soflavones, a special phenolic group found in soybean, have been found to act as antioxidant and are widely used in pharmaceutics and nutraceuticals. Due to the storage and handling problem, the extract has been prepared in dry form by spray drying technique. The condition of extract solution prior to spray drying has been reported to affect the property of dried powder. The aim of this work was to evaluate the effect of diluents on the physical properties of soybean extracted powder. The experiment was carried out by a Büchi B-290 Mini Spray Dryer. Four types of diluents were applied, they weremannitol, maltrodextrin, and 2 types of modified starch The comparison was then made among those with diluents and without diluent as a carrier. The physicochemical property was then characterized for flowability, moisture content, morphology, particle size and X-ray diffraction. From the results, the addition of all diluents could improve the physicochemical properties of soybean extracted powder indicating the improvement in morphology and hence the better flow property .The types of diluent also had the effect on the extracted powder. Maltodextrin and modified starch exhibited the best carrier in term of improvement of flow property. Therefore, the spray drying technique was successfully used to prepare microparticles of soybean extracted powder and by taking into consideration of the selection of suitable diluents, the good quality of soybean extracted powder could be achieved.

The silica potassium humic substance (Si-K-HAs) composite have been produce by spray drying successfully. In the previous study the preparation of Si-K-HAs gel by precipitation method required the addition of acid so that Si-K-HAs gel product contains acid salts. This study was develope spray drying method in order to eliminate the use of acid. The mixture of potassium silicate, cellulose and humic potassium solution was mixed with varying volume ratios and flowed into a spray dryer to produce Si-K-HAs powder. The used of cellulose (CMC) in this study acts as a homogeneous agent so that silica and humic substance can be completely mixed at controlled viscosity. Si-K-HAs products were characterized by Scanning electron microscopy (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier transform infrared spectrometry (FTIR), and Surface area analytical (SAA). The result showed that the Si-K-HAs composite prepared by spray dryers have spherical particles, SiO2 in the range of 48-50%, K2O in the range of 49-50%. The present of cellulose caused the increasing of Si-K-HAs particle size e.g 17.30 μm prepared without CMC to 41.11 μm prepared with addition of 100g of CMC. The presence of cellulose can also increase the surface area of the spray-dried Si-K-HAs particles from 111.92 m2g-1; 163.241 m2g-1.

Spray drying method was used to prepare cocrystals of hexanitrohexaazaisowurtzitane (CL-20) and cyclotetramethylene tetranitramine (HMX). Raw materials and cocrystals were characterized using scanning electron microscopy, X-ray diffraction, differential scanning calorimetry, Raman spectroscopy, and Fourier transform infrared spectroscopy. Impact and friction sensitivity of cocrystals were tested and analyzed. Results show that, after preparation by spray drying method, microparticles were spherical in shape and 0.5–5 µm in size. Particles formed aggregates of numerous tiny plate-like cocrystals, whereas CL-20/HMX cocrystals had thicknesses of below 100 nm. Cocrystals were formed by C–H⋯O bonding between –NO2 (CL-20) and –CH2– (HMX). Nanococrystal explosives exhibited drop height of 47.3 cm, and friction demonstrated explosion probability of 64%. Compared with raw HMX, cocrystals displayed significantly reduced mechanical sensitivity.

Abstract – Bio-solar is one of the natural gemstones found in the province of Aceh in Indonesia. A recent study suggested that this gemstone could be considered as a vesuvianite type of gemstone. Nevertheless, detail information of this bio-solar gemstone is still unknown. We do not know whether the bio-solar gemstone is crystalline or amorphous. The specific gravity and the hardness of this gemstone are also still unknown. This information is essential to determine the quality of a gem. To answer those questions, we have used x-ray diffraction to study the bio-solar gemstone from the province of Aceh in Indonesia. The physical properties (specific gravity and hardness) of this gemstone have also been measured. We found that the bio-solar gemstone is composed by CaO, SiO2, MgO, Al2O3, Fe2O3, and TiO2 phases. Our results revealed that the bio-solar gem is a crystalline material, not amorphous. The average crystallite size of this gemstone is found to be 353 Å (35 nm). Moreover, the specific gravity of bio-solar gemstone is found to be 3.09 – 3.34. Its hardness is 3 to 4 mohs. Thus, the bio-solar is a good quality gemstone. Our finding confirmed that the bio-solar could be classified as a vesuvianite gemstone.

Sari pandan merupakan hasil ekstraksi daun pandan. Sari pandan siap pakai yang beredar di Indonesia mayoritas berbentuk pasta, yang memiliki beberapa kelemahan, diantaranya mudah rusak, lengket, dan susah ditakar. Pembuatan sari pandan dalam bentuk bubuk diharapkan dapat meningkatkan mutu sari pandan. Metode yang digunakan dalam penelitian ini adalah pengeringan spray drying dan pengeringan vakum. Pengujian kadar air menunjukkan bahwa sari pandan yang dibuat dengan metode spray drying memiliki kadar air yang lebih rendah daripada metode pengeringan vakum. Pengamatan sifat fisik sari pandan dalam kondisi siap pakai menunjukkan bahwa metode spray drying menghasilkan warna dan aroma sari pandan yang lebih kuat daripada metode pengeringan vakum. Uji organoleptik menunjukkan bahwa panelis lebih menyukai warna dan aroma sari pandan yang dibuat dengan metode spray drying. Pandan extracts is made from pandan leaves. The majority of ready-to-use pandan extracts in Indonesia are in the form of pasta which has several disadvantages, including perishable, sticky, and hard to be measured. Pandan extract in powder form is expected to improve the quality of the pandan extract. The method used in this study are spray drying and vacuum drying. Water content analysis shows that pandan extract made by spray drying method has a lower moisture content than the vacuum drying method.

ABSTRACTClay-polymer nanoparticulate composite materials are evaluated by the X-ray diffraction technique. The basal plane spacing provided information about the degree of intercalation and exfoliation of the 2: 1 layered clay structure. Both intercalation and exfoliation are controlled by the identity of the polymer and the clay:polymer ratio.

Mullite Phase

Kaolin M1 and M2 studied by X-ray diffraction focus on the mullite phase, which is the main phase present in both products. The Williamson–Hall and Warren–Averbach methods for determining the crystallite size and microstrains of integral breadth β are calculated by the FullProf program. The integral breadth ( β) is a mixture resulting from the microstrains and size effect, so this should be taken into account during the calculation. The Williamson–Hall chart determines whether the sample is affected by grain size or microstrain. It appears very clearly that the principal phase of the various sintered kaolins, mullite, is free from internal microstrains. It is the case of the mixtures fritted at low temperature (1200 °C) during 1 h and also the case of the mixtures of the type chamotte cooks with 1350 °C during very long times (several weeks). This result is very significant as it gives an element of explanation to a very significant quality of mullite: its mechanical resistance during uses at high temperature remains.

This study evaluates the physical properties of freeze dried tropical (guava, sapota, and papaya) fruit powders. Thermal stability and weight loss were evaluated using TGA-DSC and IR, which showed pectin as the main solid constituent. LCR meter measured electrical conductivity, dielectric constant, and dielectric loss factor. Functional groups assessed by FTIR showed presence of chlorides, and O–H and N–H bonds in guava, chloride and C–H bond in papaya, and chlorides, and C=O and C–H bonds in sapota. Particle size and type of starch were evaluated by X-ray diffraction and microstructure through scanning electronic microscopy. A semicrystalline profile and average particle size of the fruit powders were evidenced by X-ray diffraction and lamellar/spherical morphologies by SEM. Presence of A-type starch was observed in all three fruits. Dependence of electric and dielectric properties on frequency and temperature was observed.
