“…91,92 However, it is quite difficult to separate condensate water from air in microgravity. 93 It is usually done by mechanical extrusion, suction pump, rotary gas-liquid separator or absorbent material. 94 Mechanical separation process consumes more energy, while absorbent material needs to be recycled once saturated, limiting dehumidification capacity.…”

Air dehumidification plays an important role in improving air quality and maintaining thermal comfort. Increasing attention is paid to the membrane-based technology, which is based on water vapour transmembrane transport driven by mass transfer potential, together with sensible heat transfer under temperature difference. Membrane-based air dehumidification has been applied in heating, ventilation and air conditioning, compressed air dehumidification and environmental control in space vehicle, and some other engineering fields. This paper summarizes recent research results in these fields, including fundamental principles, membrane materials, membrane module structures, operation conditions and theory models. In the end, two methods of membrane-based dehumidification performance evaluation are introduced from perspective of energy and exergy, respectively.

“…Among marine organisms, sea cucumbers are interesting feedstocks with pharmaceutical activities. With these characteristics, they could be used in foods as well as biomedicine industries [2]. Recently, many studies provide scientific evidences that sea cucumbers contain various biologically active compounds that provide health benefits, such as antioxidant, antibacterial, antifungal, antiviral, anti-inflammatory activities and neuroprotective activities [3].…”

Investigations of alternative resources for production of functional foods and ingredients containing valuable compounds with biological activities are getting more and more attention. Sea cucumbers are aquatic functional foods with various medical and pharmaceutical effects, such as antioxidant, antibacterial, antifungal, antiviral, anti-inflammatory and neuroprotective activities. This study aimed to conduct profiling analysis of fatty acids and collagens extracted from four different sea cucumbers harvested from Papua New Guinea by using Gas Chromatrography-Mass Spectrometry (GC-MS) and Fourier Transform Infrared Spectrometer (FT-IR). Three different extraction methods in combination with various solvents were used to find the best combination for extracting fatty acids. Enzymatic and chemical extraction methods were applied for collagen extraction. The highest fat recovery in this study was 85.32% of theoretical yield with high proportions of unsaturated fatty acids up to 74.54%, and enriched with omega-3 fatty acid. FT-IR chromatogram of sea cucumber protein extracts showed the characteristic of collagen enriched with glycine and proline. The nutritional analysis of sea cucumber extracts demonstrated the potential use as functional foods and ingredients with high benefits to human health.
