In a circular textile economy, there is a requirement to reduce the consumption of new materials and encourage ways to keep materials and apparel in use for longer while utilising waste as a raw material. Repair and reinforcement of materials are circular practices that have been applied to extend the life cycle of apparel. The digitalisation of re...

摘要 伤口代表对皮肤的威胁, 而皮肤是身体最重要的抵御感染的屏障, 抗生素耐药性的增加促使了新疗法的发展.RO-101®是一种抗菌凝胶, 可以将过氧化氢 (H 2 O 2 ) 这种反应性氧化物直接释放到创面.本研究利用电纺技术将RO-101 ® 纳入聚乙烯醇 (PVA) 亚微米纤维网中, 该网可以作为传递剂, 实现持续释放, 并提供对感染的屏障。核磁共振波谱法进一步确认了该凝胶与亚微米纤维的充分结合。此外, 扫描电子显微镜显示直径在200–500纳米范围内的光滑均布网格。经过24小时, PVA/RO-101电纺网生成的H 2 O 2 浓度超过1 mM/(mL g) (1 mM = 1 mmol/L), 并评估了灭菌对H 2 O 2 释放的影响.我们发现PVA/RO-101网格对革兰阳性葡萄球...

There is a growing need for sensing materials that can provide multiple sensing capabilities for wearable devices, implantable sensors, and diagnostics tools. As complex human physiology requires materials that can simultaneously detect and respond to slow and fast pressure fluctuations. Mimicking the slow adaptive (SA) and fast adaptive (FA) mecha...

Polyethylene terephthalate glycol (PETG) is a difficult-to-spin material, and no previous papers have reported the correct conditions to create PETG meshes. To address this issue, a preliminary study on the solubility and electrospinnability of PETG using a range of solvent system was conducted and a Teas graph was established to select the ideal s...

In 4D printing, complex active structures are produced and investigated using several materials. However, research on designing cross folding origami structures and their use for direct 3D printing with direct CAD design was not previously reported. This research focuses on designing cross folding origami structures using computational origami for...

The use of Electroactive polymers (EAPs) in biomedical applications is a very promising approach being investigated for applications such as body sensors and muscle like actuators. In this field, Poly (vinylidene fluoride) (PVDF) is a potentially relevant material due to its interesting ferroelectric, piezoelectric, and pyroelectric properties as w...

The production of scaffolds for bone tissue applications is requiring a combination of physical and biological properties, which are depending on the materials morphology and pro-cessing conditions during the production process. The aim of the paper is the investigation of rheological behaviour of polymer and composite blends regularly used for the...

This paper is investigating the use of composite armour reinforced by nanomaterials, for the protection of light armoured (LAV) and medium armoured military vehicles (MAV), and the interaction between the composite materials and high-performance ballistic projectiles. Four armour materials, consisted of front hybrid fibre reinforced polymer cover l...

This research investigates the accelerated hydrolytic degradation process of both anatomically designed bone scaffolds with a pore size gradient and a rectangular shape (biomimetically designed scaffolds or bone bricks). The effect of material composition is investigated considering poly-ε-caprolactone (PCL) as the main scaffold material, reinforce...

The yellow rust of wheat (caused by Puccinia striiformis f. sp. tritici) is a devastating fungal infection that is responsible for significant wheat yield losses. The main challenge with the detection of this disease is that it can only be visually detected on the leaf surface between 7 and 10 days after infection, and by this point, counter measur...

The use of biocompatible and biodegradable porous scaffolds produced via additive manufacturing is one of the most common approaches in tissue engineering. The geometric design of tissue engineering scaffolds (e.g., pore size, pore shape, and pore distribution) has a significant impact on their biological behavior. Fluid flow dynamics are important...

The use of external fixation devices is considered a valuable approach for the treatment of bone fractures, providing proper alignment to fractured fragments and maintaining fracture stability during the healing process. The need for external fixation devices has increased due to an aging population and increased trauma incidents. The design and fa...

Microcellular injection moulding (MuCell®) is a polymer processing technology that uses a supercritical fluid inert gas, CO2 or N2, to produce light-weight products. Due to environmental pressures and the requirement of light-weight parts with good mechanical properties, this technology recently gained significant attention. However, poor surface a...

The detection of glucose is crucial in the management of diabetes and other medical conditions but also crucial in a wide range of industries such as food and beverages. The development of glucose sensors in the past century has allowed diabetic patients to effectively manage their disease and has saved lives. First-generation glucose sensors have...

The search for materials with improved mechanical and biological properties is a major challenge in tissue engineering. This paper investigates, for the first time, the use of Polyethylene Terephthalate Glycol (PETG), a glycol-modified class of Polyethylene Terephthalate (PET), as a potential material for the fabrication of bone scaffolds. PETG sca...

Shape memory polymers represent a class of polymers that can recover its original shape under stimulus. This paper presents the preliminary results of a broader research programme that investigates the potential use of polyethylene terephthalate glycol (PETG), a glycol modified version of polyethylene terephthalate (PET), for the fabrication of sma...

Every year there are about 3500-5200 people suffering from upper limb amputations, most of which are wrist disarticulation and transcarpal. This paper investigates current upper limb prostheses and presents the disadvantages of current prostheses, including limited degrees of freedom (DOF), limited range of motion, weight, customizability, and appe...
