TL;DR: In this article, a review of the available technologies for the synthesis of metal-organic frameworks (MOFs) and their applications in many prospective areas is provided. But, the authors do not provide a brief discussion about the applications of these materials.
141 citations
TL;DR: In this article, the average indoor concentrations of fine particles less than 2.5μm were collected from inside ten childcare centers, and from their adjacent outdoor environments in Seoul, Korea during the summer, autumn and winter seasons.
75 citations
TL;DR: Although emission concentrations of target compounds were in most cases below the permissible exposure limits (PEL), a proper regulation against the use of BBQ charcoal is needed to reduce potential health risks associated with its use.
67 citations
TL;DR: In this article, a survey at 26 ECCs in Korea between April 2013 and March 2014 was conducted to characterize the influence of seasonality on elderly care centers (ECCs) thermal environments; analyze elderly physical conditions; and assess indoor environments thermal parameters in Korean ECC.

TL;DR: Differences in RR values between the two bag types increased with storage time, such that RR of PEA bags were superior to those of PVF bags after three days, demonstrating that VOC in PEAbags were more stable than in PVFbags.

TL;DR: A review of natural fiber reinfocred composites focusing on natural fiber types and sources, processing methods, modification of fibers, matrices (petrochemical and renewable), and their mechanical performance is presented in this paper.
Abstract: This century has witnessed remarkable achievements in green technology in material science through the development of natural fiber reinforced composites. The development of high-performance engineering products made from natural resources is increasing worldwide day by day. There is increasing interest in materials demonstrating efficient use of renewable resources. Nowadays, more than ever, companies are faced with opportunities and choices in material innovations. Due to the challenges of petroleum-based products and the need to find renewable solutions, more and more companies are looking at natural fiber composite materials. The primary driving forces for new bio-composite materials are the cost of natural fibers (currently priced at one-third of the cost of glass fiber or less), weight reduction (these fibers are half the weight of glass fiber), recycling (natural fiber composites are easier to recycle) and the desire for green products. This Review provides an overview of natural fiber reinfocred composites focusing on natural fiber types and sources, processing methods, modification of fibers, matrices (petrochemical and renewable), and their mechanical performance. It also focuses on future research, recent developments and applications and concludes with key issues that need to be resolved. This article critically summarizes the essential findings of the mostly readily utilized reinforced natural fibers in polymeric composite materials and their performance from 2000 to 2013.

TL;DR: Application of breath biomarker measurement in a standardised manner will provide comparable results, thereby facilitating the potential use of these biomarkers in clinical practice, and highlighting future research priorities in the field.
Abstract: Breath tests cover the fraction of nitric oxide in expired gas (FENO), volatile organic compounds (VOCs), variables in exhaled breath condensate (EBC) and other measurements. For EBC and for FENO, official recommendations for standardised procedures are more than 10 years old and there is none for exhaled VOCs and particles. The aim of this document is to provide technical standards and recommendations for sample collection and analytic approaches and to highlight future research priorities in the field. For EBC and FENO, new developments and advances in technology have been evaluated in the current document. This report is not intended to provide clinical guidance on disease diagnosis and management. Clinicians and researchers with expertise in exhaled biomarkers were invited to participate. Published studies regarding methodology of breath tests were selected, discussed and evaluated in a consensus-based manner by the Task Force members. Recommendations for standardisation of sampling, analysing and reporting of data and suggestions for research to cover gaps in the evidence have been created and summarised. Application of breath biomarker measurement in a standardised manner will provide comparable results, thereby facilitating the potential use of these biomarkers in clinical practice.

TL;DR: It is hard to overstate the importance of oxygenated organic compounds in atmospheric chemistry, which play an active role in the sequence of chemical reactions responsible for tropospheric ozone formation in both polluted and remote environments.
Abstract: It is hard to overstate the importance of oxygenated organic
compounds in atmospheric chemistry. Oxygenated organic
compounds are emitted into the atmosphere from natural and
man-made sources, and they are formed in the atmosphere as
oxidation products of all hydrocarbons present in the
atmosphere. Oxygenated volatile organic compounds
(OVOCs) are generally more reactive than the alkanes from
which they are derived. OVOCs play an active role in the
sequence of chemical reactions responsible for tropospheric
ozone formation in both polluted and remote environments.
