This articles is comprised of two parts: a) an experimental investigation on the behavior of an acrylic gel under DC electric field and b) a physico - mathematical description.a) Gel rods made of poly [acrylamide-co-bisacrylamide] were partially hydrolyzed to different extents at pH 12 by teteramethylethylene diamine. Equlibrium properties of the resulting gels rods (water content,...

biology teachers at Taman Mulia Kubu Raya School, project-based student worksheets (LKPD) in making hand sanitizer gels and also did not have experience kesum leaf gels. This study aims to develop a LKPD manufacture of gel on biotechnology materials. Research is the development Thiagrajan with amodified 4D model into 3D. that are developed feasible based percentage eligibility for media, materi...

the objective of the present work was to formulate and evaluate mucoadhesive in situ nasal gels of loratadine. this drug delivery system may overcome the first-pass metabolism and subsequently improve the bioavailability of the drug. a total of 16 formulations of in situ nasal gels were prepared using different polymeric ratios of hydroxypropyl methylcellulose (hpmc k-100) and xanthan gum. all ...

The design of 3D culture studies remains challenging due to the limited understanding of extracellular matrix (ECM)-dependent hindered diffusion and the lack of simple diffusivity assays. To address these limitations, we set up a cost-effective diffusivity assay based on a Transwell plate and the spectrophotometer of a Microplate Reader, which are readily accessible to cell biology groups. The ...

Hybrid polymer-network gels built by both physical and covalent polymer crosslinking combine the advantages of both these crosslinking types: they exhibit high mechanical strength along with excellent fracture toughness and extensibility. If these materials are extensively deformed, their physical crosslinks can break such that strain energy is dissipated and irreversible fracturing is restrict...

Two proteins with known characteristics on one-dimensional gels were studied by two-dimensional electrophoresis to compare the sensitivities of the two methods in detecting genetic variation. Two-dimensional electrophoresis was found to be less sensitive than several types of one-dimensional gels in distinguishing variants of both proteins. Denaturation of proteins in urea in the two-dimensiona...

Prior studies indicated that mechanical loading influences cell turnover and matrix remodeling in tissues, suggesting that mechanical stimuli can play an active role in engineering artificial tissues. While most tissue culture studies focus on influence of uniaxial loading or constraints, effects of multi-axial loading or constraints on tissue development are far from clear. In this study, we e...
