Four starch-encapsulated formulations of EPTC(S-ethyl dipropylthiocarbamate) and of butylate(S-ethyl diisobutylthiocarbamate) were prepared and evaluated by comparison with their respective emulsifiable concentrate formulations for their slow-release capabilities and efficacies. Chemical and biological evaluation indicated that difference in controlled-release could be achieved by the selection of the starch xanthate and oxidant used in the formualtion process. EPTC and butylate released slower when formulated as starch-encapsulated granules than when formulated as emulsifiable concentrates under soil conditions that favored rapid release. The initial release was adequate for weed control and slow enough for desired residual activity. Repeated seeding and harvesting the treated soils and bioassays of treated soils generally produced release rate anticipated from short term dry and wet chemical tests.

The current study aims to explore and identify the screening of formulation components and evaluates the quality issues of nanostructured lipid carriers (NLCs) for the phenolic secoirodoid Oleuropein. The stepwise screening of the components for preparation of NLCs includes the selection of solid lipid, liquid lipid based on the relative solubility of Oleuropein in different lipids. Polaxomer 188 was selected as the main surfactant for the preparation of NLCs because of its good emulsification efficacy for the solid lipid liquid mix. Lecithin was used to enhance the stability of NLC. The optimized formulation was also evaluated for different quality issues. Thermal analysis by DSC revealed that the lipid particles maintained sufficiently good melting point even after nanonization. Absence of gelation and resilience for the stress provided by autoclaving further established the quality of the developed NLCs. In a nutshell, a systematic protocol was developed for designing of Oleuropein NLC with good particulate parameters of minimum particle size and maximum zeta potential with narrow polydispersity index.

Abstract Thermal analysis of laser processes can be used to predict thermal stresses and consequently deformation in a completed part. Analysis of temperature is also the basic for feedback of laser processing parameters in manufacturing. The quality of laser sintered parts greatly depends on proper selection of the input processing parameters, material properties and support creation. In order to relatively big heat stress in the built part during sintering process, the thermal simulation and thermal analysis, which could help better understand and solve the issue of parts deformations is very important. Main aim of presented work is to prepare input parameters for thermal simulations by the use of RadTherm software (Thermoanalytics Inc., USA), directly during the sintering process and after the process and find out the impact of the heat stress on a final shape and size of the prototype. Subsequently, an annealing process of constructed products after DMLS could be simulated and specified.
