1. Protoplanetary cores drove chondrule formation 

   Ali-Dib, Mohamad; Walton, Craig (2025)

   MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY

   Chondrules are small spherical objects that formed at high temperatures early in the history of the Solar System. The key compositional characteristics of chondrules may be well explained by high gas pressures in their formation environment. However, such high gas pressures are widely considered astrophysically unreasonable. Here, we propose that chondrules were formed via the processing of dust grains in the dust-rich envelopes of planetary ...

2. Regularity of Unconstrained <i>p</i>-harmonic Maps from Curved Domain and Application to critical <i>p</i>-Laplace Systems 

   Martino, Dorian (2025)

   POTENTIAL ANALYSIS

   Given p >= 2 and a map g:Bn(0,1)-> Sn++, where Sn++ is the group of positively definite matrices, we study critical points of the following functional: v is an element of W1,pBn(0,1);RN integral Bn(0,1)|del v|gpdvolg=integral Bn(0,1)g alpha beta(x)partial derivative alpha v(x),partial derivative beta v(x)p2detg(x)dx. We show that if g is uniformly close to a constant matrix, then v is locally H & ouml;lder-continuous. If g is H & ...

3. Understanding the Structure of Protonated Box Ligands: Insights from Spectroscopy and Computational Studies 

   Gorbachev, Vladimir; van Tetering, Lara; Martens, Jonathan; et al. (2025)

   Helvetica Chimica Acta

   Protonation and tautomerization significantly impact the conformational landscape and non-covalent interactions in bis(oxazoline) (BOX) ligands, which are crucial for their applications in catalysis. These interactions influence properties such as binding affinity and catalytic efficiency. While tautomerization has been reported for neutral BOX ligands, its role in protonated forms remains less understood. Here we report the structural ...

4. Observation of polarization density waves in SrTiO₃ 

   Orenstein, Gal; Krapivin, Viktor; Huang, Yijing; et al. (2025)

   Nature Physics

   The nature of the incipient ferroelectric transition in SrTiO3 has been a long-standing puzzle in condensed matter physics. One explanation involves the competition between ferroelectricity and an instability characterized by the mesoscopic modulation of the polarization. These polarization density waves, which should intensify near the quantum critical point, break local inversion symmetry and are difficult to characterize with conventional ...

5. The ultra-low material budget GEM-based TPC for tracking with VMM3a readout 

   Garcia, F.; Floethner, K. J.; Amato, A.; et al. (2025)

   Journal of Instrumentation

   The Gaseous Electron Multiplier-based Time Projection Chamber (GEM-TPC) in TWIN configuration for particle tracking has been consolidated after extensive investigations in different facilities to study its tracking performance. The most attractive feature of this detector is its ultra-low material budget, which is 0.28% X/X0 and can be further reduced by decreasing the thickness of the gas traversed by the incident particles. Thus, it ...
