We present a sustainable, inherently safe battery chemistry that is based on widely available and cheap materials, that is, iron and manganese hosted in alginate bio-material known from the food and medical industry. The resulting battery can be recycled to allow circularity. The electrodes were synthesised by the alginate caging the multi...

Trials of surface modifications using low pressure chemical vapor deposition (LPCVD) has successfully decreased the high temperature needed for the fabrication of SiC membrane from 2000°C to below 900 °C. With this great success on the reduction of the energy con-sumption, however, further studies on the chemical stability and the fouling...

Water scarcity and uneven distribution of water resources pose a significant challenge globally. Searching for alternative water resources could alleviate this issue. Municipal sewage reclamation with ceramic NF membrane has gained momentum nowadays. However, the inevitable fouling, especially organic fouling during membrane filtration, is the...

A reasonable recovery of excess sludge may shift the waste into wealth. Recently an increasing attention has been paid to the recycling of extracellular biopolymers from conventional and advanced biological wastewater treatment systems such as flocculent activated sludge (AS), bacterial aerobic granular sludge (AGS), and algal-bacterial AGS...

Alginate like extracellular polymers (ALE) recovered from excess sludge have been evaluated as an eco-friendly, cost effective and sustainable alternative to highly valued materials. However, the ALE extraction from flocculent sludge ranges normally from 90 to 190 mg/g VSS, which is only equivalent to the lowest edge of the ALE production...

Alginate like extracellular polymers (ALE) recovered from flocculent sludge has been identified as a kind of highly valuable biomaterials. However, the extraction protocols limit the production of biopolymers as ALE extracted from flocculent sludge is at a lower level, around 90–190 mg/g VSS. Under this circumstance, the eco-friendly and...

Transition metals supported on carbons play an important role in catalysis and energy storage. By pyrolysis of metal alginate, highly active catalysts for the Fischer-Tropsch synthesis (FTS) can be produced. However, the evolution of the carbon (alginate) and transition metal (Fe<sup>3+</sup>) during pyrolysis remains largely unknown and was...

Colloidal fouling has attracted increasing interest in the membrane field. Oil and water (O/W) emulsion droplet and Extracellular polymeric substance (EPS) are significant colloids in produced water and surface water, respectively. Oily wastewater is produced in many industrial processes such as oil and gas extraction processes, and can take a...

This paper explores the potential use of conductive alginate capsules encapsulating a bitumen rejuvenator as a new extrinsic self-healing asphalt method. The capsules combine two existing self-healing asphalt technologies: (1) rejuvenator encapsulation and (2) induction heating to create a self-healing system that will provide rapid and...

Self-healing asphalt, which is designed to achieve autonomic damage repair in asphalt pavement, offers a great life-extension prospect and therefore not only reduces pavement maintenance costs but also saves energy and reduces CO<sub>2</sub> emissions. The combined asphalt self-healing system, incorporating both encapsulated rejuvenator and...

Autonomous healing by the microbially induced calcite precipitation (MICP) mechanism has garnered significant interest in the sustainable approach to concrete repair and maintenance. Previous research works have reported that Bacillus pasteurii and Bacillus sphaericus are the most commonly used in concrete associated with bacteria. However,...

Rejuvenator encapsulation technique showed great potential for extrinsic asphalt pavement damage healing. Once the capsules are embedded within asphalt pavement, the healing is activated on-demand via progressing microcrack. When the microcrack encounters the capsule, the fracture energy at the tip opens the capsule and releases the...

Porous asphalt, due to its advantages of noise reduction and water drainage, is widely used in the surface layer of the highway in the Netherlands. However, the porous structure makes it prone to ravelling, therefore more frequent maintenance and reconstruction than other asphalt mixtures The porous asphalt service life can be extended with self...

Previous research proved the potential of using mussel shell waste as additive manufacturing (AM) material. In this thesis, mussel shell powder was combined with sodium alginate, since it allows reversible cross-linking. Due to reversible cross-linking, this water-soluble and recyclable material can temporarily be made water-resistant, so it can...

Salts of trivalent cerium (Ce(III)) are known to successfully hinder localised corrosion phenomena typical of aerospace aluminium alloys by forming a thin passivation layer on top of the corrosion-active intermetallic phases. This is generally observed to happen when the alloy is under immersion conditions in a solution containing Ce3+ ions....

This paper presents a unique self-healing system for asphalt pavement which employs compartmented calcium-alginate fibres encapsulating an asphalt binder healing agent (rejuvenator). This system presents a novel method of incorporating rejuvenators into asphalt pavement mixtures. The compartmented fibres are used to distribute the rejuvenator...

Advancements in energy storage technologies need to keep pace with the accelerating transition to renewable energy sources. Li metal anodes and high voltage cathode materials are widely considered to be the path into next generation Li-ion batteries, while the scare amounts of lithium in the earth's crust has prompted research into other battery...

Improving the healing capacity of asphalt is proving to be an effective method to prolong the service life of an asphalt pavement. The calcium alginate capsules encapsulating rejuvenator have been developed and proved to provide successful localized crack healing in asphalt mastic. However, it is not known whether this self-healing asphalt...

It has been demonstrated that calcium alginate capsules can be used as an asphalt healing system by pre-placing rejuvenator (healing agent) into the asphalt mix and releasing the rejuvenator on demand (upon cracking). This healing mechanism relies on the properties of capsules which are determined by the capsule preparation process. In this...

We report visible light-driven, asymmetric hydrogenation of C=C bonds using an ene-reductase from Thermus scotoductus SA-01 (TsOYE) and a light-harvesting dye (rose bengal, RB) co-immobilized in an alginate hydrogel. Highly efficient encapsulation of RB in alginate hydrogel was achieved using the intrinsic affinity between TsOYE and RB,...
