Nano drops a million times smaller than a teardrop explodes 19th century theory

(University of Warwick) Droplets emanating from a molecular ‘nano-tap’ would behave very differently from those from a household tap 1 million times larger — researchers at the University of Warwick have found. This is potentially crucial step for a number of emerging nano technologies, e.g., manufacture of nano-sized drug particles, lab-on-chip devices for in situ diagnostics, and 3D printers capable of nanoscale resolution.

A new way to measure solar panel degradation

How does one inspect solar panels in real time, in a way that is both cost-effective and time-efficient? Researchers have now developed and improved statistical and machine learning-based alternatives to enable real-time inspection of solar panels. Their research found a new application for clustering-based computation, which uses past meteorological data to compute performance ratios and degradation rates.

MU scientists use smartphones to improve dismal rating of nation’s civil infrastructure

(University of Missouri-Columbia) In the United States, aging civil infrastructure systems are deteriorating on a massive scale. A recent report by the American Society of Civil Engineers gave these systems a D+ rating nationwide on an A-F scale. Now scientists at the University of Missouri have developed smartphone-based technologies that can monitor civil infrastructure systems such as crumbing roads and aging bridges, potentially saving millions of lives.

Engineers develop room temperature, two-dimensional platform for quantum technology

Researchers have now demonstrated a new hardware platform based on isolated electron spins in a two-dimensional material. The electrons are trapped by defects in sheets of hexagonal boron nitride, a one-atom-thick semiconductor material, and the researchers were able to optically detect the system’s quantum states.

New model predicts how ground shipping will affect future human health, environment

The trucks and trains that transport goods across the United States emit gases and particles that threaten human health and the environment. A new project developed a new model that predicts through 2050 the impact of different environmental policies on human mortality rates and short- and long-term climate change caused by particulate and greenhouse gas emissions.
