molecular electronics scientists shatter 'impossible' record




an international research team that includes university of central florida professor enrique del barco, damien thompson of the university of limerick and christian a. nijhuis of the national university of singapore has cracked an important limitation that for nearly 20 years has prevented the practi...



diy synthesizer features 3d-printed keyboard – synthtopia




the f0 is a minimalist, analog, square wave synthesizer with custom 3d-printed piano keys.here’s a quick demo of the diy synth in action:the heart of the f0 is a voltage controlled oscillator (vco) from a cd4046 chip. a 9v battery feeds a 5v regulator to create a constant reference voltage, which ...



erica synths fusion vcf v2 & fusion vca v2 – synthtopia




erica synths’ fusion vca & vcf vacuum-tube eurorack modules are now available.the 24db/12db fusion vcf is their take on the four pole lowpass filter. each side of double triode drives signal between 2nd and 3rd stage of the filter, while germanium diodes are used to limit output signal.they say th...



'face-sensing' headsets show your real-life expressions in vr




mindmaze says the mask is easy to integrate into existing products. the setup consists of eight diodes embedded in the foam cushion that's used in most headsets, and they read electrical impulses and muscle activity from your face. that data is analyzed with a machine-learning algorithm that determi...

perovskite edges can be tuned for optoelectronic performance




in the eternal search for next generation high-efficiency solar cells and leds, scientists at los alamos national laboratory and their partners are creating innovative 2d layered hybrid perovskites that allow greater freedom in designing and fabricating efficient optoelectronic devices. industrial a...



photonic hypercrystals are now a reality and light will never be the same




in 2014, researchers  predicted the theoretical existence of a strange new material that altered the interaction between light and matter. the material, dubbed photonic hypercrystal, has now become a reality.researchers at the city college of new york (ccny) say they have actually created some, ...



a self-solving puzzle for organic molecules




co-existence of crystalline heteromolecular structures on metal surfaces: the figure shows two different crystalline structures (back right and front left) with a disordered area in between that only contains the repulsive molecular species. the sizes of the occupied areas can be altered (even at a ...

the exciting future of light energy




excitons are the reason we see light and colour. credit: university of melbournein a world of growing energy needs, and a global imperative to halt carbon emissions, a tiny 'quasiparticle' called an exciton could provide the answer to our problems. excitons are formed when light is absorbed by molec...



why would apple switch iphone 8 from lightning to usb-c?




transitions hurt but are also the way forward — so what could make lightning to usb-c worth the pain?iphone 8, or whatever apple decides to call the "10th anniversary iphone", has been rumored to contain all sorts of advanced technology, from distance charging to face and iris scanning. one of the...
