Although the temperature-dependent decline in aromatic hydrogenation rates has often been attributed to site blocking by strongly adsorbed species, direct experimental evidence for the formation and evolution of these species has remained limited. Here, TOL hydrogenation over Ni/Al2O3 and Pt/Al2O3 was investigated using kinetic measurements, temperature-programmed surface reaction (TPSR) with D2, temperature-programmed reduction coupled with mass spectrometry (TPR-MS), H2 regeneration tests, gas-switching experiments, and Raman spectroscopy. Over Ni/Al2O3, TOL was selectively hydrogenated to methylcyclohexane at 120 °C, whereas the TOL consumption rate decreased markedly at 180 °C under conditions far from thermodynamic equilibrium. A similarly suppressed hydrogenation regime was observed over Pt/Al2O3 at approximately 250–350 °C, demonstrating a strong dependence on the catalyst metal. Over Ni/Al2O3 at 180 °C, the apparent reaction order with respect to H2 exceeded 2, and the initial activity was fully restored by treatment under H2 at 600 °C, indicating that H2 participated in both TOL hydrogenation and the removal of persistent site-blocking species. During TPR-MS, TOL and benzene evolved from approximately 200 °C, supporting preservation of the six-membered carbon-ring framework in retained adsorbates. CH4 evolution began above approximately 250 °C and persisted beyond 500 °C, consistent with methyl-derived fragments remaining after benzene release and undergoing subsequent hydrogenative removal. At 300 °C over Ni/Al2O3, hydrodemethylation became the dominant reaction pathway. Gas-switching experiments from TOL/H2 to H2 produced a transient CH4 peak, indicating the accumulation of hydrogenatable carbonaceous species, and Raman spectroscopy confirmed the presence of disordered graphite-like carbon. These findings provide experimental support for kinetic inhibition by persistent ring-containing adsorbates at intermediate temperatures and associate higher-temperature hydrodemethylation with carbon accumulation and graphite-like carbon formation.","PeriodicalId":61,"journal":{"name":"The Journal of Physical Chemistry C","volume":"16 1","pages":""},"PeriodicalIF":4.126,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combining single-crystal X-ray diffraction (SCXRD) and Raman spectroscopy, we found a reversible pressure-induced phase transition between 1.05 and 1.8 GPa, from monoclinic (P21) to triclinic (P1). XRD analysis reveals an abrupt unit cell volume reduction of approximately 5.50%, indicating a significant structural reorganization to accommodate the applied stress. High-pressure Raman spectra corroborate these findings, exhibiting discontinuities in the ω(P) slopes, the emergence of a new lattice mode, and various other bands associated with internal modes at 1.8 GPa, reflecting the symmetry reduction. Density Functional Theory (DFT) calculations using the Generalized Gradient Approximation-Tkatchenko-Scheffler (GGA-TS) functional were employed to obtain accurate vibrational assignments and validate the experimental lattice parameters. Furthermore, Hirshfeld surface and crystal void analyses demonstrate that the transition is driven by a redistribution of intermolecular contacts and the strengthening of the hydrogen-bond network, particularly N–H···Cl and C–H···Cl interactions. The data analysis yields a bulk modulus (K0 = 14.68 GPa), which indicates that LHMED is a soft molecular crystal. Our results show that the presence of a methyl ester group increases structural flexibility compared to nonmethylated l-histidine, leading to a conformational transition at lower pressure. Upon decompression, SCXRD showed that the original monoclinic phase is mostly recovered, highlighting remarkable crystalline memory and structural reversibility; however, Raman spectroscopy measurements during the pressure-release process, down to 0.7 GPa, revealed slight hysteresis, as indicated by subtle variations in some vibrational modes.","PeriodicalId":61,"journal":{"name":"The Journal of Physical Chemistry C","volume":"86 1","pages":""},"PeriodicalIF":4.126,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the optical forces acting on individual nanoparticles are insufficient to achieve stable trapping, they induce a bias in Brownian diffusion toward the laser focus, resulting in the local accumulation of the nanoparticles. This optically biased diffusion presents a novel mechanism for regulating molecular assembly in two-dimensional membrane systems and provides a means to probe the lateral dynamics of membrane-associated biomolecules. In this study, we investigated the particle dynamics of quantum-dot-labeled streptavidin (QD-SA) bound to a supported lipid bilayer (SLB) in an optical trap. Single-particle tracking analysis of fluorescence images revealed that the diffusion coefficient of individual QD-SA particles on the SLB showed no systematic increase or decrease with increasing laser power, indicating that the optical forces were insufficient for the stable trapping of single nanoparticles on a two-dimensional membrane. In contrast, both the average transit time and the number of QD-SA particles within the laser focal spot tended to increase with increasing laser power. These results indicate that optical forces induce the biased diffusion of QD-SA particles toward the focal spot, leading to the local accumulation of multiple particles rather than the stable trapping of a single particle on the SLB. These findings demonstrate that the biased diffusion induced by optical forces can be exploited to control the spatiotemporal organization of membrane-associated molecules on the lipid bilayers.","PeriodicalId":61,"journal":{"name":"The Journal of Physical Chemistry C","volume":"11 1","pages":""},"PeriodicalIF":4.126,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
