Purpose This paper aims to target print functionally gradient materials (FGM) devices made of immiscible polymers in multi-material fused deposition modelling (FDM) systems. The design is intended improve adhesion dissimilar thermoplastics without the need for chemical compatibilization so that filaments from many different sources can be used effectively. Therefore, there a invent an alternative solution printing multiple FDM system with desired adhesion. Design/methodology/approach In this...
This study focused on developing pigmented linear low-density polyethylene (LLDPE) sheets while preserving their mechanical properties and infrared (IR) transparency. Six pigments-ZnO, ZnS, TiO2, FeO yellow, light brown, dark brown-were each mixed with (PE) wax in a 1:1 ratio blended LLDPE at concentrations of 1, 3, 5 wt%. Tensile strength tests showed minimal changes lower pigment concentrations, values near that pure (14 MPa), slight reductions IR transparency tests, conducted using both...
The sustainable growth of industries that consume a large amount fresh water relies on developing energy-efficient wastewater treatment processes. Nanofiltration (NF) has been widely considered for such purposes; however, the fabrication highly permeable NF membranes while maintaining high removal rate ions and organic matter remains big challenge. Here, we fabricated micropatterned thin-film composite (TFC) using two-step process. First, hydrogel-facilitated phase separation (HFPS) method...
Abstract In this work a novel method is presented to directly apply microscale patterns on the membrane surface using hydrogel facilitated phase separation (HFPS). The mold initiates spontaneously when it contacts polymer solution and guarantees that location of dense skin layer patterned side. fashion, active area larger than equivalent flat subsequently enhances water flux without changing chemistry. morphological properties HFPS membranes show similarity nonsolvent induced ones; however,...
This study investigates the application of co-polyamide (Co-PA) membranes in pressure-retarded osmosis (PRO) process, highlighting their enhanced performance and sustainability, as shown by life cycle assessment.
Fused granular fabrication (FGF) is a cost-effective and increasingly popular additive technology that enables the production of parts using wide range exotic materials are not typically available with material extrusion manufacturing. This paper presents novel needle valve approach for flow control in FGF system uses flexibly connected screw extruders. The addition to existing allows complex travel moves be performed without stringing, greatly increasing part complexity printer. actuated by...
In this study, we explore the innovative application of biological principles scattering foams and structural colouration white materials to manipulate transmission properties thermal infrared (IR) radiation, particularly within 8-14 μm wavelength range in polyolefin materials. Inspired by complex skin organisms such as chameleons, which can dynamically change colour through alterations, well more mundane technologies Buddha Boards magic water colouring books, are developing methods control...
Processing high-performance aluminum alloys, including 6xxx and 7xxx series, via laser additive manufacturing (AM) processes poses significant challenges, primarily due to the rapid cooling rates inherent in these processes, which often result solidification cracking metallurgical defects. This study aimed at producing dense, crack-free samples of Al6061 using powder bed fusion (L-PBF) process. Taguchi’s method design experiments was employed effects power, scanning speed, hatch spacing on...
Hydrogel-facilitated phase separation (HFPS) has recently been applied to make microstructured porous membranes by modified processes. In HFPS, a soft lithographically patterned hydrogel mold is used as water content source that initiates the process in membrane fabrication. However, after each casting, changes due diffusion of organic solvent into from original solution. The absorption limits continuous use repeated casts. this study, we investigated simple treatment for recovery,...
Abstract This work utilizes predictive modeling techniques to guide and inform metamaterial design for heat management solutions thermal radiation control. Specifically, micro‐ macro‐scale polyethylene‐based are proposed passive active camouflage. A micro‐scale post is highly‐tunable infrared emissivity based on varying unit cell geometrical configurations. Actively modulating these micro‐features through lateral straining of up 3% allows redshifting the spectrum by 0.5 µm. Macro‐scale...
This study demonstrates a multi‐spectrum camouflage control via microfluidic methods within thermally and visibly semi‐transparent polymer (polyethylene). Microfluidic devices have high potential for achieving multiband including both visible infrared (IR) spectrums because they can manipulate fluids that may be dyed, transparent, or opaque to different parts of the electromagnetic spectrum. However, most traditional polymers used microfluidics are not very transparent in thermal IR region...
We present in this work new methodologies to produce, refine, and interconnect room-temperature liquid-metal-core thermoplastic elastomer wires that have extreme extendibility (>500%), low production time cost at scale, may be integrated into commonly used electrical prototyping connectors like a Japan Solderless Terminal (JST) or Dupont connectors. Rather than focus on the development of specific device, aim is demonstrate strategies processes necessary achieve scalable liquid-metal-enabled...
Adab adalah merupakan bagian pendidikan yang sangat penting, berkaitan dengan aspek-aspek sikap dan nilai, baik individu ataupun berhubungan sosial masyarakat. akan memberikan pengaruh dalam kehidupan sehingga ada pepatah mengatakan “Al-Adabu Fauqal Ilmi” (adab itu lebih tinggi dari ilmu”. Oleh karena nilai terkandung agama perlu diketahui, dipahami, diyakini diamalkan oleh manusia agar dapat menjadi dasar kepribadian utuh. Mengingat begitu pentingnya adab sampai hal terkecil pun mempunyai...
