucidate how PFAs are formed bodies...
The low mechanical properties and printing speed of fused filament fabrication (FFF) have remained important barriers to their widespread adoption in the industry. This study focused on proposal a layer stacking scheme that increases reduces time through continuously varied Infill Pattern (ConVIP). ConVIP method showed 15.2% 40% ultimate tensile strength, elongation at break, compared conventional infill pattern within polylactic acid (PLA) filament. In addition, had been increased by 29.37%...
The influence of σphase on mechanical properties in type ER309L stainless steel has been investigated by small punch test. SA508 cl.3 reactor pressure vessel plates were overlay-cladded with the welding consumable different heat input rates. microstructure clad was composed fcc γ-austenite, a few percent bcc δ-ferrite and bct σ-phase. Area fraction σ-phase ranging approximately 2–8% depending condition. Ductile to brittle transition behavior observed clad, it strongly affected amount When...
Label-free optical biosensors have received tremendous attention in point-of-care testing, especially the emerging pandemic, COVID-19, since they advance toward early-detection, rapid, real-time, ease-of-use, and low-cost paradigms. Protein biomarkers testings require less sample modification process compared to nucleic-acid biomarkers'. However, challenges always are detecting low-concentration for early-stage diagnosis. Here we present a Rotationally Focused Flow (RFF) method enhance...
The extensive use of electronic and electrical equipment ever-increasing rate renewal inevitably generate numerous e-waste plastics which need to be disposed properly, eliminating the brominated flame retardants (BFRs) present in them can significantly alleviate their environmental impact. In study, TBBPA-bis-(2,3-dibromo-2-methylpropyl ether) (TBBPA-DBMP), a novel tetrabromobisphenol A-derived BFR, was removed using an extraction process assisted by ultrasonic alcohol extractants. Response...
In this study, we introduce a design for near-eye, wearable display (HMD: head mounted display) that can automatically control the user's interpupillary distance (IPD). addition, demonstrate test-bed module AR based on proposed design. Both adjustment accuracy and viewing effect through matching between user’s eyes are evaluated by experience in actual wearing of module. We left right eye pupils be measured adjusted using set IR camera sensors micro-actuator proposed. A half-mirror unit to...
Carbon nanotubes (CNTs) have been often implemented as an additive in photopolymer resins for photo-reactive manufacturing processes such vat photopolymerization (VP) 3D printing to endow various functionalities and improve properties of components. However, CNTs are known their effective UV absorption strong agglomeration tendency, which reduce the 3D-printability resin composites. Moreover, since varying dispersion qualities concentrations significantly influence curing depth photo-curing...
If the future driving condition such as road information and traffic can be predicted, use of electrical power source will controlled appropriately in order to improve fuel economy Hybrid vehicle. In this paper algorithm for prediction model rule-based controller HEV are developed verified through simulation test. With from 3D navigation, types (uphill, flat or downhill) (congestion free driving) predicted by Driving Condition Prediction System (DCPS). The determine control strategy...
Abstract A non-instrumented, single-use, affordable, and fully- yet safely-disposable DNA analysis system for Point Of Care (POC) diagnostic process has been proposed by integrating (1) a hydration-reactive mixture portable heating element as powerless actuator, (2) commercially available optical adhesive films valves, (3) an exothermic reaction-based recombinant polymerase amplification (RPA) non-instrumented amplification. The operational error tolerance of the valves was evaluated gas...
Abstract Despite the increasing demand for nanoscale biomolecule analysis point-of-care (POC) application, nanoparticle separation remains a challenge in many applications due to huge sample loss during separation, low throughput, large scale input materials requirement, and sophisticated technologies. As efficiency may affect subsequent processing analysis, robust reliable size-based technique is necessary. This study presents lab on chip system enhance performance by using rapid...
