The optoelectronic properties of various carbon allotropes and nanomaterials have been well established, while the purely sp-hybridized carbyne remains synthetically inaccessible. Its properties have therefore frequently been extrapolated from those of defined oligomers. • Email to a friend • Atomic force microscopy (AFM) is one of the newer techniques available for virus research. AFM is a cantilever-based technique that utilizes a sharp tip to interrogate surfaces at resolutions well below the optical diffraction limit. Beyond imaging, AFM is also a powerful tool for nano-mechanical probing and nano-manipulation. One of the primary advantages of AFM is that it can operate on samples immersed in liquid. This empowers experiments on living cells at physiologically relevant conditions. • Email to a friend • The industrial production of ammonia mostly relies on the energy-intensive Haber-Bosch process, which causes significant environmental pollution. Researchers have now proposed that a class of 2D transition metal borides termed MBenes - the boron-analogues of MXenes - could be used as catalyst for ammonia production through electrochemical nitrogen reduction reaction (NRR). This work also provides a general design principle for further exploration of an even broader composition space of MBenes and other 2D NRR electrocatalysts. • Email to a friend • In this study, by using operando X-ray absorption spectroscopy and high-resolution transmission electron microscopy imaging, the researchers revealed a full landscape of the biphasic structural transformation occurring at the nodes inside Ni and Co bimetallic MOF during OER. • Email to a friend • Researchers have found that removing random doping in quantum electronic devices dramatically improves their reproducibility - a key requirement for future applications such as quantum-information processing and spintronics. • Email to a friend • The proposed device, with a theoretical operating energy budget less than 10 attojoules, uses a differential architecture to compensate for environmental variations and the device can retain sensed information for durations ranging from hours to days. • Email to a friend • A new way to arrange very small materials with perfect control could lead to more secure banknotes and passports, and quicker detection of harmful gas through a clever use of light. • Email to a friend • Researchers have used experiments and simulations to find out by what means MOFs can be rendered flexible and why: they tricked the system by using clever chemical manipulations to enable a variety of energetically similar arrangements in the crystalline order. • Email to a friend • |
