Baltimore Charter on Sustainable Water Systems

Nelson V.I., Coalition for Alternative Wastewater Treatment, US

The Baltimore Charter on Sustainable Water Systems was drafted as a commitment to design new water systems that mimic and work with nature. These systems will both protect public health and safety and will restore [...]

Ultra Accelerated Quantum Chemical Molecular Dynamics Study on Mechanochemical Reaction of Micro-Bubble Induced by Shock Wave

Hatakeyama N., Nomura A., Sasaki Y., Chiba K., Hata H., Hatakeyama N., Okushi K., Suzuki A., Koyama M., Tsuboi H., Endou A., Takaba H., Kubo M., Del Carpio C.A., Kitada M., Kabashima H., Miyamoto A., Tohoku University, JP

Mechanochemical reactions and micro-bubble formation may take place in water under strong compression/rarefaction realized by shock waves e.g. generated in collapsing process of laser-induced bubbles. However, elementary processes of the micro-bubble have never been revealed [...]

Institutional Challenges and Opportunities: Decentralized and Integrated Water Resource Infrastructure

Nelson V.I., Coalition for Alternative Wastewater Treatment, US

The failure of mainstream water and wastewater utilities to adopt decentralized technologies can be attributed to institutional and market barriers. The framework of policies and markets need to be altered and expanded to include: integrated [...]

A Theoretical Study on Chemical Reaction of Water Molecules under Laser Irradiation: Ultra Accelerated Quantum Chemical Molecular Dynamics Approach

Endou A., Nomura A., Sasaki Y., Chiba K., Hata H., Hatakeyama N., Okushi K., Suzuki A., Koyama M., Tsuboi H., Hatakeyama N., Takaba H., Kubo M., Del Carpio C.A., Kitada M., Kabashima H., Miyamoto A., Tohoku University, JP

Recently, we succeeded in realizing ultra acceleration of our tight-binding quantum chemical molecular dynamics (TB-QCMD) simulator, New-Colors, which is more than 10,000,000 times faster the traditional first-principles molecular dynamics (FPMD) method. Our novel simulator enables [...]

Role of Nano-chirality and broken symmetry in hostile organism penetration of host cell DNA

Vezzoli G.C., Institute for the Basic Sciences, US

We show that broken symmetry, at the nano level, of biomolecules is key to phage invasion of a host cell, and take-over of the cell’s RNA-DNA replication processes. We determined that perturbation of cellular water [...]

Dynamics of Water in Nafion Fuel Cell Membranes: the Effects of

Moilanen D.E., Piletic I.R., Fayer M.D., Stanford University, US

The complex environment experienced by water molecules in the hydrophilic channels of Nafion membranes is studied by ultrafast infrared pump-probe spectroscopy. A wavelength dependent study of the vibrational lifetime of the O-D stretch of dilute [...]
