    Abstract Duckweed, a floating macrophyte, has attracted interest in various fields such as animal feedstocks and bioenergy productions. Its enriched nutritional content and rapid growth rate make it particularly promising. However, common laboratory cultures of duckweed often experience fronds layering, diminishing the efficiency of sunlight capturing due to limited surface area on conventional cultivation platforms. In this work, we aimed to address the issue of fronds layering by introducing a novel cultivation platform - a superhydrophobic coated acrylic sheet. The sheet was prepared by spray-coating a suspension of beeswax and ethanol, and its effectiveness was evaluated by comparing the growth performance of giant duckweed, Spirodela polyrhiza, on this platform with that on a modified version. The superhydrophobic coated acrylic sheet (SHPA) and its variant with a metal mesh added (SHPAM) were employed as growing platforms, with a glass jar serving as the control. The plantlets were grown for 7 days with similar growth conditions under low light stress (25 μmol/m

    Abstract We report a case of an osteoid osteoma at the scapular glenoid that was treated with cryoablation. The patient presented with shoulder pain with subsequent CT and MRI imaging findings suspicious for an osteoid osteoma. The patient complained of persistent pain despite medical treatment and was referred to interventional radiology for consideration of ablation. CT-guided biopsy confirmed the diagnosis of osteoid osteoma and the patient underwent cryoablation of the lesion in the same session. The patient reported a substantial relief in her pain at a follow-up 4 weeks after the procedure. MRI performed 8 weeks after the procedure also confirmed radiographic remission of the lesion.

    Abstract Membrane distillation (MD) has lower operating temperature and potential to recycle waste heat for desalination which catches much attention of the researchers in the recent years. However, the biofouling is still a challenging hurdle to be overcome for such applications. The microbial growth rate, secretion and biofilm formation are sensitive to heat. Membrane distillation is a thermally driven separation, so the increase of temperature in the seawater feed could influence the extent of biofouling on the unit parts. In this review, we present the effect of temperature on algal growth, the range of temperature the microbes, marine algae and planktons able to survive and the changes to those planktons once exceed the critical temperature. Thermal effect on the biofilm, its composition and properties are discussed as well, with association of the biofilm secreting microbes, but the study related to membrane distillation unit seems to be lacking and MD biofouling factors are not fully understood. Characterization of the algae, biofilm and EPS that govern biofouling are discussed. This information not only will help in designing future studies to fill up the knowledge gaps in biofouling of membrane distillation, but also to some extent, assist in pointing out possible fouling factors and predicting the degree of biofouling in the membrane distillation unit.

    Abstract One of the challenges of integrating phytoremediation into a waste treatment system is the sensitivity of plant species to fluctuations in environmental conditions and the difficulty in estimating subsequent changes to their rates of uptake. In this study, we examine a method using the exponential decay equation to approximate the median uptake rate (MUR) of nutrients for three aquatic macrophyte species,

    Abstract Biofilm secreted by microalgae are extracellular polymeric substances (EPSs) composed mainly of polysaccharides, proteins, nucleic acids and lipids. These EPSs immobilize the cells and stabilize biofilm, mediating adhesion towards solid surfaces. The EPSs valorization through industrial exploitations and scientific works is becoming more popular, but the bottleneck of such studies is the lack of consensus among researchers on the selection of detection techniques to be used, especially for novice researchers. It is a daunting task for any inexperienced researcher when they fail to identify the right tools needed for microalgal biofilm studies. In this review, a well-refined analysis protocol about microalgal biofilm and EPSs were prepared including its extraction and characterization. Pros and cons of various detection techniques were addressed and cutting-edge methods to study biofilm EPSs were highlighted. Future perspectives were also presented at the end of this review to bridge research gaps in studying biofilm adhesion via EPSs production. Ultimately, this review aims to assist novice researchers in making the right choices in their research studies on microalgal biofilms in accordance to the available technologies and needs.
