Microbubbles show great promise in clinical application as diagnostic ultrasound contrast agents. Chabouh and coworkers characterize the swimming motion of these microbubbles under cyclic external pressures through buckling. The results provide guidance to design ultrasound contrast agents with accurate mobility control.

Existing indices available to quantify the influence of moisture sources on air humidity and temperature are limited in their ability to accurately describe dynamic phenomena. Jiale Hu and colleagues propose two dynamic indices and use them to experimentally evaluate the dynamic indoor environment change performance of a humidifier.

Zhelyeznyakov and coworkers present a data-free physics-informed neural network to model and optimize the electromagnetic field distribution of large-scale ( ~ 1 mm in diameter) optical meta-lenses. This simplified method can speed up the design of large aperture meta-optics.

Tongyang Xu and Izzat Darwazeh use machine learning to identify a non-Nyquist waveform with high spectral efficiency, which is then practically validated with over-the-air image transmission using a hardware communication link. Waveforms such as these and the resulting spectral resource saving could be useful for enabling future 6G communications systems.

Johnson and Fiss successfully integrate a megawatt-scale latent heat storage system into a cogeneration thermal power plant to produce superheated steam. The data obtained demonstrates the feasibility of utilising latent heat for superheated steam in industry.

Nonlinear modulation within silicon microring modulators hinders the data transmission at optical interconnections. A neural network, proposed by Fangchen Hu, Yuguang Zhang, Hongguang Zhang and coworkers, can effectively mitigate the nonlinearity to accelerate the transmission speed. The results provide insights to integrate AI techniques to facilitate ultrahigh-speed silicon microring modulator design.

Carlos Rossa reports measurements exploring the impact of wind speed on the performance of photovoltaic modules. Data reveal that wind speed can increase the temperature dispersion in a module field, which can lead to unexpected losses. The findings could be used to optimise the performance prediction of photovoltaic fields.

Böhnert and colleagues demonstrate the weighted spin torque nano-oscillator, a spintronic circuit, as a basic programmable computing unit for neuromorphic computing systems. This circuit connects multiple spintronic devices with different functionalities in one circuit using a single fabrication process, which paves ways to fabricate more complex neuromorphic computing systems.

Microbubbles show great promise in clinical application as diagnostic ultrasound contrast agents. Chabouh and coworkers characterize the swimming motion of these microbubbles under cyclic external pressures through buckling.

Yu and Ouderji compare the thermodynamic performance of the flexible heat pump cycle with other performance enhancing cycles using a unified approach. Their analysis uncovers the working mechanisms and refrigerant characteristics that improve system performance, guiding heat pump optimisation.

On International Women in Engineering Day, we outline the ways that Communications Engineering supports the equitable inclusion of women in our publishing activities. We also suggest ways in which researchers can be supporters of diversity and inclusion when publishing their own research.

Today we celebrate the first anniversary of the launch of Communications Engineering. We reflect on our progress and welcome in the second year by announcing some new projects and content.

Professor Inge Herrmann offers her insights into building commercialisable research projects and the transition into spin-off activity.

A recent publication in Proceedings of the National Academy of Sciences describes a fluid-based building interface to reduce energy use for heating, cooling and lighting by selectively tuning light absorption and dispersion. Models showed that this system could reduce the annual energy consumption by up to 43% compared to existing technologies.

Dr. Robert Lang describes how he approaches building origami structures and offers thoughts on the future of origami research.

Dr. Emanuela Bosco describes her research into mechanical processes which affect the stability and longevity of historical artifacts.
