Recording on Passive Capillary Flow of Dyed Working Liquids in the Polymer based Microfluidic Devices Fabricated inside the Cleanroom Laboratory
Abstract: In this experimental work, author has fabricated total 13 individual microfluidic devices using the maskless lithography, hot embossing lithography, direct bonding technique, diamond like carbon (DLC) coating, and laboratory-made clamping inside the cleanroom laboratory using author’s own hands-on completely. Polymethylmethacrylate (PMMA) is the chosen polymer to fabricate the 10 individual microfluidic devices due to its plasticity and optical transparency. Dyed water, dyed ethylene glycol and dyed ethanol are the prepared …

Experimental Studies on the Surface-Driven Capillary Flow of Dyed Water in Multistage Microfluidic Bends
Abstract: AbstractA single three-stage and a pair of two-stage microfluidic bends are fabricated. SU-8 as negative photoresist is used to fabricate the stamp by maskless lithography and diamond like carbon (DLC) coating. Microchannel structures are fabricated using polymethylmethacrylate (PMMA) by hot embossing lithography. Direct bonding technique is used to fabricate the leakage-free sealing in microfluidic bends. The leakage-free surface-driven capillary flow is recorded by CMOS camera. This work will be useful …

Mechanism of Intensive Gas and Fluid Mixture in the Process of Vibroturbulization and Its Technological Applications
Abstract: Previously conducted experimental studies have established that in a certain narrow frequency range and upon reaching a certain value of the amplitude of water oscillations in a sealed vessel with above-water air shell, subjected to vertical vibration, a resonant phenomenon occurs, called “vibroturbulization”, leading to intensive mixing of media of different density. The studies carried out were purely experimental in nature and could not reveal the physicochemical mechanism of occurrence, …

Preparation and Physico-chemical Analysis of Apasmarari Rasa – An Ayurvedic Formulation
Abstract: AbstractApasmarari Rasa, a unique Ayurvedic preparation has the main ingredients like Hingulottha Shuddha Parad (HSP), Shuddha Gandhaka (SG) and Shuddha Tuttha (ST) and Bhavana Dravya (trituration) as Tinospora cordifolia (Guduchi). The Chakrikas (pellets) prepared after giving bhavana to the above-mentioned ingredients, were sealed in Sharava (shallow earthen disc) Samputa (uniform smeared and dried) and subjected to Agni. After self-cooling (Swangasheeta), the mixture was triturated with Musa paradisiaca Linn (Kadali Kanda …

Minimal Invasive Approach in Periodontal Therapy: A Review
Abstract: Minimally invasive periodontal treatment procedures are mostly confined within the context of periodontal surgery and aim to perform less extensive surgical manipulation, leading to reduced level of pain and discomfort. It also prevents the delirious esthetic changes that could occur with the conventional surgical approaches. This review deals with the ground understanding of minimally invasive periodontal therapy inculcating the regenerative potential at the confined site, when performed. Many studies reveal …

Thermo-Responsive Polymer Blends for Minimally Invasive Medical Procedures
Abstract: Thermo-responsive polymer blends have become a key new class of biomaterials for the minimally invasive medical procedure. They offer precision, flexibility and greater patient safety. These smart materials undergo a change of physical/ mechanical properties relative to temperature difference in the body, limiting tissue trauma and increasing effectiveness of the procedure. Their adjustable sol-gel behavior, shape-memory effects and reversible volume change provides an opportunity for their precise delivery through catheters, …

A Ventilated Dual-Function Photonic–Phononic Metasurface for Simultaneous Passive Radiative Cooling and Low-Frequency Noise Mitigation in Building Envelopes: Conceptual Design and Computational Feasibility Analysis
Abstract: Acoustic metamaterials for sound insulation and photonic/radiative-cooling metamaterials for passive thermal management have each matured separately for building-envelope retrofit, but existing studies address ventilation, acoustic damping and radiative thermal control in isolation, and no reported unit-cell architecture co-designs all three within a single shared structure. This gap persists because materials that are acoustic absorptive are generally dense and structurally opaque, whereas materials that are highly solar-reflective are conventionally applied to …

Well Integrity and Reservoir Behavior under Sudden Field Shutdowns During Armed Conflicts: A Comprehensive Technical Review
Abstract: In the oil and gas industry, the sudden and unplanned cessation of operations resulting from armed conflicts or pandemics typically poses complex and multifaceted technical challenges to both well integrity and reservoir behavior. Minimal or no opportunity for proper pre-shutdown preservation procedures in unplanned shutdowns, unlike planned shutdowns that follow established operational protocols. The mechanisms and consequences of well integrity degradation and reservoir performance alteration under such conditions are synthesized …
