Two-dimensional (2D) semiconducting materials have shown great potential in the development of electronic devices, such as wearables and smaller electronics. These materials offer advantages over bulkier counterparts due to their ability to retain carrier mobility even at reduced thickness. However, the use of 2D semiconductors in creating monolayer transistors, which are thinner versions of crucial

Constellations have always captured our imagination, sometimes requiring a healthy dose of creativity to see the hidden shapes and figures. Nonetheless, the recent discovery of two stone disks at the entrance of an ancient fort in Italy challenges our perception of these ethereal formations. These stones, adorned with subtle markings, have puzzled experts who believe
Many individuals who are trying to kick-start their weight loss or shed a few pounds before a special occasion often consider trying a crash diet. These diets, characterized by drastically reducing calorie intake to 800-1,200 calories per day for a few weeks at a time, have gained popularity due to influencers and social media. Proponents
Google has recently implemented measures to restrict third-party cookies for some users of its popular web browser, Chrome. This move marks a significant step towards the eventual elimination of these files, which have long been a source of concern for privacy advocates. However, Google emphasizes that the complete removal of third-party cookies will require approval
A recent study conducted by a team of engineers and atmospheric scientists at Harvard University, together with a colleague from the California Institute of Technology’s Jet Propulsion Laboratory, has shed light on the alarming increase in methane emissions resulting from the expansion of rice farming in parts of Africa. The researchers recalculated methane emissions due
For decades, the chemical industry has been plagued by its association with pollution and environmental harm. The image of billowing smokestacks and toxic waste discharges has overshadowed the crucial role that chemicals play in our everyday lives. However, there is hope for a more sustainable future. Caltech’s Karthish Manthiram, a respected professor of chemical engineering
The nature of dark matter, that enigmatic substance that makes up a significant portion of the universe, seems to have become even more perplexing. Recent observations of the more recent universe suggest that the distribution of dark matter has changed compared to its early spread after the Big Bang. It appears to be less clumpy
Spintronic devices have revolutionized the field of electronics, offering high-speed processing and low-cost data storage. The spin of electrons plays a crucial role in enabling such devices, with spin-transfer torque being a key phenomenon. However, recent advancements in spin-orbit torque (SOT) have introduced new possibilities for spintronic devices. Research has shown that the spin Hall
Exposure to mercury (Hg) is notoriously known for its extreme neurotoxic effects, even to those who study mercury compounds themselves. Renowned physicist Michael Faraday experienced firsthand the detrimental consequences of prolonged exposure to mercury vapors, which forced him to halt his research due to deteriorating health. Another tragic example is lab chemist Karen Wetterhahn, who
In today’s world, communication infrastructure plays a critical role in enabling the quick and easy sharing of information. However, while urban African communities have benefited from this connectivity, the same cannot be said for rural areas. In these regions, where resources are scarce and investment opportunities are limited, residents face significant challenges in reliable communication.
Ultra-intense ultrashort lasers have expanded their scope of applications over the years, spanning across various fields such as basic physics, national security, industrial services, and healthcare. These lasers have proven to be an invaluable tool for research in strong-field laser physics, particularly in areas such as laser-driven radiation sources, laser particle acceleration, vacuum quantum electrodynamics,
Researchers at Case Western Reserve University are making significant strides in their efforts to convert waste into fuels and other valuable products using energy-efficient and renewable processes. Their focus lies specifically in tackling the challenge of converting carbon dioxide (CO2), a prominent greenhouse gas, into useful chemicals through the use of electricity. Converting CO2 into
Researchers at Vanderbilt University have uncovered a fascinating link between gut microbes and weight gain, shedding light on the potential impact of early exposure to antibiotics on childhood obesity. By feeding young mice a high or low fat diet, with or without antibiotics, the team observed that mice on a high fat diet and exposed
After successfully landing on the Moon, the next frontier for humanity is Mars. However, this ambitious endeavor presents a whole new set of challenges in the realm of space travel. In an exciting development, NASA recently announced a major breakthrough in rocket engine technology that could propel us to the Red Planet at unprecedented speed.
When it comes to atoms, there are three key components: protons, neutrons, and electrons. While electrons are considered fundamental particles, protons and neutrons are composite particles made up of up and down quarks. Protons consist of two ups and one down quark, while neutrons have two downs and one up quark. However, due to the
