| Unveiling what governs crystal growth Posted: 26 May 2021 03:58 PM PDT Crystals are wonders of nature and science with important applications in electronics and optics. Scientists have new insights into how gallium nitride crystals grow. Gallium nitride crystals are in wide use in light-emitting diodes (LEDs) and may form transistors for high-power switching electronics to make electric grids more energy efficient and smarter. |
| Study of promising photovoltaic material leads to discovery of a new state of matter Posted: 26 May 2021 12:01 PM PDT Researchers have gained new insight into the workings of perovskites, a semiconductor material that shows great promise for making high-efficiency, low-cost solar cells and a range of other optical and electronic devices. |
| Scientists find solution to measure harmful plastic particles in human sewage Posted: 26 May 2021 10:21 AM PDT Scientists have got up close and personal with human sewage to determine how best to measure hidden and potentially dangerous plastics. |
| Posted: 26 May 2021 10:21 AM PDT Researchers have used 'swarm learning' - a novel, artificial intelligence technology - to detect blood cancer, lung diseases and COVID-19 in data stored in a decentralized fashion. |
| Slender robotic finger senses buried items Posted: 26 May 2021 10:21 AM PDT Researchers developed a 'Digger Finger' robot that digs through granular material, like sand and gravel, and senses the shapes of buried objects. The technology could aid in disarming buried bombs or inspecting underground cables. |
| How the mold influences a chocolate bar's crystalline structure Posted: 26 May 2021 10:21 AM PDT When enjoying a chocolate bar, most people don't think about how the molecules within it are organized. But different arrangements of the fats in chocolate can influence its taste and texture. Now, researchers have found that the side of a chocolate bar facing the mold has a more orderly crystalline structure than the side facing air, knowledge that might help chocolatiers produce tastier confections, the researchers say. |
| Universal travel pattern across four continents Posted: 26 May 2021 08:56 AM PDT New research confirms people visit places more frequently when they have to travel shorter distances to get there. The study establishes a 'visitation law' and could help in urban planning. |
| Journey of PFAS in wastewater facilities highlights regulation challenges Posted: 26 May 2021 08:55 AM PDT Researchers have conducted two of the first studies in New England to collectively show that toxic human-made chemicals called PFAS (per-and polyfluoroalkyl substances), found in everything from rugs to product packaging, end up in the environment differently after being processed through wastewater treatment facilities -- making it more challenging to set acceptable screening levels. |
| The world's smallest fruit picker controlled by artificial intelligence Posted: 26 May 2021 08:55 AM PDT Inspired by insects that suck nutrients directly from plant veins, physicists have studied whether valuable chemical substances can be harvested directly from the cells of plants. Using a harvester measuring only a few microns, they have now achieved a technological breakthrough. |
| Warm ice may fracture differently than cold ice Posted: 26 May 2021 08:55 AM PDT Researchers have found strong evidence that warm ice - that is, ice very close in temperature to zero degrees Celsius - may fracture differently than the kinds of ice typically studied in laboratories or nature. A new study takes a closer look at the phenomenon. |
| A new 'gold standard' compound for generating electricity from heat Posted: 26 May 2021 08:54 AM PDT Researchers show in a new study that a single material, a layered crystal consisting of the elements rhenium and silicon, turns out to be the gold standard of transverse thermoelectric devices. |
| Understanding of invisible but mighty particles in Earth's radiation belts Posted: 26 May 2021 06:31 AM PDT Tiny charged electrons and protons which can damage satellites and alter the ozone have revealed some of their mysteries to scientists. |
| Small modular reactors competitive in Washington's clean energy future Posted: 26 May 2021 06:31 AM PDT A new report finds small modular reactors could provide competitively priced electricity in Washington state's future electricity market. |
| As water sources become scarce, understanding emerging subsurface contaminants is key Posted: 25 May 2021 07:16 AM PDT Researchers have developed a variety of models that can help assess how emerging contaminants disperse, dissolve and ultimately impact water quality and the resilience of aquifers. |
| Newly discovered enzymes are not heavy metal fans Posted: 25 May 2021 07:16 AM PDT Researchers have discovered a new group of carbonic anhydrase enzymes that do not require any metal ions for their activity, which improves our knowledge of the global carbon cycle and may be applicable to artificial photosynthesis. |
| Harnessing next generation sequencing to detect SARS-CoV-2 and prepare for the next pandemic Posted: 25 May 2021 05:43 AM PDT Researchers have designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, could be adapted to many more pathogens. |
