2. Klasifikasi Katalis Katalis memiliki 3 macam klasifikai yaitu katalis homogen, katalis heterogen, dan enzim. Perbedaan ini berdasarkan penggunaan katalis pada suatu reaksi. f Katalis homogen Katalis homogen ialah katalis yang memiliki fasa yang sama dengan reaktan dan produk yang dihasilkan. Biasanya katalis homogen berupa fasa cair dimana
Hydrogel merupakan kristal polimer yang biasa digunakan sebagai media tanam bagi tanaman hidroponik. Penggunaan media tanam jenis ini sangat mudah dan efesien karena tidak perlu untuk mengganti, menyiram atau memupuk. Biasanya, hydrogel digunakan untuk menanam tanaman hias didalam ruangan, karena memiliki berbagai warna dan berbentuk.

Hydrogel is a 3D polymeric network with high water content (>90%), whose rheological properties (i.e., the law of flow or deformation of materials under external factors (e.g., stress, strain

Intelligent hydrogels, also known as stimuli-responsive hydrogels, are three-dimensional networks made up of polymerised hydrophilic polymer networks that may substantially vary their volumes and other properties in response to external stimuli like temperature, pH, and specific chemical signals. 16 The adaptability of smart hydrogels depends on their ability to respond quickly and effectively
Hydrogels have three-dimensional network structures that have been widely applied owing to their high water content, excellent biocompatibility, and physicochemical properties. Compared with conventional hydrogels, sprayable hydrogels exhibit excellent temporal and spatial controllability. Biomass materials offer easy accessibility, biocompatibility, biodegradability, and other
Hydrogel wound dressings promote healing, provide moisture, and offer pain relief with their cool, high water content. This cooling effect on the skin helps manage conditions such as chicken pox and shingles, and when saturated onto a gauze pad, the hydrogel will prevent dressings from sticking to the wound surface.
