New algorithm predicts optimal materials among all possible compounds
Skoltech researchers have offered a solution to the problem of searching for materials with required properties among all possible combinations of chemical elements. These combinations are virtually endless, and each...
Watch: Chris Evans, Scott Evans take Bro Couples Challenge on 'Tonight Show'
Chris Evans took the Bro Couples Challenge with this brother, Scott Evans, on "The Tonight Show."
Elle Fanning, Nicholas Hoult find comedy in Cathering 'The Great'
Elle Fanning plays Catherine and Nicholas Hoult plays Peter III in a comedic take on history. "The Great" premieres Friday on Hulu.
There's a lot of buzz about 'green' hydrogen, but actual projects are slow in coming
In this week's issue of our environment newsletter, we look at the promise of 'green' hydrogen, Elon Musk's attitude to the COVID-19 lockdowns and what the federal government is doing...
Netflix picks up Dwayne Johnson-Emily Blunt film 'Ball and Chain'
Netflix announced Thursday it will release "Ball and Chain," a film based on Scott Lobdell's 1990s comic book of the same name.
Speeding up long-range coherent LiDAR
LiDAR is a technique used for measuring distances with laser light. Researchers now show a new way to speed up a type of LiDAR engine by using photonic circuits.
Boeing nabs $3.1B in cruise missile deals for Saudi Arabia, other partners
The Navy awarded Boeing with a combined $3.1 billion in contracts this week for cruise missile weapon systems for foreign partners, including Saudi Arabia.
2-D sandwich sees molecules with clarity
A sandwich of molybdenum, sulfur and selenium turns out to be deliciously useful for detecting biomolecules.
Making Quantum ‘Waves’ in Ultrathin Materials
Wavelike, collective oscillations of electrons known as “plasmons” are very important for determining the optical and electronic properties of metals. In atomically thin 2D materials, plasmons have an energy that...
Topological waves may help in understanding plasma systems
Nearly 50 years ago, Brown University physicist Michael Kosterlitz and his colleagues used the mathematics of topology—the study of how objects can be deformed by stretching or twisting but not...
Making quantum 'waves' in ultrathin materials
A team of researchers has observed unusually long-lived wavelike electrons called 'plasmons' in a new class of electronically conducting material. Plasmons are very important for determining the optical and electronic...

Understanding how urban smog particles grow quickly
Lab study points to ammonium nitrate formation as the culprit behind the mystery of air pollution in megacities
Response to Comment on "Dry reforming of methane by stable Ni-Mo nanocatalysts on single-crystalline MgO"
Hu and Ruckenstein state that our findings were overclaimed and not new, despite our presentation of evidence for the Nanocatalysts on Single Crystal Edges (NOSCE) mechanism. Their arguments do not...
Comment on "Dry reforming of methane by stable Ni-Mo nanocatalysts on single-crystalline MgO"
Song et al. (Reports, 14 February 2020, p. 777) ignore the reported efficient Ni/MgO solid-solution catalysts and overstate the novelty and importance of the Mo-doped Ni/MgO catalysts for the dry...
Quantum interference in H + HD -> H2 + D between direct abstraction and roaming insertion pathways
Understanding quantum interferences is essential to the study of chemical reaction dynamics. Here, we provide an interesting case of quantum interference between two topologically distinct pathways in the H + HD -> H2...
Photocurrent detection of the orbital angular momentum of light
Applications that use the orbital angular momentum (OAM) of light show promise for increasing the bandwidth of optical communication networks. However, direct photocurrent detection of different OAM modes has not...
Tunable topological charge vortex microlaser
The orbital angular momentum (OAM) intrinsically carried by vortex light beams holds a promise for multidimensional high-capacity data multiplexing, meeting the ever-increasing demands for information. Development of a dynamically tunable...
Diverse functionalization of strong alkyl C-H bonds by undirected borylation
The selective functionalization of strong, typically inert carbon-hydrogen (C–H) bonds in organic molecules is changing synthetic chemistry. However, the undirected functionalization of primary C–H bonds without competing functionalization of secondary...
Unlocking the gate to the millisecond CT
Many will undergo a CT scan at some point in their lifetime—being slid in and out of a tunnel as a large machine rotates around. X-ray computed tomography, better known...
General descriptor sparks advancements in dye chemistry
There is an ongoing demand in biological research to accelerate the development of fluorescent probes based on the photo-induced electron transfer (PET) mechanism. By modulating PET formations, these probes significantly...
A greener path toward vanillin from paper pulp
A new electrocatalytic process makes vanilla's main flavor compound from Kraft lignin
As Las Vegas starts to reopen, bet on lower room rates and smaller crowds
Some Las Vegas resort hotels hope to open for Memorial Day. Social distancing means smaller crowds, but rooms will be less expensive for now.
A new type of chemical bond: The charge-shift bond
John Morrison Galbraith is an associate professor of chemistry at Marist College who studies chemical bonding, which is the process that holds atoms together to make molecules.
Scientists Solve Mystery of Spontaneous Smog Formation
One of the peculiarities of air pollution in the world’s urban areas is that it is not always predictable. It is not uncommon for a major city, such as Beijing,...
Organic spacers improve LED performance
Light-emitting diodes (LEDs) release energy in the form of light when electrons and "holes" (electron vacancies) recombine in response to an applied voltage. Over the past few years, scientists have...
Graphene: Making a wonder material more wonderful
Graphene is a form of the chemical element carbon. Well-known forms of carbon include the world's hardest material, diamond, and the soft black material known as the "lead" in a...
