Efforts to map atomic-scale chemistry at low doses with minimal noise using electron microscopes are fundamentally limited by inelastic ***,fused multi-modal electron microscopy offers high signal-to-noise ratio(SNR)recovery of material chemistry at nano-and atomic-resolution by coupling correlated information encoded within both elastic scattering(high-angle annular dark-field(HAADF))and inelastic spectroscopic signals(electron energy loss(EELS)or energy-dispersive x-ray(EDX)).By linking these simultaneously acquired signals,or modalities,the chemical distribution within nanomaterials can be imaged at significantly lower doses with existing detector *** many cases,the dose requirements can be reduced by over one order of *** high SNR recovery of chemistry is tested against simulated and experimental atomic resolution data of heterogeneous nanomaterials.

One method of treating diabetic foot ulcers (DFU), especially superficial and deep ulcers, is by using a wound scaffold in the form of a hydrogel. Sericin derived from silkworm cocoons is a promising hydrogel material candidate. Sericin protein is a part of silk that is rarely used but has the potential for biocompatibility, biological activities, and is easy to process. One of the drawbacks of sericin hydrogels is their lower mechanical properties. Therefore, sericin was composited with PVA through the freeze-thaw technique to obtain a hydrogel with good stability. Sericin/PVA hydrogel was prepared with variations in solution concentration and the ratio of PVA and sericin. It resulted in the hydrogel with interconnected pore structures. Hydrogel-based wound dressings are often chosen for the treatment of DFU in combination with herbal extract. Moringa oleifera leaves extract was embedded into sericin/PVA hydrogel as a substance to heal DFU. In this study, the morphological and structural properties of sericin/PVA hydrogels were evaluated. The micro-CT imaging analysis was done to confirm hydrogel structure and calculate its porosity percentage. The compression test and hyperelasticity validity test were done to validate the hyperelastic material model.

The periodic undulation of a molten track’s height profile in laser-based powder bed fusion of metals(PBF-LB/M)is a commonly observed phenomena that can cause defects and building failure during the manufacturing *** a quantitative analysis of such instabilities has not been fully established and so here we used Rayleigh–Plateau theory to determine the stability of a single molten track in PBF-LB/M and tested it with various processing conditions by changing laser power and beam *** analysis discovered that normalized enthalpy,which relates to energy input density,determines whether a molten track is initially unstable and if so,the growth rate for the ***,whether the growth rate ultimately yields significant undulation depends on the melt duration,estimated by dwell time in our experiment.
