Abstract

Laboratories are complex environments, where social interactions and professional demandsblend with performance pressures and organizational hierarchies. Behind the seeminglyobjective scientific activity, there are emotional dynamics that influence individual behavior,one of which is embodied shame. Based on concepts discussed by Ruebottom and Toubiana(2024), this article explores the impact of shame on laboratory management. Internalizedshame can negatively impact laboratory dynamics by inhibiting collaboration, loweringemotional energy and creating a less productive work environment. Individuals who feelshame tend to shrink emotionally and physically, which inhibits their potential to innovate andcollaborate effectively. To address this issue, labs must create a psychologically safeenvironment, where members feel supported and free from fear to conduct experiments.Inclusive leadership that supports all groups, as well as providing opportunities for reflectionand personal growth, can help reduce internalized shame. With the right managementstrategies, laboratories can become more inclusive and supportive places, which not onlyimproves the emotional well-being of laboratory members, but also fosters scientificinnovation and better collaboration

Abstract

Purpose – This study aims to characterize rice husks as a renewable energy source. It measures the absorption and absorbance of rice husk waste. It determines the factors that affect the efficiency of rice husks (RHS) as a renewable energy source. Design/methods/approach – Laboratory experiments and literature reviews were the methods used in this study. Material characterization was performed using a Vector Network Analyzer (VNA) to measure electromagnetic wave absorption and a UV-VIS spectrometer to measure UV absorption. Findings – The results of the VNA measurement of RHS HCl 0M carbon = -3.80 dB; 1M = -13.28dB, and 3M = -12.28 dB. Absorbance measurements were then performed using UV-Vis. Based on the measurements performed, the absorbance values of each material were as follows: RH HCl 0M = 0.187 AU; 1M = 0.084 AU; 3M = 0.141 AU. Research implications/limitations – Exploring the potential of rice husks as an environmentally friendly and sustainable renewable energy source. Analyzing the physical and chemical characteristics of rice husks, including their carbon content, to determine the energy efficiency that can be generated through various conversion technologies such as combustion, activation, and measurement. Originality/value – This study focuses on the potential of rice husks as a renewable energy source.
