(Press-News.org) In United Nations Sustainable Development Goals, Number 6, addresses the need for access to clean water and sanitation for all. In the worldwide situation, one in three people do not have access to safe drinking water, and two out of five do not have basic hand-washing facilities with soap and water.
Water quality also address to elements dissolved. In the case of fluoride, controlled amount are recommended for protect tooth, e.g. included in toothpaste. Higher levels can cause fluorosis, interfere in tooth enamel formation, correct growth of the bones, and cause crippling deformities of the spine and joints. The incidence of higher concentrations of fluoride in water is higher in rural areas without access to an appropriate water network.
Fluoride in water sources has a geogenic origin instead of anthropogenic, the fluoride concentration in water is determined by geological formations in riverbeds. This, making the fluoride distribution inhomogeneous in the affected regions, finding water sources with safe and unsafe fluoride levels in a close distance. In this case, the fluoride problem could be solved by the local population provided with specific equipment to detect the levels of fluoride in the water and help them to consume safe water.
The equipment cost for fluoride detection is moderate to high, and requires training to be used effectively. This cost is not affordable for the populations in rural areas. For these reasons, the group led by Professor Mutsumi Kimura and Dr. Eugenio Otal from Shinshu University decided to develop an affordable portable equipment which can detect fluoride in a simple manner at low costs, which was recently published in END

Understanding itch: New insights at the intersection of the nervous system & immune system
2021-04-02
Eczema, or atopic dermatitis (AD), is sometimes called "the itch that rashes." Often, the itch begins before the rash appears, and, in many cases, the itchiness of the skin condition never really goes away. Approximately 9.6 million children and 16.5 million adults in the U.S. have AD, which can have a serious effect on quality of life for patients. Although much has been learned about the uncomfortable sensation that triggers the desire to scratch, many mysteries remain about chronic itch, making it a challenge to treat. A paper by authors from Brigham and Women's Hospital and Harvard Medical School published in The Proceedings ...
In-situ nanoscale insights into the evolution of solid electrolyte interphase shells
2021-04-02
The interfacial decomposition products forming the so-called solid-electrolyte interphase (SEI) during the first charging/discharging significantly determine the electrochemical performances of lithium (Li) batteries. To date, the dynamic evolutions, chemical compositions, stabilities and the influencing factors of the SEI films have been captured tremendous attentions.
It's noted that, in contrast to the SEI film formation at the surface of electrodes, a kind of SEI shells usually conformally forms at the outmost layer of the on-site deposited Li once the freshly deposited Li contacts with the electrolyte, which could directly influence Li nucleation, growth behaviors ...
Commercially available ultralong organic room-temperature phosphorescence
2021-04-02
Purely organic room-temperature phosphorescence (RTP) materials have been a hot research topic. Currently, the pure RTP materials have been realized by the introduction of heavy halogen atoms, carbonyls groups or some heteroatoms, hydrogen bonding, H-aggregation, strong intermolecular electronic coupling, molecular packing, host-guest interaction, etc. However, the complicated synthesis and high expenditure are still inevitable in these systems. In addition, their performances in air are not satisfactory and the introduction of halogen atoms is generally necessary. Therefore, a new facile and robust host-guest strategy utilizing only electron-rich materials is a promising alternative for constructing RTP systems.

Oxygen-promoted synthesis of armchair graphene nanoribbons on Cu(111)
2021-04-02
On-surface synthesis has received great attention as a method to create atomically-precise one-dimensional (1D) and two-dimensional (2D) polymers with intriguing properties. In particular, graphene nanoribbons (GNRs), a category of quasi-1D nanomaterials derived from graphene, have been widely studied due to their tunable electronic properties and potential applications in semiconductor devices, such as field-effect transistors and spintronics. A series of top-down approaches have been pursued to produce GNRs, but a lack of control over the ribbon width and edge structure has hindered their further development.
In 2010, Cai et al. firstly reported the fabrication of an atomically-precise armchair GNR (AGNR) on the Au(111) surface using a bottom-up ...
Depositing Fe species inside ZSM-5 to oxidize cyclohexane to cyclohexanone
2021-04-02
The directly catalytic oxidation of alkanes has high atomic economy and application value to form corresponding chemical organic products such as alcohols, aldehydes, ketones and carboxylic acid. It is challenging to achieve efficient and selective oxidation of alkane under mild conditions due to the inert C-H bonds of alkanes.
Many researchers have developed a series of supported iron based catalysts to simulate the alkane biological monooxygenase with iron center atoms. However, traditional methods, such as impregnation method, ion exchange method, etc., are ...
Scientists turn to deep learning to improve air quality forecasts
2021-04-02
Air pollution from the burning of fossil fuels impacts human health but predicting pollution levels at a given time and place remains challenging, according to a team of scientists who are turning to deep learning to improve air quality estimates. Results of the team's study could be helpful for modelers examining how economic factors like industrial productivity and health factors like hospitalizations change with pollution levels.
"Air quality is one of the major issues within an urban area that affects people's lives," said Manzhu Yu, assistant professor of geography at Penn State. "Yet existing observations are not adequate to provide comprehensive information that may help vulnerable populations ...
Kirigami-style fabrication may enable new 3D nanostructures
2021-04-02
A new technique that mimics the ancient Japanese art of kirigami may offer an easier way to fabricate complex 3D nanostructures for use in electronics, manufacturing and health care.
Kirigami enhances the Japanese artform of origami, which involves folding paper to create 3D structural designs, by strategically incorporating cuts to the paper prior to folding. The method enables artists to create sophisticated three-dimensional structures more easily.
"We used kirigami at the nanoscale to create complex 3D nanostructures," said Daniel Lopez, Penn State ...
Realtime imaging of female gamete formation in plants
2021-04-02
Scientists from Nagoya University, Yokohama City University and Chubu University have developed a system which enables the live imaging of the formation of the female gamete in plants.
In flowering plants, the sperm cell and egg cell meet and fertilization takes place in the flower. While sperm cells are made in the pollen, egg cells are made in the ovule, the structure that becomes the seed. However, as the ovule is buried deep within the pistil, it has thus far been impossible to observe the formation of the egg cell in living plants.
The team, led by Dr Daisuke Kurihara and Dr Tetsuya Higashiyama of Nagoya University Institute of Transformative Bio-Molecules (WPI-ITbM), Dr Daichi Susaki of Yokohama City University Kihara Institute for Biological Research ...
