The XRD measurements were carried out to study the crystalline nature and phase purity of the phosphor materials by using CuKα radiation (λ = 0.15406 nm) based Rigaku diffractometer system. The surface morphology of phosphor was studied by SEM (Zeiss, Evo18 Research). The presence of different constituents in the phosphor samples was documented by EDS technique. The EDS mapping images were generated by using INCA software attached with INCAx-act Oxford Instruments (51-ADD0048). The UV–vis–NIR absorption spectra were studied in diffuse reflectance mode with the help of Perkin Elmer Lambda-750 (Ultraviolet–visible-Near infrared spectrometer) unit in the 200–1100 nm region. The FTIR spectra were monitored by using a Perkin Elmer IR spectrometer (I Frontier unit) in 400–4000 cm−1 range. The upconversion emission spectra were monitored with the help of 980 nm and also iHR320 Horiba Jobin Yvon spectrometer attached with PMT. The decay curves for 5F4 level of the Ho3+ ion were monitored by chopping continuous beam of 980 nm radiations with the help of a mechanical chopper and 150 MHz digital oscilloscope of Hameg instruments using Model No. HM1507. Finally, the phosphor materials were heated outside with the digital thermo-couple arrangements for analyzing the temperature sensing capability. The CIE diagrams of the phosphor samples were drawn with the help of GoCIE 1931 software.

The surface area, pore size,
and diameter of the BaBG were analyzed by the Brunauer–Emmett–Teller
(BET) and Barrett–Joyner–Halenda (BJH) methods during
nitrogen adsorption–desorption measurements (Quantachrome Instruments
NOVA 1000).24 (link) The mean diameter of synthesized
BaBG was determined using a particle size analyzer as previously reported.22 (link) Further, BaBG after incubation with SBF for
7 days was filtered followed by washing with deionized water and oven-dried
at 60 °C for 5 h. The formation of an HA layer was affirmed by
Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction
(XRD), and SEM–EDX. The phase analysis of BaBG before and after
treatment with SBF was determined by XRD (RIGAKU-Miniflex II diffractometer)
at 2θ, varying from 20 to 80° with a step size of 0.02°,
and the interpretation of peak was validated by utilizing the standard
JCPDS-International Centre for Diffraction Data Cards. Similarly,
the functional group present in BaBG and the newly formed HCA post
SBF treatment were characterized by FTIR (FTIR-8400S, SHIMADZU). The
surface morphology and changes in the elemental composition were evaluated
by SEM–EDX (EVO/18 Research, ZEISS).

The fungal isolate was initially identified using scanning electron microscopy (EVO/18 Research, Carl Zeiss) to examine morphological parameters, spore structure, and surface morphology. The culture development profile, spore colors, and morphologies were examined using standard guides. The fungal strain was characterized by the Lacto phenol cotton blue method and detected in the microscope.

Scanning electron microscope (SEM) morphological analyses were carried out on the fractured surface of the wire pull-out test sample for this study. These 4 types of treatment were examined with the same fibre loading of 3.0% point. The total five samples collected from the wire pull-out specimen were also tested. To improve resolution, platinum was applied to the samples, which has a high electrical conductivity. The micrograph was attained owing to the use of Zeiss Evo 18 Research, (Jena, Germany) with an acceleration voltage of 10 kV.
The measurement of the diameter for filament was by using a portable microscope up to 1600 magnification, which has many functions, including a measurement size from 0.001 mm to 50.00 mm. This method was used for 5 sample filaments, which are r-PP, untreated, and treated wood.

Fresh plant samples were harvested on the 5th and 10th days of treatment, and then the fresh leaves were cut into small pieces for sample preparation to study the stomatal structure. Afterwards, the leaves were fixed in the first fixative solution i.e., glutaraldehyde solution, for 2–3 h with pH 7.4. After the fixation step, the next step that followed was dehydration, in which the samples were dehydrated with an ethanol series ranging from 95% ethanol to 50% ethanol.

FTIR was conducted using the FTIR spectrophotometer (Perkin Elmer Frontier) for functional groups in the frequency range of 4,000–400 cm−1. The pellet was prepared using KBr (FTIR grade), and the sample was thoroughly crushed and mixed in a mortar and further pressed using a pellet press machine (Fan et al., 2012 (link)). Thermal gravimetric analysis (TGA) was conducted to determine the thermal stability of untreated and treated samples used for experiments using a thermogravimetric analyzer (Perkin Elmer/TGA 4000) with a maximum temperature of 900°C and heating rate of 10°C min−1 under a nitrogen atmosphere. The weight change of corn stover biomass was recorded following temperature and time. A 2 g sample of dried powder was placed in the crucible in the analyzer (Velázquez-Martí et al., 2018 (link)). The morphology of untreated and treated samples was determined using a scanning electron microscope (ZEISS EVO 18 Research) (Shamala et al., 2009 (link)).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
