Abstract Silicon nanostructures are attracting growing attention due to their properties and promising application prospects in solar energy conversion and storage devices, thermoelectric devices, lithium-ion batteries, and biosensing technologies. The large-scale and low-cost preparation of silicon nanostructures is critical for silicon-based advanced functional devices commercialization. In this paper, the feasibility and mechanism of silicon nanostructure fabricated by non-metallic carbon catalytic etching, as well as the currently existing problems and future development trend are reviewed.

False Dichotomy

Don Ihde examines the “congenital dystopianism” shared by environmentalists, environmental philosophers, and philosophers of technology. Each group employs a “rhetoric of alarm” that connects the use of technologies with environmental degradations. Ihde calls attention to how excessive rhetorical strategies have locked us into a false dichotomy: either technological-environmental utopianism or dystopianism. The problem is that we have not yet fully diagnosed either what our technologies can or should do, or what the environmental crises actually are. So long as we continue to accept either utopian or dystopian forecasts we are unlikely to bring either technologies or ecosystems into appropriate focus. Techno-environmental problems are complex, ambiguous, and interwoven; they rarely lend themselves either to an easy techno-fix or simple solution. The hardest problem of them all is how to turn major actors in the economy green: large scale development projects and multinational corporations. The challenge for a proactive philosopher is to get on the ground floor of technological research and development in order to help figure out how to green the economy itself.

Beta Galactosidase

β-Galactosidase is an important industrial enzyme in the hydrolysis of milk and whey lactose. The enzymatic hydrolysis of lactose allows to avoid health and environmental problems posed by this disaccharide. In addition, this enzyme catalyses the formation of galacto-oligosaccharides, which are prebiotic additives for the so-called “healthy foods”. β-Galactosidase is one of the relatively few enzymes that have been used in large-scale processes in both free and immobilised forms. This article presents a review of recent trends in immobilisation of β-galactosidase and their application in food industry.

Unique Nature

Infectious disease research spans scales from the molecular to the global—from specific mechanisms of pathogen drug resistance, virulence, and replication to the movement of people, animals, and pathogens around the world. All of these research areas have been impacted by the recent growth of large-scale data sources and data analytics. Some of these advances rely on data or analytic methods that are common to most biomedical data science, while others leverage the unique nature of infectious disease, namely its communicability. This review outlines major research progress in the past few years and highlights some remaining opportunities, focusing on data or methodological approaches particular to infectious disease.

Irritable Bowel

Irritable bowel syndrome is a functional disorder characterized by abdominal pain or discomfort associated with altered bowel habits. Due to the uncertainty of the pathogenesis of IBS and the diversity of its clinical manifestations, IBS cannot be completely cured. Increasing evidence suggests the key role of altered intestinal microbiota in the pathogenesis of IBS. Therefore, attention is being shifted to adjusting the changes in intestinal microbiota to control IBS symptoms. Fecal microbiota transplantation (FMT), antibiotics, probiotics, and synbiotics are currently often employed as treatment for IBS. And FMT is the most significant therapeutic efficacy with the least number of side effects. FMT provides a creative way to restore the abnormal gut microbiome in patients with IBS. But although current clinical studies confirm the effectiveness of FMT in the treatment of IBS, they are short-term studies of small samples, and there is still a lack of large-scale long-term studies. In this paper, we review the intestinal microbiota changes of IBS, the common methods of treating IBS with intestinal microbes, and the research status of FMT for the treatment of IBS. Finally, we put forward some opinions on the future research direction of FMT treatment of IBS.

CO2Sequestration with Enhanced Gas Recovery (CSEGR) is one of the efficient and attractive scenarios to reduce CO2emission and accelerate gas field to produce more natural gas simultaneously. We review the correlational experiments, simulations and economic feasibility research about technical and economic problems of CSEGR. And the potential of natural gas increase production and CO2emission reduction in China by CSEGR is calculated. The pilot projects and simulation results show that CSEGR is technically feasible when suitable injection strategies and field management are implemented. However, economic feasibility is available only via policies of carbon credit, allowance and trade. Accurate experimental data would ensure the authenticity of key simulation parameters and reliability of simulations, but the existed experimental data is scarce. More experimental researches should be conducted to obtain a great quantity of accurate data which can make the simulation more close to the actual situation. Accordingly, the pilot projects and large-scale applications of CSEGR could be implemented successfully.

Reverse Osmosis (RO) is an effective method to get fresh water from seawater or brackish water. The uncontrolled discharge of RO concentrated brine can contaminate water aquifers and damage marine ecosystems. The techniques to treat or utilize the rejected brine are the research focus in recent years. This paper tried to give an overview of latest development in this filed in order to provide references for its actual application in large-scale engineering.

AbstractForecasting the solar energy production is a key issue in the large-scale integration of the photovoltaic plants into the existing electricity grid. This paper reports on the research progress in forecasting the solar energy production at the West University of Timisoara, Romania. Firstly, the experimental facilities commissioned on the Solar Platform for testing the forecasting models are briefly described. Secondly, a new tool for the online forecasting of the solar energy production is introduced. Preliminary tests show that the implemented procedure is a successful trade-off between simplicity and accuracy.
