What Is The Torque Equation?

The equation for torque can be represented with the following equation: τ = F * rsin(θ). T is the torque vector while F is the given force, r is the moment arm’s length, and θ is the angle found between […]

Microalgae: The Green Mines For Fueling The Future And Mitigating Heavy Metals

The energy crisis, water shortage, and pollution are among the major challenges confronting sustainable environmental existence. Renewable energy derived from sustainable feedstocks can reduce the load on fossil fuels and curb greenhouse gas (GHG) emissions. Biofuels, particularly bioethanol and biodiesel, […]

COF-1 As A 2-D Material With Promising Applications

The quest for two-dimensional (2D) materials, starting with graphene in 2004, remains strong. While graphene retains the title of strongest solid, intense research has shown that it is not suited for every use. For example, turning off the current flowing […]

Visualizing Layer-By-Layer Growth Of LaTiO3 On SrTiO3

The atomic stacking sequence of materials known as the complex oxides can be critical to material properties. For instance, the oxide YBa2Cu3O7 is superconducting only when the stacking sequence is precisely Y-CuO2-BaO- CuO-BaO-CuO2. One can test this by growing an […]

What Do Brakes, Basketball Shoes, And Earthquakes Have In Common?

The squeaking sound that basketball players produce as their shoes slide over the floor is a consequence of stick-slip motion: as the basketball shoe successively sticks and slips at a high frequency and over a short distance, the interface periodically […]

Remarkable Emissions Of Nitrated Phenols From Residential Coal Combustion

Coal, one of the most important energy resources, is widely used around the world in power generation, industrial production, household cooking, heating, and so on. In China, 91 Tg coal was used in the residential sector for cooking and heating […]

Bending (But Not Breaking) The Second Law Of Thermodynamics Using A “Thermal Inductor”

The fundamental laws of thermodynamics The first law of thermodynamics is widely known, even outside scientific classrooms, because it introduces “heat” into the balance of energy conservation. In a simplified version, we can say that the sum of the heat […]

New Insights Into The Aqueous Chemistry Of Tetravalent Cerium

The prediction of cerium aqueous speciation is relevant in many research fields. Indeed, cerium compounds are used for many industrial applications (e.g. in flat-screen TVs, low-energy light bulbs, and floodlights), which may require the control of cerium aqueous chemistry for […]

How Do Crystals Form?

Crystallization is a rare case of a phenomenon which is familiar in everyday life and yet is the focus of intensive research at the forefront of physics, chemistry, and materials science. Common examples of crystallization are the formation of snowflakes […]

A Novel Shuttle-Like FeP@C Hybrid Electrode Material For High-Performance Lithium-Ion Batteries

With the increasing attention to environmental problems and the strong demand for clean and sustainable energy, it is becoming an important goal worldwide to manufacture an advanced energy storage device with high energy density, high power density, and long cycling […]
