Diagonalization of Matrix

Diagonalization of 2×2 Matrix using Similarity (SAS⁻¹ / S⁻¹AS) Diagonalization of a 2×2 Matrix using Similarity Transformation Method: Choose eigenvectors as columns of \(S\), then compute \(D = S^{-1}AS\) (equivalently \(A = SDS^{-1}\)). Given \[ A=\begin{pmatrix}5&4\\[2pt]1&2\end{pmatrix} \] We will diagonalize \(A\) using \(D=S^{-1}AS\), where \(S\) is formed from eigenvectors. Step 1 Find the eigenvalues Characteristic equation: \(\det(A-\lambda I)=0\) \[ \det(A-\lambda I)= \begin{vmatrix} 5-\lambda & 4\\ 1 & 2-\lambda \end{vmatrix} =(5-\lambda)(2-\lambda)-4 \] \[ =(10-7\lambda+\lambda^2)-4=\lambda^2-7\lambda+6 \] ...

MOF trial

Lab Handout: Zn–Histidine Bio-MOF Synthesis (Beginner SOP) LAB HANDOUT (Beginner SOP) Synthesis of Zn–Histidine Bio-MOF (Real Metal–Organic Framework / Coordination Framework) Target output: ≥ 4 g (by combining 2 identical batches)  |  Recommended level: MSc Nanoscience project  |  Balance: 4-digit (0.0001 g) OK 1) Objective To synthesize a real MOF / coordination framework using Zn 2+ (metal node) and L-histidine (organic linker) under controlled pH. The key is to keep pH around 6.5 so that we form a coordination network (MOF) and avoid Zn(OH) 2 / ZnO formation . 2) Safety (Mandatory) Wear lab coat, gloves, and goggles throughout. NaOH is corrosive —add slowly; wash spills immediately with plenty of water. Autoclave safety: do not fill above 80%; do not open while hot/pressurized; cool naturally. Dispose washings as instructed (d...
