Correcting HIRES radial velocities for small systematic errors
The HIRES spectrograph, mounted on the $10$-m Keck-I telescope, belongs to a small group of radial-velocity (RV) instruments that produce stellar RVs with long-term precision down to $\sim1$ ms$^{-1}$. In $2017$, the HIRES team published $64,480$ RVs of $

Resolving the Structural Duality of Graphene Grain Boundaries
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Geo-Intelligent Solutions for Urban Heat Island (UHI) Detection and Mitigation Framework
Urban areas often experience elevated temperatures compared to their rural surroundings, leading to the phenomenon of the Urban Heat Island (UHI) effect. This is a growing environmental concern driven by rapid urbanisation, turning cities into heat traps.

A new method of correcting radial velocity time series for inhomogeneous convection
Magnetic activity strongly impacts stellar RVs and the search for small planets. We showed previously that in the solar case it induces RV variations with an amplitude over the cycle on the order of 8 m/s, with signals on short and long timescales.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Modern vehicular systems rely heavily on suspension performance for ride comfort, handling stability, and safety. Conventional passive suspensions, while common, cannot adapt to changing road conditions. Active suspension systems overcome this limitation

Phonon Engineering in Ultrathin Sn Films
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the
