Investigational magnetic device shrinks glioblastoma in first-in-world human test

Houston Methodist Neurological Institute researchers from the department of neurosurgery shrunk a deadly glioblastoma tumor by more than a third using a helmet generating a noninvasive oscillating magnetic field that the patient wore on his head while administering the therapy…

Removing the lead hazard from perovskite solar cells

“The solar energy-to-electricity conversion of perovskite solar cells is unbelievably high, around 25%, which is now approaching the performance of the best silicon solar cells,” says Professor László Forró at EPFL’s School of Basic Sciences. “But their central element is…

Methodical architectural design for ideal wind energy production

Systematic Architectural Design for Optimal Wind Energy Generation is an essential reference for students of architecture at all levels, professional architects, as well as readers interested in green building design, renewable energy, and sustainability studies that pave the way towards…

Beyond 5G: Wireless communications may get a boost from ultra-short collimating metalens

Screens may be larger on smartphones now, but nearly every other component is designed to be thinner, flatter and tinier than ever before. The engineering requires a shift from shapely, and bulky lenses to the development of miniaturized, two-dimensional metalenses.…

Cutting through noise for better solar cells

As society moves towards a renewable energy future, it’s crucial that solar panels convert light into electricity as efficiently as possible. Some state-of-the-art solar cells are close to the theoretical maximum of efficiency–and physicists from the University of Utah and…

Passing the COVID test in just five minutes

Researchers at Osaka University develop a new highly sensitive test for the SARS-CoV-2 virus that utilizes a fusion of artificial intelligence and nanopore technology which may enable rapid point-of-care testing for COVID

One step towards a daily-use deep UV light source for sterilization and disinfection

Researchers construct a gallium nitride optical microcavity with high reflectivity distributed Bragg reflectors to double the frequency of incoming light, which may be utilized for a safe and practical deep UV light source with bactericidal effects

Achieving UV nonlinearity with a wide bandgap semiconductor waveguide

The field of ultrafast nonlinear photonics has now become the focus of numerous studies, as it enables a host of applications in advanced on-chip spectroscopy and information processing. The latter in particular requires a strongly intensity-dependent optical refractive index that…

‘Floating’ microgrids: Optimizing naval ships’ power systems

Lehigh University electrical and computer engineering researcher Wenxin Liu awarded two ONR grants–totaling $900,000–for algorithmic design and hardware experimentation that could lead to advances in civilian microgrid technology

Detecting skin disorders based on tissue stiffness with a soft sensing device

By putting a piece of soft, strain-sensing sheet on the skin may be able to detect skin disorders non-invasively and in real-time very soon. A research team co-led by a scientist from City University of Hong Kong (CityU) has designed…

The dark matter particle explorer has measured high-precision cosmic ray helium energy spectrum

Dark Matter Particle Explorer (DAMPE) Collaboration directly observed a spectral softening of helium nuclei at about 34TeV for the first time. This work was based on measurements data of the helium spectrum with kinetic energies from 70 GeV to 80…

Nanofibrous filters for PM2.5 filtration

In a paper published in NANO , the author reviewed many kinds of nanofibrous filters including the component, preparation process, and application performances to provide directional guidance for improvement of the air purification field. Poor air quality is worldwide recognized…

Scientists overhear two atoms chatting

How materials behave depends on the interactions between countless atoms. You could see this as a giant group chat in which atoms are continuously exchanging quantum information. Researchers from Delft University of Technology in collaboration with RWTH Aachen University and…
