Rare earth orthoferrites demonstrate great application potentials in spintronics and optical devices due to their multiferroic and magnetooptical properties. In RFeO3, magnetic R3+ undergo a spontaneous spin reorientation in a temperature range determined by R (rare earth), where the magnetic structure changes from Γ2 to Γ4. The b-axis component of their magnetic moment, Mb, is reported in numerous neutron diffraction studies to remain zero at all temperatures. More sensitive magnetometer measur...

The evolution of nanoscale properties is measured during the thermally triggered curing of an industrial epoxy adhesive. We use x-ray photon correlation spectroscopy (XPCS) to track the progression of the curing reaction through the local dynamics of filler particles that reflect the formation of a thermoset network. Out-of-equilibrium dynamics are resolved through identification and analysis of the intensity–intensity autocorrelation functions obtained from XPCS. The characteristic time scale a...

We describe magneto-, baro-, and elastocaloric effects (MCEs, BCEs, and eCEs) in materials, which possess both discontinuous (first-order) and continuous (second-order) magnetic phase transitions. Our ab initio theory of the interacting electrons of materials in terms of disordered local moments has produced explicit mechanisms for the drivers of these transitions, and here, we study associated caloric effects in three case studies where both types of transition are evident. Our earlier work had...

A fiber Bragg grating (FBG) is one of the most common and widely used fiber optic sensors. One main issue when using a FBG-based sensor is that it is simultaneously sensitive to both the strain and the temperature, and compensation for the temperature and strain effects is necessary to measure these parameters. The available compensation techniques mean that the interrogation of FBG sensor systems is complex and make sensor networks bulky by increasing the number of sensors. Several of these com...

Mesoporous silica nanoparticles/polymer hybrid materials were prepared via metal-free surface-initiated atom-transfer radical polymerization (SI-ATRP). Self-synthesized mesoporous SBA-15 with surface hydroxyl groups was modified with (3-aminopropyl)-triethoxysilane, followed by anchoring of the ATRP initiator α-bromoisobutyryl bromide onto the surface via amide reaction. The SI-ATRP of methyl methacrylate was then carried out with fluorescein (FL) as a photocatalyst and trimethylamine (TEA) as a...

Regular resonance modes in GaN-based polygonal microdisks are investigated by simulations and photoluminescence measurements. Based on a standard GaN-based blue light emitting diode wafer on a Si substrate, hexagonal and octagonal microdisks with similar dimensions are fabricated. Whispering gallery-like modes and Fabry–Perot modes in the polygonal microcavities are pictured by theoretical calculations. All resonant modes in the polygonal microdisks are confined along regular and isolated orbits...

Defect-driven properties of lead-free piezoelectric materials have become the focus of research as a result of in-depth investigations into such materials. Here, we pay special attention to the conductivity mechanism of 0.91K0.5Na0.5NbO3–0.05Ag1 − xNaxSbO3–0.04Bi0.5Na0.5ZrO3 ceramics. The charge carrier concentration induced by defects, which exerts an effect on conductivity, displays different mechanisms under different temperatures. By analyzing the energy band diagram, we identify the carrier...
