Carbyne - an unusual form of carbon

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.
 
 

Advanced cantilever-based techniques for virus research

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.

 
 

MBenes - boron-analogues of MXenes - enable efficient electrochemical synthesis of ammonia

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.

 
 

Researchers reveal structural transformation of highly active MOF electrocatalysts during oxygen evolution reaction

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.
 
 

Making better quantum devices

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.
 
 

Quantum tunneling pushes the limits of self-powered sensors

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.
 
 

Mastering the art of nanoscale construction to breathe easy and bust fraud

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.
 
 

Metal-organic frameworks become flexible

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.
