Summary: The instability of hot spots is a key limiting factor for the poor spectral reproducibility of SERS. Hot spots exhibit stability thresholds to excitation power, duration, and wavelength. Lowering the excitation power below the threshold or deliberately removing unstable hot spots can significantly improve the stability and reproducibility of SERS signals.

Summary: This study investigates the effect of plasmonic coupling on optomechanics using Brillouin light spectroscopy in a nanocomposite system of gold nanorods and polyvinyl alcohol. The intensity of inelastically scattered light on thermal phonons is found to be strongly influenced by the wavelength of the probing light, revealing different vibrational modes for resonant and off-resonant light.

Summary: In this study, a simple photolithographic method was demonstrated to generate highly sensitive SERS hot spot structures at desired positions. The solid-state dewetting of an Ag thin film using a continuous-wave laser resulted in the formation of closely packed assemblies of hemispherical Ag nanoislands with substantial plasmonic-field enhancement. These hot spot structures can be utilized as position-specific chemical-sensing elements in integrated analytical devices.

Summary: The study utilized Eu/Tb mixed-metal organic complexes as nano thermometers to probe the intrinsic temperature of MW-absorbing particles in MW fields, and derived an MW-irradiated energy transfer model to predict the extent of microscopic hot spots. The results show that the MW-induced temperature gradient can be enlarged by increasing MW intensity, dielectric loss, and particle size, while lowered by the increase in thermal conductivity and dielectric loss of the liquid.

Summary: The cytoskeleton is a supramolecular structure made up of interacting protein networks that play crucial roles in cell dynamics, including migration, division, and stress responses. Redox-related posttranslational modifications (PTMs) are emerging as key players in cytoskeletal regulation, as shown by a study on mild nitroxidative stress inducing changes in cytoskeletal protein organization and PTM profiles. High-resolution mass spectrometry identified 62 different PTMs in vimentin, actin, and tubulin, revealing a chain reaction with formation of numerous reactive species and activation of multiple signaling pathways.

Summary: In this study, a microporous deep silicon substrate coated with an optimum Au layer is used to achieve ultrahigh SERS enhancement for explosives trace detection. By scattering and coupling of short lived extended plasmons with localized ones, a microporous structure with quasi-periodicity provides an ultrahigh local optical field and achieves the ultrahigh SERS enhancement. The SERS activity and reproducibility of the substrate are tested using 4-ATP monolayer immobilized over the substrate, and different methods including peak absolute intensity and peak ratios are analyzed. The obtained enhancement factor for Raman signal is of the order of 10^6-10^7, which is explained by the existence of a 3D hot-spot network and the coupling between localized and extended plasmons. The coupling is confirmed by the Rabi splitting observed in the reflectivity dip. A 2-3 times reduction in signal variability is achieved using peak ratio analysis. The substrate is further applied for picric acid sensing, with detection limits of 7.48 nM and 2.87 nM based on peak height and ratio measurements, respectively. The results suggest that deep microporous silicon coated with a 200 nm Au layer over a large area is a promising candidate for SERS and sensing of ultra-trace amounts of chemicals.

Summary: By optimizing the geometry of gold nanoparticle cluster arrays (NCAs), especially increasing the density of intercluster hot spots, higher sensitivity in plasmon-enhanced spectroscopies can be achieved; the study indicates that larger analytes such as proteins are better leveraged on intercluster rather than interparticle hot spots, thus exhibiting higher sensitivity on NCAs with higher intercluster hot-spot densities.

Summary: A novel phosphor, red emitting Sr2CaTeO6:Sm3+, has been developed for white LEDs. The crystal structure and luminescence properties of this phosphor were systematically investigated. The Sr2CaTeO6:Sm3+ showed red emission peak at about 658 nm upon 407 nm near-UV excitation. It exhibited optimal performance with 2 mol% of Sm3+ doping and good thermal stability. Moreover, a near-UV pumped warm w-LED with Sr2CaTeO6:Sm3+, blue-emitting BAM:Eu2+, and green-emitting Lu-AG:Ce3+ phosphors was fabricated, indicating the promising application of Sr2CaTeO6:Sm3+ as a red-emitting material for pc-LEDs.

Summary: Ce3+-Tb3+-Eu3+ triply doped Ba3KPO4(SO4)(2) phosphors were synthesized and extensively studied. The luminescence properties, concentration effect, and energy transfer mechanism were investigated using photoluminescence spectra and decay curves. The luminescent color of the phosphors can be tuned by adjusting the energy transfer between different dopants. The newly synthesized phosphors can be used as a potential color converter with a large color gamut.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
