Waste cold recovery using thermoelectric power generator

Waste cold recovery using thermoelectric power generator

Recovery of wasted cold energy by TEG The worldwide energy crisis has made people realize the importance of the waste energy recovery, and waste heat recovery has become a popular topic of discussion. However, waste cold is also common. For instance, liquefied gas storage is necessary for hospitals, the natural gas industry, the semiconductor industry, etc. In cryogenic engineering, liquid nitrogen is widely employed in the food, biotechnology, electronics and semiconductor manufacturing, and...

Which nature is legitimate?

Which nature is legitimate?

Riverfront redevelopment and urban agricultureWith the popularization of environmentalism, a resurgence of urban agriculture has been observed in Taiwan in recent years. NGOs, communities and even the government advocate for community gardens, home gardening, farmers’ markets, local food movements and shrinking the food footprint. The legitimacy of urban agriculture has thus been elevated and even gained the endorsement of official policy.Moreover, Taipei’s riverfront area, which was...

Probing the photovoltaic properties of silver-doped Cu(In, Ga)Se2 films by a nonvacuum solution process

Probing the photovoltaic properties of silver-doped Cu(In, Ga)Se2 films by a nonvacuum solution process

The ever-increasing demand for energy resources and sustainable development has promoted the growth of thin-film photovoltaic technology. Cu(In, Ga)Se2 (CIGS) solar cells have come to the forefront and are extensively considered a promising type of thin-film solar cell owing to their increased efficiency and potential for application in building-integrated photovoltaic systems. A schematic diagram of a CIGS solar cell is shown in Figure 1.Figure 1. Schematic diagram of a CIGS solar cell.It is we...

Different classes of statins have varying effects on reducing sepsis mortality

Different classes of statins have varying effects on reducing sepsis mortality

Sepsis, a pathogen-induced systemic inflammation that leads to organ dysfunction, remains a major public health problem. Each year, an estimated 20 to 30 million patients develop sepsis, and the annual incidence is still increasing in many countries. However, anti-infective therapy may not be sufficient for all sepsis patients and could give rise to antibiotic-resistant bacteria. Thus, strategies that can resolve inflammation or reverse immune paralysis associated with sepsis are intensively stu...

A genome-wide methylation study of coronary artery ectasia

A genome-wide methylation study of coronary artery ectasia

Approximately 38 million people die from noncommunicable diseases (NCDs) globally per year (Global status report on noncommunicable diseases 2014: Attaining the nine global noncommunicable diseases targets; a shared responsibility, 2014), and the most important contributing factor to these deaths is cardiovascular disease. Cardiovascular diseases have become the top 3 causes of death not only in Taiwan but also worldwide ("World Health Organization website [http://www.who.int/mediacentre/factshe...

Parental habits of betel quids chewing are dose-dependently associated with a risk of metabolic syndrome in offspring

Parental habits of betel quids chewing are dose-dependently associated with a risk of metabolic syndrome in offspring

Betel chewing, a socially important custom, is an addictive habit recognized as causing oropharyngeal and other cancers. Chewers of the chopped nuts of the Areca catechu palm, wrapped in piper betel vine leaves or flowers [‘betel-quids’], take the habit with them across the globe and currently number ~700 million [10% of the world population]. Addictive arecal alkaloids form carcinogenic nitroso-compounds during digestion, and many nitroso-compounds induce type 2 diabetes [T2DM] at l...

Pre-market trading and IPO prices

Pre-market trading and IPO prices

Underpricing is a known issue associated with initial public offerings (IPOs) throughout the world. This phenomenon has been observed in Taiwan. Traditionally, information asymmetry is used to explain the existence of tremendous IPO-related underpricing. Taiwan has a well-organized pre-IPO market. Trading information in a pre-IPO market can ameliorate the information asymmetry problem. However, underpricing levels remain high even if there is trading on a pre-IPO market. Information asymmetry th...

Ten years of collaboration with the University of Illinois Urbana-Champaign

Ten years of collaboration with the University of Illinois Urbana-Champaign

The “Built Environment and Health” session of the collaboration between the University of Illinois at Urbana-Champaign (UIUC) and National Taiwan University (NTU) represents a cooperative project between Professor William C. Sullivan from the Sustainability & Human Health Lab and Professor Chun-Yen Chang from the Healthy Landscape and Healthy People Lab, who have been cooperating closely for the past 10 years. The team has primarily focused on “landscape and human health...

Coral record of an anthropogenic N perturbation in the remote open ocean

Coral record of an anthropogenic N perturbation in the remote open ocean

Like all organisms, marine phytoplankton require nitrogen to live and grow. Although the majority of the air we breathe is N2, the nitrogen in the atmosphere is not available for use by most phytoplankton; certain bacteria and cyanobacteria that are capable of breaking the strong N–N triple bond represent exceptions. Before organisms can use nitrogen, N2 gas must first be converted to a more chemically available form, such as ammonium, nitrate, or organic nitrogen. The inert nature of N2 m...

Glucose-sensitive self-healing hydrogel as sacrificial material for fabricating vascularized constructs

Glucose-sensitive self-healing hydrogel as sacrificial material for fabricating vascularized constructs

A major challenge in tissue engineering is the lack of proper vascularization. Because host-capillary invasion upon the implantation of man-made tissues requires several weeks to achieve complete vascularization, insufficient nutrient and oxygen supply may lead to cell death in the core of the implant, causing problems in tissue integration. Therefore, building a vascular network within a tissue construct is a very important issue (Figure 1). Although various approaches have been used to build v...
