IDENTIFIKASI UNSUR NIKEL DENGAN TEKNIK LASER INDUCED PLASMA (LIP) [PDF]

open access: yes, 2004
The line spectral of Ni element has been obtained for high and low concentration using Laser Induced Plasma (LIP) method. Focusing of high power pulse laser without pre treatment on the sample generates the Ni plasma contributed to atomic emission.

A comparative study of the effects of argon laser and continuous Nd: YAG laser on blood vessel

open access: yesمجلة بغداد للعلوم, 2010
Several types of laser are used in experimental works in order to study the effects of laser on blood vessel. They differ from each other by a lot of properties mainly in wavelength, energy of the laser and pulse duration.

Multisensorial Assessment of Laser Effects on Shellac Applied on Wall Paintings

open access: yesSensors, 2021
The assessment of five different laser treatments in the conservation of wall paintings was devised on the basis of the surface temperature monitoring by infrared thermography (IRT), ultraviolet-induced fluorescence-visible (UV-VIS) imaging, and optical ...

Alcohol‐Adduct Mediated Precursor Stabilization Strategies for Conformal SnO2 Layers in Highly Efficient and Stable Perovskite Solar Modules

open access: yesAdvanced Energy Materials, EarlyView.
An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

The Role of Pulse Energy On Laser Induced Secondary Plasma Generation [PDF]

open access: yes, 2005
An observation about the role of laser pulse energy on the secondary plasma generation has been point out. The plasma emission intensity as a function of laser pulse energy was detected by using a monochromator combined with photomultiplier tube.

Influence of various process conditions on surface finishes induced by the direct metal deposition laser technique on a Ti–6Al–4V alloy [PDF]

open access: yes, 2012
The direct metal deposition (DMD) with laser is a free-form metal deposition process for manufacturing dense pieces, which allows generating a prototype or small series of near net-shape structures. One of the most critical issues is that produced pieces

Laser Radiation Induces Growth and Lipid Accumulation in the Seawater Microalga Chlorella pacifica

open access: yesEnergies, 2017
The impacts of laser radiation (Nd: YAG laser, 1064 nm at 800 mW, He–Ne laser 808 nm at 6 W, semiconductor laser 632.8 nm at 40 mW) on growth and lipid accumulation of Chlorella pacifica were investigated in this study.

A Kinetic–Energetic Bottleneck of Charge‐Transfer Injection Governs Energy Loss in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Kinetic–energetic projection of time‐resolved photoluminescence reveals that charge‐transfer injection acts as a universal bottleneck in organic solar cells. A physics‐constrained Bayesian framework identifies an emergent effective CT injection rate governing the trade‐off between charge generation and nonradiative energy loss.

CO2‐Driven Synthesis of Holey Edge‐Carboxylated Graphene for Tunable Electronic Interactions in Cu–CeO2‐Catalyzed Water‐Gas Shift Reaction

open access: yesCarbon Energy, EarlyView.
Holey‐structured, edge‐carboxylated graphene with a controlled specific surface area was synthesized using an environmentally friendly, CO2‐activated, KOH‐free ball‐milling process. ABSTRACT Graphene, notable for its high specific surface area, is ideal for catalyst support but faces challenges under harsh thermal catalytic conditions.
