Abstract

MICROWAVE-ASSISTED CENTRIFUGAL SPINNING OF GELATIN MICROFIBERS. Herein, we disclose a method for preparing polymeric microfibers. According to an embodiment of the method, gelatin fibers were prepared from 50% aqueous gelatin solution by centrifugal spinning. The produced material feels similar to wool to the touch. Average fiber diameter was determined to be 40 μm. Thermal stability of the material is similar to that of gelatin fibers prepared by other techniques, e.g. electrospinning. Elastic modulus of the fibrous material was determined to be 230 MPa and its toughness was found to be 160 kJ/m3. The described method is one of the fastest low-cost lab-scale fiber production techniques available (as a practical example, the speed of fiber production was roughly 5 g/s) and could be used to prepare various polymeric fibers in an eco-friendly way for a wide range of applications, including textile industry, tissue engineering and drug delivery.

Abstract

SYNTHESIS AND CHARACTERIZATION OF LiFePO4/PPy/CLAY COMPOSITE AS CATHODE MATERIAL FOR Li-ION BATTERY. Conductor polymers have been used previously as a conducting agent or carbon source in various sol-gel and solid state methods to increase the conductivity of LiFePO4. The composite of LiFePO4/PPy/Clay were synthesized by mixing LiFePO4 and clay with a Ppy solution. The characterizations were done by using X-Ray Diffractometer (XRD), Scanning Electron Microscope (SEM) and LCR meter respectively. From XRD analysis it could be deduced that LiFePO4 has an ordered olivine structure with a Pnma space group. The SEM images provide clear evidence that small crystal particles of LiFePO4 either coat the surface of the clay particles or lie among them. These LiFePO4 particles have a small particle size (100–500 nm). With the increasing of LiFePO4 content, these small crystal particles at the surface or among the clay particles are increased. Increasing the PPy content to increase the conductivity of the material obtained. With the addition of clay from 5 to 10 wt. %, the DC conductivity of the blends is clearly observed to increase up to three orders of magnitude.

Abstract

EFFECT OF ANNEALING CYCLES ON DEEP DRAWABILITY OF LOW CARBON TITANIUM ADDED STEEL. Maximum mechanical properties and deep drawability of low carbon titanium added steels was obtained after heat treatment with simulation batch annealing cycles in an industrial process. The effect of holding times and holding temperatures on deep drawability were studied using tensile test for measuring normal anisotropy (r-value) and strain hardening exponent (n-value). Scanning electron microscope were employed for observation of microstructure in steel sheets. X-ray diffraction with pole figure techniques were also used for measuring texture of annealing. Results showed that as the temperature was increased up to 900 oC, both r and n values increased gradually and peaked in the temperature of 850 oC. This results showed that formability of sheet materials increased until batch annealing temperature reach 850 oC as increasing the ratio of intensities {111} /{100}. The largest mean r value of almost 2.6 was obtained in slow heating at holding temperature of 850 oC with n value of 0.27.

Abstract

Lignin was recovered from black liquor during the biorefinery process and has prospective applications in pharmaceutical, cosmetic, and health care. Lignin, which has substantially smaller particles, was used as the active ingredient in the sunscreen cream formulation. The isolated lignin was examined for physicochemical parameters such as yield, purity, particle size, total phenol, and morphology. The obtained lignin was used in the preparation of sunscreen cream. The isolated lignin concentration in the cream varied between 0.1, 1, and 2 wt%. The sun protection factor (SPF) of the designed sunscreen creams was assessed, and antioxidant activity and stability were studied, which included pH, particle size, and appearance during the observation period. The formulated cream has an SPF of approximately 15, which is sufficient to protect human skin from the sun's UV radiation. Furthermore, the most significant antioxidant activity was found to be 68.94%. As a result, the developed sunscreen cream has the potential for further research because it is composed of natural active ingredients that are safe for humans and the environment.

Abstract

EFEK ANIL SUHU RENDAH PADA TERFENOL-D YANG DIBUAT DENGAN METODE REDUKSI-DIFUSI — Dalam kegiatan ini dipelajari efek anil suhu rendah pada paduan magnetostriktif yang diperoleh dengan metode Reduksi-Difusi (RD). Diharapkan bahwa apabila cuplikan sebelumnya mengandung fasa sekunder berupa hidrida, fasa tersebut dapat dihilangkan dengan perlakuan anil tersebut. Anil dilakukan pada suhu 200°C, selama 8 jam, dalam vakum dinamis pada cuplikan berbentuk pelet yang dibungkus dalam lembaran Tantalum. Dalam ruangan cuplikan diletakkan pula 'getter' yaitu Ti murni. Hasil analisis data XRD menunjukkan beberapa aspek: pertama, ada kecenderungan penyempitan puncak-puncak difraksi setelah anil. Diduga ini akibat 'internal stress relieve', karena pada suhu anil tersebut, tidak ada perbaikan tingkat kristalisasi sampel. Kedua, fasa hidrida dapat dihilangkan melalui perlakuan anil ini, dan ketiga, pada cuplikan tertentu terlihat ada pergeseran posisi puncak-puncak difraksi fasa utama ke arah sudut yang lebih besar, menandakan bahwa fasa utama tersebut pada awalnya juga mengandung hidrogen dalam jumlah yang sangat kecil, yang belum pernah terdeteksi sebelumnya. Sebagai kesimpulan, perlakuan anil tersebut memberikan dampak positif pada cuplikan Terfenol-D, dan merupakan modifikasi penting dari metode sintesis Reduksi-Difusi.

Abstract

Silicon, a ubiquitous element in modern electronics, underpins the operation of countless devices due to its unique semiconducting properties. However, as device dimensions shrink to the nanoscale, silicon-based devices face limitations such as increased power consumption and decreased performance. Coating silicon with graphene is aimed to improve the device performance and extend the limits of silicon’s performance. Conducting experimental work involving graphene for thin coatings is a resource-intensive process. Hence, molecular dynamics (MD) simulation is necessary to illuminate the evaporation and coating mechanisms at the atomic scale, serving as a valuable tool for experimental design. These molecular dynamics simulations have elucidated the intricate relationship between temperature and deposition time in governing the quantity and spatial distribution of carbon atoms on a silicon substrate. Within a 300 ps deposition interval, a non-linear correlation between temperature and carbon deposition is observed, indicating that the allotted time is insufficient for complete atomic diffusion and homogeneous distribution. At elevated temperatures, carbon atoms accumulate, impeding the diffusion of subsequent atoms. Conversely, a 600 ps deposition period reveals a direct proportionality between temperature and carbon deposition, attributed to the enhanced mobility of carbon atoms, facilitating their dispersion and creation of vacancies within the substrate.

Abstract

The main objective of the work is to substitute SeaNine 211 in self-polishing antifouling (SPA) paint formulations for marine coating using cerium oxide as a co-biocide. The development of SPA paint with cerium oxide as a co-biocide is expected to significantly improve the environmental friendliness and efficacy of antifouling paints. The preparation of modified SPA paint was undertaken by incorporating the cerium oxide with various concentrations (0.1, 0.3, and 0.5 wt.%) in the SPA paint formulation without SeaNine 211. The copper dissolution rate determines the efficacy of antifouling paint, where the greater the copper release rate, the greater the efficacy of the antifouling paint. The leached-out test results obtained suggest that with an increase of 0.1% wt in the concentration of cerium oxide, there was an improvement in the copper dissolution rate. It was also observed that the mild steel specimens were coated with modified SPA paint when immersed in the seawater for 7 days for testing. The properties were observed by utilizing scanning electron microscopy (SEM). An improvement in the copper dissolution rate was found, as shown by cerium oxide SPA paint when contrasted with bare paint. The contact angle test finding also suggests that adding 0.1% wt of cerium oxide to the SPA paint will increase the dissolution rate of copper. This work could provide insight into developing an environmentally friendly antifouling paint co-biocide.
