Born to Modulate: Researchers Reveal Origins of Climate-Controlling Particles
Aerosol particles imbue climate models with uncertainty. New work by PNNL researchers reveals where in the world and under what conditions new particles are born.
Shrivastava Gives Keynote at Atmospheric Optics Meeting
Shrivastava invited to present a keynote talk on secondary organic aerosols at Air & Waste Management Association conference.
Wildfires Trigger Violent Storms with Large Hail and Lightning
Research reveals how heat and aerosols from wildfires initiate and invigorate severe storms.
More Urbanization Could Mean More Rain for Cities
A new study shows that urban heat island effects and increased urban aerosols can spur intense rainfall.
Sulfur Dioxide Emission Height Reveals Uncertainty in Radiative Forcing Across Earth System Models
The Emissions Model Intercomparison Project examined how selected emissions-related properties affected results in 11 global chemistry and Earth-system models.
Emulating Interactions Between Atmospheric Particles and Light with Machine Learning
Randomly constructed neural networks can learn how to represent light interacting with atmospheric aerosols accurately at a low computational cost and improve climate modeling capabilities.
SYSTEM AND METHOD OF PRECONCENTRATING ANALYTES IN A MICROFLUIDIC DEVICE
Electrokinetic injection is used almost exclusively for microchip electrophoresis. We describe a new approach, based on pneumatic valving, that overcomes the limitations of electrokinetic injection. A detailed description is in the attached file.
Spatial Heterogeneity of Clouds Impacts Rain Initiation in Global Models
The rate of conversion of cloud droplets to precipitation, known as the autoconversion rate, remains a major source of uncertainty in characterizing aerosol’s cloud lifetime effects and precipitation in global and regional models.
Signal Transmitter and Methods for Transmitting Signals from Animals
Injectable transmitters are provided that can include a body with the body housing a power source and an oscillator, the injectable transmitter also including an antenna extending from the body, the body and antenna being of sufficient size to be injected through a 9 gauge needle. Radio frequency transmitters are provided that can include a body extending from a nose to a tail with the body housing a power source and RF signal generator components. The power source of the transmitter can define at least a portion of the nose of the body. The transmitters can have an antenna extending from the tail. Methods for attaching a radio frequency (RF) transmitter to an animal are provided. The methods can include providing an RF transmitter and providing an injection device having a needle of gauge of 9 or smaller; providing the RF transmitter into the injection device; and providing the RF transmitter through the 9 gauge or smaller needle and into the animal.
