Despite significant advancements in bio-based natural-fiber-reinforced composites, the recyclability/reprocessing of thermoset composites remains a persistent challenge that needs to be addressed. In present study, an effort is made provide justification for assessment sandwich composite panels with ‘recyclate’ (i.e., recycled flax/bio-based epoxy composite) cores and (flax/bio-based epoxy) ski...

In this study, alternative core materials to commercial cork were searched for. Additionally, aging of new was studied. Bio-based in sandwich structures can be useful for sports equipment, transportation, and furniture with much less impact on the environment comparison their synthetic counterparts. paper, panels made fiber-reinforced polymer (FRP) skins various sustainable a thickness 6 mm The...

Pervaporation membrane technology plays an important role in production of renewable bio-fuels. To improve the separation performance of polymeric membranes, an effective approach is development of mixed-matrix membranes containing high-performing fillers such as metal-organic frameworks. Towards practical application, hollow fiber could be an ideal substrate for mixed-matrix composite membrane...

Arsenic (As(V)), a highly toxic metalloid, is known to contaminate wastewater and groundwater difficult degrade in nature. However, the development of efficient adsorbents, at low cost for use practical applications, remains challenging. Thus, investigate As(V) adsorption mechanism, novel porous α-Fe2O3/Fe3O4/C composite (PC-Fe/C-B) was prepared, using bamboo side shoots as bio-template, breakt...

The increasing demand for eco-friendly materials and technology has made the industry focus on bio-compatible composites. This researchers explore potential of eco-friendly, bio-degradable, inexpensive banana fibre automotive applications. work reports preparation testing natural hybrid composite fibres randomly oriented with without adding silica filler (5–15 wt.%) through a hand lay-up proces...

Humidity responsive materials are increasingly attracting significant interest for soft robotics and deployable structures. Their shape-changing behavior is based on differential hygroscopic characteristics of the single components their microscopic architecture. Although existing moisture-induced achieve morphing in various humidity conditions, practical operational environments involve presen...

Epoxy is the most prevalent thermosetting resin in field of polymer composite materials. There has been a growing interest development bio-based epoxy resins as sustainable alternative to conventional petrochemical resins. Advances this recent years have included use various renewable resources, such vegetable oils, lignin, and sugars, direct precursors produce In meantime, bio-oils produced vi...

Porous silicon (PS) substrates, with different pore sizes and morphology, have been used to crystallize hydroxyapatite (HA) nano-fibers by an easy and economical procedure using a co-precipitation method at room temperature. In situ formation of HA nanoparticles, within the meso- and macroporous silicon structure, resulted in the formation of nanometer-sized hydroxyapatite crystals on/within th...

In this paper the challenge of enhancing the gain and reducing the power requirement of amplifiers, preferably used in biomedical applications is addressed by demonstrating that composite cascode stages, operating in subthreshold/weak inversion regions provide a method of designing a ultra high gain (97dB) and low-power (21μW) op amp with 1.5V power supply. The op amp is designed without compen...
