Controlling the concentration of defects in reduced graphene oxide （rgo） to tailor its electrical and physicochemical properties has remained a significant challenge. We report that extent of microwave （MW）-driven annealing of rgo is influenced significantly by its bulk density, which allows us to vary its defect density and crystallite size over wide ranges by controlling this parameter. Extent of anneal- ing was investigated by multiple techniques including raman and X-ray photoelectron spectroscopies, and electrical conductivity measurements. Improved corrosion resistance of rgos upon annealing was ex- amined by cyclic voltammetry in H_2sO_4 electrolyte and temperature-programmed oxidation of rgo. Our results indicate that a low bulk density of rgo facilitates defect annealing, yielding high-quality carbon with 99.3 wt% purity, oxidative resistance as high as graphite powder, and an electrical conductivity of 36,000 s m-1 in the compressed powder form. These results demonstrate a prospective synthesis route for tailor-made nanocarbons from rgo through MW-driven annealing.

The development and applications of a ruggedized visible to near-infrared （VIs/NIr） spectrometer system capable of measuring fluid spectra in oilfield wellbores are presented. real-time assessment of formation fluid properties penetrated by an oilfield wellbore is critically important for oilfield operating companies to make informed decisions to optimize the development plan of the well and hydrocarbon reservoir. A ruggedized VIs/NIr spectrometer was designed and built to measure and analyze hydrocarbon spectra reliably under the harsh conditions of the oilfield wellbore environment, including temperature up to 175 ~C, pressure up to 170MPa, and severe mechanical shocks and vibrations. The accuracy of hydrocarbon group composition analysis was compared well with gas chromatography results in the laboratory.

Nd-doped srA1204 （Nd：srA1204） crystals were prepared by a floating zone （FZ） method with different dopant concentra- tions. The photoluminescence （PL） measurements under visible light excitations confirmed strong near infrared （NIr） emissions around 890 nm, which is due to the 4f-4f transitions of Nd3＋, and the decay time constants were 300-400 μs. Furthermore, VUV ex- citations revealed two broad emissions around 250450 and 500-700 run, which were attributed to self-trapped excitons （sTEs） perturbed by Nd3＋. Moreover, the X-ray induced scintillation spectra showed some small peaks at around 380 nm in addition to NIr emissions at 1064 nm similarly seen in PL. The former scintillation decay time constants were 30-40 Its. In the undoped sample, these emissions mentioned above were not present but a weak broad emission around 450 nm appeared. In thermally stimulated lu- minescence （TsL） after X-ray irradiation, strong TsL glow peaks were observed in the Nd-doped samples at around 100 and 250 ℃.

Over the past two decades, the CICECO-hub scientists have devoted substantial efforts to advancing bioactiveinorganic materials based on calcium phosphates and alkali-free bioactive glasses. A key focus has been thedeliberate incorporation of therapeutic ions like Mg, sr, Zn, Mn, or Ga to enhance osteointegration and vascularization,confer antioxidant properties, and impart antimicrobial effects, marking significant contributions tothe field of biomaterials and bone tissue engineering. such an approach is expected to circumvent the uncertaintiesposed by methods relying on growth factors, such as bone morphogenetic proteins, parathyroidhormone, and platelet-rich plasma, along with their associated high costs and potential adverse side effects. Thiscomprehensive overview of CICECO-hub’s significant contributions to the forefront inorganic biomaterials acrossall research aspects and dimensionalities (powders, granules, thin films, bulk materials, and porous structures),follows a unified approach rooted in a cohesive conceptual framework, including synthesis, characterization, andtesting protocols. Tangible outcomes [injectable cements, durable implant coatings, and bone graft substitutes(scaffolds) featuring customized porous architectures for implant fixation, osteointegration, accelerated boneregeneration in critical-sized bone defects] were achieved. The manuscript showcases specific biofunctionalexamples of successful biomedical applications and effective translations to the market of bone grafts foradvanced therapies.
