(via sciencedaily.com) Original source A fabrication process can produce self-heating microfluidic devices in one step using a multimaterial 3D printer. These devices, which can be made rapidly and cheaply in large numbers, could help clinicians in remote parts of the world detect diseases without expensive lab equipment.
Published Eco-friendly technologies for plastic production and biodegradation?
(via sciencedaily.com) Original source A new article covering an overview and trends of plastic production and degradation technology using microorganisms has been published. Eco-friendly and sustainable plastic production and degradation technology using microorganisms as a core technology to achieve a plastic circular economy was presented.
Published New conductive, cotton-based fiber developed for smart textiles
(via sciencedaily.com) Original source A single strand of newly developed fiber has the flexibility of cotton and the electric conductivity of the polymer, polyaniline. The new material has shown good potential for wearable e-textiles. The researchers tested the fibers with a system that powered an LED light and another that sensed ammonia gas. While intrinsically conductive, polyaniline is brittle and by itself, cannot be made into a fiber for textiles. To solve this, the researchers dissolved cotton cellulose from recycled t-shirts into a solution and the conductive polymer into another separate solution.
Published Chance twists ordered carbon nanotubes into 'tornado films'
(via sciencedaily.com) Original source Scientists have developed two new methods to create ordered carbon nanotube films with either a left- or right-handed chiral pattern.
Published Researchers combine biopolymers derived from the ocean to replace synthetic plastic films
(via sciencedaily.com) Original source Crustacean and seaweed materials combined in a unique way could provide a sustainable alternative to plastic films.
Published Polyethylene waste could be a thing of the past
(via sciencedaily.com) Original source Experts have developed a way of using polyethylene waste (PE) as a feedstock and converted it into valuable chemicals, via light-driven photocatalysis. PE is the most widely used plastic in the world including for daily food packaging, shopping bags and reagent bottles, and the researchers say that while recycling of PE is still in early development, it could be an untapped resource for re-use.
Published Hybrid device significantly improves existing, ubiquitous laser technology
(via sciencedaily.com) Original source Researchers have developed a chip-scale laser source that enhances the performance of semiconductor lasers while enabling the generation of shorter wavelengths. This pioneering work represents a significant advance in the field of photonics, with implications for telecommunications, metrology, and other high-precision applications.
Published First observation of structures resulting from 3D domain swapping in antibody light chains
(via sciencedaily.com) Original source Antibodies hold promise as therapeutic agents. However, their tendency to aggregate poses significant challenges to drug development. In a groundbreaking study, researchers now provide novel insights into the structure formed due to 3D domain swapping of the antibody light chain, the part of the antibody contributing to antigen binding. Their findings are expected to lead to improvements in antibody quality and the development of novel drugs.
Published A fork in the 'rhod': Researchers unveil comprehensive collection of rhodamine-based fluorescent dyes
(via sciencedaily.com) Original source After more than a decade of developing fluorescent probes, a research team has now released the culmination of their years of work: A comprehensive collection of rhodamine-based dyes, the novel chemistry they developed to synthesize them and insights that provide a roadmap for designing future probes.
Published Polaritons open up a new lane on the semiconductor highway
(via sciencedaily.com) Original source On the highway of heat transfer, thermal energy is moved by way of quantum particles called phonons. But at the nanoscale of today's most cutting-edge semiconductors, those phonons don't remove enough heat. That's why researchers are focused on opening a new nanoscale lane on the heat transfer highway by using hybrid quasiparticles called 'polaritons.'
Published Ancient stars made extraordinarily heavy elements
(via sciencedaily.com) Original source How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the periodic table found naturally on Earth. The finding deepens our understanding of element formation in stars.
Published Catalyst for electronically controlled C--H functionalization
(via sciencedaily.com) Original source Scientists chipping away at one of the great challenges of metal-catalyzed C--H functionalization with a new method that uses a cobalt catalyst to differentiate between bonds in fluoroarenes, functionalizing them based on their intrinsic electronic properties. And their method is fast -- comparable in speed to those that rely on iridium.
Published Bowtie resonators that build themselves bridge the gap between nanoscopic and macroscopic
(via sciencedaily.com) Original source Two nanotechnology approaches converge by employing a new generation of fabrication technology. It combines the scalability of semiconductor technology with the atomic dimensions enabled by self-assembly.
Published Chemists create organic molecules in a rainbow of colors
(via sciencedaily.com) Original source Chemists have now come up with a way to make molecules known as acenes more stable, allowing them to synthesize acenes of varying lengths. Using their new approach, they were able to build molecules that emit red, orange, yellow, green, or blue light, which could make acenes easier to deploy in a variety of applications.
Published Diamonds and rust help unveil 'impossible' quasi-particles
(via sciencedaily.com) Original source Researchers have discovered magnetic monopoles -- isolated magnetic charges -- in a material closely related to rust, a result that could be used to power greener and faster computing technologies.

Published New theory unites Einstein's gravity with quantum mechanics
(via sciencedaily.com) Original source The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a quantum theory of gravity, string theory and loop quantum gravity. But a new theory challenges that consensus and takes an alternative approach by suggesting that spacetime may be classical -- that is, not governed by quantum theory at all.
Published Quantum physics: Superconducting Nanowires Detect Single Protein Ions
(via sciencedaily.com) Original source An international research team has achieved a breakthrough in the detection of protein ions: Due to their high energy sensitivity, superconducting nanowire detectors achieve almost 100% quantum efficiency and exceed the detection efficiency of conventional ion detectors at low energies by a factor of up to a 1,000. In contrast to conventional detectors, they can also distinguish macromolecules by their impact energy. This allows for more sensitive detection of proteins and it provides additional information in mass spectrometry.
