In the wine bottling process, thermoplastics are commonly used to manufacture crown of cork stoppers. The production agglomerated stoppers generates a type waste called powder (CoP) in large volumes with known properties but which still underutilized. At present, although there many agrocomposites available additives such as natural fibers or solid residues from agricultural products, no studies describing formation these petroleum-derived synthetic plastics combined dust reinforcement for...

Currently, Total Hip Replacement (THR) hip prosthetics are typically made from metallic materials using subtractive manufacturing, and they not personalized. These materials, with higher densities than trabecular bone, can cause microfractures due to fatigue cycles. This study aims demonstrate the feasibility of Polyetherimide (PEI) as a rigid thermoplastic in additive offering viable alternative for patient-specific prostheses humans or pets. The starting point was commercial prosthesis,...

One of the most efficient measures to prevent gamma radiation is shielding, which can take form protection barriers, storage containers, wall coating, bunkers, or many others aimed at minimizing exposure people radiation. The materials used this end have not changed much since invention X-rays, when with high attenuation capacity were employed, such as lead, tungsten, concrete. These are all high-density and, therefore, also very heavy, and some them expensive environmentally friendly, they...

Objectives To obtain 3D printed bone models with a haptic sensation similar to that of the real bone, which will help surgeon learn and improve based on practice.

The decision-making in the investment of a new line stoppers based on agglomerated cork requires knowledge composition and its contribution to performance. For this, it is necessary observe leading products market test series prototypes with different formulations. development manufacturing made by cork, such as bottle stoppers, benefits strongly from accurate chemical structural characterizations, correlated final material A wise starting point fulfill requirement consist comparing...

The consumption of plastic raw materials has been exponentially growing throughout the world in last decade and so has, same proportion, their associated waste. Recycling through mechanical treatment heavy fraction these plastics is most economic safest alternative to use this waste recirculate it for reuse within industry or other related industries located near place where generated. In paper, a study characterization post-processing recycled high density polyethylene received by hazardous...

The increase in the number of revision surgeries after a total knee replacement surgery reaches 19%. One reasons for majority revisions relates to debris ultra-high molecular weight polyethylene that serves facilitate sliding between femoral and tibial components. This paper addresses biomechanical properties ULTEMTM 1010 totally new design, based on one commercial models Stryker manufacturer. It is designed produced through additive manufacturing replaces component such way as reduce pieces...

Current commercial software tools implement turbulence models on computational fluid dynamics (CFD) techniques and combine them with fluid-structural interaction (FSI) techniques. There are currently a great variety of methods that worth investigating through comparative study in order to delineate their behavior scaffolds used tissue engineering bone regeneration. Additive manufacturing (AM) offers the opportunity obtain three-dimensional printed (3D scaffolds) designed respecting...

Abstract Traditionally, cork stoppers composed of a plastic crown and spike, usually agglomerated or technical, are used to seal the bottles. The use synthetic for caps derived from petroleum generates well-known environmental problems; therefore, it is great interest seek substitutes, deepen research, develop new products production methods focused on this powerful industry. This work aims alternatives currently available market, not only in terms design materials, but also by exploring...

Background: This study describes a novel biomaterial consisting of mixture biphasic bioceramic obtained from waste generated by the sugar industry (Carbocal) and medical-grade epoxy resin adhesive called LOCTITE® M31 CLTM. The objective was to demonstrate possibility coating non-bioactive non-biodegradable metallic surfaces on implantable elements. Methods: After preparation, applied hip prostheses composed two distinct materials: polyetherimide grade 5 titanium. In both cases, adhesion...

The leather industry is experiencing a significant rise in production, resulting an increase discarded materials–often classified as urban waste—that end up landfills or are incinerated. Given the geographical proximity of goods sector Ubrique to cork stopper manufacturing El Puerto de Santa María/Jerez and viticulture Jerez/Sanlúcar/Chiclana, it essential explore synergies that can address environmental challenges by contemplating circular economy approach. This study focuses on existing...

This study focuses on developing hydroxyapatite synthesized from a CaCO3-rich byproduct of sugar beet processing called Carbocal® using hydrothermal reactor. The purpose this biomaterial is to enhance the osteoinductivity implantable surfaces and serve as bone filler, providing sustainable economically more affordable alternative. research involved compositional analysis micro- macrostructural physicochemical characterization, complemented with bioactivity live/dead assays. biphasic nature...

This works describes the agents involved in supply chain of aeronautical sector. These are charge receiving and processing truthful information that is subject to a series risks. Within paradigm globalisation markets, aeronautics industries must face risks derived from decentralisation their value processes. Even though this mainly aimed at reducing costs, it also generates uncertainty due introduction suppliers developing markets. We propose methodology helps identify classify these allows...
