Abstract There is a need to develop inexpensive, lightweight, and flexible high‐performance triboelectric nanogenerators (TENGs) from renewable resources. Here, multifunctional cellulose filter paper (CFP)‐based TENG consisting of dielectric Ti 0.8 O 2 nanosheets (Ti NSs) conducting Ag nanoparticles (Ag NPs) prepared by simple dip coating method. The incorporation NSs onto the CFP significantly improves charge generation, while inclusion NPs provides an electrically conductive path for...
Zinc (Zn) is viewed as a promising anode material for large-scale secondary batteries. However, due to parasitic reactions and uneven Zn distribution during repeated stripping/plating cycles, anodes show inferior performance stability. To overcome such drawbacks, carboxymethyl cellulose (CMC) an artificial solid electrolyte interphase (ASEI) fabricated on sheet Zn-graphite composite anode. The roles of CMC-ASEI are examined using X-ray tomography, absorption near edge structure (XANES)...
Abstract Hypertension and osteoporosis are the major non-communicable diseases in elderly worldwide. Although clinical studies reported that hypertensive patients experienced significant bone loss likelihood of fracture, causal relationship between hypertension has been elusive due to other confounding factors associated with these diseases. In this study, spontaneously rats (SHR) were used address further explored biophysical properties underlying mechanisms. Long bones hind limbs from...

The influences of different geometries compartment, namely, round, hexagon, square, triangle, on drug release from also studied. morphology porosity determined scanning electron microscopy synchrotron radiation X-ray tomographic microscopy, respectively. Additionally, content evaluated. results...
This paper elucidated the microstructural and porosity evolution of alkali activated slag at 800 °C up to 1200 °C. The analysis obtained shows changes in surface densification glassy phase nucleation dynamical grains within when contact with high heating temperature. Using synchrotron radiation X-ray tomographic microscopy, number pores decreased increasing 3D distribution also demonstrated significant increase range size ~20 μm appearance isolated intergranular These led anorthite...
Abstract Battery cathode materials operating on multivalent‐ion intercalation are prone to short operational lifetimes, traditionally explained be due poor solid‐state diffusion. Here, we overcome this problem by using a conversion‐type material and demonstrate the benefits in FeVO 4 host structure. The rechargeable Zn‐ion battery exhibits stability for an unprecedented lifetime of 57 days with high capacity 272 mAh g −1 (60 mA ) over 140 cycles. We use combination synchrotron‐based XAS,...
Abstract Excessive salt intake has been associated with the development of non-communicable diseases, including hypertension several cardiovascular consequences. Although detrimental effects high on skeleton have reported, longitudinal assessment calcium balance together changes in bone microarchitecture and strength under loading not fully demonstrated. To address these unanswered issues, male Sprague–Dawley rats were fed normal diet (NSD; 0.8% NaCl) or (HSD; 8% for 5 months. Elevation...
Since 2020, synchrotron radiation facilities in several Asia-Pacific countries have been collaborating a major project called "SYNAPSE" (Synchrotrons for Neuroscience: an Scientific Enterprise). They use x-ray imaging to attack coordinated fashion one of the issues modern science: structure animal and human brains, including neurons connections. The objective is develop Google-like maps also detailed structural functional information selected regions interest. sheer mass data needed poses...
Zein is composed of nonpolar amino acids and a water-insoluble protein used as the matrix-forming agent localized in situ forming gel (ISG). Therefore, this study prepared solvent removal phase inversion zein-based ISG formulations to load levofloxacin HCl (Lv) for periodontitis treatment using dimethyl sulfoxide (DMSO) glycerol formal (GF) solvents. Their physicochemical properties were determined, including viscosity, injectability, formation, drug release. The topography dried remnants...
A drug delivery system based on an aqueous-induced in situ forming gel (ISG) consists of solubilizing the within organic solution a polymer using biocompatible solvent. Upon contact with aqueous medium, solvent diffuses out and polymer, designed to be insoluble water, solidifies transforms into gel. Nitrocellulose (Nc), nitrated ester cellulose, should promising for ISG water induction its state via phase inversion. The aim this investigation was develop evaluate moxifloxacin HCl...

YgjG is a putrescine aminotransferase enzyme that transfers amino groups from compounds with terminal primary amines to an aldehyde group using pyridoxal-5′-phosphate (PLP) as cofactor. Previous biochemical data show the prefers diamines, such putrescine, over ornithine substrate. To better understand enzyme's substrate specificity, crystal structures of Escherichia coli were determined at 2.3 and 2.1 Å resolutions for free putrescine-bound enzymes, respectively. Sequence structural analyses...
